In a major technology development for the mobile industry, Ooredoo has collaborated with CommScope to develop a new approach to building wireless networks, which will improve installation quality and on-going network performance and reduce deployment times, in an alliance that could have major benefits for operators around the world.

Sierra Nevada Corp. (SNC) delivered the first low rate initial production (LRIP) Mobile Tower System (MOTS) to the United States Army ahead of schedule. The LRIP contract was awarded in March 2012 for 10 MOTS. 

NXP Semiconductors N.V. introduced a groundbreaking family of programmable AISG transceivers for wireless base stations and antenna line devices (ALDs) such as tower-mounted amplifiers (TMAs) and remote electric tilt (RET) antennas.

Radio Frequency Systems (RFS), the global wireless and broadcast infrastructure specialist, announced that it has introduced a new addition to the CompactLine® series of microwave antennas with the release of the 6 GHz Category A SB6-W60B. Featuring a wind-tunnel tested design suited for both tight urban locations and rugged outposts, the SB6-W60B offers a superior radiation pattern for consistent performance with less interference.

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.

Tower top RF electronics, consisting of active antennas, remote radio heads, and tower mounted amplifiers, are important parts of modern macro base station hardware.

As the mobile network struggles to cope with the growing level of traffic and pressures on CAPEX, the RF electronics of a typical base station design are subject to great innovation namely in the form of tower mounted amplifiers, remote radio heads, and active antennas.

Tower mounted amplifiers have now become a common addition to most macro base station systems. They increase overall system performance and are now easily mounted and monitored. Tower mounted amplifiers can provide significant BTS performance improvement for a moderate investment. Lance Wilson, research director, mobile networks, notes, “The use of tower mounted amplifiers in wireless infrastructure base station systems represents one of the most cost effective ways of improving overall system performance.”
