Thus 802.11g offers an attractive data rate for the majority of users. The 802.11g standard is backwards compatible with the 802.11b standard. Today 802.11g is still the most commonly deployed standard. 802.11a. Ratification of 802.11a took place in 1999. The 802.11a standard uses the 5 GHz spectrum and has a maximum theoretical 54 Mbps data rate. 802.11a was one of the first Wi-Fi communication standards created in the IEEE 802.11 standards family. It is often mentioned in relation to other standards that came later, such as 802.11b/g/n and 802.11ac. Knowing that they're different is useful when buying a new router or connecting new devices to an old network that might not support new tech.

Transmitter and Receiver hardware Zedboard (Xilinx Zynq®-7000) + AD9361 (Analog Device-FMCOMMS3) Software needed Matlab R2016a. 4.2.1 The device Atheros was the first company to release a complete 802.11a solution, and therefore most existing products are based on it. Proxim was the first company releasing products based on the Atheros chipset, but other familiar names such as Linksys, D-Link and SMC did follow quickly.. Most vendor offer a CardBus card (32 bits Pcmcia) and Access Points, and a few offer PCI solutions. Networks using 802.11a operate at radio frequency of 5GHz or 3.7GHz and a bandwidth of 20MHz. The specification uses a modulation scheme known as orthogonal frequency-division multiplexing (OFDM) that is especially well suited to use in office settings. In 802.11a, data speeds as high as 54 Mbps are possible.

Today, 802.11a is considered a legacy protocol. It may seem odd that 802.11b is "Wi-Fi 1" instead of 802.11a. The reason for this is that 802.11b radios were cheaper and grew in adoption quicker, even though the standards were released in the same year. 802.11a mostly saw adoption with businesses, while 802.11b saw more widespread general use. IEEE 802.11a adalah sebuah teknologi jaringan nirkabel yang merupakan pengembangan lebih lanjut dari standar IEEE 802.11 yang asli, tetapi bekerja pada bandwidth 5.8 GHz dengan kecepatan maksimum hingga 54 Mb/s. Metode transmisi yang digunakan adalah Orthogonal Frequency Division Multiplexing (OFDM), yang mengizinkan pentransmisian data secara paralel di dalam sub-frekuensi.
