What is Fiber Broadband (FTTH) and Why Is It Better Than Copper Cable Internet? Fiber broadband, commonly called FTTH — Fiber to the Home , is a broadband technology where optical fiber cable is extended directly up to the customer’s home. Instead of sending internet signals through electrical pulses over copper wire, FTTH sends data as pulses of light through glass or plastic fiber strands. This makes FTTH fundamentally different from older copper-based broadband such as DSL, ADSL, VDSL, and coaxial cable networks. Globally, telecom networks are moving from copper to fiber because modern homes now use far more bandwidth than before: smart TVs, online classes, video meetings, cloud backups, gaming, security cameras, OTT platforms, AI tools, and smart-home devices all need stable, high-capacity internet. According to OECD data, fiber accounted for 44.6% of all fixed broadband subscriptions in OECD countries as of June 2024 , up from 41% the previous year. OECD also describes fiber as a ...

How Mobile Towers Work: The Science Behind Your Signal Ever wondered why you have "full bars" in the balcony but the call drops the moment you move to the kitchen? Understanding how mobile towers function in your neighborhood can help you troubleshoot your connection and understand the tech we use every day. 1. Your Phone is a Two-Way Radio Every time you make a call or send a WhatsApp message, your phone converts that data into radio waves . The Transmission: These waves travel through the air to the antennas on a mobile tower. The Processing: The tower is connected to a "Base Station" at the ground level. This station sends your signal through high-speed fiber-optic cables to the core network. The Connection: The network finds the person you are calling and sends the signal to the tower closest to them, which then beams it to their phone. 2. Why "Cells" Matter Mobile networks are called "cellular networks" because they divide land into smal...

Have you ever wondered how much of your phone’s invisible signals your body absorbs ? This is a fair question that makes many of us pause. The clear, science-backed answer comes down to one easy-to-understand number called SAR , and the data shows you can relax while still using your phone wisely. What SAR Actually Measures SAR stands for Specific Absorption Rate . Imagine your body as a sponge and the radio waves from your phone as a gentle sprinkle of water. SAR tells scientists exactly how much of that “water” (energy) gets absorbed into one kilogram of body tissue, measured in watts per kilogram (W/kg). Phones are tested in laboratories using special models that copy human heads and bodies. Testers run the phone at full power, right against the “ear” or “body,” and measure the peak absorption. It is like checking the temperature of a hot drink at its hottest sip to ensure that it never burns you. The Numbers That Keep You Protected In the United States and Canada, the legal ...
