The wireless communications unit is protected by robust industrial housing that also features a series of standard connectors and a sim cardholder. Being a standalone device, this plug-and-play solution, comes equipped with standard connectors for power supply, antenna, serial port, and handset. On account of its focus on gsm communication, and its robust casing, the tc35i terminal is particularly suited for m2m applications with a low data transfer volume. This makes it a product that can be employed in a wide range of business fields – metering, remote maintenance, transportation and logistics, traffic systems, vending machines, security, and facility management.
