Distance from Tower claim

I am 5.5 miles from a CLEAR tower, have Line of Sight, and have an antenna with great signal strength: -61 rssi, 26 CINR. My upload speed is great, but my download speed is horrible, usually around .2 MB/s.

CLEAR tells me that it's because the tower is too far from me, and it takes a "while for the data to travel 5.5 miles."

Is there anyone out there with good service beyond 5 miles from a tower? It seems to me that with the consistent good signal I'm getting, my performance should be better.

Any feedback would be appreciated.

As long as you're getting a continuously good signal the distance should not matter, as RF travels through air at nearly the speed of light.

Are you connected directly to the Modem? If not, try doing that.

Are you watching streaming videos? The system will limit your speed if you download too much.

Or just too many people on your tower.

Your signal numbers look very good. Any chance of pointing your antenna at a different Clear tower? I have two that I can pickup, one is loaded more then the other with users. As more users download your speeds will be reduced, like p110011 said.

There are other towers, but this one is the strongest. I've connected to others with similar performance. At first CLEAR said the tower was congested, but now they're admitting it's not so bad that my numbers should look like they do.

I've plugged my equipment directly into the hub, and get great performance 10 miles up the road.

They're looking into it again. I think they have tower issues out here. They've seem to have stopped the "5.5 miles is too far" claim for now....

thanks for your input

Distance does not appear to be the issue. I am over 5 miles from the tower with lower signal strength and quality. Your numbers for cinr and rssi are great are much better than mine, but my speed is very acceptable. (10+ on average D/L). As Xrayman suggested in his post, try another tower and see if you have the same issue there.

How long have you been a Clear customer? If you are very new (Less than a month) it is highly unlikely you are being throttled for usage. But if your tower is overloaded, the length of your subscription will not matter. Try to see if you can connect to a different tower (regardless of signal strength) and rerun any tests.

I have been with Clear for 2 years. At 5.3 miles from the tower, I have consistently averaged over 10mb DL, but I know I am in a “fringe” area so I have kept some screen prints of prior speed tests. This spring a severe thunderstorm affected the tower I connect to. I dealt with 0.10 - 0.20 mb DL speeds for a few weeks before I could convince them that the issue was not my distance from the tower. I had a local tech come out to my driveway and leave me a message that he could not get a signal at my address and therefore there was no problem. Luckily, his call back number showed on my phone and I was able to talk to him. He was a very decent guy and I sent some screen prints showing prior speeds. That convinced him to check further and it wound up being a hardware issue on the tower.

Someone should educate this nut. The speed of light is 186,000 miles per SECOND. Even at 90% C, 5.5mi takes nanoseconds.

There's something wrong with that tower or the backhaul to it - period. (could be serious oversubscription, or haywire throttling.)

I pretty much agree with what you said. Just wanted to add that there could be errors due to noise causing retransmission.

How would one check for noise causing transmission? Could I somehow have a defective antenna or cabling? I thought if the antenna was bad I'd have poor signal strength....

Your RSSI should give you an indication if there is noise or not.

So with an RSSI of -62 noise shouldn't be my issue

And your CINR looks good too.

I'm also 5.5 miles or so from the only in-range tower. I get 20 CINR with a single 16dB panel antenna used inside the house wall. Have you used over 10-15GB in the month so far?

- You said your upload speed is "good", is this going from a download or a speedtest? If you're going from a speedtest, is it testing exactly at 1.0Mbps (or 1.5Mbps, depending on plan), or does it test inconsistently and often well above the 1.0mbps at some odd amount?
I've found that my upload is always consistently 1.0 Mbps if I am not managed. But, if I'm "managed", it will show up with a higher and less consistent upload. For instance, right now I tested at 0.63mbps upload, followed by a test at 1.14mbps upload, followed by 0.8. At the beginning of the month it will test between 0.98 and 1.02 upload consistently for me. If you call in to tech support again you should ask them to see if you were managed. They used to be able to tell you if the modem was managed and at what days/times, but they had to transfer to a different representative who only dealt with that, I think they used to call it a "speed specialist" or something else stupid -- This "speed specialist" started out the call pulling up the account and then immediately reading from the TOS section about bringing all users on the tower to a "fair speed"(ie. punitive throttling of just you if you've done more than check email) during times of "peak use"(24x7). It was Jan last year last time I called, so they could have changed policies again back to denying that they throttle anyone like they used to.

For an example, I am usually managed for the rest of the month (seems through 31st of month, but not definite... when I notice it I go to my DD-wrt router and it seems to have a very round 10/15/20/etc GB usage from 1st of month) after using 15GB or so U+D, but only to ~2mbps/1.5 avg until about 25GB or so then it cuts to 0.7mbps. Although, month before last they let me use 45GB before it cut me below 2 -- but that was followed by 2 weeks of punitive 0.2mbps 24x7 with no usage at all. Of course the speed you're managed to depends on how crappy the backhaul is on the tower you're connected to and how oversold it is..... I think they have not increased backhaul here but they've likely lost so many users that there's more relative capacity for now. It used to be much worse here, straight to 1s and even drops packets rather than just a smooth throttle to a lower speed.

Luckily I have a Sprint SGIII with LTE as a backup that gets 15Mbps/5Mbps and lower ping for the 5% downtime I expect with CLEAR (usually the CLEAR tower actually goes down hour+ several nights a week around 10PM or midnight... still broadcasting but won't authenticate any modems), so I use Clear for only webpages and last week started using Amazon unbox instead of netflix, and unbox will download to HDD. Sprint needs to just let CLEAR go bankrupt instead of planning to use them to supplement their LTE coverage....

I've used more than 15GB in the month, but when I drive closer to the tower I get 14 down. Heck, at my mailbox I get 10 down, but that's a 1/4 of a mile away from my house.

Clear finally told me my issues were NOT related to congestion, but they say there are no issues with the tower either.

I cannot understand how I can have such good signal numbers, and have such poor performance compared to 1/4 mile down the road....

Thanks for all the info.

Hey WacoUser, it seems like you are being affected by the NMS system buddy, The high upload and crawling download is tell tale sign of your issue, this is not related to signal nor distance as I have done Antenna runs for up to 7 miles... Either your tower is being managed or you are!

From my mailbox (1/4) mile from my house I get 10 down.

I'm beginning to wonder if tree leaves aren't part of my issue.

There's literally nothing but air directly between my antenna and the tower, But that path is closely bordered by leaves. If I moved the antenna one foot to the left or right leaves would be blocking LOS. I didn't think leaves would have that kind of impact on performance if the signal was good, but I'm quickly running out of options.

Thanks for the feedback. Your responses encourage me to keep trying.

Having the same issue here in Lubbock 1-1.5 miles from the tower. Below is the poop from the modem. I have downloaded a few gig this month so maybe they are managing me but hell this is dialup speed.

were up in lubbock now. Hope they fix you up I know how it sucks.

Thanks for all of the info. I'm wondering if I'm being affected by the Fresnel zone. Since I can see the tower, but that LOS is closely bordered by leaves near the antenna, I'm going to do some trimming and see what happens....
