WiFi Calling.

Recommended Posts

No carrier on the planet has perfect indoor coverage.

 

Sprint should license the technology from its MVNO Republic Wireless and have it built into all of its future Android handsets.

 

Its absolutely awesome, it completely eliminates the need for an AirRave and more importantly, its like taking your own AirRave with you to OTHER places that have poor indoor coverage. Brownstone apartment buildings, homes near unfortunate geographic features, sports stadiums, industrial or office settings, lower levels of a shopping mall. etc.

 

There are tons of places that have poor indoor signal penetration and an available wifi network, it really is that good of a feature, you quickly start to view it as indispensable once you get used to having it on your phone.

Sprint, as a national carrier, will take years to vet any technology that allows you to make calls outside of their network. They don't like losing control in any way and wifi calling takes the control out of their hands when making calls. One reason is actually quality. They don't want to have to diagnose a dropped phone call because you were torrenting Game of Thrones. It's an unknown and national carriers are very hesitant to jump in and support it. T-Mobile is the first because they have the least coverage and customers and will do a lot more to make their customers happy than other carriers.

 

WIFI calling is actually a pretty standardized technology. It's just that the carriers still have enough spectrum that they see it as a last resort.

Sprint isn't going to allow garbage wifi connections ruin the sparkling reputation their voice service has earned. I've made calls over my wifi, which is really fast and low latency, and they were garbage. If people want to call on wifi, there are apps to allow it, no reason for sprint to put their name on substandard voip.

 

Here is a speed test of my wifi for reference:

The idea of a decent reliable official wifi calling tech that allows you to use your number and is totally integrated, as T-Mobile has had and other companies like Republic Wireless offer would be an awesome advantage. Full bars wherever you can get WiFi would be awesome!!!

I think if they had a GAN/UMA based system like T-Mobile and some other providers, it would be great and alleviate a lot of those concerns. GAN/UMA essentially makes your phone it's own femtocell (like its own Airave) over wifi, Sprint's network would just see you as connected to another base station

I fail to see how carrier implemented WiFi calling takes control out of their hands anymore than using an AirRave would, which in itself is a clunky, round about way of routing calls over a third party internet connection. An AirRave isn't immune to those same kind of external network performance issues. When talking about control, ultimately it would be Sprint's implementation, using Sprint approved encryption schemes and ultimately connecting to Sprint approved VOIP servers.

 

T-mobile has had it for years through various implementations of the UMA standard, but quality issues are minimal on the Sprint side. I've had a Republic Wireless phone that I've been using as a second line for almost a year and its been outstanding, the feature set is absolutely mature enough to be implemented on the post-paid side.

Airrave has to authorize and meet Sprint standards.. It might even have to pass speed/latency tests and have a ec/lo ratio. Also, when you leave wifi and go into the carrier network is it a seamless voice transition?

 

RW/T-mobile UMA won't enable (you'll get a red icon) if you're on a bad WIFI connection that doesn't meet minimum performance standards, there's some sort of connection testing going on when the feature is initiated.

 

A warning pops up that the user is about to leave the WiFI coverage zone and the call ends.

 

Seamless hand-off is pretty much an impossibility as I understand it, but regardless the feature is so useful, you're more or less talking about the complete elimination of all indoor coverage gaps.

T-Mobile wifi's application is pretty bad, unstable and is very visibly intrusive when running.

 

Plus....... when enabled, the phone still is looking for a signal, so the phone battery dies just as fast, if not faster when in an area of no signal. If its in an area of marginal ATT signal, the battery dies even faster, as its roaming and is searching for a home signal.

 

Airave is much better than their wifi calling.

 

If you want to use your phone on wifi, use the free apps that are free to use such as Vonage or T-Mobiles Bobsled.

I have a pbxes.org account set up with my Sprint-integrated Google voice account. Using CSipSimple or the built in SIP client on some ROMs, I can do WiFi calls using my Sprint number. I've found that using SIP provides a much better experience than using something like GrooveIP. Latency is better, and the connection is much more robust. It can even do hard-handoffs between WiFi APs and cellular data. Audio is lost for the time without data, but the call doesn't immediately drop. In my experience, the interruption is typically less than half a second.

    • In the conference call they had two question on additional spectrum. One was the 800 spectrum. They are not certain what will happen, thus have not really put it into their plans either way (sale or no sale). The do have a reserve level. It is seen as great for new technologies which I presume is IOT or 5g slices.  They did not bite on use of their c-band or DOD.  mmWave rapidly approaching deadlines not mentioned at all. FWA brushes on this as it deals with underutilized spectrum on a sector by sector basis.  They are willing to take more money to allow FWA to be mobile (think RV or camping). Unsure if this represents a higher priority, for example, RVs in Walmart parking lots where mobile needs all the capacity. In terms of FWA capacity, their offload strategy is fiber through joint ventures where T-Mobile does the marketing, sales, and customer support while the fiber company does the network planning and installation.  50%-50% financial split not being consolidated into their books. I think discussion of other spectrum would have diluted the fiber joint venture discussion. They do have a fund which one use is to purchase new spectrum. Sale of the 800Mhz would go into this. It should be noted that they continue to buy 2.5Ghz spectrum from schools etc to replace leases. They will have a conference this fall  to update their overall strategies. Other notes from the call are 75% of the phones on the network are 5g. About 85% of their sites have n41, n25, and n71. 93% of traffic is on midband.  SA is also adding to their performance advantage, which they figure is still ahead of other carriers by two years. It took two weeks to put the auction 108 spectrum to use at their existing sites. Mention was also made that their site spacing was designed for midrange thus no gaps in n41 coverage, while competitors was designed for lowband thus toggles back and forth for n77.  
    • The manual network selection sounds like it isn't always scanning NR, hence Dish not showing up. Your easiest way to force Dish is going to be forcing the phone into NR-only mode (*#*#4636#*#* menu?), since rainbow sims don't support SA on T-Mobile.
    • "The company’s unique multi-layer approach to 5G, with dedicated standalone 5G deployed nationwide across 600MHz, 1.9GHz, and 2.5GHz delivers customers a consistently strong experience, with 85% of 5G traffic on sites with all three spectrum bands deployed." Meanwhile they are very close to a construction deadline in June for 850Mhz of mmWave in most of Ohio iirc. No reported sightings.
    • T-Mobile Delivers Industry-Leading Customer, Service Revenue and Profitability Growth in Q1 2024, and Raises 2024 Guidance https://www.t-mobile.com/news/business/t-mobile-q1-2024-earnings — — — — — I find it funny that when they talk about their spectrum layers they're saying n71, n25, and n41. They're completely avoiding talking about mmWave.
    • Was true in my market. Likely means a higher percentage of 5g phones in your market.
