Although 5 GHz was less congested and had greater bandwidth which gave better performance for wireless LANs, the additional cost for chips at 5 GHz was still a major factor. The lower cost of chips using 2.4GHz combined with the higher speed meant that for many years it became the dominant Wi-Fi technology. In doing this it further established wireless technology as a viable standard for data communications using wireless LANs at home and in the office. IEEE 802.11g had the advantage that it could support the high data speeds using 2.4 GHz which had previously only attainable using 802.11a within the 5GHz ISM band. It built on the performance and played a pivotal role in further establishing Wi-Fi as a major wireless communications standard. IEEE 802.11g was one of the main Wi-Fi standards to follow on from 802.11a and 802.11b.
