The number of Wi-Fi enabled devices shipped in 2012 is expected to surpass 1.5 billion. Growth is occurring across many markets including mobile handsets, laptops, media tablets, printers, TVs, and automotive. “Since 2009 over 9 billion Wi-Fi enabled devices have been shipped,” commented Peter Cooney, wireless connectivity practice director, “whilst growth was driven by networking in the early years the smartphone soon became the major market.

Nujira Ltd., the world leader in envelope tracking (ET) technology, has announced that is sampling its next generation ET IC for mobile handsets, the NCT-L1200, to lead partners. The second product in its Coolteq.L ET product family, Nujira’s NCT-L1200 has already been delivered to several key platform chipset vendors, and is the only product currently available on the market that supports the maximum 20MHz channel bandwidth of LTE.

Wireline operators have been the largest market for IMS services to date, but due to an increase in the number of mobile IMS deployments, ABI Research forecasts IMS revenues to reach $3.4 billion in the next five years.

Wireless infrastructure equipment revenues continued their downward trend in the second quarter of 2012 reaching only $11.2 billion – a 4.7 percent decrease from the first quarter of 2012 and a 14 percent decrease from the same quarter one year ago. “Total revenues for wireless network equipment reported by the vendors was the lowest amount that we have seen since 3Q 2003; reaching a 35 quarter low,” says Nick Marshall, principal analyst, networks.

Linear Technology’s Dust Networks® product group introduces the SmartMesh™ LTC5800 (system-on-chip) and LTP5900 (module) families, the industry’s lowest power IEEE 802.15.4E compliant wireless sensor networking products. SmartMesh ICs and modules enable tiny sensor “motes” to be designed with a battery life of over 10 years, while companion network manager components enable the development of highly robust and secure wireless sensor networks (WSN).
