Bell has been working on this new network together with Telus, so all the information below should also apply to Telus.
Several days ago Bell flipped the switch on its brand new GSM network (HSPA/HSPA+ on 850/1900 MHz) and surprised all sceptics: the new network offers coverage from Atlantic to Pacific to places far north (Yellowknife, Whitehorse, Labrador City), the network covers not only big cities but also many remote areas. The only area left out for now is Manitoba, Saskatchewan and Northern Ontario. In Newfoundland the new HSPA network seems actually bigger then the old CDMA 1x/EVDO network!
Coverage maps for different regions can be found at the bottom of this post.
In less than a year Bell and Telus have built a GSM network which is now probably bigger than that of Rogers! They simple installed the new HSPA hardware on existing CDMA towers plus built some new ones.
While technically minded users can point out that this is not exactly GSM but HSPA, it is based on GSM (and it also borrows some concepts from CDMA). The evolution of this technology looks as follows:
GSM => EDGE => UMTS (WCDMA) => HSPA
For the end user without background in telecommunications engineering, it looks and feels like GSM because you use exactly the same phones and smartphones as the ones sold by GSM carriers all over the world, like Nokia 2730, BB Bold 9700, or iPhone 3G, all now available at Bell.
Bell and Telus invested millions of dollars in this new network, according to some estimates in the business press, a few billion, and they didn't do it to keep paying for maintenance of both CDMA and HSPA networks that mostly overlap each other. This is most likely the end of CDMA in Canada.
If you shop for a new phone or smartphone with Bell, you need to do some investigative work, study all the frequency bands, especially if you do lots of travelling, both in N.America or overseas. Bell must have huge inventory of now mostly obsolete CDMA handsets and they will be trying to push them on unsuspecting customers for the next few months. CDMA phone is only required if you need coverage in those places in Canada where the new HSPA network is not available yet, and also in some parts of the USA, everywhere else in the world you need a GSM phone.
The following set of frequencies will get your GSM handset working mostly everywhere, but not all GSM handsets support all frequencies, so check what you really need before you buy:
GSM/GPRS/EDGE: 850, 1900 MHz - USA, Canada, parts of S.America
GSM/GPRS/EDGE: 900, 1800 MHz - everywhere else
UMTS/HSPA: 800, 850, 900, 1800, 1900, 2100 MHz
Below are screenshots with coverage maps from Bell's website, they show both old CDMA 1x/EVDO coverage and the new HSPA coverage.
