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.
AR Modular RF has received JITC certification for its KMW2030 tactical radio amplifier system (30 MHz to 512 MHz / 125 watts) when used with the Harris PRC-117G tactical radio. It has been previously certified for use with the PRC 117F and the PSC-5D. The KMW2030 was tested along with its associated low noise SATCOM pre-amp, the KMW2030P.
Virginia's Region 2000 Local Government Council has selected advanced, standards-based digital technology from Harris Corp. to improve and unify mission-critical communications for more than 3,000 first responders and public works users. Region 2000 includes 184,460 residents in Bedford and Amherst Counties, the Cities of Lynchburg and Bedford, and the Town of Amherst.
Sumitomo Electric Device Innovations USA Inc. (SEDU), a provider of advanced wireless and optical communications solutions, will showcase its E-band MMICs for radio link applications at IMS 2012 in Montreal.
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.”
NEC Corp. has completed a contract to provide its iPASOLINK microwave backhaul series to the Belgacom-Cassidian consortium, which will replace one of the major building blocks of the Belgian ASTRID radio communications network.
Thales and Nokia Siemens Networks have a MOU covering the EMEA region, which aims to provide a broadband LTE solution for high speed data communication to Professional Mobile Radio users.
DragonWave Inc., a leading global supplier of packet microwave radio systems for mobile and access networks, announced the availability of higher modulation modes of up to 2048 QAM on its Horizon packet microwave products. This higher modulation allows the radios to transport up to 37 percent more data through existing microwave channels, which significantly improves spectral efficiency and, correspondingly, lowers operators' cost per bit.
