A system’s wireless coverage is impacted by construction materials, certain shielded areas, antenna positioning, antenna height, and overall transmitter power. For small facilities such as a small grade school or office, the internal transmitter in the VS4820 paging base station will suffice. For medium facilities like a commercial building or warehouse, our 10W transmitter can extend the range significantly. For larger facilities with multiple buildings, floors, and a lot of square footage to cover, we recommend our 40W transmitter.
