LoMesh Data Modem

LoMesh is a LoRa technology based data radio solution, which provides transparent serial interface to communicate with multiple devices over a multi-hop mesh network. With the robust spread spectrum modulation technique of LoRa, this radio can achieve reliable communication in noisy and harsh environments. LoRa spread spectrum modulation allows the radio to operate with high sensitivity and long range with high immunity to RF interference.

The modem operates over the 868 MHz & 915 MHz license free Industry Scientific and Medical (ISM) frequency bands. Modem comes with a complete LoMesh wireless meshing stack with easy AT commands to configure it and transparent mode software, reducing the development time during project development and deployment. With RS485 interface, the modem can virtually interface with any device that has a serial port. Modems come factory provisioned for guaranteed out of box connectivity with options to modify configurations.

Parking Management System

Each parking space is equipped with a battery powered occupancy sensor that can detect the absence, arrival, presence, and departure of a vehicle. The sensors are self provisioning, with a unique MAC address assigned to each unit that is associated with its serial number and bar code. When an occupancy sensor detects vehicle activity, its embedded LoRa transceiver sends a short message packet containing the change in status to any wireless Internet gateway within its range. The gateway can be part of a private LoRa network or a node in a public LoRaMesh service provider

The gateway forwards the packets to Parking Cloud Service application that can reside either on a Cloud-based or dedicated server. This turnkey parking management solution uses the sensor's messages to keep track of open and occupied spaces. It can present parking events on a web interface, and provide parking data to third-party applications that generate billing information, and advertise available parking spaces to motorists via their smartphones or other wireless devices. It can also be customized to support a wider range of specialized services. The LoMesh Protocol supports bi-directional communication allowing the parking manager to query the sensors to find available/occupied slots.
