COMMUNICATION TECHNOLOGY
How does G7 Bridge communicate with my personal monitoring device?
G7 Bridge communicates with G7x or Loner 900 devices through an industrial quality
900 MHz radio link. Personal monitoring devices can operate up to 2 km away with
limited obstructions from G7 Bridge.
NOTE: Terrain, foliage, and buildings can reduce the overall 900 MHz radio link range.
How does G7 Bridge communicate with the Blackline Safety Network?
One G7 Bridge can link up to ve G7x or Loner 900 devices to the Blackline Safety
Network through the Iridium satellite network or 2G/3G cellular data.
G7 Bridge is equipped with an internal Iridium satellite radio and antenna that facilitates
communication when outside the range of cellular networks. The transition between
satellite and cellular is automatic and seamless.
When mounted to a vehicle, all-terrain vehicle, snowmobile or boat, G7 Bridge must
remain out in open sky, a minimum of 10 meters (33 feet) away from any buildings. This
will help ensure an unobstructed view to send and receive signals to satellites.
