The African cellular market is very much pulling in the subscribers. In 3Q-2012, the 54 countries and 1.08 billion people have accumulated 821 million subscriptions, up 16.9% year-on-year, resulting in a cellular subscription penetration of 76.4%. In the first quarter of 2013, cellular penetration will eclipse 80%. Given the fact that a significant percentage of prepaid users maintain more than one active prepaid subscription to minimize interconnection charges, there is still subscriber growth to be had.

Describes three design techniques and how each approaches system efficiency and power management from different angles

Looks at some of the leading test and measurement and semiconductor device manufacturers and what they think will be the hot topics and key technologies for Mobile World Congress 2013 in Barcelona

Aeroflex Ltd., a wholly owned subsidiary of Aeroflex Holding Corp., announced support for a comprehensive range of IP data services with the Aeroflex E500 LTE Capacity Test platform. Adding end-to-end data services supplements the industry-leading functional capability of the E500, providing network equipment vendors and cellular operators with the most realistic lab-based LTE end-to-end test solution on the market.

Cree Inc. introduces a range of new 50V GaN HEMT devices enabling a significant reduction in the energy needed to power cellular networks. The world’s cellular network is estimated to consume more than 100TWh of electricity per year (approximate value of $12 Billion US Dollars) and 50-80 percent of the networks’ power is consumed by the systems’ power amplifiers and feed infrastructure.

The demands of cost reduction and greater efficiency in cellular base station design are leading to a rapidly growing market for remote radio heads. According to a new study from ABI Research, this market is on track to exceed a value of $1 billion in 2017. Cellular base stations are now undergoing a design revolution. A base station was traditionally a rack of equipment inside a shelter. That design is now becoming anachronistic because it is expensive, and because the required coaxial cable running up the tower to the antennas often results in significant losses of power.

Agilent Technologies Inc. announced it will demonstrate its newest LTE and WLAN test and measurement solutions, which cover the global technology and applications ecosystem for next-generation mobile broadband networks, at 4G World (Booth 322), McCormick Place West,  in Chicago, Oct. 30-31.

Skyworks introduces a 2.3 to 2.8 gigahertz, two stage, high linearity and high gain (32 dB) low noise amplifier that offers very low noise figure (0.85 db) and excellent return loss (15 db) in a small 4 mm square quad flat, no lead package.

Communication devices for the public safety, utilities, transportation, military, and other “second responder” sectors are often characterized by images of clunky, large instruments that look like they require a master’s degree to operate. Yet these are the type of urgent communication systems that should be quick and easy to operate in order to protect and save lives.

National Instruments introduced test solutions for 802.11ac WLAN and Bluetooth low-energy technology that combine NI graphical system design software and modular, FPGA-based PXI instrumentation to provide high-performance test capabilities that are completely user-programmable. These test solutions along with other cellular, navigation and wireless connectivity solutions from NI, help engineers thoroughly test their devices on a single high-performance platform.
