CellAir indoor mobile coverage

An international product in development, with regional radio options for buildings with weak mobile reception.

International platform

Regional radio options. A shared platform.

Operator support depends on the bands, channels and installation requirements in each market.

Multiple operators

Radio options selected for the intended networks and their available outdoor signals.

Regional configurations

RF modules, antennas and power options matched to each target market.

Designed for the site

Donor placement and indoor antenna layouts based on the building and measured reception.

Concept design

System architecture

Outdoor reception, a protected repeater, and indoor signal distribution.

A bidirectional path connects the mobile network, outdoor donor antenna, protected feeder, band-selective repeater, indoor service antenna, and indoor devices.
