10 NEWS By JP Joosting, Microwave Engineering Europe IN BRIEF Conformance testers now ofﬁcial for WiMAX Certiﬁcation Aeroﬂex and AT4wireless have announced that the WiMAX Forum has designated the Aeroﬂex/AT4 wireless MINT223x protocol conformance test (PCT) system and AT4 wireless MINT T2110 radio conformance test (RCT) system as ofﬁcial test equipment for WiMAX Certiﬁcation (802.16-2005). Both systems have been installed and are being actively used for WiMAX equipment certiﬁcation at the ﬁrst worldwide WiMAX Forum Designated Certiﬁcation Laboratory which has been established on behalf of the WiMAX Forum within AT4 wireless’ comprehensive Wireless Certiﬁcation and Testing Laboratory in Malaga, Spain. According to the company, the early availability of quality WiMAX test equipment is crucial to the ongoing development of the WiMAX market both in terms of infrastructure and subscriber equipment. www.mwee.com/206801245 French wireless IP provider joins Xilinx Alliance R-Interface, provider of wireless IP and design services for digital system communications in telecom, broadcast and military markets (Marseille, France), announced it has joined the Xilinx Alliance Program. The Xilinx Alliance Program gathers companies in the areas of IP cores, EDA, DSP and embedded development tools, as well as design services, board-level products, integrated circuits and electronic components. Members provide optimized products and services that contribute to a broad selection of industrystandard solutions dedicated for use with Xilinx FPGAs. In parallel, R-Interface introduced a Low Density Parity check (LDPC) platform IP core optimized for Xilinx 65-nm Virtex FPGA and low-cost Spartan FPGA families. The LDPC platform IP powers a family of fully standard and proprietary LDPC solutions such as WiMAX mobile, WiFi-11n, DVB-S2/T2, DTMB and Power Line Communication, the French startup stated. R-Interface speciﬁed that the ﬁrst member of its LDPC family is compliant with the WiMAX Mobile (802.16e) standard. Thanks to its modular Processing Module approach and its advanced memory management, it can achieve up to 1Gbit/s possible in the smallest possible gates count, the company claimed. www.mwee.com/206800243 Nujira, Sumitomo link up to provide greener PAs in 4G applications Nujira Ltd, a start-up that has patented and developed efﬁcient power ampliﬁers for wireless infrastructure, has sealed its ﬁrst major OEM deal, and is working with Japan’s Sumitomo Electric Industries (SEI) to develop power efﬁcient RF power ampliﬁers for WiMAX and LTE basestations. The deal is signiﬁcant because Japan often leads the way in the cellular industry, and Nujira’s High Accuracy Tracking (HAT) technology could play a major role in enabling more energy efﬁcient and environmentally friendly next generation base stations for the Japanese and global cellular markets. Under the terms of their agreement, announced at the Mobile World Congress in Barcelona, Spain, SEI will develop and market high power RF ampliﬁers targeted at next generation cellular base stations using Nujira’s HAT module. www.mwee.com/206801292 Sequans, Tecom partner on WiMAX product development Resulting from a collaborative work, French WiMax chip supplier Sequans Communications SA (La Defense, France) and Taiwanese telecom equipment provider Tecom Co. Ltd. have introduced a WiMAX product series that includes Mobile WiMAX Wave 2 base stations and subscriber stations using Sequans’ chip solutions as the main design platform. Tecom said it is using Sequans’ SQN1130 mobile station chip, which is WiMAX Forum Wave 2-ready, including both PHY and MAC layers and 2X2 MIMO. Patent-pending mimoMAX enables the SQN1130 to deliver maximum likelihood MIMO performance with low power consumption, claims the French company. Both parties have demonstrated pico and femto base station units as well as end user devices www.mwee.com/206503736 UK mobile operators to trial broadcast mobile TV based on TDtv technology Mobile operators Orange and T-Mobile are to trial a broadcast mobile TV service in London this year that will use existing cellular spectrum and use NextWave Wireless’ TDtv technology. The TDtv technology was originally developed by IP Wireless, (Chippenham, England) which NextWave (San Diego, Calif.) bought last April for a minimum of $100 million. The technology pools spare capacity in both operators’ UMTS networks to deliver a multicast service to handsets equipped with special chipsets. The pilot, scheduled for the second half of 2008, follows successful technical trials of the TDtv technology last year in the Bristol area by several operators. The companies said the trials showed that TDtv can mirror WCDMA coverage with less base stations than those needed by the cellular network, and successfully deliver TV broadcasts to phones in moving vehicles. The deployment of TDtv technology by two tier-one European operators could be a severe blow for the future prospects of rival broadcast mobile TV technology DVB-H — which although it has been around for much longer and has received the ofﬁcial endorsement of the EU, has so far only been deployed in a handful of countries. www.mwee.com/206801323 Microwave Engineering Europe ● March 2008 ● www.mwee.com 010_MWEE.indd 10 22/02/08 17:14:59 http://www.mwee.com/206800243 http://www.mwee.com/206801245 http://www.mwee.com/206801292 http://www.mwee.com/206503736 http://www.mwee.com/206801323 http://www.mwee.com
