View Full Version : GPS tracker CAT M1

05-03-2019, 10:22 AM
I've been keenly eyeing GPS trackers and it appears the new CAT M1 capability is the way to go. In particular the TK319-L from Ebay/Aliexpress looks appealing.

Spark offers CAT M1 reaching 98% of the population. They say an expected 2000 devices will be added to the (IoT) network every week.

What's great about CAT M1 over conventional 4G is the power saving. A device battery could potentially last 10 years. Then there's the signal penetration advancement. A signal can penetrate buildings like never before. Also the theoretical range of signal is 62 miles (100km). It seems the whole package has been re-engineered so it's frugal on resources including data bandwidth.

So far almost no-one I've talked to has even heard of it. Indeed I only discovered it a few days ago and have been studying the subject since. Thanks to Mr.Google.

Is a special 4G SIM required or will any 4G do? Is there any good or bad experiences with CAT M1 devices or service providers out there? Is Voda's nb-IoT a better bet? Keen to hear any thoughts, tips or comment. Thanks.

OK, so there's another question.. will I need data only on the SIM or will I need sms and voice as well?

I enquired with Skinny. No, they don't support CAT M1. Even though they resell Spark, their bundle doesn't include it.

Here is a list of things the SIM needs: A. support SMS GPRS. B. NO pin code,no password,no voice mail box. C. support caller ID display.

We got a similar thing, its a GPS tracker, All it needs is a Standard SIM card, any pre paid will do, with some credit ;).

What you do is if you want to see where its located all you meant to do is text the Sim number with a code, a few minutes later a map appears on your phone showing its location.

That's how its meant to work, haven't tried it yet. You have to wire it into a 12V power source on the car that's always live, Either directly to the battery or most cars have a live feed somewhere, most will have plugs in the fuse box. This way, its always on and tucked up out of site someplace.

Curiosity got the better of me LOL :D, put in a SIM, and used clothes pegs to connect to Battery ( testing only) sent a text -- Within a minute got a Map / location back, Damn accurate, within approx. 1Mtr of where the cars sitting.

Thanks Wainui. Super cool!

That's a nice little tracker at a good price. Very popular. There's a lot to like about it.
Possibly I could get one in the interim and wait for the 4G CAT M1 tracker to be a bit more tested and proven. Reading some good write ups about CAT M1. Supposedly a good step forward in a number of areas.
