Cellular Shield frequency question

Projects Programming

Hi,

I have purchased a cellular shield from sparkfun: http://www.sparkfun.com/products/9607

I am working through this tutorial: http://tronixstuff.wordpress.com/2011/01/19/tutorial-arduino-and-gsm-cellular-part-one/

I am stuck at this part "The next step is to tell the GSM module which network frequency(ies) to use." I am using a Rogers SIM card in Canada. How would I find out which network frequency to use?

Does anyone have any experience with setting up this cellular shield with Rogers in Canada?

The PDF which is mentioned in the tutorial has this chart on page 127:

value description

0 GSM900
1 DCS1800
2 PCS1900
3 GSM850
4 GSM900&DCS1800
5 GSM850&GSM900
6 GSM850&DCS1800
7 GSM850&PCS1900
8 GSM900&PCS1900
9 GSM850&GSM900&DCS1800
10 GSM850&GSM900&PCS1900

Thanks!

  1. Google --> canada gsm frequencies
  2. Result no. 1 --> GSM frequency bands (Wikipedia)
  3. Browse through the article --> GSM frequency bands - Wikipedia
    "In Canada, GSM-1900 is the primary band used in urban areas with 850 as a backup, and GSM-850 being the primary rural band."

Try them one by one, until you get +SIND: 4 instead of +SIND: 8

Hello,

Many thanks for taking the time to answer. I didn't think of wikipedia. It looks like it has all the info.

Sure, no problem!
Just a quick reminder that search engines can do good for people :wink:
