The IEEE 802.15.4 standard for Low-Rate Wireless Personal Area Networks (LRWPANs) supports a maximum over-the-air data rate of 250 kbps for the 2400-MHz band. In practice, the effective data rate is somewhat lower due to the protocol built into the frame structure. Various mechanisms are also employed to ensure robust data transmission for wireless mesh based networks. These include channel access algorithms, data verification and frame acknowledgement. The data frame structure and associated protocol overhead are described, and used to determine the maximum data payload and packet transmission time. The channel access and frame acknowledge times are also calculated. Support 250+node wireless mesh networks.
