ATX4G

4G LTE downtown Gardner mass !

no no robert... wifi settings are seperate and should have nothing to do on how it receives and plots a 3g or 4g signal. i'm not having upload issues, i'm having capturing issues. if a 4g signal is present and the phone is currently in 3g mode it will not list a point under 4g unless the phone actually receives a strong 4g signal for an extended period of time, enough for the phone to actually switch the icon from 3g to 4g and then it will start logging the 4g points. when the phone is in 3g mode it will log 3g and miss the 4g spots, when it's in 4g mode it will log both 4g and 3g. if you look at the maps the 4g lte points are off a little.

i'm having difficulty even finding a decent lte connection, most attempts to do a speed test fail. at this point in time, no live lte in austin is strong enough to give me a connection so i can attempt a speed test while driving down the road at 70mph. that's the real test if you ask me.

anyone else having issues with sensorly? i logged a 50 mile journey travelling thru all of the already marked lte zones, and not a single lte spot was recorded on my phone. i stopped the car, and toggled airplane mode and bam, 4g. once i started driving it switched to 3g. i was able to do a speedtest in a 4g zone and got .26 down and .07 up. what's wrong with this picture??

thanks for sharing the porn

so riddle me this, which tower is confirmed active then? i thought i found the towers that were "hot" , they have lte antennas and sensorly confirms the signal. when i go to a spot where lte was confirmed and do a speed test i'm getting no where near the same results. i've updated my roaming list, rebooted the phone, it's in lte/cdma mode, just can't figure it out.

robert i'm frustrated because i've been so excited about lte towers coming live in the austin area. now i'm finding lte everywhere but it's super slow. here's my speedtest results:

lte:

.87 mbps

.80 mbps

.02 mbps

.28 mbps

3g:

2.31 mbps

1.77 mbps

1/24 mbps

WHAT GIVES??? if i look at the sensorly map and go to where a lte connection was reported, i have to stop my car, put it into airplane mode, wait, then switch back and THEN i'll see the 4g icon. once i start driving it will switch from 4g to 3g and will not switch back. are these lte sites not turned on fully?

is there a setting on my phone that's not correct? i'm pretty tech savy, just not sure what the heck is going on. it's sad my girlfriends wi-max S2 blows away my lte S3.

i tried to post from my S3 earlier and when i hit 'add comment' the button highlights and does nothing, very frustrating!! SO what i was going to say is that i was driving around south austin for a white earlier today. someone correct me if i'm wrong, but i think the LTE signal came from the sprint store that is at mopac and 290 w. there are a few towers in the area, including a sprint tower across the street but it wasn't on the list for a tower to have LTE work done. i drove over there anyways and confirmed there are no lte antennas or recent work done to the tower. the other tower is an at&t tower. i drove around using sensorly and did some more lte plots. the lte signal was very weak and would only last a few blocks. i did a speedtest and it was less than regular 3G ! my girlfriend S2 got 18mbps on what i call 3.5G or wimax. i feel like i own a ferrari without a motor, it looks pretty but doesn't go anywhere. i now regret chosing sprint.

Sorry for typos. I'll edit later. I'm at the park pl cir tower and I have logged 28 points of 4G on sensorly. We have a live one boys !

After reading the last post I decided to go for a drive. While northbound on 35 just before 620 my 3g icon went to 4g for about a mi Ute and disappeared. I am logging with sensorly now.

copy and paste this into google maps and zoom in. you can see they were working in the site with a truck in the driveway. i have a hunch this is the tower the LTE came from. 2250 1/2 Park Pl Cir, Round Rock, Williamson, Texas 78681

Go into settings and then "about" phone or phone info (usually near the bottom settings). You should then see info on software and hardware. Look for PRL within those menus.

 

I tried to use the hacked Verizon-only prl (00001) and it connected me to MetroPCS not Verizon? I think it might be because where my house is the signal for Verizon is weak and MetroPCS is stronger?

 

I can't wait for the LTE manufactures to release an all frequency LTE chip that will allow roaming on any LTE network nationwide (or worldwide). I had read a few months back that they were about to release such a chip but then I didn't hear anything else about it? It's crazy that we won't be able to roam on LTE like we do on EVDO.

thanks, it says i have PRL 25006

how do i know what PRL my phone has? i did an update yesterday and it said it's up to date.

What does Part 15 have to do with this other than stating a P15 device cannot cause interference, and has to be able to accept or reject outside interference?

you'll have to live with the radio in the car picking up the interference. unless you can re locate the snapshot device or put some ferrite chokes on the input power wires and antenna in connector.

i remember getting bleed over from an old GTE mobilenet cell tower, you could hear the control channel in the 870MHz range blasting into an old fm stereo whenever you would swing the tuner to 108 MHz. here's a sound clip: http://www.kb9ukd.com/digital/cellular.wav

it all comes down to part 15 of the fcc rules. the cell phone is a transmitter and when a device, say a pair of amplified computer speakers is near, it will act as a receiver and sometimes you'll hear the phones handshake to the tower. when i have my phone next to my laptop and my headphones are plugged in i can hear the handshake and know when a call or text message is coming in before the phone even alerts me.

who knows their cell towers? i've noticed a ton of existing cell sites that have shiny white new antennas on them, i'm finding that the majority of AT&T sites have a bright steady green LED at the top, i guess to signal to the techs on the ground that the top is working correctly? anyways i found a sprint tower tonight in north austin. it appears they are still working on it, tools and equipment, bags, etc left outside (strange if you ask me) however one thing i did notice is there was also a green light at the top of the pole near the antennas cept this one was flashing. is there any way to tell a sprint tower from a verizon tower or at&t tower? t-mobile has their signs all over the front gate on theirs with a site number that starts with AU for austin.

are you using some sort of net monitor app to capture and alert you that you were on an LTE network or were you looking at your phone / toggling airplane mode, etc to watch it happen? so far nothing in austin yet. I wish i had a tower list for southwest austin. i know of one at mopac and william cannon and it doesnt appear to have any new whiter antennas with 4g box radios near the sticks. also what's a good monitoring app to log LTE connectivity and alert you? I think i've tried them all but havent found one that i like.
