Sub-1 GHz Wireless Solutions

We offer low-power, sub-1 GHz wireless solutions for use in a wide range of applications. These high-performance, bi-directional radios operate over a wide frequency range, including 315, 433, 470, 868, 915, 928 and 960 MHz in the license-free industrial, scientific and medical (ISM) frequency bands, based on proprietary modulations as FSK/GFSK/OOKn/MSK.

See examples of our MCUs and communication ICs for metering applications supporting multiple standards and proprietary protocols such as:

• Smart Energy software solution for the OL2385 wireless microcontrollers include Zigbee Golden Unit, Zigbee PRO and Zigbee Smart Energy application profile SE v1.4.
• Wireless Meter-Bus (M-Bus) are becoming key standards for connecting meters to the grid and to home energy management systems. Wireless M-Bus defines the bi-directional communications between meters (gas, water and electricity) and data concentrators. Based on EN13757-4, Wireless M-Bus supports two types of readout systems – a walk-by/drive-by method requiring more frequent transmission addressed by the T mode and the networked method with R and S modes.
