To boost both power and performance, Airspan Networks is upgrading its next-gen Air4G 4G Long-Term Evolution (LTE) basestations with XLP316L multicore processors from NetLogic Microsystems. An XLP316L processor core features quad-issue, quad-threading, and superscalar out-of-order execution that teams with a floating-point unit and a tri-level cache architecture. The 40-nm based processor integrates 16 NXCPUs operating at speeds to 2 GHz, security functions supporting SNOW3G and KASUMI protocols, multiple SRIO interfaces, and IEEE 1588v2 hardware time stamping. Operating in the 700-MHz, 1.4-GHz, 2.3- to 2.7-GHz, and 3.3- to 3.8-GHz bands, Airspan’s Air4G basestation integrates capabilities like multiple-input multiple-output (MIMO) and advanced frequency domain scheduling, which promise higher throughput and capacity plus more efficient spectrum use. The basestation includes two to four transmitters and two to four receivers and can pair up with a remote radio head.
