Features:

Available for licence-exempt operation in the UK 173MHz bands, the TX1 & RX1 modules combine

effective screening with internal filtering to minimise spurious radiation and susceptibility thereby

ensuring EMC compliance. They are particularly suitable for one-to-one and multi-node wireless links

where longer ranges are required at low to moderate data rates. Applications include building security,

EPOS and inventory tracking, remote industrial process monitoring and data networks. Because of

their small size and low power consumption, both modules are ideal for use in battery-powered portable

applications such as hand-held terminals.
