    What is eHRPD?

    in Network, Network Vision/LTE Deployment

    Posted

    I just rooted my galaxy nexus and installed some ROM called EOS which came with CDMATools. I snooped in there and saw that eHRPD was off. Should I turn this on? My phone connects to lte just fine with it off but maybe there maybe some benefit I don't know about. Looking for anyone who has insight. Thanks.

     

    Yes, my friend with a Galaxy Nexus has a much easier time handing off between eHRPD to LTE than without. CM10.1 had eHRPD disabled by default for a long time up until recently.

    Almost cried when I saw that my phone has finally found the elusive LTE! This was just at the Whipple Rd exit in Union City.

    Awesome! I have some friends around there that would really like that. Does that tower cover Union Landing?

    I have some anecdotal evidence that the Optimus G is a slightly better CDMA performer than a S3, and significantly better than a GNex.

     

    Back to the ingress example, I've been playing a lot with friends, and whenever we go a specific spot in my neighborhood, my LG is able to hold onto a very weak EVDO signal and the game is playable. However my friends with the S3's and the especially the GNex, the game is simply unplayable.

    The Optimus G includes something called Qualcomm EcoMode. It actually increases battery life and helps deal with the temperature when playing games like Ingress.

     

    It's a great phone and this Jellybean update fixes the only issues I had with it. The primary reason I upgraded this phone is because of a spreadsheet that compares it's transmit power recorded by the FCC compared to other phones. The Galaxy Nexus was driving me crazy with its horrible CDMA performance.

    That is not a simple question to answer. For CDMA1X data, the most common (or, seemingly, the only permitted) radio configuration is RC3, which permits a max transfer rate of 153.6 kbps (oft quoted as 144 kbps). At the max rate, RC3 precludes use of one quarter of all codes in the Walsh tree. In plain English, it takes up one quarter of the capacity of the CDMA1X carrier. But RC3 does not operate at max rate unless capacity is available.

     

    That is the nutshell answer. Feel free to ask follow up questions.

    So does that mean for all of the data users on the carrier, 144kbps is available? Or could four users each get 144k?

    I am finally Level 4. I've been playing this game every evening for just under a week now. My neighborhood has about 11 portals within a square mile, however my Galaxy Nexus keeps dropping its 3G for several minutes at a time. Really sucks.

     

    Last night I got together with some random people in the Jack London district of Oakland California. Had a solid LTE signal the entire time. Playing this game with pre-NV 3G vs LTE is like night and day. Goes from being a pretty frustrating experience to a responsive fun game. I really can't wait for San Francisco to get LTE.

     

    One thing to remember though. Wear layers and gloves when you're playing this game at night in the winter. It got down to 27F before I called it quits and went home.

    So...which Sprint phone has the best RF quality?

    That would have drove me nuts. I'm glad I didn't have that same exact problem. However, the bug on the GNex of losing data connections all together was more annoying for me. Sometimes even a reboot wouldn't fix it!

    This is driving me crazy! I've been playing Ingress and it is horribly frustrating when the data drops out. Do you know of any fix or workaround?

    How much bandwidth does a single LTE site have?

    Watching this video, you would think the pico/macrocell concepts would have been implemented in wireless tech a long time ago, circa 3G. I can't believe they are just now getting this stuff in LTE R10. Planned obsolescence?

     

    They've had small cells for a while but managing the interference was always a problem. With LTE R10 they can partition the timeslots so that users on Picocells don't interfere with users on the Macro network, even if they are within range.

    Just recently found out you can search online for San Francisco building permits on this site:

    http://dbiweb.sfgov....ApplicantSearch

     

    If you type in Sprint as the applicant name and hit the "Building Permits" button, you can actually see many of the sites sprint will be upgrading and their current permitting status.

     

    Most of the permits I've seen are "Issued," however there are still a few that are being reviewed by the city.

     

    This is the sort of description of the work a typical permit will have:

    REMOVE 3 (E) SPRINT PANEL ANTENNAS. INSTALLED 3 NEW PANEL ANTENNAS INSIDE CHURCH STEEPLE. INSTALL 6 RRUS AT ANTENNAS. REPLACE 2 EQUIPMENT CABINETS WITH 2 NEW EQUIPMENT CABINETS INSIDE EQUIPMENT ROOM IN BASEMENT
