Instead of WiMax, give us EV-DV Rev. B or C

[FreakyLocz14]

That way, current EV-DO phones would be able to use voice and data at the same time, and newer phones can take advantage the Rev. B or C speeds.

I think what your talking about is
SVDO allow simultaneous 1x voice and EVDO data : EVDOinfo.com

personally, I'll take both please.

Yeah, that's what I was thinking of.

It is a lost cause, here is no room for voice only connections. Enacting that technology would actually set back bandwidth use, not set it forward. The world has a limited amount of bandwidth. During the first part of this century, we thought we could never use it all. In the last few years, we are learning we can. Today it is all about getting the most out of the bandwidth. Let me try to break it down. You typical phone call, depending on location, type of phone, and service, take about 8 to 17 kbps at 1.25mhz. Your typical video chat, once again, depending on place, phone, and service, can take up to 100kbps or a 3xmc connection at 5mhz. The future is about using the same bandwidth for faster speeds. A rough example. You get about 31kbps at 1.25mhz for you cdma voice on the phone.

If you convert that bandwidth over to lte or wimax and do voice over interent calling, you cant use less then 6kbps of connection and convert that 1.25mhz to about 2Mbps data speed. . So you can have 1.25mhz offering only voice at 31kbps, or you can have 1.25mhz offering voice and data at 2mbps with wimax and lte. Now lets say you are going to convert the 100kbps 3xmc at 5mhz.

Well with wimax and lte, you could get up to a 21Mbps connection for data, voice, and video chat, for 5mhz or you can have that same bandwidth offer only 100kbps at cdma. You can take the bandwidth of all voice/texting/video, which is about 10mhz, with cdma, that will get you about 150kbps of data line using cdma technology. OR. You can convert that to wimax and lte, use the 10mhz and offer up to a 50Mbps line. With Voip and Vcoip, you can use less then 30kbps. Leaving 49.7Mbps of data open for anything you want.

Why would you want to use more bandwidth and get less functionality and speed? Same bandwidth, 150Kbps vs 50Mbps. Dialup vs fiber optic speed, your choice.

EV-DO Rev. B gets up to 9.3 Mbps down, and Rev. C is almost as fast as T-Mobile's HSPA+ 21 Mbps down. It would be better because it would be easier to deploy network upgrades than building a whole new network. EV-DV stands for Evolution Voice and Data instead of Evolution Data Only, so voice+data connections are possible. Or SV-DO like IOWA said. And some of the current EV-DO Rev. 0 and Rev. A devices might see increases in speeds like T-Mobile HSDPA 7.2 phones are seeing from the HSPA+ network.

Ah but what would the cost of rollout be on each vs each? And WiMAX doesn't have a voice solution built in, yet.

Yea but b requires a 20mhz bandwidth, which could get you get you 50mbps.
Rev C uses 25mhz connection that could get you up to 70mbps. What is better, 9.3mbps vs 50mbps, 21mbps vs 70mbps? Second question. When a tower only has 20 to 40mhz. How do you add 10 people to that tower and divide 40mhz to 10 people and still give them 9.3mbps. That is hspa+ problem. Max speed of hspa+ requires one phone to have 1 tower. If you add 2 phones speed drops because you have to drop the mhz to match each phone. With 12 phones you get 1.25mhz per connection, which will get you about 2mbps. Once again, it is about using the bandwidth for maximal efficiency. Yes it does cost money to build out a network.

But using old technology that only digs the whole deeper will cost more in the long run.
Built in...qik.
But I never like built in so....
I am going to go with...
1. Truphone
2. Skype
3. Voxofon
4. Fring
5. Raketu
6. RF.com
7. PhoneGnome
8. Vonage Mobile
9. Jajah Mobile Web
10. Native SIP Clients
11. Google voice

Even still, it's going to be a while before voip in mobile handsets is reliable enough. I think sprint should focus on wimax 2

I use them every day, company requires sip address, not phone numbers. They are more then reliable 3g/4g areas. Wimax 2 is just upgraded handsets and more towers, both are coming.

So the future of telecommunications everyone would have their own SIP address, most likely customizable. Now there's an interesting yet conceivable concept.

Just like everyone has phone numbers today.

 

[eieio]

They need to do LTE and Wimax..

Finish the Wimax build out and add LTE 2 years from now..

 

[IOWA]

Just like everyone has phone numbers today.

But a custom SIP address (unicode i presume) would be more modern, and easier to remember than today's phone number system.

First EVDO Rev C is dead..

Second voice and data will come with newer chip sets.

Third I see Sprint doing EVDO Rev B MC maybe full Rev B but prob not..

China and Indina, and other huge providers in very big markets will do Rev B soon.. Also they will do 1x Advanced..

The biggest thing for Sprint is that China will be using Qchat, that will give them scale and cost savings when they re release Qchat..

[silencer271]

well give sprint the money its invested in wimax back and they will take advantage of your idea.

 

[rilharri]

lmao great post alot of information

 

[Seddy]

All of this sounds so nice... but lets not forget the few unfortunate ones (like myself) still waiting to be upgraded to EVDO.

 

[rilharri]

You will get it, like most of southern Indiana just got a few months back..

 

[Seddy]

I know we will get EVDO eventually but the question is.... WHEN? We were told they would make the switch mid-October and here it is a whole month later and we're still on 1xRTT. I dont know about anyone else but I'm tired of feeling like i'm on dialup whenever I want to browse the web away from my home.

 

[rilharri]

True, try Opera I use it when I'm roaming...

Also I bet its a backhaul issue, the telcos can take months to add additional lines ...
