Centralized Intelligence Delivers Higher Spectral Efficiency and Greater Flexibility in Mobile Networks

Wed, 03/23/2011 - 12:00pm
MINNEAPOLIS -- (BUSINESS WIRE) -- TE Connectivity (TE) today announced that the new trend toward distributed radio intelligence in mobile networks may be a trip down the wrong path, and that centralized radio intelligence offers lower costs, better scalability, higher spectral efficiency and greater flexibility for mobile operators.

TE will showcase its portfolio of Distributed Antenna Systems (DAS) solutions at the International CTIA show to be held in Orlando, Florida, March 22-24. In addition, TE will display its new RAPID fiber panel, the latest addition to its RAPID product portfolio that significantly reduces installation time and labor costs for turning up new fiber equipment. These solutions will be shown in booth #2418 at the show.

While many large system vendors are embarking on strategies that distribute small radios throughout the network to create the small-cell architecture that will be required for LTE and other advanced services, TE believes that there are better ways to solve the problem.

Using distributed radios may cause carriers to overbuild capacity when it’s not necessary, while centralized network intelligence provides equivalent coverage capability and does it in a way that uses spectrum and other resources more efficiently.

“Distributing radios throughout the mobile network means geometric expansion in backhaul and maintenance costs while making it more difficult to use spectrum efficiently,” says Chris Jurasek, vice president of TE Wireless & Services. “In contrast, our distributed antenna systems rely on centralized radio resources that are much easier to backhaul, maintain, and upgrade over time.”

TE will display three DAS solutions at CTIA:

* InterReach Fusion – an in-building DAS that uses a single set of electronics to support two sets of frequencies.

* InterReach Spectrum – in-building DAS that supports up to eight licensed mobile frequencies with a single set of electronics and integrates with TE’s outdoor DAS.

* FlexWave Prism – an outdoor DAS that allows mobile operators to extend multi-band, multi-service outdoor coverage and capacity through a system of compact, inexpensive remote antennas.
