The 315-megahertz (MHz) versions of the company’s ultra-low power radio modules are available. The development enables integrators to install wireless sensor networks into buildings using a frequency band that is far less crowded than the others available, such as 2.4 gigahertz (GHz), says the company. According to the manufacturer, the 315-MHz frequency band is able to carry data through materials, such as building walls, more efficiently than the higher 900-MHz and 2.4-GHz frequencies, and 315-MHz radio frequency modules yield longer indoor range, (up to four times the range of 2.4-GHz data communications) when other range variables are held equal. The radio modules are available in a development kit that also features the company’s energy harvesting technologies. Integrators can get radio modules, a pair of energy harvesters (solar and mechanically powered), and other components that allow them to explore sensor networking options that do not rely on line or battery power.
