How are the handoffs (between frequencies) supposed to work?

Hey guys,

 

Long time lurker, first time poster.

 

I have a question about how the phones will handle the handoffs between the 800, 1900, and 2500 bands. Currently, the switch to 4G to 3G or 3G to 4G is anything but seamless. Websites and media stop loading during the handoffs. When NV is fully implemented, do we expect the phones to have stability between the frequencies?

good question. I think between 800 and 1900 it should be. not sure about 2500 as it will probably generate different ip unless if it is 2500 hosted by sprint itself.I know there are chips which do seamless switch between FD and TD but in our scope TD is hosted by different company(subsidiary of sprint)

eHRPD exists for CDMA to LTE hand-off, WiMax to EvDO is impossible because no hand-off technologies exist. 3G to WiMax and WiMax to 3G hand-off probably doesn't have a hand-off method/technology to my knowledge. 3G is ran by Sprint and WiMax is ran by Clearwire, there's latency and involved that could possibly cause problems. LTE should be able to handle hand-off from carrier to carrier without issue regardless of frequency.

I've heard it both ways. A few on this forum have said it can't be done because of the different gateways/networks/etc.

 

However, the guys over at clearwire have said that it will be a "seemless" handoff (they've even said they will support VoLTE).

 

Personally, I am very interested how this is going to roll out.

if it is seamless

I dont know if TD works good while on the move..if it does not then there should be option to toggle switch on and off 2500.

TDD works fine while moving. In the Sprint/Clearwire program documents for system planning between their FD-LTE and Clearwire's TD-LTE, the systems are being coordinated to handoff to each other while in motion. How successful it will work remains to be seen, but they are planning for it.

While handoffs work much better when both share the same network, it can be made to work between completely different networks. The device must be registered on both networks. In this case, most of the device handoff logic resides on the device itself. CDMA 1x and EVDO have the capability, but the CDMA vendors have chosen not to implement it.

      Kind of amazing that T-Mobile is still holding onto that speed title despite Verizon all but killing off lowband 5G on their network. While Verizon is mostly being evaluated on mmWave and C-band performance, T-Mobile and AT&T's average 5G speeds include their massive lowband 5G networks that are significantly slower.

      Yup. Very true. We were originally on an Everything Data 1500 Plan, which got Unlimited Minutes thanks to Marcelo's "Loyalty Benefits" offer. We then switched to Unlimited Freedom (with the Free HD add-on that Sprint originally wanted $20/month per line for.... remember that?) because the pricing was better with "iPhone for Life", vs. the "Loyalty Credit" for staying on a Legacy Plan. After that, I ran the numbers and switched us over to Sprint MAX, especially for the international travel benefits. There's absolutely no reason for us to switch to Go5G Plus or Go5G Next if we're going to do BYOD by purchasing from Apple/Samsung/Google directly as we've been doing. These new plans aren't priced for current customers to switch to. They're price for new customers, where they throw in a free line, etc. It's gone from "Uncarrier" to "Carrier". What a shame.

      Strange business model that they keep around all these pricing plans. 1000s of plans per carrier is reportedly not uncommon.  Training customer support must be a nightmare. Even MVNOs have legacy plans. A downside of their contract mentality I guess. Best to change contracts during a recession. But then all carriers try to squeeze out legacy plan benefits as they grow old.

      Everything "Uncarrier" is becoming "Carrier" again. Because of the Credit Limit that T-Mobile put on our account for no reason at all (and wouldn't change/update the last time I checked all the way up to the CEO), I don't plan on buying/upgrading our iPhones through T-Mobile. I'm going through Apple directly. Looks like I'll be going through Google and Samsung directly for our other lines for upgrades. Also, we're staying on Sprint Max given the ridiculous pricing for Go5G Plus. On Sprint Max, we currently pay for our Plan: $260 for 7 Voice Lines $25 for two Wearable Lines. (One is $10/Month. The other is $15/Month because the AutoPay discount only applies up to 8 lines.) Total: $285/Month vs. Go5G Plus (Per the Broadband Facts "nutrition label" on the T-Mobile Website): https://www.t-mobile.com/commerce/cell-phone-plans $360 - ($5 AutoPay Discount x 7 Voice Lines) = $325 The Watch Plans show as either $12/Month or $15/Month: https://www.t-mobile.com/cell-phone-plans/affordable-data-plans/smartwatches So this is about the same for the wearables as what we're paying now. Overall, it's quite more than we're paying now to switch plans. Ridiculous....
