3. A TECHNOLOGY THAT CAN DO WONDERS

9. 802.20 MobileFi or Mobile Broadband Wireless Access: It established in December 2002 that originally planned to define mobile broadband wireless access (MBWA), with 802.16 (WiMAX) addressing fixed-location access. 802.16e (Mobile WiMAX) is now an alternative service. In June 2006 the IEEE suspended 802.20 activities temporarily because of various irregularities in the proceedings. 802.21: The IEEE 802.21 working group, which began in early 2004, is developing standards and protocols that support mobile communication handover (passing control from one base station to another) and interoperability between similar and dissimilar networks. This work includes 802-type networks such as Wi-Fi (802.11), Bluetooth (802.15.1), and WiMAX (802.16) as well as non-802 networks such as those for 2.5G/3G mobile cellular communications. The standard is expected to enable mobile devices to determine when to switch from 802.11 to cdma2000, for example, based on their current radio environment. One goal is to allow VoIP and other office applications to move seamlessly to the field and operate there equally well. No timeframe is established yet for completing this standard. Global Area Network: The final step in the area network scale is the global area network (GAN). The proposal for GAN is IEEE 802.20. A true GAN would work a lot like today's cell phone networks, with users able to travel across the country and still have access to the network the whole time. This network would have enough bandwidth to offer Internet access comparable to cable modem service, but it would be accessible to mobile, always-connected devices like laptops or next-generation cell phones. … IEEE standards

10. SUMMARY OF IEEE SPECIFICATIONS No native support for IP, so it does not support TCP/IP and wireless LAN applications well. Not originally created to support wireless LANs. Best suited for connecting PDAs, cell phones and PCs in short intervals. FHSS Up to 2Mbps in the 2.45GHz band Bluetooth Commonly referred to as WiMAX or less commonly as WirelessMAN or the Air Interface Standard, IEEE 802.16 is a specification for fixed broadband wireless metropolitan access networks (MANs) OFDM Added support for the 2 to 11 GHz range. IEEE 802.16a (WiMAX) Commonly referred to as WiMAX or less commonly as WirelessMAN or the Air Interface Standard, IEEE 802.16 is a specification for fixed broadband wireless metropolitan access networks (MANs) OFDM Specifies WiMAX in the 10 to 66 GHz range IEEE 802.16 (WiMAX) "Wi-Fi Certified." May replace 802.11b. Improved security enhancements over 802.11. Compatible with 802.11b. 14 channels available in the 2.4GHz band (only 11 of which can be used in the U.S. due to FCC regulations) with only three non-overlapping channels. OFDM above 20Mbps, DSSS with CCK below 20Mbps Up to 54Mbps in the 2.4GHz band IEEE 802.11g Wi-Fi "Wi-Fi Certified." Not interoperable with 802.11a. Requires fewer access points than 802.11a for coverage of large areas. Offers high-speed access to data at up to 300 feet from base station. 14 channels available in the 2.4GHz band (only 11 of which can be used in the U.S. due to FCC regulations) DSSS with CCK Up to 11Mbps in the 2.4GHz band IEEE 802.11b Wi-Fi "Wi-Fi Certified." Eight available channels. Less potential for RF interference than 802.11b and 802.11g. Better than 802.11b at supporting multimedia voice, video and large-image applications in densely populated user environments. OFDM Up to 54Mbps in the 5GHz band IEEE 802.11a Wi-Fi This specification has been extended into 802.11b. FHSS or DSSS Up to 2Mbps in the 2.4GHz band IEEE 802.11 Pros/Cons & More Info Modulation Scheme Data Rate Standard
