These are very popular 2.4GHz XBee modules from Digi (formally known as Maxstream). These modules take the 802.15.4 stack (the basis for Zigbee) and wrap it into a simple to use serial command set.
This is long range high speed serial wireless communication module which can give range of 30 meters indoor or 100 meters outdoor. This module is ideal for robot to robots or robots to PC communication. This ZigBee wireless device can be directly connected to the serial port (at 3.3V level) of your microcontroller. By using a logic level translator it can also be interfaced to 5V logic (TTL) devices having serial interface. This module supports data rates of up to 115kbps. It has indoor range of 30 meters and outdoor RF line-of-sight range of up to 100 meters.
