Which Frequency?

  • 4G (also called LTE) is for high speed data only. It cannot be used for voice calls.
  • 3G , (also called UMTS), is for voice and 3G data. Data speeds are not as fast as 4G.
  • 2G, (also called GSM) is for voice calls only.
Telecom RF Signal 2G 3G 4G LTE Wireless In-Building Cellular Coverage Solutions & Broadband Repeaters 900 1800 2100 2600 in mobile communication repeaters would be an optional solution to cover areas that can not be covered by base stations.
Main features
1, high system gain and the gain is continuously adjustable;
2, full duplex operation, high / down isolation;
3, with automatic start and stop function devices, reducing the demand for professional engineers;
4, two-port standard design, installation is very easy;
5, the device uses the Integration of methods to improve stability of the equipment;
6, using ALC control, continuously adjustable output level;
7, intelligent monitoring, fault alarm and remote maintenance (remote feature is optional);
8, high linearity power amplifier, stable performance;
9, the design of lightning protection, lightning protection systems.
Application Scenarios
In order to expand the coverage of fill signal blind area, the signal is weak or unavailable.
Outdoor: Airports, tourism regions, golf courses, tunnels, factories, mining districts, villages and so on.
Indoor: Hotels, exhibition centers, basements, shopping malls, office buildings, and other packaging area.

Mainly applicable to this case:
Repeaters can find the installation place can receive pure BTS signal at strong enough level relay station as the reception level should exceed -70dBm; and to meet the requirements of the antenna isolation, in order to avoid self-oscillation.
