[http://www.linxtechnologies.com/ Linx Technologies] makes several low power RF transmitter/receiver chips. Their range is around 500' - 1000'. They are geared for one way communication only, like keyless entry systems. They also make several serial encoding chips that make the wireless communication more secure/crack proof. Their latest chip, the HS series, is based upon the SkipJack algorithm developed by the NSA. BBA broadband ampifier modules are available for boosting the signal power to 17dBm when combined with the HP-3 modules and FHSS techniques. | [http://www.linxtechnologies.com/ Linx Technologies] makes several low power RF transmitter/receiver chips.

− | + | [http://www.maxstream.net XBee/XBee Pro modules] Modules are a drop in Zigbee module. Modules have a UART style interface with an AT command set. Cheap and very popular, these modules are great for serial cable replacement or remote sensor monitoring. | |
[http://www.sparkfun.com/commerce/product_info.php?products_id=8469 Sparkfun Bluetooth Module] Dropin module with a complete Bluetooth stack. Modules also have a UART interface with a AT command set. An advantage is many laptops and cellphones have a Bluetooth transceiver builtin. | [http://www.sparkfun.com/commerce/product_info.php?products_id=8469 Sparkfun Bluetooth Module] Dropin module with a complete Bluetooth stack.
