New moto digital radios (not astro or DTR)

[grem467]

Motorola has developed a TDMA based radio geared for the business user:

doesnt support encryption, but since its TDMA based, and who knows what vocoder they used, i wonder if we will EVER see a receiver that can listen in.

Hello friend:
Why can't one listen to this system,no scanner can??

Looks like it's a European thing...?

 

[grem467]

no, its for the US, they are targeting businesses that need repeaters and would like digital, but cannot afford typical astro type gear.

Scanners do not support TDMA, and motorola isnt talking about what vocoder they are using with this. I suspect its AMBE over TDMA, but i would think they would just call it iDen if that was the case.

Time will tell

Motorola have set up a TETRA system here in Australia though they aren't calling it TETRA in any sales blurbs. I believe you will find that they are marketing more TETRA product as time goes on- these products look awfully like TETRA to me and, no, you can forget about scanning them.

yeah i forgot all about tetra.. im sure they didnt reinvent the wheel with this one.

From my understanding.

1) They are not TETRA
(Or Dimetra, which is Motorola's brand for their TETRA product)
2) They are based on a European Standard (different from TETRA)
(There may be some technical similarities, as is common between different standards)
3) They are being sold in the US
4) They are targeted at non-public safety users.

My Guess

A scanner will be developed when a market exists that is willing to pay the price for development (and any licensing) providing a company believes the product can be technically built to satisfy that market. :twisted:

N Jay,

Whether these radios comply with the TETRA standard or not is not as important as the fact they are based on TDMA, as is TETRA. There are significant similiarities between these radios and TETRA, and it seems rather odd that senior Motorola staff who I have spoken to do not attempt to dispell any talk that they are "TETRA".

It is a FACT that Motorola are actively marketing TETRA here in Australia along side their APCO line of products. If Motorola is nothing else, they certainly are pragmatic.

That they don't dispell any talk doesn't have to mean anything but if you check the Motorola link in grem467's post you will see that the MOTOTRBO radios are based on a standard different than TETRA.

As such I disagree that it is important that both standards are based on TDMA - GSM for example is also TDMA-based, and so are many other technologies, including non-radio ones. In fact one might think TETRA borrowed heavily from GSM, and you probably wouldn't be that wrong.
So even there is some relation between the technologies and/or standards it doesn't imply any compability or that they are one and the same. In fact I don't see a need for any vendor to dispell any talk if they state their radio is based on standard A, because that (normally) means it's not based on standard B, C, D ...

It is a FACT that Motorola are actively marketing TETRA here in Australia along side their APCO line of products. If Motorola is nothing else, they certainly are pragmatic.

Motorola only markets TETRA where they have to, i.e. where the tender specifications / technical requirements insist on the same. Otherwise they promote their proprietary systems (typically iDen outside of the US).

 

[N_Jay]

Motorola markets P25 in all markets and TETRA in Markets where TETRA is a viable and legal offering.

Why the surprise.

Other than that Racoon is right.

A standard is a standard and it really is not important what it is "Like" because it is either the standard or it is not.
