    As Kenya continues to expand its public Wi-Fi initiatives and digital services, these new licensing rules represent a critical step towards ensuring a secure online environment for all users.

  • Li-Fi vs. Wi-Fi: Exploring the next big thing in connectivity

    Li-Fi vs. Wi-Fi: Exploring the next big thing in connectivity

    What’s Li-Fi? Light Fidelity (Li-Fi) is the latest wireless lighting-communication technology that uses light signals instead of radio frequencies like Wi-Fi. Li-Fi, the next generation of Internet technology, can revolutionise the world by enabling incredible connection speeds, security, and stability in specific settings.

    Professor Viktor Grigoriev’s research group at the Ecole Polytechnique Fédérale de Lausanne in Switzerland began marketing wireless communication technology called Li-Fi in 2011. Before that, it was called ‘Visible Light Communications’. Li-Fi means Wireless Lightwave Communications and operates like this. This article explains Li-Fi, its advantages over Wi-Fi, and its potential to change our digital experience.

    What is the difference between Li-Fi and Wi-Fi? 

    LED light bulbs enable Li-Fi light connections. Some bulbs switch data in light waves at a frequency the naked eye cannot perceive. A smartphone or laptop photodetector converts light impulses into internet data. Unlike Wi-Fi, LiFi runs in the visible light frequency band, benefiting from the light spectrum range and transferring data faster.

    Li-Fi’s main feature is its ability to provide 100 times faster speeds than Wi-Fi. In ideal conditions, Li-Fi can transfer data at 1.25 to 224 gigabits per second, a pace conventional wireless fidelity technology cannot match. Thus, Li-Fi is excellent for streaming HD videos or downloading files in seconds. 

    What makes Li-Fi faster than Wi-Fi? 

    Li-Fi has several advantages over traditional Wi-Fi connections, as listed below. First and foremost, it is speed. As noted, Li-Fi can offer higher data transfer rates than Wi-Fi today. This is especially true in areas where real-time transfer of bulky data is paramount, such as hospitals or military operations. 

    The other significant benefit is security or the lack thereof, as it refers to information. Li-Fi, on the other hand, uses light, and therefore, a light beam cannot go through solid structures such as walls; hence, the signal is localised. This makes Li-Fi inherently more secure against unauthorised access since anyone wishing to tap into the signal must have a direct view of the source light. However, Wi-Fi is known to be vulnerable to hacking compared to Bluetooth, as it operates through radio waves capable of passing through walls, among other barriers. 

    Li-Fi also lacks interference, and it has reduced interference cases. Another disadvantage of using Wi-Fi is that radio waves utilised by this technology may be interfered with by other electrical equipment, thus deteriorating connection strength. However, Li-Fi does not interfere with radio waves, thus making it more reliable in environments with several electronic devices.

    Li-Fi vs. Wi-Fi: A Comparative Analysis 

    Li-Fi’s unique properties allow many uses. Li-Fi might be a safe, high-speed data communication option in hospitals where radio waves can interfere with medical equipment. Li-Fi might improve corporate security by restricting critical data flows to certain areas. 

    On the other hand, Wi-Fi has become essential in modern life, enabling seamless internet access in homes, offices, and public spaces. It powers smart devices in the IoT ecosystem, supports remote learning and telemedicine, and is vital for business communication and cloud computing. Additionally, Wi-Fi fuels entertainment through streaming, online gaming, and social media, making it indispensable in daily activities.

    Li-Fi also affects smart homes. Li-Fi in residential lighting systems might provide a seamless network where every light bulb is an internet router. This might improve energy efficiency and living connectivity.

    Li-Fi can also relieve radio frequency spectrum congestion in heavily populated places by providing an alternate communication method. This might boost network performance and eliminate lost connections and poor speeds.

    Wireless communication has advanced dramatically with Li-Fi. With its ultra-fast data transmission speeds, increased security, and interference resistance, Li-Fi might revolutionise internet connectivity. Even if technology is still developing, Li-Fi has the potential to transform healthcare, smart homes, and other sectors. As research and development continue, Li-Fi may become the norm for secure, high-speed wireless communication. 

  • The Impact of Cell phones’ Electromagnetic Fields (EMF), Wi-Fi on health

    The Impact of Cell phones’ Electromagnetic Fields (EMF), Wi-Fi on health

    In recent years, there has been growing concern over the potential health effects of non-native electromagnetic fields (EMF) generated by cell phones and Wi-Fi devices. Numerous studies have conclusively shown that these EMFs can have a significant impact on various bodily systems and functions. In this comprehensive exploration, we delve into the implications of EMFs, the risks associated with charging devices close to the head, and crucial precautions to protect your health and safety.

    One often overlooked aspect of charging our beloved smartphones is the heat generated during the process. Experts warn that this heat can lead to a potentially hazardous condition known as “thermal runaway” in the battery. Thermal runaway occurs when the heat produced during charging cannot escape, causing the charger and battery to heat up excessively.

