Begin with the operator bands in use and the outdoor signal level at the installation point. If outdoor coverage is weak, pair the unit with a high-gain directional antenna aimed precisely at the serving base station. Indoors, choose ceiling omnidirectional or panel antennas according to floor area and wall attenuation. Host gain, output power and uplink-downlink balance decide the final coverage, and excessive gain causes self-oscillation, so plan enough antenna isolation. Multi-band models cover 2G, 3G, 4G and 5G at the same time. Typical sites are tunnels, basements, warehouses and remote facilities. A site survey before installation and a coverage test at handover avoid most call-quality complaints.
Frequently asked questions
Can a booster be added to any weak indoor area?
A site survey comes first. If outdoor signal is weak, use a high-gain directional donor antenna aimed at the serving base station; indoors choose ceiling omnidirectional or panel antennas by floor area and wall attenuation.
Will it affect the mobile network?
With correct gain and uplink-downlink balance it operates normally. Maintain enough isolation between donor and service antennas to prevent oscillation, and keep coverage inside the target area.
Does it support multiple bands?
Yes. Units can combine 2G, 3G, 4G and 5G bands according to the operators active at the site, and a band reference table is supplied with each unit.
