EVDO-WiFi Router

Model: WIFI-E100The EVDO-WiFi Router lets you create your own WiFi hotspot via 3G (EVDO) network at families, small offices, home offices (SOHO), vehicles, and anywhere.It is designed to provide a more cost-effective solution solution than deploying a new cablevision modem or ADSL modem. And its easy installation and maintenance can help 3G operators get fast return.You just need to insert an EVDO UIM card into the socket on the router's rear side, and then each WiFi-enabled device (such as a notebook, desktop PC, PDA, game console, cell phone, MP3 player) can connect to the internet when within the range of the router. The router can support...

Sharing a Broadband Internet Connection

Raymond J. Smith, WiFi Home Networking, McGrawHill CompaniesIf you have an existing network, and you’ve just installed a broadband link to the Internet, you can make that link work for all your existing computers, whether the link is via satellite, cable modem, or Telco digital subscriber line (DSL). You should check with your Internet service provider (ISP) before you do so, however, because their policies vary. Most don’t mind customers sharing access among their own PCs. Most do mind customers sharing with friends or neighbors. Some don’t care, and some flatly forbid it and actively seek out users who share in any way. As mentioned in the previous chapter, you should base your choice of ISP on this policy question as well as on other factors.The simplest way to share an Internet line is...

IEEE Wireless Standards

Raymond J. Smith, WiFi Home Networking, McGrawHill CompaniesThe first attempt at a wireless standard was the HomeRF protocol, which did not catch on because of its slow (1.6 Mbps) speed. It was replaced by the802.11 standard, which ran at 1 or 2 Mbps. Because of its limited speed, it is also history. In 1999, the IEEE added the “a” and “b” refinements.Products conforming to the 802.11a standard operate at speeds of up to 54 Mbps on a very short-wave frequency of 5 billion cycles per second, or5 gigahertz, abbreviated GHz. Its speed advantage is offset by its shorter range, which is typically 50 to 200 meters. Unlike the more popular b standard,it uses a modulation scheme with the hefty name of Orthogonal Frequency Division Multiplexing (OFDM) that makes possible data speeds ashigh as 54 Mbps...
