Solving the LTE uplink problem
LTE is designed for data consumption at the endpoint. But in mining, it’s at the endpoints (the mining fleet) that the data is created and needs to be uploaded to the network. LTE has physical challenges that limit this capability. One of these limitations is in the number of transmit antennas available to the LTE client.
While multiple antennas are available for receiving data from the network, only a single transmit antenna is available. On a haul truck, where the best balance of visibility and reliability is achieved when antennas are placed on either side of the truck, a single transmit antenna leads to a significant problem with antenna blockage, at least half the time.
The Osprey is designed with an integrated RF switch that allows the Intelligent Endpoint (IEP) to transmit on whichever antenna has the greatest signal quality. The transmit antenna is selected in real-time, ensuring the IEP is always using the best antenna. This unique solution allows the Osprey to ensure the device is not only receiving communication from the network, but the critical data created by the onboard applications is received at the server.
