Sequans Ups Uplink Performance with WiMAX Expo Taiwan Announcement
Sunday, June 29th, 2008 – 1:33 pmSequans Communications announced new WiMAX chipset capabilities this week at the opening of the WiMAX Expo in Taiwan. The provider enabled a second transmitter in its 802.16e-2005 silicon to boost performance using uplink MIMO. The additional transmitter could lead to infrastructure cost-savings of up to 50 percent.
Sequans is enabling the second transmitter in its mobile station semiconductor products to boost Mobile WiMAX system performance. The company claims it is the only WiMAX provider offering this capability across its entire product family. As a result, smart antenna techniques applying MIMO in the uplink (device to infrastructure base station) are now possible in addition to the downlink. “The benefits of uplink MIMO cannot be ignored,” said Georges Karam, Sequans CEO. “WIMAX network operators’ recent experiences show that, as in other wireless networks, coverage is limited by the uplink. With the diversity introduced by uplink MIMO, up to a 50 percent reduction in infrastructure costs can be achieved with very little incremental cost to the mobile device and no incremental cost at the base station.”
