Silicon Laboratories Inc. recently introduced an EZRadio® wireless IC solution designed to reduce the cost and complexity of one-way wireless links used in a wide range of consumer, industrial and automotive systems. The new Si4010 system-on-chip (SoC) RF transmitter enables developers to optimize remote keyless entry (RKE), garage door opener, remote control, building automation and security device designs for the lowest system cost and highest performance while ensuring one-way link integrity.
By Ray Chadwick, Berkeley Varitronics Systems, Inc. WiMAX signals suffer from the effects of multipath and exhibit broadband fading characteristics that are very apparent in the spectrum of the received WiMAX signal (see Figure 1). It’s not a trick; OFDM modulation does not eliminate fading and is not always received with a flat spectrum.
After three years of deliberation, the IEEE802.16m air interface definition will be ready for prime time in the next few months. This critical step toward creating true 4G cellular technology based on WiMAX is important enough to earn compliant products a new name: WiMAX 2. Further proof came last month, when an impressive subset of the WiMAX community created the WiMAX 2 Collaboration Initiative to "improve the economics of mobile broadband" and "to create a better value chain for service providers.
Freescale Semiconductor has introduced its MSC8155 digital signal processor (DSP), a higher performance and cost-optimized version of the company's flagship MSC8156 DSP based on the latest StarCore technology. The MSC8155 includes next-generation acceleration and interconnect technologies that boost overall chip performance and further enhance the capabilities of broadband wireless base station equipment.
By Svenn-Tore Larsen, Chief Executive Officer, Nordic Semiconductor Like many organizations in today's electronics sector, my company, Nordic Semiconductor, is rising to the challenge of operating in a global semiconductor market that analysts say could drop by around 20 percent this year compared to 2008.
Working closely with the test equipment vendor is required in order to synchronize feature implementation, reference specifications and timely delivery of the test equipment software. By Paul Gooding, Rohde & Schwarz click to enlarge Figure 1.
By David McCartney, Wavecom We in the wireless business have traditionally focused our efforts on the development and introduction of new, bleeding-edge technologies. Our priority has always been enabling the latest feature, smallest size or "killer" application. Well . . . those were the good old days! Today and for the foreseeable future we must be prepared to examine the 'value proposition' of our respective technology and product offerings.
