An agreement has been finalized through which the Shared Spectrum Co.’s (SSC) dynamic spectrum access (DSA) technology will be integrated into Thales Communications Inc’s field-ready military radios. The agreement is part of Phase III of the neXt Generation Communications (XG) Program being managed by the Defense Advanced Research Projects...

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). Furthermore, both systems have been installed and are being actively used for WiMAX equipment certification at the...

Following Thailand’s purchase of an integrated air surveillance system from Sweden in a government to government deal, FMV, the Swedish Defense Material Administration, has placed a contract with Saab valued at $310 M for the development and production of the systems. Deliveries will take place during 2011. The order...

WiMAX supporters have had a turbulent time of late. On the downside, last year’s breakup of the Sprint Nextel-Clearwire partnership to roll out a mobile WiMAX network across the United States has raised serious questions about the growth potential of this wireless technology. Verizon Wireless also announced last November...

Just as operators and vendors are continuing to enhance HSPA even with LTE on the horizon, so they are still finding a strong place for the 2G+ technology EDGE, and combining with this system will be a major opportunity for WiMAX. One of the most important markets for Mobile...

Whatever your perspective, be that from the position of a small operator who hopes to gain a market advantage, or of a large incumbent supplier or network operator, the fundamental question about WiMAX is whether it can ramp to volumes that enable it to compete in a world ruled...

A new report by the Maravedis analyst firm predicts the number of WiMAX subscribers worldwide will top 100 million by 2014.

The technical definition of an amplification class is not obvious. Patents are among the best documents to explain and define what an amplification class is. 1,2 Reviewing the claims sections of those documents is an interesting exercise in understanding the inherent complexity of an amplification class definition. From a...

In recent years, wireless communications have progressed very rapidly. Broadband antenna design has become very important for wireless applications. UWB is a high data-rate and short-range wireless technology, utilizing the unlicensed radio spectrum from 3.1 to 10.6 GHz. The UWB antenna is one of the major components of UWB...

Commercially available 5 GHz WLAN transceivers—with the exception of power amplifiers (PA)—have recently been using advanced CMOS and SiGe BiCMOS technology. 1 It is commonly believed that RFICs made with Si technology, especially CMOS technology, have the lowest cost and can be easily integrated with digital CMOS ICs to...
