Wireless mcus power CEL’s first Sub-GHz modules

Powered by SiLabs' Si10xx wireless mcus, the MeshConnect Sub-G modules are CEL's first module series optimised for wireless applications in the sub-GHz ISM band. This includes smart meters, home automation, security systems, remote keyless entry, irrigation control and weather stations. According to SiLabs the MeshConnect Sub-G modules are designed for dense operating environments and deliver 'superior' rf range and performance. The 868MHz and 902-928MHz frequency ranges are designed to provide robust transmission for non-line-of-sight applications. The modules are said to achieve a link budget up to 140dB with a sensitivity of up to -121dBm. Higher link budgets enhance wireless system performance in challenging operating environments. SiLabs claims the single chip Si10xx wireless mcus provide industry leading low power consumption, enabling extended battery life for wireless systems based on MeshConnect modules that require battery backup or fully portable operation. The wireless mcus also enable the modules to deliver ultra low rf power consumption. The MeshConnect Sub-G modules support software platforms such as Synapse SNAP embedded firmware, wireless M-Bus, Silicon Labs' EZMac software and CEL's proprietary application programming interface. The modules also provide a 1 MB flash memory option to support over the air programming. Rich Howell, director of business development at CEL, said: "Silicon Labs'Si10xx family provides the optimal transceiver/mcu platform for our MeshConnect Sub-G modules. By collaborating with Silicon Labs, we are able to deliver CEL's first modules in the sub-GHz frequency range to support longer range wireless communications."
