  • Indigenous HPV vaccine, the rhetoric and the reality

    Why in the news?

    Recent discourse suggests HPV vaccination prevents cervical cancer, but evidence linking HPV to cancer is inconclusive and most infected individuals don’t develop cancer, raising doubts about vaccine necessity.

    What is Cervical Cancer?

    Cervical cancer is a type of cancer that starts in the cells lining the cervix, which is the lower part of the uterus that connects to the vagina. It is usually a slow-growing cancer that may not have symptoms in its early stages.

    Present  trends of cervical cancer prevalence in India and the Globe                

    • Global Trends: Cervical cancer is the fourth most common cancer among women globally, with an estimated 604,000 new cases and 342,000 deaths reported in 2020. 
      • Mortality rates vary widely by region, with the highest rates observed in low- and middle-income countries due to limited access to screening and treatment.
    • Trends in India: In India, cervical cancer is the second most common cancer among women aged 15-44 years. It accounts for approximately 17% of all female cancer deaths in the country, with over 97,000 new cases reported annually.

     

    Recent debate – How does vaccination against HPV prevent cervical cancer and consequent death?                                                       

    • Efficacy Against HPV Infection and Cervical Cancer: HPV vaccines target high-risk HPV types, notably types 16 and 18, which are responsible for a significant proportion of cervical cancer cases worldwide. 
      • Clinical trials and real-world data consistently demonstrate the effectiveness of HPV vaccines in reducing HPV infection rates and preventing cervical cancer.
    • Public Health Impact and Benefits: Countries with high HPV vaccination coverage have observed significant declines in HPV infection rates and cervical cancer incidence among vaccinated populations. 
      • Vaccination programs aim to achieve herd immunity, thereby reducing overall transmission of HPV and protecting unvaccinated individuals.
    • Debate and Challenges: Debate surrounds the universal versus selective vaccination strategies, with considerations on cost-effectiveness, accessibility, and cultural acceptance.
      • Challenges include vaccine hesitancy, particularly in some regions, as well as affordability and logistical barriers to widespread vaccination coverage.

    Challenges Prevalent in Vaccine Manufacturing    

    • Complex Manufacturing Processes: Vaccine manufacturing involves complex biological processes and stringent quality control measures. 
      • Developing and scaling up production requires specialized facilities and skilled personnel, which can be costly and time-consuming to establish.
    • High Regulatory Standards: Vaccines are subject to rigorous regulatory scrutiny to ensure safety, efficacy, and consistency. 
      • Meeting regulatory requirements in multiple jurisdictions adds complexity and may delay the approval and market entry of new vaccines.
    • Supply Chain and Distribution: Maintaining a reliable supply chain for vaccine components and ensuring cold chain storage and distribution are critical challenges. 
      • This becomes even more pronounced in resource-constrained settings or during global health emergencies where demand surges.

    Its Impact on India                     

    • Delayed Access to Affordable Vaccines: India’s capability to produce vaccines at scale is hindered by stringent patent laws and complex regulatory requirements. 
      • This delays the availability of affordable vaccines domestically, impacting public health initiatives and access for vulnerable populations.
    • Economic and Health Implications: High costs associated with vaccine development and production limit affordability and accessibility, exacerbating healthcare inequalities. 
      • This affects India’s ability to address preventable diseases effectively, impacting public health outcomes and economic productivity.

    Unavailability of Competing Vaccines and Future Scope

    • Lack of Market Competition: Despite the expiration of earlier patents, there is a notable absence of competing HPV vaccines from domestic manufacturers in India. 
      • This limits options for consumers and healthcare providers, potentially leading to higher prices and reduced accessibility, particularly in the private market.
    • Potential for Future Development: Several Indian biotech companies had announced plans to develop HPV vaccines, indicating a future scope for competition and potentially lower prices. 
      • However, these initiatives have not materialized into market-ready products, highlighting challenges in vaccine development and commercialization in India’s regulatory and economic environment.

    Way forward: 

    • Promote Research and Development Incentives: Encourage and support Indian biotech companies through research grants, tax incentives, and streamlined regulatory pathways for HPV vaccine development.  
    • Enhance Public-Private Partnerships: Foster collaborations between government entities, academic institutions, and private-sector vaccine manufacturers to improve vaccine accessibility and affordability.

  • In an electric vehicle, what is Regenerative Braking?

    Why in the News?