    To put it simply, charging your phone can turn into a dangerous affair if not handled with care. This issue becomes especially critical when we consider where many people charge their phones—right next to their heads while they sleep. Your bed or pillow might seem like a convenient spot to plug in your device, but it poses a serious fire risk. Batteries heat up during charging, and if any mishap occurs, the consequences can be catastrophic. To reduce the risk of fire accidents, it’s advisable to place your charging phone on a non-flammable surface, such as a saucer, while you sleep.

    EMF and Its Effects on the Central Nervous System

    Oxidative Stress, Cell Death, and Brain Health

    The impact of EMF on our bodies goes beyond the risk of thermal runaway and fires. Research has shown that radio frequency EMF, which is emitted by cell phones and Wi-Fi devices, can induce oxidative stress, disrupt the central nervous system, and even lead to cell death. These effects are particularly concerning when devices are used in close proximity to the head.

    The proximity issue raises concerns about the safety of using smartphones close to the head, especially during activities like making calls or using wireless headphones. Some studies have suggested a link between EMF exposure and certain health conditions, including brain and central nervous system cancers. While these findings are still debated in the scientific community, they underscore the importance of taking precautions when using devices that emit EMFs near the head.

    Protecting Your Health and Minimizing EMF Exposure

    Given the potential risks associated with EMFs and the proximity to the head, it’s essential to adopt measures that minimize exposure and ensure your safety:

    Use an Ethernet-Connected Adaptor: When possible, opt for a wired connection instead of Wi-Fi to reduce EMF exposure in your home or workspace.

    Consider a Power Bank: Instead of charging your phone next to your head, use a power bank to charge your device in a safer location.

    Activate Airplane Mode: Before bedtime, switch your phone to airplane mode to disable wireless communication functions, reducing EMF emissions while you sleep.

    Keep Devices Out of the Bedroom: As a general practice, consider leaving your phone outside the bedroom to create an EMF-free sleeping environment.

    It’s crucial to stay informed about the potential risks associated with EMFs and take steps to protect your health and well-being. While the debate on the long-term effects of EMFs continues, adopting these precautions can help you minimize potential risks and ensure a safer and healthier lifestyle.

    What is Broadband?

    In telecommunications, broadband is wide bandwidth data transmission which transports multiple signals at a wide range of frequencies and Internet traffic types, which enables messages to be sent simultaneously and used in fast internet connections.

    Broadband includes several high-speed transmission technologies such as Digital Subscriber Line (DSL), Cable Modem, Fiber, Wireless, Satellite, and Broadband over Powerlines (BPL). The broadband technology a subscriber chooses will depend on several factors. These may include whether he is located in an urban or rural area, how broadband Internet access is packaged with other services (such as voice telephone and home entertainment), price and availability.

    Broadband Usage in Nigeria

    Statistics from the Nigerian Communications Commission (NCC) showed that some 25 million Nigerians in some 114 communities, otherwise known as access gaps, have no access to essential telecommunication services in the country.

    The data also shows that, as of January 2022, 79.4 million Nigerians have broadband access, representing 41.61 per cent. The penetration dropped in February to 40.9 per cent, with 78 million users.

    It however rose in March to 42.91 per cent and 80.6 million users. It increased in April with 81.9 million Nigerians having access and getting 42.79 per cent. By May, the current data customers have increased to 83.3 million with 43.7 per cent market reach.

    The digital divide which refers to the gap between people that have access to modern Information and Communications Technology (ICT) and those that do not have access or have restricted access is being influenced by the disparity in access levels in homes in Nigeria. Those in rural communities have fewer access opportunities.

    Bridging the Gap

    Through the National Broadband Plan 2020 to 2025, NCC set a target of 70% penetration and 90% population reach, and the recent increase to 44.5% shows that there are results for the Commission’s effort.

    The World Bank has found that in low- and middle-income countries, every 10 percentage point increase in broadband penetration accelerates economic growth by 1.38 percentage points. This is more than in high-income countries and more than for other telecommunications services.

    The World Bank challenged sub-Saharan Africa, focusing on Nigeria, to ensure it leads the region in connecting about 1.1 billion online by 2030 and bridge the connectivity gap. To get this done, the World Bank estimated that about $100 billion or close to $9 billion would be required yearly. The deployment of nearly 250,000 new 4G base stations and at least 250,000 kilometres of fibre across the region is required to achieve this remarkable feat.

    It stressed that connecting the unconnected would also require rolling out innovative and alternative solutions (Wi-Fi and satellites) to reach the nearly 100 million people that live in remote, rural areas, currently out of reach of traditional mobile networks.

    According to the World Bank, for the most part, achieving universal access to broadband connectivity is an infrastructure challenge, with nearly 80 per cent of all required investments directly tied to the need to roll out and maintain broadband networks.

    It noted that investing in good quality, affordable and reliable infrastructure won’t be enough as an additional $18 billion will be needed to develop a digital ecosystem, which means investing in basic digital skills and local content to support development opportunities.
