There has been much discussion lately about spectrum limitations in light of the market’s ever-increasing appetite for mobile data services. As we look ahead to fourth generation technologies, we recognize that asymmetrical duplexing associated with TDD (Time Division Duplex) will yield some efficiencies over the inherent symmetry of FDD (Frequency Division Duplex). TDD has the additional advantage of being unpaired from an RF channel perspective — allowing for more spectrum allocation flexibility for fourth generation technologies.

LTE’s TDD specification known as TD-LTE is gaining momentum in light of these advantages. In this article, from Fierce Broadband Wireless, Monica Paulini gives us a superb snapshot of the current state of 4G technologies, and what the future likely holds in light of where we are today. She views TD-LTE as “disruptive”.

WireIE is currently deploying a 20-site backhaul project that entails installing and testing Dragonwave microwave equipment.

The result of this project will be an all-IP HSPA network, which will pave the way to an LTE network in the future.

The project also utilizes WireIE’s best-in-class Project Management expertise for the defined installation process and methodologies. WireIE has created a streamlined installation of one site per day, in comparison to the 3-4 days previously required to complete a site install.

WireIE’s engineering team enhanced the quality of the installs they previously received from other subcontractors through staging and an implementation test plan.