    The Regenerative Braking device market is set to witness immense growth during the period 2024-2031 due to rise in prominence of e-vehicles.

    What is Regenerative Braking? 

    Regenerative braking is a technology used in electric and hybrid vehicles to capture and reuse energy that would otherwise be lost during braking.

    How Does It Work?

    1. Normal Braking: In a traditional vehicle, when you brake, the car’s kinetic energy (the energy it has while moving) is turned into heat and wasted.
    2. Regenerative Braking: 
    • In cars with regenerative braking, when you press the brake pedal, the electric motor runs in reverse.
    • This reverse action slows down the car, just like traditional brakes.
    • Instead of converting kinetic energy into heat, the motor converts it back into electrical energy.
    • This electrical energy is then stored in the vehicle’s battery for later use.
    1. Energy Conversion: This reversed motor converts the kinetic energy of the moving car into electrical energy.
    2. Energy Storage: The electrical energy produced is sent back to the car’s battery and stored for future use, such as powering the vehicle or running electrical systems.

    Significance:

    • Energy Efficiency: Saves energy by reusing it, reducing the need for frequent battery recharges.
    • Extended Range: Helps electric and hybrid vehicles travel further on a single charge.
    • Less Wear and Tear: Reduces wear on traditional brake components, leading to lower maintenance costs.

    Example: Imagine riding a bicycle down a hill. Normally, if you press the brakes, you slow down and the energy goes away as heat. But if you could somehow capture that energy and use it to help you pedal back up the hill, that would be similar to what regenerative braking does in a car.

     

    How does a Motor become a Generator?

    • A motor consists of a rotor (which rotates) and a stator (which is stationary). 
      • The stator contains magnets or electromagnets, while the rotor has current-carrying coils.
    • The Lorentz Force acts on the charged particles in the magnetic field, causing the rotor to spin.
    • In a generator, mechanical energy induces a current in the stator EVs can implement regenerative braking by switching the traction motor between these configurations.

    Downsides of Regenerative Braking

    • Regenerative braking alone often cannot bring a vehicle to a complete stop and must be supplemented by conventional braking systems.
    • Regenerative brakes may not prevent vehicles from backsliding downhill.
    • The efficiency of energy recovery drops as the vehicle’s speed decreases, though regenerative brakes are beneficial in stop-start traffic.

    Other Ways to Recover Energy

    • The design of a regenerative brake depends on the form of energy conversion. EVs convert mechanical energy into electrical energy stored in batteries or supercapacitors.
    • Flywheels can store mechanical energy by increasing angular momentum, useful in applications like Formula One racing and satellite navigation.
    • Kinetic energy can also be used to compress air, which can be useful for starting internal combustion engines.

  • Scientists find proof that Pain-Sensing Cells are either Male or Female

    Why in the News?

    Recent research has uncovered significant differences in how male and female nociceptors (pain receptors) are activated, paving the way for more precise, sex-specific pain management therapies. 

    About Pain and Differences in Perception:

    • The International Association for the Study of Pain defines it as “an unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage.”
    • Subjectivity: Pain perception is highly personal and varies among individuals.
    • Scientific Findings: Recent research by the University of Arizona Health Sciences demonstrated functional sexual dimorphism in nociceptors, the nerve cells responsible for perceiving pain

    Why do we perceive Pain?

    • Role of Nociceptors: Nociceptors are nerve cells with bare endings found throughout the body. They detect extreme pressure, temperature, and chemical signals, converting them into electrical signals sent to the brain via the spinal cord.
    • Activation Mechanism: Nociceptors in both men and women produce similar pain perceptions but are activated differently. 
      • Normally, they respond to high-intensity stimuli, but their activation threshold can decrease under certain conditions, causing low-intensity stimuli to trigger pain.

    Nociceptor Response Threshold

    • Gender Differences: Females generally have a lower nociceptor response threshold than males.
    • Peripheral Nociceptor Sensitisation: External factors can lower the pain threshold, causing nociceptors to react to stimuli they would normally ignore.

    The Old Vs New Study

    • Previous research showed that the hormone prolactin increases pain responses in female rodents, while the neurotransmitter orexin B sensitized male rodents to pain.
    • According to the New study, the Prolactin hormone increased nociceptor activation in female mice, while orexin-B had a similar effect in male mice. These findings were consistent across monkeys and humans.
    • Nociceptors in males and females can be differentially sensitized, leading to varying pain thresholds.

