Wireless Broadband Internet
Of these Wi-Fi (short for wireless fidelity)technology has achieved wide ranging acceptance and is found in almost all laptops sold today. The areas where Wi-Fi coverage is found are called 'hot spots', because the Wi-Fi broadcast range is usually only up to 150 feet from an antenna. In addition, the technology is used to install wireless networks at home to share a high-speed Internet connection between multiple PCs from various rooms. There are tens of thousands of wireless broadband internet hot spots available. For example, jiwire.com lists over 67,000 hot spot locations globally, with over 18,000 of them in the U.S.). The speeds you can achieve over a Wi-Fi connection depend on the type of Wi-Fi technology used. 802.11g, which is the current fastest Wi-Fi standard, has theoretical maximum rates of 54mbps. Other Wi-Fi standards include 802.11b and 802.11a. Wireless Broadband Internet - Cell Phone TechnologiesThe plans will be less about making voice calls than they are about transferring images, e-mail, documents and live picture. Some of the data transfer speeds with the new and upcoming wireless broadband internet service plans will be up to 2.4 MB per second, making transferring live picture via a cell phone connection a child's play. These new service plans are called 3G services. The first generation (1G) is the analog network that is still operational and 2G is the since 1994 operational digital network. Today, you can try cell phone technologies developed around a technology called CDMA2000 1xRTT, which has theoretical data transfer speeds of around 144 kbps. Companies that offer CDMA2000 1xRTT technology are Sprint, Verizon, U.S. Cellular and ALLTEL. Not all these companies have commercially available plans, but they already have the technology. There is also GPRS/EDGE technology widely available from, for example, Cingular, which promises data transfer rates of 384 kbps.
