Avaya, Broadcom Head Group for 2.5G, 5G Ethernet Networking
Brocade, Aruba and Freescale also are part of the MGBASE-T Alliance, which supports an IEEE effort to increase speeds in enterprise WiFi networks.Broadcom, Brocade, Aruba Networks and Avaya are among the founders of a new industry consortium that wants to accelerate the adoption of 2.5 and 5 Gigabit Ethernet speeds in enterprise-level wireless products to help speed up the movement of traffic over wireless networks. The bulk of wireless networks in enterprises are based on 1GbE. At a time when workers increasingly are carrying more mobile devices and relying more on video-based content, and 802.11ac WiFi is hitting the market, 1GbE networks are having a difficult time keeping up with growing tide of wireless traffic. The IEEE is working to develop 2.5G and 5G Ethernet standards for access points and other systems that rely on unshielded twisted pair (UTP) cabling. The goal is to meet the demand for Ethernet speeds that fall between 1G and 10G. The new MGBASE-T Alliance—which also includes Freescale, Delta Electronics, Delta Networks, Pulse Networks and Ruijie Networks—is throwing its support behind the efforts of the IEEE, which has formed a study group to look at 2.5G and 5G. There already are 802.11ac products on the market—part of Wave 1 for the standard, according to Simon Assouad, associate director of product marketing for Broadcom's Infrastructure and Networking Group. Wave 2 will come next year, bringing even greater speeds and wireless ranges. That, combined with such trends as bring-your-own-device (BYOD), threaten to overwhelm current networks.
"It's evident that the backbone of these wireless access networks—1 gigabit per second Ethernet—can't keep up," Assouad wrote in a post on the company blog."Most companies pushing up against the limits of 1G-bps Ethernet are ready to make an upgrade, but their choices are limited. They can either jump up to 10G-bps Ethernet, the next available IEEE standard, or add a second, 1G-bps connection to double the bandwidth."
