Question
How did the standards for wireless LANs develop?
Expert Solution
Step 1
Assessment of network protocols:
Since the introduction of IEEE 802.11, several IEEE wireless LAN protocols have emerged.
IEEE 802.11b, which was approved in 1999, uses 2.4-GHz signals to transport data at a maximum speed of 11 Mbps (because of noise, the real rate is around half the potential rate).