    Significance of this Pain Research

    • Sex-Specific Pain Treatment: Current pain management often overlooks the patient’s sex, despite differences in pain conditions between men and women.
      • Conditions like irritable bowel syndrome, migraines, and painful bladder syndrome are more common in women, while cluster headaches and gout are more frequent in men.

  • Hepatitis A vaccination will be cost-effective in Kerala: study

    Why in the News? 

    • Hepatitis A infection in Kerala is shifting from early childhood to adolescents and young adults due to better sanitation and hygiene practices.
      • The inclusion of hepatitis A vaccination into the mainstream immunization program for both one-year-old children and 15-year-old individuals in Kerala shows cost-effectiveness and success.

    Present State in Kerala and Overall India:

    • At the Regional level (Kerala): Kerala has been experiencing regular hepatitis A outbreaks, with the 2024 outbreak being particularly severe.
      • As of May 30, over 2,400 cases and 18 deaths have been reported, mainly in districts like Kozhikode, Malappuram, Thrissur, and Ernakulam.
    • At the National Level: Severity in Different Age Groups: Almost 50% of children aged 1-5 years in India were found to be susceptible to the hepatitis A virus.
      • However, the hepatitis A vaccine is currently only available for those who can afford it, and is not part of the national immunization program.

    About Hepatitis A infection:

    • The infection is usually mild or asymptomatic in children under six years but can be symptomatic and severe in older children, adolescents, and adults, occasionally leading to liver injury and fatalities.
    • India has recently launched its first indigenously developed hepatitis A vaccine, called Havisure:
      • Havisure was launched in January 2024 by Indian Immunologicals Limited (IIL), a subsidiary of the National Dairy Development Board.
      • IIL plans to manufacture up to 1 million doses of Havisure per year initially, focusing on the domestic market first.
    Types of Hepatitis Cause Vaccine
    Hepatitis A (HAV) Spread through ingestion of contaminated food or water. Hepatitis A vaccine (e.g., Havrix, Vaqta)
    Hepatitis B (HBV) Spread through contact with infectious body fluids (blood, semen, etc.) Hepatitis B vaccine (e.g., Engerix-B, Recombivax HB)
    Hepatitis C (HCV)  Spread primarily through blood-to-blood contact, often via injection drug use or unsafe medical procedures. No vaccine is available currently. Treatment focuses on antiviral medications
    Hepatitis D (HDV) Requires HBV as a co-infection to cause illness. No specific vaccine for HDV. Prevention relies on hepatitis B vaccination.
    Hepatitis E (HEV) Spread through ingestion of contaminated water, similar to HAV A vaccine is available in some regions (e.g., Hecolin in China), but not widely used. Prevention mainly involves improving sanitation and safe drinking water

    Benefits of Hepatitis A Vaccination in Kerala:

    • Lifelong Immunity: Vaccination provides lifelong immunity against the hepatitis A virus, protecting individuals from severe infections and health complications later in life.
    • Less Out-of-Pocket Expenditure: Studies have shown that vaccinating children aged one year and adolescents aged 15 years in Kerala using either live attenuated or inactivated vaccines is cost-effective.
      • Vaccination prevents future healthcare expenditures associated with treating hepatitis A infections.
    • Increase in Household savings: Implementing vaccination for adolescents could save Kerala ₹5,872 million to ₹10,553 million over five years, depending on the type of vaccine used.
    • Equal and Universal Accessibility: Due to the inclusion in the universal immunization program, these vaccines are accessible throughout all sections of society, whether rich or poor.

    Government Initiatives:

    • National Viral Hepatitis Control Program (NVHCP): The Ministry of Health and Family Welfare launched the NVHCP in July 2018 to prevent and control viral hepatitis in India.
      • The program aims to combat hepatitis and achieve country-wide elimination of hepatitis C by 2030, reduce morbidity and mortality associated with hepatitis B and C, and reduce the risk, morbidity, and mortality due to hepatitis A and E.
    • State-Level Initiatives: Some states like Punjab, Assam, Manipur, Tripura, and Haryana have started free or subsidized hepatitis C treatment programs.
      • Haryana launched its own Hepatitis Control Program in 2013 at PGIMS Rohtak, which was later expanded to all district civil hospitals in the state in 2017.

    What is the Prime challenge?

