XBee-PRO XSC


Vendor's Description: 


This tiny Xbee 900 rf module is supposed to have a range of 15 miles. We all know that these specs are always best case scenarios that are not attainable in the real world but it probably means that we could get 9 or 10 miles out of it. I can just imagine the projects that could be possible with this type of range!

"The XBee-PRO XSC OEM RF module is a 900 MHz wireless solution designed for maximum range within the XBee® footprint. Capable of point-to-point, peer-to-peer and point-to-multipoint networking, the XBee-PRO XSC is ideal for solutions where RF penetration and absolute transmission distance are paramount to the application."

never understood what these XBee product were for.

A basic application : A serial connection without the cable. Stick an XBee transciever on your PC (RS232 or USB) and another XBee on your robot and there can be a serial link between the 2 devices. On some, that is enough to program with, others it is just a means of getting data and commands back and forth.

A medium application : having a couple serial links going on at the same time :  a robot transmits data and recieves commands on one XBee, while sending back a low frame rate video stream on another. Both working at the same time since each XBee module can be given an individual identifying number so it's data won't be confused with the other operating on the same frequency.

A more advanced application: multipoint communication: Several XBees can communicate between each other, forming a small network. This can be a sensor network or even several robots in a swarm working together. The networking is built in. 

A basic, plain vanilla radio module give no differentiation between itself and another like it, if one is communicating, it can interfere with others nearby and no error correcting or compensation done on them, like the XBees have. Additionally, the XBee modules radio section has been highly tuned for better output and reception. 

wow thanks ! now thats a good explanation ! finaly understood what they are for.

This is not a robot. Get a blog!
Every time you post a component it goes to the front page
My bad. Sorry :P
And a pretty cool component, yet another toy I'll have to try, some year.
