Comparing different Wireless Signals

Wireless Signals Comparison:
Wireless network technology covers a wide range of different topics such as uses, abilities, types, and ranges. There is wireless phone technology, satellite communications, short range wireless, and wireless LAN technology. They all work in the same field but provide specific types of service that may sometimes overlap. We will look at some of the capabilities of these four types of wireless technologies, compare them to each other while providing examples of how to use each type in a WAN service and network.
The most common signal form would have to be mobile cellular communication; which has been around for many years. In the beginning they have very limited reliability, bandwidth, and usage; but throughout the years cellular communications has provided or can provide virtually the same service as other WAN technologies. Bandwidth and reliability have become a common method for accessing the Internet as well as having the use of mobile devices, which shell include such things as laptops, desktops, and cell phones. High Speed Downlink Access or 3G (HSPDA), WiMax technologies, and (HSPA) can deliver a bandwidth starting at about 200 Kbps and will go up at least 100 Mbps for highly mobile IMT (International Mobile telecommunications) advanced 4G solutions and dynamic channel allocation to deliver higher bandwidth (Will Knight, 2005)
IEEE 802.11b/g standards have been used widely for LAN based networks for years, providing 11 Mbps (for 802.11b) and 54 Mbps (for 802.11g) and WAN applications. The 802.11b standard uses CCK or Complimentary Code Keying as its modulation technique, which enables it to boost bandwidth from the original 1 Mbps that was supported by the original 802.11 standard to 11 Mbps. The 802.16 standard is primarily used to provide mobile broadband access under the commercial name of WiMax (which stands for...
