Page 11: Introduction
Introduction The 4RF Aprisa SR+ Radio The 4RF Aprisa SR+ is a point-to-multipoint digital radio providing secure narrowband wireless data connectivity for SCADA, infrastructure and telemetry applications. The radios carry a combination of serial packet data and Ethernet data between the base station, repeater stations and remote stations. -
Page 12: Product Overview
10 | Introduction Product Overview Network Coverage and Capacity In a simple point-to-multipoint network, an Aprisa SR+ base station can communicate with up to a practical limit of 150 remote stations. The Aprisa SR+ has a typical link range of up to 60 km, however, geographic features, such as hills, mountains, trees and foliage, or other path obstructions, such as buildings, tend to limit radio coverage. -
