I've just had some one ask me if CDMA modems are availble for the Telecom network. (By modem, I mean a stand alone device with a RS232 interface.) The Sierra Wireless website shows AirLink devices, but I can't find any indication that they're available in NZ.

I was a geek before the word was invented!

Contact APT, I know they had a slew of devices a while back, some even support SMS.

Is this the sort of thing you're after?

USB Modem Stick, it's actually a Sierra Compass 597, here's the product page.

Hope this helps.

Sorry just saw that you want standalone with RS232, I re-tract my previous post!

There's nothing that I know of in the market that would suit your needs available (well not that I know of!), I'll have a dig around and see what I can find.

In the dim dark past I've developed (linux) SMS software to drive one of these:

but it got dumped when we moved to Vodafone, and were able to use a much simpler device which was supported by smsd (from Siemens, an MC35i from memory).

The Anydata was a bizarre device, perfectly functional, but didn't follow any AT command set standards.

The annoying thing is I still have one somewhere but I have not seen it for a couple of years.

Check with them for the DTM-500 module

http://cdma.co.nz/solutions/mobile_data/oem_modules/anydata_dtm_500d

I seem to recall there also existed a WCDMA/gsm drop-in replacement too.

Again from memory, the command set was custom though I quite liked the read and delete command, one command and it responded with the data and deleted the SMS from the module straight away, much easier than having to do inbox management remotely.

Thanks very much for this. I hadn't noticed the lack of AT command support.

I know the Siemens well, but a friend has a client who wants to use CDMA.

APT have an application called MySMS which was written to drive the SMS interface on the modem. I am sure they will help you out if you buy a modem off them

No problem. It's not a lack of AT, just an obscure command set.

We want to use it as a normal modem, i.e. connect to a remote modem and send data using Hayes AT commands, and also send SMS messages. Will it do this out of the box?

I've used a Hantel HTT-800 from APT as a replacement to an old Motorola 025 device. Its used in a weather station in the middle of nowhere to allow boaties / pilots to ring it up and get a weather report. The only problem I had with it was its ring voltage. They are designed for newer telephony devices that can live with a lower (circa 50V off the top of my head) ring voltage. I got a ring voltage booster from a company in Chicago (Mike Sandman) to boost the voltage. Works mint.

(except now the voice module of the weather station has poo'd itself and needs replacing but can't cause all the gear is obsolete but thats another story...)

APT are (probably) the best for CDMA FWT's (e.g Hantel HTT-800) but other sources are -

ORB - Tellular SX5T -

NiceGear have the 2N Smartgates - these are a GSM FWT
http://nicegear.co.nz/gsm-gateways/2n-smartgate/

We had a 2N in our office PBX for ages to make office-to-GSM calls equivalent to GSM-GSM but now the boss has gone back to Telecom...

Hope i've been a little bit helpful

I'd GIVE away my Anydata but I just cannot find it, nor can I find my coveted modified Nokia 6235 either.

You'd probably be best looking towards WCDMA 900/850 solutions now as that is the way it's all heading.
