Detailed Description

The Dexter Industries NXTBee sensor brings the Digi XBee radios to the LEGO® MINDSTORMS® NXT! Wireless communication between NXT's. These high-speed long-distance radios allow your NXT to communicate with any other device with an XBee radio. The XBee 802.15 communication protocol is the standard for robots everywhere.

The XBee radio system is a versatile communication solution for the Mindstorms NXT system. The performance of the NXTBee greatly exceeds Bluetooth, infrared, and other forms of communication currently available for the NXT.

Communicate Farther: The NXTBee can send information up to 300 ft and the NXTBee PRO up to 1.2 km. That's 10 times farther than bluetooth or IR.

Communicate Faster: The NXTBee utilizes the NXT's high speed RS-485 line for high speed communication.

Communicate Wider: The NXTBee uses the XBee protocol which includes point to point networking and mesh networking.

Mesh: One of the most exciting aspects of the NXTBee is its ability to mesh network. Mesh networking is the ability of devices to "mesh" together. NXTBee automatically finds other XBee radios (other NXTBee's or devices using XBee's) and can relay information to them and between them with no setup: they do it automatically. XBee radios pass on data and information from other XBee's, allowing further and more reliable information to be passed. You can create a whole network of 65,000 different devices talking to each other!
