Cel-Fi PRO for Spark 3G850 & 4G700/1800

The Cel-Fi PRO Repeater has been tested, authorised and approved by Spark for use on the Spark New Zealand Network.

Nextivity's third generation Cel-Fi PRO is a cost-effective and intelligent indoor coverage solution for the Spark 3G and 4G networks operating on the 3G 850Mhz and 4G 700/1800 bands. It is designed to dramatically boost indoor voice quality and increase data speeds for HSPA or LTE consumers.

Note: Cel-Fi PRO will boost 3G 850 and only one 4G band, either 700 or 1800 (not both 4G bands at the same time).

The Cel-fi PRO differs greatly from the standard indoor repeater due to its ability to not interfere with the mobile network or other users. Often referred to as a Smart Repeater, the Cel-Fi has the ability to provide maximum coverage, be network friendly and can be easily installed by the end user.

It does this in several ways by

  • continuously monitoring power levels of the cell tower it is connected to and constantly adjusting the Cel-Fi's output power to suit.
  • only amplifying and disbursing a particular carrier’s mobile signal, operating within a set frequency band.
  • not interfering with the carrier’s network or other users on the network.
  • having a unique installation process to eliminate feedback into the mobile network.

Cel-Fi PRO is covered by a 24 month warranty.
