Connection problems

According to HTC, the Evo V 4G is not directly compatible with 1x Advanced. The Evo V 4G is only compatible with CDMA2000 1xRTT, EVDO rev. 0, EVDO rev. A and 4G WIMAX. [HTC Specs]

1x Advanced is backwards compatible with regular 1xRTT devices, and better for all users when you look at the network as a whole, but to take full advantage of the 1x Advanced base station upgrade the handset must also be specifically compatible with 1x-Advanced.

You may be right.

But the radio transceiver already supports the required band, and 1x Advanced is not in service yet. I expect that at most an OTA upgrade would be required, provided that the carrier agreement allows it (and I suspect that it does).

1x Advanced is going to be on the same band that Nextel iDEN was, this phone is capable for the band.

Fwiw, I respect HTC (look at my device list and add Evo 4G), but their website has been known to be less than accurate.

...whereas the EV4G is a quad band phone, supporting 800, 850, 1900 and 2500 mHz frequencies. Our phones will be able to benefit from Network Vision, if it'll be as good as they're letting us believe anyway.

I know I'm splitting hairs here, but the Evo is a dual band phone. The CDMA radio operates on the 800 and 1900 MHz bands. The 2.5-2.7 GHz capability is for WiMax (or 4G as Sprint calls it,) which is data only (you can't make calls on WiMax.) There is no 850 MHz on Sprint, but GSM carriers use it.

The Evo V 4G has a tri-band CDMA radio that can access the 800 MHz SMR, 850 MHz Cellular and 1900 MHz PCS bands. (VM customers aren't allowed to access the 800 MHz "Nextel" CDMA network or the 850 MHz Verizon/smaller regional carriers CDMA networks, but the phone is technically capable.)

The phone can also access Clearwire's 2500 MHz 802.16e WiMax band. Handset marketing baloney usually only counts licensed frequency bands (so not WiFi, not Bluetooth) and in that case the Evo V 4G is correctly described as a quad band phone.

1x Advanced isn't frequency band specific. In the Sprint network, 1x Advanced is going to be on both bands - 800 MHz and 1900 MHz.

When it comes to end devices, an OTA update won't cut it, not just for the EV4G, but for every device. The device has to be specifically engineered in hardware from the outset in order to be fully compatible with 1x Advanced.

Right now there is only one phone on sale that meets the 1x Advanced requirements - the Huawei 886 Mercury from Cricket (which makes sense since Cricket has the only operational 1x Advanced network in the U.S. (and maybe the world still)).

Most aspects of 1x Advanced are good for everyone, even those with "old" phones get 75% of the benefit no matter what. The HTC Evo V 4G and every other phone currently on sale in the U.S. except the Huawei Mercury fits into this "old phone" category.

According to Sprint statements at s4gru.com, 1x Advanced will only be on the lower band, not 1900 MHz. Please show a link to correct me if I'm wrong, thanks.


And the HTC EVO 4G LTE is spec'd as ready for 1x Advanced, and has the vocoder in place to perform HD Voice, using the 1x Advanced services to do so.

And unless the radio transceiver in the phone can hit the band, no 1x Advanced on Sprint towers, that's not 99% of the phones, but does include the Evo V 4G.

If it's true that you can't access the lower bands on VM, then I think that getting 1x Advanced advantages will be a problem.

PS - quad-band is a term usually reserved for the GSM community, even if four bands are capable here.

Please link to the s4gru article you are referencing above. (You do see the irony in how you handled that, right?) s4gru is just another forum - the info could be spot on and refer us to a high-quality, verifiable news story or Sprint press release or it could just be typical, unsubstantiated forum drivel. You could be dead on right, but how would I or anyone know? I'd be happy to discuss this further, but I can't really respond if I don't know what you are referencing. Help me out here.

Give me a break. That term is not reserved for "the GSM community" by any standards body, professional organization or group of any consequence. It's probably true in your head because you're used to the way things used to be. Things have changed. The way we describe subscriber equipment needs to change to match the way things actually are, not the way they once were. The Evo V 4G can access four FCC-licensed spectrum bands, making it a quad-band phone - the fact that GSM phones have also been described that way in the past doesn't amount to a hill of beans.

