The 2014 Mobile World Congress that was held from 24 to 27 February in Barcelona is billed as an industry-defining event; though the pace at which the mobile telecommunications industry continues to evolve makes the accurate definition and prediction of trends and especially their timescale for implementation a difficult task. However, having all of the major players under one extensive roof offers the opportunity to take stock, gauge opinions, talk to innovators at the forefront of technology and hopefully be able to see the wood for the 4Gs (or is that 5Gs now?).
In a joint effort, Rohde & Schwarz and Qualcomm Technologies Inc., a wholly owned subsidiary of Qualcomm Inc., have extensively tested the user plane throughput of the new Qualcomm® Gobi™ 9x35 chipset in compliance with 3GPP Release 10 for LTE-Advanced. In the setup on display at Mobile World Congress, the R&S CMW500 wideband radio communication tester from Rohde & Schwarz simulates the LTE-Advanced network.
Skyworks Solutions Inc., an innovator of high performance analog semiconductors enabling a broad range of end markets, unveiled a set of antenna switch solutions supporting LTE, LTE-Advanced and next-generation carrier aggregation architectures. The portfolio includes highly integrated antenna switch modules (ASM) as well as transmit and receive diversity switches. The dual-mode MIPI® RFFE-compliant modules are modem agnostic, making them compatible with every leading chipset provider.
Skyworks Solutions Inc., an innovator of high performance analog semiconductors enabling a broad range of end markets announced that it has unveiled its second-generation SkyOne™ platforms. SkyOne™ is a family of fully optimized, scalable devices that integrate all of the high-performance RF and analog content between the transceiver and antenna into the industry’s smallest footprint.
Aeroflex Ltd., a wholly owned subsidiary of Aeroflex Holding Corp., announced that the 7100 Digital Radio Test Set provides LTE-A carrier aggregation testing at full Cat 6 data rates of 300 Mbps downlink and 50 Mbps uplink simultaneously for LTE-A in FDD mode, and now also supports carrier aggregation in TDD mode.
TriQuint Semiconductor Inc., a leading RF solutions supplier and technology innovator, announced several new premium filters for next-generation smartphones and other mobile devices. The high-performance filters utilize the company’s advanced acoustic wave filtering technologies to address some of the industry’s toughest LTE interference problems.
Aeroflex Ltd., a wholly owned subsidiary of Aeroflex Holding Corp., has launched an extended version of its TM500 industry-standard base station tester capable of emulating several thousand LTE user equipments (UE), fading channel models, and LTE-A carrier aggregation functionality in a one-box benchtop unit. The TM500 Test Mobile delivers more leading edge LTE-A development capability with a higher UE density than any other solution on the market.
