HOW MANY BARS CAN YOU SEE?

The answer is hopefully five, meaning that you should have a very strong connection. Your signal may also be showing good numbers. But the strength of a connection or a sharp signal don’t necessarily promise an interference-free or a high-quality reception.

Who’s interfering with who?

Probably another signal broadcasted from a nearby base station. When base stations are close to each, broadcasted signals often collide. This leads to interference and disrupted communications, even when five bars for connectivity appear on your mobile device.

Perhaps it’s LTE

Long Term Evolution or LTE is a technology standard for high-speed wireless communications via cellular networks. Unlike 2G and 3G policies that split broadcast load among base stations to avoid interference, LTE broadcasts over the entire spectrum of a base station. While improving network speed and capacity, LTE has also increased the amount of interference on communication lines.

Or is it EDGE

Enhanced Data Rates for GSM Evolution or EDGE streams media on mobile phones. A convenient way to simplify, optimize and analyze wireless networks, using cell EDGE technology mobile phones receive signals on the same frequencies from both main and secondary base stations. Since both base stations are a similar distance from the mobile phone, communications are disrupted and calls are disconnected even when five bars for connectivity appear on a user’s mobile.

Alvarion’s no interference solution

Following the release of 4G technologies, Alvarion looked for a solution for the interference issue. Their answer was either that both base stations broadcast over the same frequency or that the secondary base station would broadcast on a lower frequency.

The process is initiated when a mobile device receives a call. The device automatically notifies the main base station and updates it on the signal’s frequency. In turn, the main base station updates the secondary base station which then broadcasts over the same or at a lower frequency.
