For transitioning from WiMAX to LTE, 4G chipmaker Sequans Communications and 4G solutions provider Greenpacket offer what they call the industry’s first 4G WiMAX and LTE TDD indoor dual-mode integrated access device (IAD). The DA 235 dual-mode customer premises equipment promises to deliver uninterrupted service to users connecting to either WiMAX or LTE networks. It relies on Sequans’ SQN5120 dual-mode IC, which integrates WiMAX and LTE on one die. The DA-235 features multiple-input multiple-output (MIMO) A&B, switched transmit diversity, maximal ratio combining, and a 5-dBi omni antenna. Compliant with current LTE Category-4 (3GPP- R9) and WiMAX 802.16e-2009 standards, it delivers downlink/uplink speeds to 150 Mbits/s and 50 Mbits/s for LTE TDD and a combined speed of 40 Mbits/s for WiMAX. Wi-Fi 802.11n, one LAN port, and one RJ-11 port are also on board. More details on the DA-235 are available at www.greenpacket.com/da235-wimax-lte-modem.html.
