Passus is a leading supplier of devices amplifying the radio systems signal. Our offer contains devices improving the signal range both for open air and indoor applications. Our main supplier is Powerwave – a company manufacturing equipment meeting the world's highest requirements. Powerwave’s offer is supplemented with products from Remotek, thus expanding our portfolio to a full array of solutions. The quality of the equipment supplied is proven by our list of customers – we supply active equipment to all mobile carriers in Poland, and also to several foreign ones.
Repeaters
Boosters
Repeaters are an ideal solution, guaranteeing coverage in airports, tunnels, sports facilities and many other locations, as they provide the appropriate radio signal strength at minimum costs. The use of repeaters for indoor installations also allows the reduction of the expenses related to the power supply, radio equipment, device cooling, and combining of radio signals from multiple carriers.
Repeater types:
• channel-selective repeaters – due to its higher selectivity, channel-selective repeaters are a better solution for urban areas. The amplification of specific channels is more suited to environments with intensive interference.
AR1700 - channel repeater (1-8) GSM
AR6500 - channel repeater (1-4) UMTS
• band-selective repeaters – the bulk of the offered repeaters are repeaters amplifying the entire frequency bands. These are a cheaper alternative for channel-selective repeaters. We offer both low- and high-power repeaters operating in one or several bands. Our suppliers are Powerwave and Remotek.

ATR6200 - train repeater UMTS
• fiber optic devices – the application of fiber optics as a medium for signal transmission is not a novelty. Due to low losses, this technology is used in repeater equipment in order to guarantee signal coverage for large facilities
The application of boosters allows for the cost-efficient improvement of radio signal coverage. Their installation in the base station increases the radio signal power emitted from the antenna, reducing the negative impact of combining multiple signals into one cable route. Booster-based signal strengthening also allows the increase of the cell radius and the expansion of the range of advanced services, i.e. HSDPA, EDGE, etc. by improving the signal-to-noise ratio.
