Galaxy – One Platform, Multiple Applications
Galaxy is the name of Telematics Wireless' family of Wide Area Communication Networks applied to various IoT aplications. It operates on the licensed frequency in 450-470 MHz band and utilizes a single Base Station for wide area coverage with tens of thousands of managed wireless nodes interfaced with various devices. Wireless repeaters can extend Base Station's communication range and enable coverage of the "dead zones".
Utilizing the same communication infrastructure and various types of sensors and actuators, Galaxy applications include Streetlight Control, Water Resource Management, Advanced Metering Infrastructure, ITS and others.
Our unique features:
Minimal infrastructure in the streets
Galaxy's unique feature is the minimal infrastructure required to cover large areas. Unlike most competing solutions, Galaxy does not require a large number of Concentrators and Gateways. With an average coverage radius of about 10km in urban terrain and up to 30km in rural terrain, Galaxy Base Station with a single antenna communicates directly with up to 50,000 wireless nodes. Augmented with small wireless repeaters for coverage of dead zones and range extensions, Galaxy is the most reliable and cost effective solution available today for immediate deployment. In certain areas where Galaxy reach may be limited, another Teematics' system utilizing extremely robust RF Mesh technology may be deployed. Thus unique combination of wide area Galaxy and "local" cluster type RF Mesh will provide the optimal and unmatched solution for any municipality.
A zero hierarchy (“Star”) control system
Galaxy utilizes a robust “Star” topology, which is especially suited for a relatively large number of end points within the coverage area. The “Star” topology avoids inherent Multi – Hop availability and latency issues often encountered in Mesh solutions, by creating a direct link between the base station and the end unit thus improving system availability and reducing interdependency (increased fault isolation) among the network nodes – an important feature for a critical service. These characteristics make the Galaxy Star topology the ideal solution for a large scale deployment containing thousands of end points that must be controlled and monitored individually.
A correct choice of wireless media
It is not only availability and cost effectiveness that makes T-Light Galaxy the optimal choice for wide area control and moitoring. Unlike the majority of competing wireless M2M systems that utilize unlicensed frequency bands, Galaxy operates in a licensed frequency band. No more operating in highly congested, interference-saturated frequency bands with regulation-limited low power output. Unlicensed bands are dedicated for short range communication and their utilization for wide area coverage is not only complicated, but may not be reliable enough for applications requiring high communication reliability and robustness like control of critical municipal infrastructure.
Galaxy’s operation on a licensed frequency with exclusive dedicated frequency channels and increased transmission power ensures extremely reliable and uninterrupted communication over long distances. Due to the specific nature of applications that do not require large amounts of data to be transmitted to and from the end device, very narrowband channels are sufficient for Galaxy operation thus making the licensing cost negligible compared to the significant financial advantage of Galaxy deployment, operation, and maintenance.
