| 802.11b/g | A common and cost-effective data radio technology is 802.11. 802.11b specifies radio transceivers that operate at up to 11Mbps. 802.11g operates at up to 54Mbps. Both B and G standards have several fall-back speeds and attempt to initiate or maintain the highest bit rate conditions allow. There is significant overhead in the wireless protocol. Real-world best-case data transfer performance is approx. 5Mbps for B and 20Mbps for G. Distance, radio interference, objects between radio endpoints, and the number of radios participating in a cell are all factors affecting actual performance.
