ELOS packet data networks have a cellular structure and provide real-time communications
at ranges up to 50 miles. This extended range of communication is by diffraction
around the curvature of the earth, atmospheric diffraction and tropospheric propogation.
A typical ELOS network is shown below. The network can be as small as one base station
or may be comprised of thousands of base stations, repeaters and remote stations.
ELOS networks are used for position reporting in mobile applications (AVL), fixed
site data collection (SCADA) and two-way text messaging.
MeteorComm’s ELOS patented communication protocol combines CSMA (carrier sense
multiple access) and TDMA (time division multiple access) for achieving a channel
utilization greater than 90%, with minimum contention.
An ELOS network uses only one type of VHF transceiver, either a
MCC-545B or a MCC-545C.
Each of these packet data radios are software programmable and can be dynamically
configured to operate as a base station, a repeater or as a remote station (mobile).
Combined with the ELOS protocol, a network of thousands of stations can be efficiently
operated on a single frequency with minimum logistics because all radios are programmable
and interchangeable.
The following features are embedded within an MCC ELOS Network:
Robust Packet Switched Network
- Automatic roaming and connectivity
