The quality of your uverse service has everything to do with distance. Once the Uverse signal is transfered from fiber to twisted pair to the prem the distance is allocated for to provide you with an appropriate speed profile. The distance also will factor in how many hd streams you recieve, be it 2, 3, or 4. There will be more packet loss over 3,000 feet than 500' given both lines are of the same quality performance.
Again, NO, the quality of the signal has absolutely nothing to do with distance. The person at 500' ends up receiving the EXACT same IPTV stream as the person at 3000' (barring any hardware problems with the equipment or the lines).
This is not an analog cable delivery system where the analog signal degrades while it propagates down the cable. This is an IP network. IP networks, by design, deliver packets to the receiver with no packet corruption, and ideally, no loss.
The system works just like on an Ethernet network: the person plugged into the switch with a 15' cable has no difference in the packets he receives from the person on a 300' cable run.
Any actual bits that are received in error by the VDSL modem are corrected due to the forward error correction algorithm in the modem. All components in the routers and modems are optimized and buffered as well, preventing packet loss.
Please stop posting your estimation/guess of how the system works. There are many things that you're obviously not familiar with, and your posting of incorrect information is not helpful.
I am not guessing and I could make the same assumption regarding your opinions. Im just stating facts trying to help out other viewers not trying to argue with someone who apparantly likes to argue to feel more important about himself.
The person at 500' is on a 32mg profile and the further your distance between the vrad and prem the lower your max attainable rate gets. As the max attainable rate on your line drops the higher the capacites get on your line which effect downstream and upstream bitrates. Hence as I mentioned before the limiting hd streams as your distance is increased.
Yes these ip based designs were implented to prevent packet loss but distance WILL effect it. Verizon Fios is an all fiber system however Uverse isnt and distance limits the availability of Uverse so you shouldnt post your estimation/guess of how the system works.
Again the quality of the lines are more important than their distance, and that goes the same for the in home networking quality as well.
