Good speeds.

Pings are kinda high.

Will devices maintain the same IP address handing off from 3g to LTE and vice versa? One of the problems with the WiMAX implementation is different networks / different IP addresses creates a not-so-seamless experience. The goofs up streaming music/video applications for example.

Nice. I get similar numbers in Minneapolis Minnesota area.

Reminds me of the loss of connection issue with the Galaxy S II that was patched 3 months later.

Typical New York. Taxing everything any anything

Anyone know how the overall deployment of NV is going on in the District? My speeds keep fluctuating from 1.5mbps to 88kbps. I posted on Sprint's forums thinking it is just an issue in the area but they don't have any notes of Tower issues. Frankly, I was hoping that the high speeds were Sprint testing the new towers but it has become rather inconsistent.

 

It could also be the plethora of new tourists that infiltrate the area around my office (we work across from the White House).

Perhaps the phone is bouncing between newly upgraded towers and the older towers?

I suspect embedded SIM or virtual SIM would be to still allow for billing "by-device" as they have different rate plans for SERO, regular plans, and feature phones.

Found some info.

 

"High block/drop rates: During the migration to Network Vision those customers on the boundary between NV sites and legacy sites will experience a higher than normal block/drop rate. The rate will continue until the boundaries are reduced by the introduction of additional NV sites."

i wonder why.

If anyone knows anything about voice latency, with regards to HD Voice, I'm quite curious.

cool cool. i'm shocked and excited about doing hd voice already. i had assumed that was 2-3 years out still.

I rooted my phone with HTC's tool and it did a factory reset. My speeds are back down to 10-30kbps even after doing a profile and PRL update. I was getting 200kbps+ before the factory reset. What gives?

Probably tower saturation or something like that on the tower end. There's no "magic" to radio versions that people seem to think there is.

keep em coming

Using the Sprint issued prl this morning I pulled the fastest 3g download speed I have ever measured. From a tower a couple miles from the tower shown on the map I got 2.2 mbps download, 700k upload. The speeds were consistently over 1.5 meg. I suspect my issue was speedtest.

awesome.

iPhone/iPad user here, and I firmly believe Android is prettier and easier to use than iOS, and Google Maps Navigation is amazing on Android.

what's drive testing? driving around, testing?

My ping to the SIP/RTP server had been under 40ms (one way would be 1/2 that, or 20ms then) and when I used a VoIP adapter I set the buffer to 10ms the minimum. Yet VoIP voice lag was still about 300ms (one way) or about double that of a cell phone. That means VoIP was adding about 270ms somehow, after traversing the internet to the VoIP terminal. Yuck. I never measured with airrave/tmobile but subjectively it felt about the same using the "click test", just call yourself on a landline (so hold one phone up to each ear), and "click"/pop your mouth in one end, and you can get a good feel the lag. If you use google voice try adding that into the mix too for fun, GV adds another 130ms lag on top

I'm not sure it has to be that way. I use Broadvoice VOIP at home and often run 200ms pings and it works great. You would think that if someone had WiFi in the 200ms ping range or better, they would be able to devise something that worked well with that.

That's interesting and I was thinking about that. Maybe in New Mexico you are a lot closer to the POTS termination. That POTS termination is like long distance lag in addition to the internet lag. I think in Minnesota I've got the latency to the data center, plus the POTS network latency on top of that...gets pretty high, I suspect data centers are on west/east coast. Maybe near the coasts it's better. Just a hunch. But I've tried many VoIP sprint, tmobile, a few other voip providers and Airrave in MN on a fast low lag conneciton and its been noticably bad for voice calls -- not just me but the people on the other end basically say "i can't talk to you over this connection"!

Cellular phone calling is about 150 ms lag, which is pretty bad already (2 cell phones then is 300 ms)

Wifi calling tends to be double that, and makes for a bad to terrible experience...1/2 second and longer delays piss people off. Also wifi calling often has volume issues, and the higher latency results in echo and bigger echo cancellation problems.

Cool - this is pretty neat

I wondered why when they deployed WiMAX, they didn't tell the phone via 3G to tell the phone where 4G was available, rather than scanning

It's not anything I worry about. Based on Sprint's keeping unlimited ads going strong and Hesse's continual comments on it, there is no reason to be concerned that LTE will be a catalyst to ditch unlimited. It would not be until LTE is starting receive significant usage burden that Sprint cannot mitigate with easy solutions like 800/2500 capacity enhancements that I think they will scrap unlimited.

 

I'm a believer that Sprint is banking on an unlimited LTE iPhone to save the day!

100% agree. Also with LTE being 2x or more spectrally efficient than 3G, if they can offer unlimited 3G they should be able to offer unlimited LTE.

Random reboots is a hallmark of many Android devices unfortunately.

This is merely a statement of fact, please don't turn this into another tiresome android/iOS argument.

OP let me put it to you this way....LTE at 2500 Mhz will reach farther than Wimax at 2500 Mhz alone. Wimax at 2500 Mhz has a threshold of around -85 dBm before it drops off hard while LTE at 2500 Mhz has a threshold of around -105 dBm which means LTE will have better in building penetration than Wimax. That alone tells you that LTE and Wimax at the same frequency is already better with LTE.

Is this because of how WiMAX devices are provisioned to disconnect at -89 dBm or worse signal? Or something inherent to WiMAX?

Every month after the 2 year period, you're basically throwing away an extra ~$14 ^[*] per month to Sprint if you don't upgrade. So, no, you don't have to upgrade, but it's in your best interest financially to do so.

 

^{[*] Assuming that Sprint prices plans to ensure break-even for the subsidized phones that cost Sprint the most. e.g., a $550 phone sold for $200 means $350 is made up over the course of 24 months at $14.58/month.}

By that logic, shouldn't everybody buy the iPhone since it's subsidized the heaviest?

And isn't having what you want is worth waiting a few months for, even if it costs you $14.58 a month?

There are some areas in the country where Sprint is downright poor. I think that they will have some problems keeping subscribers in those places.

 

However, performance at Network Vision sites is sounding very good. I just got two reports from S4GRU readers that a site in New Bedford Mass that used to be poor is now humming above 1.6Mbps since NV completed on it a few weeks ago and sub 100ms pings.

 

I do think Q1 subscriber numbers could be an issue, as not many people want WiMax units at this point and we are in the middle of device famine. But this ends on 4/15. 2Q will probably shift that.

 

Robert, Roberto, Admin, Hey You! Its all good! But this was posted from my E4GT with ICS using Forum Runner

whoop whoop! this is great news!!