    • Achieving high vaccination coverage among adolescents, who are not covered under the universal immunization program, remains a challenge. Strategies such as school-based vaccination campaigns are proposed to enhance this kind of coverage.

    Conclusion:  Implement targeted vaccination campaigns in schools and communities to ensure high coverage among adolescents aged 15 years, who are not currently included in Kerala’s universal immunization program. This can be achieved through collaboration with schools, healthcare providers, and community organizations to raise awareness and facilitate easy access to vaccinations.

  • Primary Amoebic Meningoencephalitis (PAM) Cases in Kerala

    Why in the News?

    There have been four cases, including three deaths, of the rare, but fatal brain-eating primary amoebic Meningoencephalitis (PAM) in Kerala in the last two months.

    What is Primary Amoebic Meningoencephalitis (PAM)?

    • PAM is a rare brain infection caused by Naegleria fowleri, a free-living amoeba found in warm freshwater and soil worldwide.
      • An amoeba is a type of cell or unicellular organism with the ability to alter its shape, primarily by extending and retracting pseudopods.
      • Higher temperatures of up to 115°F (46°C) are conducive to its growth and it can survive for short periods in warm environments.
    • The amoeba enters the body through the nose, typically during activities like swimming, and travels to the brain, causing severe damage.
    • PAM is also non-communicable.
    • Symptoms: Headache, fever, nausea, vomiting, stiff neck, confusion, seizures, hallucinations, and coma.
      • According to the US Centers for Disease Control and Prevention (CDC), most people with PAM die within 1 to 18 days after symptoms begin. It usually leads to coma and death after 5 days.

    Diagnosis and Treatment:

    • Currently, there are no established effective treatments for PAM.
    • Diagnosis involves PCR tests of cerebrospinal fluid, though detection can be challenging due to the rarity of PAM.
    • Treatment follows CDC guidelines, including miltefosine, Azithromycin, and Amphotericin B, with miltefosine recently procured by the State Health Department from Germany.
      • Medical interventions typically involve a combination of drugs, including amphotericin B, azithromycin, fluconazole, rifampin, miltefosine, and dexamethasone.

  • What makes mosquitoes suck blood?

    Why in the News?

    A study published in the Proceedings of the National Academy of Sciences (PNAS) 1 has suggested that a pair of hormones work together to activate or suppress mosquitoes’ blood cravings.

    Mosquito Species and Behavior

    • There are around 3500 mosquito species globally, found on every continent except Antarctica.
    • Female mosquitoes consume blood to aid in egg development.
    • After feeding, female mosquitoes lose their appetite for blood until they lay their eggs.

    Research by Michael Strand and Team

    • Strand observed that levels of the mosquito gut hormone F (NPF) spiked when mosquitoes were seeking a host and dropped after feeding.
    • Their study analyzed mosquito enteroendocrine cells responsible for gut hormone production.
    • Hormonal Mechanisms:
      • NPF levels increased before blood meals and decreased six hours after feeding.
      • Another gut hormone, RYamide, was found to influence mosquitoes’ blood lust. As NPF levels decreased after a blood meal, RYamide levels increased, and vice versa.
      • The researchers concluded that NPF and RYamide work together to regulate mosquitoes’ attraction to humans and other hosts.

    Implications of the Study

    • Controlling the Deadliest Animal: Mosquitoes are the deadliest animal on the planet, acting as vectors for diseases such as malaria, dengue, West Nile virus, yellow fever, Zika, chikungunya, and lymphatic filariasis, which collectively kill more people than any other creature.
    • Pesticide Development: The discovery could lead to new pesticide targets for preventing mosquito reproduction and disease transmission.

    Note: Mosquitoes are responsible for over 1 million human deaths per year worldwide. They transmit deadly diseases like malaria, yellow fever, dengue, and Zika virus

    PYQ:

    [2023] ‘Wolbachia method’ is sometimes talked about with reference to which one of the following?

  • Universe had Spiral Galaxies 4 billion years sooner than expected: Study

    Why in the News?

    A new study has revealed more spiral galaxies in the universe’s youth than astronomers had previously expected.

    Universe’s Age and Galaxy Types

    • The universe is about 13.8 billion years old and hosts various kinds of galaxies, from spiral to elliptical.
    • Astronomers believed spiral galaxies formed about 6 billion years ago, but the new study calls this into question.
    • Younger galaxies tend to spiral, while older ones have a variety of shapes, making the study of older galaxies more challenging due to fainter light.

