Anite says it now has PTCRB validation for the highest number of LTE-Advanced carrier aggregation (CA) protocol tests in the industry, after working closely with chipset and device manufacturers in the U.S., Korea and China to develop the test cases.
The PTCRB is a wireless...
Ericsson and Australian carrier Telstra announced that they have made the first call on combined 1800 MHz and 900 MHz spectrum bands in a commercial network, using the LTE-Advanced feature carrier aggregation.
The call took place on July 31 via a transfer of data across...
Carrier aggregation is picking up speed. Several test companies have now announced submissions for validation and other testing for the eagerly anticipated LTE-Advanced feature. The first LTE-A device supporting CA was announced this week, when Qualcomm revealed that its Snapdragon chip is powering the...
Qualcomm Technologies Inc. is enabling the industry's first LTE-Advanced smartphone, the Samsung Galaxy S4 LTE-A, with its Snapdragon 800 processor.
Qualcomm said that the new Galaxy S4 LTE-A will be launched on all three mobile operators’ LTE networks in Korea, starting with SK Telecom, and...
Anite says it has submitted the first LTE carrier aggregation (CA) protocol test cases for verification to 3GPP's RAN Working Group 5 (RAN5), Â key step toward validation that would lead to the test cases being included in both the Global Certification Forum and the...
Anritsu Co. is giving the first ever single-instrument radio frequency testing of carrier aggregation at CTIA 2013, the company said. Carrier aggregation is one of the most highly anticipated features of LTE-Advanced, and allows wireless operators to make more efficient use of their spectrum.
The...
QRC Technologies launched a wide-band transcorder this week, which it describes as a self-contained radio frequency recording and playback system designed to allow technicians to record network conditions in the field and transport or e-mail the information for troubleshooting.
QRC is aiming the product at...
While device makers are pushing to deliver download speeds of 150 megabits per second, chipmaker Sequans is promising speeds twice that fast through carrier aggregation. Carrier aggregation is the combination of spectrum from different bands, and Sequans today introduced an LTE-Advanced modem that the...
Carrier aggregation is creating new opportunities for carriers to make better use of their spectrum, and now the technology has made its way onto the chips that power small cell base stations. LTE modems that aggregate frequency bands have been used in smartphones, but...
Achieving the requirements for carrier aggregation detailed in Release 10 of the 3GPP LTE specifications is even more challenging given the fragmentation of the available cellular radio spectrum, particularly in North America. Learn about carrier aggregation testing implications for LTE-Advanced. This is an Anritsu...
