The author is announcing a new report within its proprietary DNA-I series, a Nokia Solutions Networks W-CDMA/LTE 2100MHz B1 210W (3x70W) Flexi
3-sector radio module.

“This is their first opportunity to look into the 3-sector design philosophy for NSN’s outdoor radio module for its LTE eNodeB products. The Flexi 3-sector radio contains three complete radio transceivers, three power amplifiers and three duplexer filters to support 1x2 SIMO functionality. radio modules may be deployed to enable a 2x2 MIMO functionality per sector at the BTS site.

We note that this architecture is the most integrated and compact 3-sector radio design by any BTS OEM” said founder and President, Earl Lum.

The W-CDMA/LTE Band 1 unit supports the global 2100MHz frequency band in use worldwide for W-CDMA/HSPA services. It is also capable of supporting LTE services in this band although we believe the majority of units shipped are being configured as W-CDMA/HSPA. The author continues 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.