    Back2Basics: Spiral Galaxy

    • Spiral galaxies are a type of galaxy characterized by their spiral structure.
    • They are among the most common types of galaxies in the universe.
    • Our own Milky Way is a classic example of a spiral galaxy.

    Key Characteristics:

    • Central Bulge: A dense, spherical structure at the centre composed mainly of older stars.
    • Disk: Surrounding the bulge is a flat, rotating disk of stars, gas, and dust. The disk contains younger stars and spiral arms.
    • Spiral Arms: These are the defining features, winding outward from the central bulge. The arms are sites of active star formation and appear brighter due to the presence of young, hot stars.
    • Halo: A roughly spherical region surrounding the disk, containing old stars and globular clusters.

    Formation and Evolution:

    • Spiral galaxies are thought to form from the gravitational collapse of gas and dust in the early universe.
    • They maintain their structure through the rotation of the disk and the gravitational influence of the central bulge and halo.
    • Interactions and mergers with other galaxies can distort or destroy their spiral structure, potentially transforming them into elliptical galaxies.

    Formation of Galaxies

    • As the universe cooled from a dense plasma state, hot gas formed clumps that became galaxies.
    • These early galaxies had irregular shapes and lacked disks.
    • Spiral Formation Theory:
      • The traditional theory suggested that it took billions of years for hot, thick disks to become thinner and form spiral arms.
      • The new study suggests that cooling and spiral formation occur around the same cosmic time.

    How is this verified?

    • Astronomers observe star formation in real time but study galaxy evolution through “astronomical archaeology.”
      • Understanding the fraction of spiral galaxies helps astronomers trace the biography of galaxies.
      • Infrared and optical wavelengths are used to detect early galaxies, requiring powerful telescopes due to the faint light of older galaxies.
    • Study Methodology:
      • The University of Missouri team used the JWST to study 873 galaxies and identified at least 216 spiral galaxies, some dating to 1.5 billion years after the universe’s birth.
      • Each of the six authors classified the images as spiral or non-spiral, ensuring the result is free of human bias.

    Findings and Implications

    • The fraction of spiral galaxies increased from about 8% to 48% between 3 billion and 7 billion years after the Big Bang, higher than previously observed.
    • The study challenges existing models and suggests that galaxy formation theories need to be more complex.

  • Digital jurisprudence in India, in an AI era  

    Why in the news?

    Generative AI’s transformative potential challenges existing legal frameworks and judicial precedents, which are inadequate for effectively governing this rapidly-evolving technology designed for a pre-AI world.

    What is Generative AI?

    • Generative AI refers to artificial intelligence models that can generate original content like text, images, videos, and audio in response to prompts or requests.
    • These models learn patterns from large datasets and use that knowledge to create new content that resembles the training data.

    Persistent and Contentious Issues in Internet Governance

    Safe Harbour and Liability Fixation:

    • The Shreya Singhal judgment upholds Section 79 of the IT Act, granting intermediaries ‘safe harbour’ protection against liability for hosted content, contingent upon meeting due diligence requirements.
    • Challenges arise in applying these provisions to GAI tools, with debates on whether they should be classified as intermediaries, conduits, or active creators.
    • The Delhi High Court’s ruling in the Christian Louboutin Sas vs Nakul Bajaj and Ors (2018) case limited safe harbour protection to “passive” intermediaries.
    • The classification of GAI tools complicates the assignment of liability, especially in cases of user reposts.

    Generative AI and Legal Conflicts:

    • GAI outputs have led to legal conflicts, such as a lawsuit in the U.S. against OpenAI for defamation by ChatGPT.
    • Ambiguities in classifying GAI tools complicate legal decisions regarding liability.

    What Does the Indian Copyright Act 1957 Say?

    • Section 16 specifies that copyright protection is granted only under the provisions of the Act, with reluctance globally to extend protection to AI-generated works.
    • Critical questions include whether existing copyright laws should be revised for AI, the need for co-authorship with humans, and the responsibility for copyright infringement by AI tools.
    • The 161st Parliamentary Standing Committee Report highlights the inadequacy of the Copyright Act to facilitate AI authorship and ownership.
    • Current Indian law allows copyright owners to take legal action against infringement, but liability for AI-generated content remains unclear.

