Real-time information and power exchange between components of the Smart Grid requires high-speed, fully integrated, two-way communication. S&C’s SpeedNet™ Radios can make it happen.
SpeedNet Radios vastly improve the performance of private-network utility radio systems by combining secure long-range communication, high-volume data transmission, and flexible mesh networking to provide benchmark performance for automation and control applications.
SpeedNet radios form a peer-to-peer mesh. SpeedNet Radios automatically build routing tables that define message paths; if a node is lost, a new path will be quickly established. Operating in the unlicensed 902-928 MHz band, typical range with an omnidirectional antenna is 2 to 5 miles in mesh mode, and over 6 miles in point-to-multipoint mode. If needed, SpeedNet Repeater Radios can be installed to increase transmission range and provide alternate nodes for message routing.
SpeedNet Radio frequency-hopping spread-spectrum transmissions are inherently difficult to intercept and jam. Its 10-ms dwell time on a frequency is 60 times faster than other systems, making each transmission a very small target for jamming, and much less susceptible to interference. Address filtering denies network access to unauthorized radios, and 128-bit encryption protects mission-critical data.
With their exceptional data throughput, SpeedNet Radios greatly improve the restoration speed of S&C’s IntelliTeam® SG Automatic Restoration System — the universal Smart Grid solution that provides unmatched interoperability. SpeedNet Radios improve SCADA refresh rates too.
S&C’s experienced staff has the expertise to perform the necessary up-front topographical analysis and on-site testing of the communication infrastructure. And S&C’s can provide installation and commissioning of the equipment, as well as ongoing maintenance.

SpeedNet Radios are offered in four versions:
For installation in a user-furnished enclosure, it requires a 12-Vdc power source. The antenna can be a whip mounted on the enclosure, or a remotely mounted omni-directional or Yagi antenna can be used.
SpeedNet Streetlight-Mounted Repeater Radio
In a cast-aluminum weatherproof enclosure that mounts on a streetlight arm. Extends communication range and expands network area. Can be powered from a photocell socket or 110-240 Vac, 50 or 60 Hz; includes battery back-up. A whip antenna is mounted on the bottom of the enclosure.
SpeedNet Utility-Pole-Mounted Repeater Radio
In a padlockable plastic weatherproof enclosure that mounts directly on a utility pole. Extends communication range and expands network area. Powered from 110-240 Vac, 50 or 60 Hz; includes battery back-up. Antenna can be a whip mounted on the enclosure, or a remotely mounted omni-directional antenna can be used.
SpeedGate™ Radio Interface System
SpeedGate™ Radio Interface System. In a padlockable plastic weatherproof enclosure that mounts directly on a utility pole. Includes provision for a gateway communication device, permitting data exchange with a different communication system. Powered from 110-240 Vac, 50 or 60 Hz; includes battery back-up. Antenna can be a whip mounted on the enclosure, or a remotely mounted omni-directional or Yagi antenna can be used.
SpeedNet Radios cannot communicate directly with other types of radios because of differences in frequency selection, spread-spectrum frequency hopping patterns, channel use, and network management algorithms. A SpeedGate Radio Interface System, with an appropriate gateway communication device, is required in such instances.
