There were many remarks on the fact that one could not phone and be on the internet at the same time with Neotel's product.

Is this due to below par hardware, or is it a limitation of the CDMA technology used?
 
Why not pipe the voice over the data connection aka voip !?
 
Most probably a limitation of CDMA, or maerketing tactic.
I think its to ensure Voice Qualit/Clarity
 
It's so stupid you can't phone while on the net. It's the only think that will stop me from getting a Neotel product. They need to address that.

I'd also be intereseted.

Doesn't GPRS/EDGE (2.5G/2.75G) suffer the same restriction, while UMTS (3G) does not? Maybe V3G can verify?

Is CDMA2000 is more like 2.99G than 3G?
 
for me this is simple , il keep my telkom line and use neotel just for the internet

I never knew that. ByeBye Neotel
 
I find it a little disturbing that you can't phone while on the Internet. From a marketing perspective this could be something that bytes Neotel in the behind..

Anywayz... I won't get it because of this... damn.. and I was looking forward to dumping Telscum. Makes it a little useless for small business purposes...

its just there launch , they said they going to offer fibre based so i cant wait for that but theres 1 prob if they offer fibre and im tied to their contract thats gona suck but the again i can just pay off the contract n take that
 
I blame cr@ppy implementation. Just check how little bandwidth skype uses....triple that and then you've got solid voice quality. Now with their so called broadband connection there should still be buckets of bandwidth left to surf a bit.:confused:
 
IIRC NeeTel announced [rather proudly] at last year's MyBroadband Conference, that NeeTel had designed its own handset, somehow I suspect that the design did not account for users wanting to use voice and data at the same time :rolleyes:.

Someone posted somewhere that it is theoretically possible to have more than one NeeTel handset associated with the same NeeTel number - much like one or more Telkodemonopolies phones plugged into RJ11 extension sockets, so theoretically one should be able to have 2 handsets in one's home, where one is used for voice and the other is used as a modem for data.
 
CDMA2000 1xEV-DO achieves higher data and spectral efficiency than HSDPA partly because it separates the high-speed data (EV-DO) and voice / low-speed data (1X) carriers (which carry very different profiles of traffic). Whilst this gives the technology a clear performance advantage (more users on the system at higher rates, better use of available spectrum), it does mean that any particular device can only look at one of the two carriers at a time (either voice or high-speed data, but not both). There's typically no limitation on the network, but, in order to do voice and data simultaneously, an EV-DO device would basically need two radio transceivers, and two chipsets, much like a dual-mode phone. EV-DO Rev A provides the speed, latency and QoS to support carrier-grade VoIP on the data carrier (and is the only wireless technology that can do this efficiently), but this is only supported in recent chipsets, and not really in commercial use yet.
 
I can see that this could be a big problem, Luckily for me I don't phone that much. I actually got a fright every time my telephone rang at home as nobody was suppose to have that number.
 
They should simply offer a data-only product(with a proper wireless /wired router option) at a reduced rate. Most of us have phones anyway.
 
its their 1st product and i have to say its good for their first , il definitely take it while i wait for their fibre offerings to come out

Unless you represent a large corporate, you're going to wait a long time for FTTC|FTTH.

2G, 2.5G, 2.75G, 2.99G, 3G, 3.5G and now 4G.....all marketing terms....they seem to mean whatever the latest hype is....:rolleyes:

CDMA2000 is part of the 3GPP2 set of standards but is not compatible with the WCDMA (UMTS) version of 3G, which is part of 3GPP and used in most of the civilised world (i.e. outside the US! :)) Even in the US UMTS is fast becoming available, so there is uncertainty about the future of CDMA2000.

On WCDMA it is possible to do voice and data at the same time but is a function of the type of device you have (the so-called 'class').

So in the case of the Neotel service it could just be a limitation of the device but it could also be a limit in the standard. Not sure.

The the 2.99G was used in jest.

The main question I was asking is whether no simultaneous voice & data was also inherent in the design of GPRS/EDGE, both at a CPE and network level?
