Wifi-3g handoff


Recommended Posts

Hi everyone, first time poster. Here is an article I found about seamless wifi-3g handoff.

 

http://www.qualcomm.com/media/documents/files/3g-wifi-seamless-offload.pdf

 

The case in which this is useful is, turn on ESPN radio or NPR streaming, then go walk the dog. When I get out of range of home Wifi, stream breaks and I have to go into the app and restart it.

 

I understand NV will bring LTE-to-3g seamless hand off (huge improvement over current situation with Wimax). What about Wifi?

They need to figure out how to get the new EVO to pick up a 3g connection after leaving a WiFi area first. Right now you have to reboot the phone if you forget to turn off WiFi before you leave the area.

I leave my wifi on almost every time i leave the house and have never had an issue getting 3G. It as never been an issue on either my original EVO and the EVO LTE.

Happens just about everyday for me. Data falls on its face about twice a day now it seems requiring a reboot. The phone was great for the first few days but now it has gone to pot.

 

I think mine has an issue of leaving WiFi and the airave at the same time.

 

Going to call sprint tomorrow and have them send me a new airave with the 3g on it otherwise this phone is going back to the store.

Maybe because your wifi covers half the neighborhood? LOL

I think I saw a pic of digiblur's Wi-Fi antenna in another thread. Yeah, here it is...

Let's just say there's going to be technical issues getting an IP stream to hand-off between a wifi network and a wireless carrier. The best solution would be for the application to prebuffer the stream and reconnect before the buffer is empty.. Or just turn off your wifi before you start the stream.

Thanks, did you read the article in the first post? It details a technical solution to the problem. I am asking if Sprint is implementing that or a similar solution.

The Qualcomm document indicates that some form of this is part of 3GPP Release 8. Where does Network Vision fit in with 3GPP, 3GPP2 etc. ?

I do run another wireless stream from another router for guests that's on a different VLAN than everything else in the house. It's your typical residential wireless range from 802.11n. I'll have to try hooking up to it and see what happens. As it happened again this morning when I left the house.

I don't recall ever seeing any specific "3GPP" Release numbers in any Network Vision docs I have seen.

Yes, I read the document, they are planning on overcoming the technical issues by routing all of your traffic through a box/boxes owned by the wireless carrier that would act as a proxy for your device. This makes me nervous. I'm not sure anyone will implement this due to cost, not to mention how upset would you be if that box stopped working and you could no longer use wifi or 3G/4G to connect. Its a lot of overhead for a very small benefit. IPv6 already has mechanisms for this type of hand-off built in and I see that getting implemented before this.

    • Another SCP beta is rolling out now, with some bugfixes as usual but also some fun new options to test: Non-standalone 5G-NR cells can now display Site Notes. This feature works in the same manner as how neighbor cell notes are displayed, requiring a PCI and your device's location. This option is enabled by default. As is the case with neighbor cell notes, you cannot edit NSA site notes directly unless there is an NCI being reported (which I have never seen); it uses the previously recorded standalone log entries. Like neighbor notes, if a cell has been previously logged but there is no note, you will see the distance information only.   Logging cells that are not reporting a valid PLMN is now possible. This option is disabled by default, but if you enable it along with two other options (log sites with missing GCI/NCI and to log sites with missing TAC), you should begin logging most NSA 5G-NR cells. A PCI is needed at a minimum, which is not always reported depending on your device and network factors. ("Sites" will be renamed to "cells" on the Preferences menu in the next update.)   Users can enable an option to display LTE cells above 5G-NR cells in the app if they choose to do so. This option is disabled by default. Should help improve the readability of your screen if you have NSA 5G-NR cells constantly appearing/disappearing. Please give these options a try and let me know if you notice any issues.. thanks!
    • Not yet. We probably won't see one submitted until construction on the new building is substantially complete. 
    • Yes, that is where the site used to be. All the antennas were removed. I hope they add a new site soon. Have any permits been submitted for a new site?
    • Looks like there's a slightly taller building going up next door to where the decommissioned site used to be. Taking a look at StreetView, T-Mobile likely decommissioned the site because the east facing sector would blocked by the new building. If I had to guess, T-Mobile has already agreed to move to the roof of the new building and is just waiting for it to be completed to install the site there. What they should've done is just rearrange the sectors in the meantime but it seems like T-Mobile just bit the bullet and decommed the tower in the short term. — — — — — A permit was issued for a Sprint conversion at 150 Prospect Park West, finally filling in what is T-Mobile's largest coverage gap in Park Slope. Verizon is collocated on that building and AT&T has placed small cells along Prospect Park West to fill in coverage there while T-Mobile struggled using two sites, one at Grand Army Plaza at the far north and another at Bartel Pritchard Square to the far south.  
    • Yep, you can see the site was taken down between Aug 2022 and Apr 2023.
