RF wireless modules deliver high output power, increased data rates 

MURATA DNT Series wireless modules enables a decreased total cost of ownership because it helps to minimize the necessary infrastructure equipment. Devices incorporate frequency hopping spread spectrum (FHSS) to deliver better immunity to interference, which is critical in the more crowded bands such as 2.4GHz WiFi. Products provide longer ranges for outdoor functions, up to 40 miles for 900MHz installations and 10 miles for 2.4GHz line of sight. Devices are configurable with high RF data rates – up to 500kbps in both 900MHz and 2.4GHz bands for data intensive applications in need of lower latency. Product gateway and separate and secure LANs with 128-bit AES encryption help streamline facilitation with local enterprise networks.  http://www.murata.com
