What Is IEEE 802.11a?

If you're looking for a fast, reliable standard with a lot of bandwidth, look no further than IEEE 802.11a-1999! An amendment to the 802.11 standards for wireless LANs, IEEE 802.11a is one of the most common Wi-Fi specifications. It operates at 5 GHz radio frequencies and can deliver up to 54 Mbps of throughput, for example. The 802.11a specification uses the same base protocol as the original 802.11 standards but employs orthogonal frequency-division multiplexing (OFDM). OFDM is used instead of plain old FM because it allows for better channel utilization by splitting one carrier into multiple subcarriers—this means less interference with other signals on the same channel and better data transfer speeds. With this technology, you can have your cake and eat it too: faster Internet connections without dealing with dead zones or other technical difficulties! IEEE 802.11a was the first wireless standard to be deployed in homes and businesses. Its predecessors were 802.11b and 802.11g, which were used in the early 2000s to connect computers to the internet at speeds of 54 Mbps or less. 802.11a was capable of much greater speeds: up to 54 Mbps for outdoor use and up to 300 Mbps for indoor use (as opposed to 54 Mbps and 72 Mbps). It didn't catch on because it was more expensive than its predecessors. However, it's not dead yet—some places still use it today. For example, suppose you're looking for high-speed wireless gaming or streaming video networks. It would be best to consider 802.11a because it offers better quality than its competing standards (802.11b and g). Some people still get annoyed when they see their devices connected through either of those standards because they know they could be getting faster if they chose an alternative instead!