There are definitely issues with this phone. Tonight someone tried to call me for 60 minutes, left TEN voice mails. I was in my NYC apt all the time. Phone did not ring once. Phone did not show any missed call either. Only when I turn on the mobile did the voice mail app show there are voice mail pending.

When I logged into my Virgin Mobile account and traced the call history, I noticed the missed calls have 62450000000012 as the caller id, not the actual person's calling number. It is one thing to miss text, but it's another when there are emergency calls. I am getting frustrated here.

Another observation I noticed is that when I was using OV, the calls would registered quickly in web account call history. With Evo, calls don't register right away.

I really hope VM fix this quick.

Gladly, I didn't intend to be evasive.

I'm literally doing a number of things at once, so I will come back with that.

If you're not familiar with s4gru.com then I think that you'll enjoy it. Sprint guys run it.

And because I do a lot at once, I have been known to be wrong, I have no ego about it. So, I thought if you had a link handy and I didn't... you know.

Wow. Slow your roll, there compadre.

Around here, we attack issues, not each other.

Making remarks about what's in my head in such a negative fashion is not the way.

You want to know where I am coming from, ask, buddy to buddy. Never a need to be harsh. Never. Please consider this as formal guidance for AndroidForums.com. Ok? Ok, thanks,cheers. (if you're on Tapatalk or something, you probably can't see that I'm a mod here)

To answer the question, I simply meant in the common, de facto vernacular, "quad-band" is used by most quasi-news blogs and phone spec sites when referring to GSM phones. Regardless of spec or standards bodies, it may confuse people to use the term here.

As I don't like people being confused on our forums, I decided to toss that out to soothe a possible point of contention.

It was already turning into a pointless argument without a reason, really.

It's probably not helpful, but I have seen this complaint levied against a number of phones today, not just this model.

I hope that this gets fixed soon as well.

Do you know what other phones are having trouble as well? Is it on Sprint only?

I was thinking that it can't be this phone. My speculation is that VM has provisioned EVO to use Sprint's system, server. When a call is made it routes the call to Sprint system instead of VM. I suspect somewhere along the routing, Sprint need to verify VM accounts, and that verification can't be made. Hence, the calls are not being sent.

I've just sent VM an on line message. I really hope they solve this soon.

Sprint EVO 4G LTE, Samsung SGS2 Epic Touch and two others I believe - on Sprint.

I haven't been around to all of our corners here on this, we have a lot of forums.

Thanks for the info.
Hmmm, so looks like a sprint issue. I will try to do a search. I hope this has something to do with their new network implementation. If that's the case, I can live with the short term annoyance.

Thanks, that's fine, I understand. Maybe we should take this to a new thread or to a Network Vision thread? We getting a bit off topic. Just a thought.

Take it easy, now. It's possible that you are over reacting just a bit. I apologize. I honestly do not agree that the simple phrase "It's probably true in your head..." amounted to an attack on you. (If it had been my intention to attack you, then that has got to be the mildest, most innocuous attack ever in Internet forum history.) If you feel the need to discuss this further, I'm happy to hear what you have to say, be mellow and work it out, but it needs to move to PM.

It's my opinion that telling people the truth isn't true doesn't reduce confusion, it creates it. Even if what you said was demonstrably true at some point in the past, it's obviously not true anymore. Quad band CDMA phone exists now. That's a fact. People will be much less confused when you describe things as they actually are.

(Also, why would you let "the GSM community" tell you what you can and can not say? I for one and not going to let "the GSM community" tell me what to do! You've got to be tired of having them dictate to you. Stand up for yourself and revolt!)

 

[EarlyMon]

+1 on all the above.

But let's re-engage after the 4th. Busy time.

Apologies if I read you wrong, guess I did.

 

[shadal]

Well....

I received my Virgin branded HTC EVO V 4G and immediately after activation everything worked.

So, is there a difference between Sprint branded and Virgin branded VM phones? I don't know (most likely), all I know is the VM one worked immediately whereas the two Sprint ones failed.

Only thing I don't like about this one, is the power button is too recessed. Both sprint phones had nice touchy, clicky, power buttons...

That can be fixed by putting a tiny piece of electrical tape on the switch itself inside the case. I had to do that for my Sprint branded phone. This problem appears to occur in both "types" of phones.

Thanks, I did see that video. I just haven't found my electrical tape yet