    Steps to Pursue (Way forward)

    • Learning by Doing: Implement a sandbox approach, granting temporary immunity from liability to GAI platforms for responsible development and data gathering to inform future regulations.
    • Data Rights and Responsibilities: Overhaul the data acquisition process for GAI training, ensuring legal compliance, proper licensing, and compensation for intellectual property used in training models. Potential solutions include revenue-sharing or licensing agreements with data owners.
    • Simplify the Licensing: Licensing data for GAI is complex due to the lack of a centralized licensing body for web data. The creation of centralized platforms, similar to stock photo websites, can simplify licensing, streamline access to data, and ensure data integrity against bias and discrimination.
    • Government and Judicial Approach to maximize the benefits of GAI: A comprehensive re-evaluation of existing digital jurisprudence is needed, requiring a holistic, government-wide approach and judicious interpretations by constitutional courts. The aim is to maximize the benefits of GAI while safeguarding individual rights and protecting against unwelcome harm.

  • On Improving Rural Mobile Connectivity 

    Why in the news? 

    On June 6, IEEE endorsed a wireless network structure aimed at providing economical broadband access in rural areas, formulated at IIT Bombay.

    About the latest Telecom Subscription Data        

    • Urban Tele-density: Urban tele-density in India is 127%, indicating that on average, each urban user has more than one mobile connection.
    • Rural Tele-density: Rural tele-density is significantly lower at 58%, meaning only about one in two rural residents has a mobile connection.
    • Urban-Rural Digital Divide: The data highlights a stark contrast between urban and rural areas, with urban areas having much higher mobile connectivity compared to rural regions, reflecting a significant digital divide.

    What are access and core networks?

    • Access Network (AN): The AN consists of base stations that provide wireless connectivity to mobile devices within a limited geographical area. It interfaces directly with mobile devices, facilitating communication and data transfer between devices and the wider network.
    • Core Network (CN): The CN comprises centralized network equipment that manages and directs data traffic between the access network, other networks (like the Internet), and service providers. It handles tasks such as routing, switching, and managing connectivity across the broader network infrastructure.

    What impedes rural connectivity?

    • Affordability: Lower income levels in rural areas make mobile services relatively expensive, limiting access for many rural residents.
    • Cost of Infrastructure: Installing and maintaining network infrastructure like fibre optics in remote rural areas is costly and may not be economically viable for service providers.
    • Low Population Density: Rural areas often have sparse populations spread over large geographic areas, making it less profitable for network operators to invest in infrastructure deployment.
    • Geographical Barriers: Difficult terrains and remote locations further complicate the installation of base stations and backhaul infrastructure necessary for robust network coverage.
    • Urban Bias in Technology: Most advancements in cellular networks, such as 5G, prioritize high data rates and low latency suitable for urban environments, neglecting the unique challenges of rural areas.
    • Limited Research: There has been insufficient research focused on developing cost-effective solutions that can efficiently cover large rural areas with adequate connectivity.

    What is the IEEE 2061-2024 standard? (Its working and architecture)   

    • IEEE 2061-2024 aims to establish a standardized wireless network architecture for affordable broadband access in rural areas.
    • It defines a heterogeneous Access Network (AN) comprising macro base stations (Macro-BS) and Wi-Fi base stations, integrated with a flexible Core Network (CN) bypass capability.

    Architecture:

    • Heterogeneous AN: Includes Macro-BS covering large areas with potentially lower data rates, complemented by Wi-Fi base stations deployed within villages for high-speed connectivity.
    • CN Bypass: Allows direct Internet access from the AN, bypassing the centralized Core Network for certain communications. This enhances efficiency and reduces latency, catering to stationary users common in rural settings.
    • Middle-Mile Connectivity: Utilizes multi-hop wireless networks (e.g., satellites, long-range Wi-Fi) to extend connectivity over long distances where optical fibre deployment is impractical or costly.

    What is a middle-mile network?

    • A middle-mile network refers to the infrastructure that connects core network hubs to local access points, spanning intermediate distances. It uses technologies like fibre optics, microwave links, or satellites to transport data between central and regional locations, facilitating efficient connectivity over longer distances without the need for direct local access networks.

    Conclude: To bridge the urban-rural digital divide in telecom, measures should focus on affordability through subsidized services, incentivizing infrastructure investment in rural areas, promoting research on rural-specific technologies, and ensuring equitable access to advanced wireless standards like IEEE 2061-2024.
