Nokia C3: The IEEE 802.11r formalized protocol

The Institute of Electrical and Electronics Engineers (IEEE) has formally propose the IEEE 802.11r protocol, as a new standard for wireless telephony over Internet (VOIP).

Currently, when moving a call on VOIP, within a company for example, we use the standard IEEE 802.11. But this standard has been established to facilitate access to a connection point. On the move, it therefore systematically seeks a new network to connect. It is precisely this time of reconnection, which is pointed by the IEEE as it takes about 100 milliseconds to be detected and several seconds to re-establish a secure connection. To overcome this problem, several WiFi network administrators have had to lower the security level of connection dedicating VOIP traffic on an access point separately.

For four years the IEEE board therefore on the IEEE 802.11r protocol which would accelerate the "roaming", this change of connection when moving from one network to another. The latter should not exceed 50 milliseconds and thus enable continuity of Appeal on the change from hot-spots. Last June, the consortium Wi-Fi Alliance has issued a new protocol that the certificate "Wi-Fi Certified Personal Voice." Large companies such as Cisco and Meru have already reformed their infrastructure around the IEEE 802.11r but several companies expect
