Went to Kingsport the other day, still was not able to connect to 4G around Jeff City, was able to connect around the Morristown and Greeneville exits. Also I was able to connect to 4G in Kingsport without having to toggle my phone.
Was able to map out Kingsport and Church Hill today. 4G speeds were pretty impressive.
Kingsport
Church Hill
I think Sprint is blocking the LTE signal around Morristown and the Jefferson City exit.
Wasn't able to connect to 4G around Jeff City, got a singal for about a second around Morristown, but I was able to map out White Pine, which was a surprise.
Kingsport seems to have better 3G speeds than Bristol or Johnson CIty. Rogersville also has pretty decent speeds. Morristown is kinda weird, near downtown the speeds are ok, off the interstate you may have better luck with smoke signals. Elizabethon doesn't seem to have had any work done yet. Nor Jonesborough.
GPS listing from LTE Discovery for a LTE signal
36.06200387, -83.39780471 - Near I-40 I-81 interchange
36.02434078, -83.47071834 - Near Asheville Highway on I-40(Jeff City) Showing in Sensorly
36.0085004, -83.5270977 - Near Exit 412 on I-40
I didn't realize that I-81 was showing 4G until I was in Greeneville, I took the back way home. I may head up that way tomorrow. I will try to do a speed test near 417.
Greeneville, TN
I mapped out some more area in Greeneville, it is showing in Sensorly now. Also near Jeff City, 4G is showing up, I don't know if I mapped that or not, since my phone was showing 3g but LTE Discovery was saying LTE.
The 3G along that route is a hit or miss. Near Greeneville it picks back up, Morristown is 2G, even in the city. Once you get close to Johnson City and Kingsport I have seen the speeds increase to over 1mbps.
I updated another forum, but I am seeing eHRPD all through out Knoxville, Pigeon Forge, Sevierville. WIl be heading down I75 today, will see what I can find down there.
eHRPD is showing up in Johnson City, Kingsport and Bristol, Tn. I was able to get over 1MB. Still waiting on Knoxville, although I was able to get over 2MB in one part of town.
