jefbal99 Posted May 3, 2017 Share Posted May 3, 2017 I've been very frustrated my network connections recently. I'm not sure if its my device or the network load balancing, but my Nexus 6P latches on to LTE B26 and just sits there. I can be in downtown Lansing, MI with visual site to 3xCA, 8T8R, Triband, full build sites and still be parked on B26. Due to the Canadian/US border, we are limited to a 3x3MHz FDD LTE carrier that is so over loaded, it is essentially useless outside of the middle of the night. I remember when LTE was first launched and only B25 existed there were limitations on network changes due to CDMA. My recollection from those threads and conversations was due to CDMA and LTE not being forward/backwards compatible, an active data session couldn't hand up from CDMA to LTE until a "quiet" period occurred. However, if LTE was lost or too weak, the session could hand down to CDMA via eHRPD. I thought it was explained that once LTE was across the board and all three LTE bands were available, the network and devices would be able to pass active data sessions up and down (i.e. B26->B25->B41 and reverse) because LTE allows and supports this type of load balancing. Also, its best practice to get a device on the most largest available bandwidth to get their data session completed. What I experience is that my device will go to B41 or B25 when it is idle, I start using it and I have a good network connection for a few minutes, but quickly I end up back on B26 and with a less than stellar thru put. I.e. 45 secs for a website to load, minutes for a snap to send, 10 minutes for an app to update, etc. I can disable mobile data on my device, wait about 30 seconds, then I'm back on B25 or B41, turn on mobile data and experience the same thing with getting shuffled onto B26. Is my understanding of LTE active data sessions being able to change bands incorrect or is something else occurring? One caveat for my experience at home is that I live on the border of two separate Sprint switches/regions. To the west I have a B25 & B41 site, to the east I have a triband site. However, when I'm in Lansing for work and other stuff, I'm one a single switch/network. Quote Link to comment Share on other sites More sharing options...
