PG Electronics

Multiple antennas in a building complex can be connected to a wireless base station either directly, through a fiber optic link or through external antennas. Many large systems have been deployed over the past several years.

PG wireless distribution systems have been installed by national wireless carriers in every major indoor public concourse in Canada and in many commercial buildings in the US and Canada. The company specializes in the cost effective enhancement of modern enterprise buildings in the 100,000 to 400,000 square foot size range. PG is pleased to either sell the products or install them as turnkey projects.

The systems are suitable for trunking, cellular, PCS or two way paging systems and can be used with any modulation including AMPS, TDMA, iDEN, CDMA, or GSM/EDGE/UMTS.

The PG system utilizes repeaters, bidirectional amplifiers, couplers (splitters, taps, diplexers) and power supplies in conjunction with coaxial cable and antennas in an integrated cost effective system. The equipment can be connected in either star or pine tree systems to flexibly cover any building architecture. Fiber links are used for long runs.

An alarm system monitors the performance of all amplifiers in the system and reports deviations in downlink power output as well as internal circuit changes. All reports are logged. Any fault triggers a local alarm circuit and may report remotely through an optional dial up modem or dataphone. The faulty unit is identified. Third party equipment can also be monitored. The integrity of passive coax systems can be monitored using the PG Path Guard system which has been deployed in many US shopping malls.

Systems are available to distribute multiple frequency bands in a single cable. In the PG "Dual Band" system both 800 MHz and 1.9 GHz signals are amplified in a single amplifier chain to enable both cellular (or SMR) and PCS band signals to be radiated from common antennas. Existing 800 MHz coax systems can be upgraded to dual band without pulling any new cable. WLAN access can be integrated using the same antennas.

For small and medium sized buildings, conventional SAW filtered wireless repeaters are available in various gain and power levels instead of the distributed system.

P.G.Electronics has been manufacturing ultra linear feedforward amplifiers for the government and military market since 1980, and has established a reputation for reliable signal distribution equipment with very low intermodulation products. Products included receiver multicouplers, receive antenna matrices and tunnel communications systems for transportation and mining applications.
