Wi-Fi or IEEE 802.11 The alternative to the 3G networks is Wi-Fi (wireless fidelity) local area networks. There are a number of wireless networking standards including the IEEE 802.11 family. To aid consumers, the Wi-Fi Alliance (WECA) certifies appliances to be interoperable regardless of the manufacturer as long as they are using the same version of the IEEE standards. There are three main standards: 802.11a, b, and g. 38 The Technology of Video and Audio Streaming Table 2.8 IEEE 802.11 Standards Data rate Carrier frequency band No. of channels IEEE802.11a 54 Mbit/s 5 GHz 8 IEEE802.11b 11 Mbit/s 2.4 GHz 14 IEEE802.11g 54 Mbit/s 2.4 GHz 14 The range of the wireless networks is short, up to a maximum of 100 meters, but that is more than adequate to flood your local coffee bar with wireless connectivity to the Internet. The 2.4-GHz band can be congested, as it is shared with a number of cordless appliances, phones, and Bluetooth devices, plus microwave ovens. Always-on and client security The domestic user of the Internet with a cable modem or DSL connection that stays permanently connected to the network is at a higher risk of attack by hackers than the user of a dial-up circuit who is connected only for short periods of time. As a consequence the user with permanent connection will have to take greater security precautions with software and/or hardware firewalls. The wireless networks come with integral encryption to make snooping more difficult. Summary It is a demonstration of the flexibility of the OSI layer model of network communications that a system developed for the transfer of text and data files has been stretched to carry real-time multimedia. That is not to say everything is dandy. Anyone who has watched streams will know it is not always an enriching experience. Stalling video and distorted audio do not make for good viewing.
