With initial LTE network deployments for coverage nearly completed for 700MHz in the US market, we expect the AWS 17/2100MHz spectrum to be the key band for capacity for LTE/LTE-A.


Ericsson has made mechanical cost cutting changes to this version of the RRUS11 as compared with prior versions.

EJL Wireless Research is announcing a new report within its proprietary DNA-I series, an Ericsson LTE 17/2100MHz B4 80W (2x40W) RRUS 11 unit.

“This is our third opportunity to look into the 2x2 MIMO design philosophy for Ericsson’s current generation remote radio unit in volume production and has allowed us to see further design changes in the semiconductor ASICs and FPGAs used for the digital processing of the RF signals along with a lower cost mechanical design/construction of the system. The RRUS 11 contains two complete radio transceivers, two power amplifiers and two duplexer filters to support 2x2 MIMO functionality. The RRUS 11 is part of the RBS6601 Main/Remote BTS system and is the multi-standard radio architecture version of Ericsson's remote radio units that supports GSM, CDMA, W-CDMA and LTE technologies” said founder and President, Earl Lum.

“The LTE Band 4 unit supports the AWS-1 blocks of spectrum within the 2100MHz frequency band in North America. Band 4 spectrum supports mobile operators including AT&T Wireless, T-Mobile USA and Verizon Wireless in the US as well as Rogers, TELUS, Bell Mobility, Wind Mobile, Videotron and Mobilicity in Canada. We continue to be excited in having the opportunity to showcase the latest generation remote radio units, RF transceiver modules, BTS antennas, femtocells and base stations from major wireless equipment OEMs as part of our DNA-I program,” says Lum.

EJL Wireless Research continues to lead the wireless market research segment with innovative and cutting edge research such as its DNA-I series of products.

The following semiconductor & passive component suppliers are included in this report: Analog Devices, Broadcom Corporation, Fairchild Semiconductor, Freescale Semiconductor, Infineon Technologies, Micron Technology, Nippon Chemi-Con, NXP Semiconductors, STMicroelectronics, Texas Instruments, and Vishay Semiconductors.
