Question on wireless technologies

vish

Hi element14,

 

As a part of my hobby project, I want to implement some wireless communication between my modules. When I went scouting for the parts, I became confused.

I previously know about WiFi, Bluetooth and ZigBee. But now I'm started seeing some thing called 2.4GHz modules, but can't figure out what exactly this means.

Also I saw nRF24xxx in some posts. How is this different?

What would you suggest if I want to have a data rate of minimum  200KBPS in say some 12m radius with some 4-6 walls in between? I will have some 8-12 nodes in my network that needs to be connected.

 

Thanks ahead,

vish

  • Hi Vish,

     

    The 2.4GHz frequency range is an unlicensed area used by all sorts of different radio technologies.  As you mention, Wifi, Zigbee, 802.15.4 (underlies Zigbee), and lots more.  There are other unlicensed areas in the radio spectrum.  You can find out more with your favourite search engine.

     

    Have a look at the Open Energy Monitor project.  You'll find details about some wireless chips/modules they use.  Also have a look at the TI CC1101.  It's my personal favourite.  Nordic semiconductor nrf24l01 modules.

     

    One final recommendation, PanStamp.  It is a Atmega or MSP430 based wireless radio and microcontroller system with an excellent protocol for sensor and actuator networks.  PanStamp supports web integration and interoperability with a variety of popular tools.  It's all open source, and the creator sells nice hardware modules too.

     

    Good luck,

    Lawrence
