WIreless Connectivity and Services

Cell Phone Tower	The use of high speed wireless is available for laptops, cell phones and other hand held mobile devices at speeds that used to be reserved for DSL and cable. WiMax and EV-DO are newer forms of technology that are turning the wireless Internet service providers into the main access ports for mobile connections. The ISPs today can service all your wireless needs for both in your office and at home. Plus there are devices for your mobile connections as well. Dial up can run at 56kbps but the introduction of wireless can make your connection run at 384kbps or up to 2.0Mbps without a wire. The speed of connecting with a WiMax device is around 7Mbps which can make your laptop run as good as your office equipment. The WiFi connection makes this speed possible. There are devices to attach to your USB port that connect to WiMax or EV-DO.
These devices, when running from your USB port allow you to connect almost anywhere without a wireless router. Cell phones and laptops can now access the Internet at these speeds and have become great mobile devices to access any connection via the Internet. The speed will make your laptop seem to work as well as your office or home PC. Looking for a hot spot to connect to is no longer an issue with cell phones and laptops. The equipment you use to access these wireless devices is not the same that you use in an office since no Ethernet cable or NIC card is needed, only a WiMax or EV-DO device plugged into your USB port. Most of today's laptops already have a wireless device installed in them from the manufacturer. The wireless card in the laptop needs an unblocked wireless port on a router to function. Using a WiMax USB device can give you access outside of the confines of a router. The device can connect your laptop, as does your cell phone, to towers and satellites that will allow access to wireless Internet service providers and the Internet. The WISPs provide access points using the tower that they use with cell phones and other devices. The WiMax device in the USB port on your laptop can pickup a connection via the WISPs towers or satellites making it very mobile. Using a national company can provide the coverage needed when traveling all over a state, country or the world. You will eventually lose the connection from local companies since their coverage area is much smaller and localized. Check your local newspaper or telephone book to find the best WISPs (Wireless Internet Service Providers). Also check with the top cell phone providers since they almost all have devices to accommodate your needs. --------WiMAX is a wireless digital communications system, also known as IEEE 802.16, that is intended for wireless "metropolitan area networks". WiMAX can provide broadband wireless access (BWA) up to 30 miles (50 km) for fixed stations, and 3 - 10 miles (5 - 15 km) for mobile stations. In contrast, the WiFi/802.11 wireless local area network standard is limited in most cases to only 100 - 300 feet (30 - 100m). --------EVDO, also known as EV-DO, 1xEvDO and 1xEV-DO, is a standard for high speed wireless broadband. The acronym is short for "Evolution, Data Only" or "Evolution, Data Optimized". It is one of two major Third Generation, or 3G, wireless standards. The competing standard is known as W-CDMA --------3G is designed to provide voice and high-speed mobile data using the cellular approach already proven to work in mobile phone networks. The biggest obstacle to implementing high speed wireless networks is the lack of bandwidth, or range of usable frequencies. Just as only so many radio stations can be squeezed onto the FM dial, only so much data can be transmitted across the available bandwidth. EVDO is an advanced CDMA technology developed by Qualcomm to deal with this limitation.                ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~          Read more - Personal Security Threats to Young Cell Phone Users
