Telit Wireless Solutions has launched the LT70-868 terminal and the LE70-915 module, both point-to-point, star-topology, short-range wireless products aimed at the multi-kilometer range wired-to-wireless network migration market. According to the firm, the products' high sensitivity, link budget and data rates are geared for applications such as solar and wind farms, oil and gas and agricultural automation.

The terminal and module operate respectively in the European 868MHz and North American 915MHz ISM licence-free frequency bands, allowing manufacturers to quickly integrate wireless communication into control systems and sensor nodes replacing wired networks with wireless data links meeting full regulatory compliance.

The LE70-915's 142dB radio link budget makes integration with the host hardware simple, lowering BOM costs. LT70-868 terminal also delivers a high 144dB link budget. Both products are rated for continuous 500mW configurable radio output power operation combined with high sensitivity (-117dBm), delivering a reliable operating range of up to 10km. And the ultra-low standby current allows use of the devices in battery powered electronic designs for applications such as soil moisture and pipeline monitors, hall-effect closure detectors and PIR surveillance devices requiring battery replacement cycles in multiples of years. Both the terminal and module have single-digit micro-amp standby currents.

The compact module is housed in a 26 x 15 x 3mm LGA package, the terminal in a 100 x 66 x 46mm rugged IP67 metal enclosure and are capable of sustaining data rates up to 57.6kb/s, providing customers an array of application possibilities. The AES encryption feature allows the products to be applied in devices and systems transmitting sensitive data. As a member of the Telit Short Range module family, the LE70-915 is fully form-factor compatible with all its ZigBee, Wireless M-BUS and Low-Power Mesh counterparts.
