Wireless Internet Basics

Jul 11, 2008

Wireless Internet refers to Internet access options where the “last mile” connectivity is wireless in nature. The advantages of having a wireless last mile are mobility and greater ease of deployment. The disadvantages are lower security and performance.

Fixed Wireless Internet works via a dish antenna receiving signals from an elevated line of sight tower within 50 km. Or via Satellite. Mobile Wireless Internet works via Bluetooth, WiFi, Mesh networks, WiMAX, GPRS, 1xRTT, EDGE, EV-DO and HSDPA.

A very approximate way of describing the mobile options would be to say that access via Bluetooth is like a television remote, which works only within a room. Access via WiFi is like a cordless phone, which works only within a building. Access via mesh networks or WiMAX is like a mobile phone without roaming, which works only within a city. While access via EDGE, 1xRTT, EV-DO or HSDPA is like a mobile phone with roaming, which works across the country or at least wherever the cellular signal exists.
