It's probably a few pages back, but that site's data connection was disrupted during one of the storms a ways back. I think that's probably the only reason it's still offline. 

Ok so back now and still connected at home. Driving back from the west side of the city I'm not so sure there are any active towers over there.

With -102dB here, I bet it would reach over to Washtenaw if you didn't have trees in the way looking towards Main. I hope they can get a tower on South U. completed soon, that would be a pretty big and contiguous coverage area.

It was on continuously from when I first noticed it until I left Ann Arbor at 15:00, I'll find out when I get back later?

LTE literally just went live in downtown Ann Arbor! I've had my iPhone plugged in with Signal open 24x7 lol.

Hill and State, I'm connected to physical cell ID '75', which I've never seen before. -102dB from inside my apartment.

15.57 Mbps down, 4.2 Mbps up, 67ms ping. Awesome.

I think that dot on South U. has been there for a while. If you go on any building downtown to at least the third floor and face south you can pickup one of the existing towers.

Went back to work on my project and got the two bars of LTE on the rooftop again. Not really sure where the signal could be coming from since it's quite a ways away from the Plymouth and Ypsi sites

Can you get the signal strength in dB, it might give us a little better clue which tower it's coming from..

1) From the Phone app, dial *3001#12345#* and hit Talk

2) Once field test opens up, it'll show you the numeric signal strength instead of the bars

Then, if you want to keep it showing signal strength (until the next reboot)

3) Hold down the power button until it gives you the slide to power off screen

4) Instead of sliding to power off, just hold down the Home button until it takes you back to your home screen, then it'll keep the numeric signal strength up until next reboot

From the top of the parking garage on Thompson I was pulling 5.25Mbps down and 1.8Mbps up with a signal strength of -114dB (and that was connecting to either the tower across 94 from Briarwood or the one south of 94 on Platt).

A couple observations from Ann Arbor today that may or may not mean a thing.

- My iPhone's signal indicator keeps showing 0 bars ( -106 dB) and switching between 1x ( o ) and 3G on an off again throughout the city

- Several times I've received a message about failing to connect to the data network

- Just last night I noticed on Sensorly's maps a new patch of LTE was picked up at 23 and M14 (the northeast corner)

Keeping my fingers crossed

Perhaps on a boomer site with little downtilt. An urban/suburban site would be too low to the ground with its panels pointed toward the ground...so additional range would not be possible in those instances.

Ahh, thank you for the clarification

Got and mapped out 4g last night in Canton again. For the most part it was steady and picked up on it's own. However, it would occastionaly drop for no apparent reason neededing a airplane mode toggle or a few. I can't seam to find an active tower in Canton, unfortunately. I assume it is from Plymouth, especially since I got the signal locked in so far in to Livonia last night.

 

The Canton area doesn't seam to get a 4g signal in the day. So do they tend to turn the power up after awhile breaking in the tower? Does the amount of people and bandwith available determine strength. Or, could it be a new tower having test done on it late at night? Just curious if anyone had any ideas.

In terms of signal strength during the day versus at night, solar radiation has a detrimental effect on other kinds of electromagnetic radiation. My understanding is that while the signal degradation is much more pronounced in different frequency bands (like how AM radio stations actually have to turn down their power output at night to stay within regulatory boundaries), the lack of solar radiation at night would allow a 1.9GHz signal to propagate an extra mile or two.

Ok so I did some investigative work.

The LTE that I'm receiving downtown Ann Arbor from mysterious cell ID 302 is tower DE03XXXX the one just south (and across 94) of Briarwood mall.

This speed test was from Briarwood but I still get about 2Mbps down at my house (State and Packard).

I had better signal though when I went to the parking garage at Thompson and Jefferson. That's a good 2.75 miles north.

Not sure if the State and Packard area is fed from the tower at Pioneer HS (Stadium and Main St.) or the water tower near Country Farm park, or a different tower all together. Anyone go near either of those to check on LTE availability?

Even though there are a couple of towers that are closer, all three Sprint phones in my house normally do connect to the one at Pioneer. Although, to get that LTE connection, I had to stand on the north side of my house and hold my iPhone as high in the air as I could... I couldn't connect to any LTE facing any other direction so that leads me to believe it was something north of me..

Field Test said I was connected to:

Serving Physical Cell ID 302

but, I have no idea which tower that actually is....

Kept cycling airplane mode at home and just got LTE for a minute before it dropped back out.

So at least some signal for downtown Ann Arbor?

I don't know if you all can view GIFs through Tapatalk but if so... (I'm a huge nerd )

I'm just a few minutes North of there, US-23 and Plymouth Road. So far, no LTE here. Dang it's getting close!

Well I first connected as I was getting onto 23 north from Geddes and held onto it until just before Plymouth

Living in Ypsilanti here, pic is broken when i look on Tapatalk.... anxiously awaiting, what's it of??

Stupid hosting sites.. I had an LTE connection at Geddes and 23.

Also, this morning, I was taking State St. south and picked up LTE as I crossed 94 (like by Briarwood). I made a left (so headed east towards Ypsi) on Ellsworth and held onto LTE until I hit Golfside.

So that's basically all of Ellsworth from State St. to Golfside.

If only I could have mapped that on Sensorly from my iPhone (although, I did write a very detailed email in French to Sensorly asking that they release an app for jailbroken iPhones -- or allow manual uploads via screenshots lol).

Look what I found this morning on the way to work as I was leaving Ann Arbor

I sure wish I could do more with Sensorly on my iPhone than just view existing coverage maps... C'mon Apple..

Once I was locked to an LTE signal, I held onto it until just past the Grand River exit in Brighton (exit 145.. a good 5.8 miles away as the crow flies). I wish I could have brought it all the way back to A2 with me!

** I'm hoping if I take the liberty of goading Apple ahead of time, I can squelch any further and/or more severe

After my failed LTE excursion to Howell two weeks ago, last night I decided to try again...

That's much more like it

In A2 is right!

I got excited hearing all of this LTE talk, so after work yesterday I detoured to Howell. I parked at the Livingston Commons strip mall and started seeing if my iPhone 5 would connect via LTE. I cycled airplane mode a few times (and even restarted a few times) but I kept experiencing the same behavior...

1) Phone would show 'Searching'

2) Phone would associate to tower and show the 'O' icon for 1xRTT

3) 'O' icon would stay for a few minutes, during which time it didn't seem like I had any connectivity whatsoever, and would then switch to 3G

Granted I know the iPhone's diagnostic screens are pitiful and I don't know from which tower I was receiving my EV-DO signal, but the speed tests I was running seemed like backhaul hadn't been touched yet.. Have a look at the screencaps.

I've never connected to an LTE site before so I can't rule out that it may have been a phone issue? While I was there I did do a service update as well with ##UPDATE# but it didn't make any difference.

Fantastic! Thanks, bollar, for the clarification

Not lock screen, the power off slider.

MacinJosh, are you saying to power off the phone to get the numeric signal strength to stay..?
