Keeping the Right Perspective on Timing
By E.L. Fox, Jr.
Fox Electronics
Discussions about technology have the power to clarify or the power to confuse, depending on the perspective they take. And when you overlay business desires for smaller, more powerful, more economical, and more energy-efficient components, it becomes even easier to overlook the underlying physics behind technology options.

LightSquared:
The Show’s Over
…Or Should Be
By Barry Manz
There are a lot of very technically astute people at the Federal Communications Commission. Many have decades of experience at every level of RF and microwave technology. How then might LightSquared’s proposal for a satellite/terrestrial LTE network have ever gotten past its first hurdle? Even a cursory inspection of the plan, in which the company's network would operate extremely close to GPS frequencies at L-band, makes interference to GPS devices almost a certainty. Read More...

| In-Stat: Hotspot Usage to Reach 120 Billion Connects by 2015 |
Growth in the hotspot market has largely been driven by wireless and broadband providers embracing Wi-Fi as both a competitive differentiator and an enhancement to core services. New In-Stat (www.in-stat.com) research, Wi-Fi Hotspots: The Mobile Operator's 3G Offload Alternative, forecasts that this trend will continue as usage will increase to nearly 120 billion connects in 2015. The report states that global hotpot venues will increase to over 1 million in 2013 with transportation and convention centers accounting for a small percent of venues by nearly 30% of total connect. |

| Tahoe RF Semiconductor Offers LightSquared Interference Solution |
Tahoe RF Semiconductor has introduced an integrated dual-channel (L1 and L2 band GPS RFIC that substantially mitigates interference from LightSquared and 4G L-band LTE signals and other high-level interferer environments. The TRFS15011 integrates two independent receive paths with 12-b ADCs, digitizing the GPS signals. The IC has integrated fractional-N RF synthesizers with VCO's. The receive paths can be configured for high linearity by setting the ADC resolution to 12 b or for low power/low linearity operation by setting the ADC resolution to 3 b. The RFIC configuration is digitally controlled through a bidirectional interface. |

| SpiderCloud Wireless Demonstrates Self-Optimizing RAN |
SpiderCloud Wireless, founded by Michael Gallagher (formerly head of Flarion), has developed a technology for solving in-building wireless coverage problems that it claims will reduce the radio access network (RAN) to a self-optimizing package that becomes a seamless extension of the RAN. SmartCloud Cluster technology consists of small cells coupled via a local cluster controller and backed by intelligence over the Internet. It provides targeted capacity at a specific point of broadband use, such as within enterprises, high-rise buildings, college campuses, airports and convention halls. The company demonstrated the technology in a 100,000 sq. ft. office building with a single cluster controller and 18 Ethernet-linked small cells. All mobile voice and data traffic from 600 users was routed via the small cells to the live commercial core network. It handled a daily average of 3,000 calls and 50,000 data sessions. Individual users were able to downlink data from 5 to 10 Mb/s and uplink at 2 Mb/s. |

| Wireless Backhaul Via Satellite Shifts Focus |
According to research from NSR in its “Wireless Backhaul via Satellite” report, wireless backhaul is moving from serving traditional fixed land towers in rural areas of developing markets to mobility platforms such as cruise ships, container vessels, and commercial airlines. The company predicts global satellite backhaul market will grow to $1.9 billion in 2020, three times higher than today’s $64-million revenue. NSR's report predicts growth from less than 30,000 units in-service in 2010 to close to 85,000 by the end of 2020. In 2010, mobility platforms accounted for only 20% of the installed base but will be at least 55% by 2020, with the maritime market the largest portion of the market. |
