Astro 25?

[jlanfn]

The Wiki is very unclear about what the term "ASTRO 25" can be applied to. I know it refers to Motorola's P-25 products, and it is used on their website for both trunked and conventional P-25 systems. But can P-25 audio on a Motorola SmartZone 4.x version (3600 baud control channel) also be considered "ASTRO 25" audio, or does "ASTRO 25" in trunking apply only to SmartZone 6.x version (9600 baud control channel) systems?

 

[ILMRadioMan]

ASTRO 25 can only be applied on 6.x or 7.x systems at this time.

And it is for that very reason (control channel baud)

Other radios are capable of "Astro" audio (I.E. conventional or digital trunked in a 3600 cc) but those are basically considered using the IMBE vocoder on a system where it isnt neccessary.

However, for it to be considered an Astro 25 (P-25) system, it MUST use the IMBE vocoder.

ASTRO 25 can only be applied on 6.x or 7.x systems at this time. . . . . .

Ahhhhh . . . . WRONG! (Yes, I know, "I'm obnoxious", it's just me style"

Astro25 is Motorola's BRAND NAME for their P25 products and systems and includes many related features, functions, equipment, systems, and configurations.

SO . . . . .

It would depend on how and where it is used to try to determine what it means, and like any BRAND NAME, the company using it is the only arbitrator of what it means, and when it can be used,

AND . . . . .

That meaning and usage can and does change over time, and may not be consistent or logical.

IN ADDITION, . . . .

"Accidental" incorrect use by the company can be allowed further weakening any relationship between the BRAND NAME and the products, services, system, features, functions, equipment, and configurations, it is applied to.

SO, . . . . To tell someone what it means in definitive terms, without context, and to state such as fact is WRONG.

Right now they seem to be focussed on the "network" and everything connected to it.

 

[ILMRadioMan]

You are correct.

Hence why I said, "At this time"

Unless "at this time" you can tell me that Astro 25 applies to something else other than 6 - 7.x?

 

[N_Jay]

HPD data systems for example.

AND

New portables operating on 3.x and 4.x systems.

 

[ILMRadioMan]

And let me add that there are the AMBE, etc.. Vocoders that apply to P25 as a whole.

However, we are only talking ASTRO 25 here.

So please keep that in context.

 

[ILMRadioMan]

HPD data systems for example.

No.

Those are not Astro 25.

They are Type II trunking systems using the vocoder to use digital voice on a system.

But they are not Astro 25.


And for HPD...do they not use the 6.x / 7.x backbone / technology?

 

[ILMRadioMan]

I will give you they are "P25".

But not ASTRO 25.

And even then they are not P25 trunked systems. Just systems using the vocoder to applt digital voice.

 

[N_Jay]

No.

Those are not Astro 25.

They are Type II trunking systems using the vocoder to use digital voice on a system.

But they are not Astro 25.

ASTRO® 25 Network Portable Radios - Motorola USA

And for HPD...do they not use the 6.x / 7.x backbone / technology?

:lol: Sure they do, but if it is an all data network then there is no vocoder.

Astro25 means whatever Motorola wants it to mean ant any particular time.

Next you will be trying to nail down MotoA4

[ILMRadioMan]

Good point, I retract my vocoder point.

Minus that point, I think we are trying to say the same thing.

However, I think to the same point, you cant label a 4.x system an ASTRO 25 sytem...for that very reason: Motorola only lavels 6.x and 7.x Astro 25.

 

[N_Jay]

I will give you they are "P25".

Nope. 3.x and 4.x systems, even systems that used P25 CAI on teh voice channels are NOT P25 trunking systems. (They were as close as you could get for a period of time.)

But not ASTRO 25.

You error is in TRYING TO DEFINE what a BRAND NAME means, not in the definition itself. Get it?:roll:

And even then they are not P25 trunked systems. Just systems using the vocoder to applt digital voice.

Again, you are using the vocoder to make a distinction. HPD has no vocoder.

 

[ILMRadioMan]

Read above smarty pants

 

[ILMRadioMan]

4.x can handle P25 voice, but is not a "P25" trunked system - Agreed

Motorola only labels 6.x and 7.x technology (voice or no voice) as Astro 25 - Agreed

You are a smart ass - Agreed

Vocoder does not equal Astro 25 - Point made

 

[ILMRadioMan]

However, I do pose this question:

Is there a piece of end user HPD equipment that does not come with a vocoder in it?

 

[N_Jay]

Good point, I retract my vocoder point.

Minus that point, I think we are trying to say the same thing.

Nope.

However, I think to the same point, you cant label a 4.x system an ASTRO 25 system...for that very reason: Motorola only lavels 6.x and 7.x Astro 25.

No, my point is YOU can't label anything ASTRO25, only Motorola can.
AND,
Motorola CAN label ANYTHING they want as ASTRO25.

The OPs question is created by people trying to over-apply and miss-apply technical meaning to brand names, rather than understanding them as brand names and moving on.

The base station, the mobile modem, the mobile terminal, etc, etc. etc.

 

[ElroyJetson]

I see it very simply as Motorola's family product identifier for the second (and third) generation digital radios which are fully P25 capable.

[ILMRadioMan]

The base station, the mobile modem, the mobile terminal, etc, etc. etc.

I see you arent playing friendly anymore.

Thanks anyways.

 

[N_Jay]

I see you arent playing friendly anymore.

Thanks anyways.

Why do you say that?

You asked a very specific question, and I gave you a very specific answer.

Of course, my definition of end user might be broader then yours, so if you meant ""subscriber terminal Equipment", then just look at the mobile modem (radio unit) and the mobile terminal (Computer).

I am as friendly as ever.

Yep, the man gets it. :twisted::twisted:
(Except it also includes a bunch of stuff about and connected to the network that has nothing to do with P25.)
