Vertex TDMA?

[rescuecomm]

Vertex Standard has announced that they will begin making TDMA 6.25 Khz bandwidth digital radios. Are these going to be using the Nexedge technology that Kenwood and Icom have? Or is this going to be another proprietary radio protocol?

 

[Citywide173]

Considering Vertex is now owned by Motorola, I doubt you'll see Kenwood or Icom willing to license it.

6.25 kHz or 6.25e ????


If it is TDMA, I would guess 6.25e.

Where did you see the announcement?

Vertex Standard Announces Digital Radio Launch Plans -- TOKYO, March 9 /PRNewswire/ --

Full details there. Due in late 2010 with TDMA DMR standard Mobiles, Portables and Repeater. The article states 6.25kHz although it's likely that it will be two-slots in 12.5kHz.

Confusingly, members of the DMR association include both TDMA and FDMA manufactures. However the ETSI DMR Tier II standard specifies TDMA.

Icom and Kenwood are also part of the dPMR standard with a few other peripheral hardware manufactures. Personally I believe TDMA will emerge as being the front runner for a widely accepted standard.

In related news, HYT & Simoco have also joined the DMR association.

The article state "6.25 kHz equivalent"

Then it is MotoTRBO (like).
We will see how the compatibility works out when we have a few brands to choose from.

If we're being pedantic, it actually says "....based on two-slot Time Division Multiple Access (TDMA) 6.25 kHz efficient digital technology..."

But we're not, so it's OK:lol:

Interoperability is a key issue of the DMR working group so one would imagine that compliant brands would use the same standard. Hopefully they will have a similar approach to DMR Tier III as they did with MPT1327 with multiple vendor interoperability at every level.

I suppose we will have to wait and see for the definitive answer.

Oops! Brain Fart!
Eyes read efficient, and brain received equivalent.

It will be MotoTRBO compatible. In other news, HYT has introduced MotoTRBO compatible radios and repeaters as well. Some features are proprietary to Motorola (text messaging, etc), but the voice is 100% compatible. You can use Motorola radios and HYT radios on either a Motorola or HYT repeater to talk to each other.

Info on the new HYT brand there and the new portable respectively. There products look very pleasing to the eye.

*squinting*

Ah see! Is made in China! Must buy at Walmart!

Do you have a link supporting the Vertex/mototrdo info?

I am sure we are all hoping the Digital Mobile Radio (DMR) Association assure compatibility (and to extend the assumption, compatibility with MotoTRBO) but that is not said explicitly.

It will be interesting to watch.

I would assume that since Motorola owns Vertex, that any DMR solution Vertex puts out there would be Motorola compatible. But it is Motorola, so you never know.

In a related issue, Hytera (HYT) has a new portable, mobile, and repeater that are all MotoTRBO compatible for voice. I have been told that the data functions are not the same, but you will be able to talk between HYT and MotoTRBO radios.

I believe DMR members will be holding more practical interoperability tests soon ahead of the release of DMR Tier III Trunked systems at the end of the year.

UPDATE:

Found this today. They had it at IWCE last month but I forgot about it.

The mobiles and repeaters are linked off of that page. Anything look familiar?

 

[W2NJS]

Minor, very minor, physical differences between the Vertex TRBO HT and the Motorola. Different knob shapes, a hex-shaped main button rather than Motorola's round button, but otherwise hard to tell from the Motorola unit.

 

[davidgcet]

yep, and take the same battery and other accy as Moto units from what my supplier told me. i have not ordered my set of them yet, but i am supposed to order them soon.
