PCS article response

Tom:

I just read an article at http://www.privateline.com/PCS/

mobilephonepictures.htm, which I assume you wrote. As far as I am aware, the last IMTS/MTS mobile system left in North America is run by Bell/Aliant Telecom in Newfoundland, Canada. This system is also slated to be de-commissioned in August of 2002, thereby ending a long history of this technology. In conversation with a past IMTS supplier, Glenayre, a few years ago, they indicated that the only other IMTS system that they were aware of still in operation was in Asia (Cambodia or somewhere). Naturally, I stand to be corrected on this info.

In Newfoundland, our mobile switch is a Glenayre GL1200 (6 side by side units) and the mobile units used were mostly a combination of Novatel VTR74, VTR84, and VTR2084 radios, Glenayre GL2020, 2040, 2021, and 4040 units. Being a landscape with some remote areas difficult to service with cellular, the old IMTS will be missed by some users.

Editor's note. You can read the paperwork Aliant filed to decommission this service by clicking here. It is in Word format.
