Smart Cel-Fi Boosts Signal

Smart Communications has begun using Cel-Fi, a signal-boosting device that eliminates dead spots inside homes and offices in the Philippines.  It said the device also improves mobile reception for voice and data in enclosed spaces.

Smart Chief Wireless Advisor Orlando Vea said these indoor dead spots may be may be attributed to nearby physical obstructions causing signal degradation and result in dropped calls, delayed messages and crawling upload and download speeds.

“As the leader in wireless services, Smart has continually been on the lookout for new technologies that can enhance the consumers’ mobile experience and offer the best value for them,” said Mr. Vea.

"Cel-Fi offers a lot of promise because it functions much like a personal cell site and boosts the network performance in corners where signal strength is challenged.”

The Cel-Fi taps at least one bar of available 3G signal and amplifies it, effectively boosting both 3G and 4G HSPA+ mobile connectivity throughout a specific area.

Designed by US-based Nextivity, the device can handle 60 simultaneous calls and support high-speed connections reaching 42 Mbps in an area of up to 1,200 sq. m., making it ideal for homes and small offices.

A set of Cel-Fi consists of a window unit and coverage unit, which communicate to each other wirelessly. The window unit is meant to be stationed at a spot where the strongest signal from the network carrier is received.

The coverage unit is also positioned at the center of the house or a building.

When powered up, the window unit relays whatever signal it receives to the coverage unit, which then cleans the signal, converts it and amplifies it throughout the whole area.

The Cel-Fi is a plug-and-play device and may be installed in minutes with no need for cables, antennas or configuration.

It relies on self-organizing algorithms to maximize coverage area and makes sure it does not interfere with mobile operator networks or impede the signals of other subscribers.

Compliant with the strict standards of the Federal Communications Commission, Cel-Fi is authorized for use by 120 mobile operators around the world, including AT&T and T-Mobile.
