Columbia, PA | But what's that fiber carrying? Even if T-Mo is deploying fiber links to their cell sites, I want to know what kind of bandwidth these links are pushing. I'm all for cell companies getting fiber backhaul links, but it'd be nice to know what kinds of speeds they're actually pushing to the sites. | |

| Yes...so what? Voice is maybe 12 kbps per conversation, GPRS is ~42 kbps, tops. EDGE in my experience has been around 200 kbps. That still leaves a LOT of room for HSPA+, though if your reply is that it won't max out the spec, you're right. But it is an improvement. | |

Valencia, CA | Re: But what's that fiber carrying? Exactly.
Lets take the 'easy' way to list backhaul:
3 sectors x 200kbps (lets assume that we have 1 full data channel avail for simplicity) = 600kbps _minimum
3 sectors x 12kbps x ??? . Lets assume that its 100 for simplicity (consume a lot of spectrum). 3600kbps.
3xT1s should suffice for voice + data.
Proper backhaul between 3.6Mbps HSPA and 21Mbps HSPA shouldn't be that different in theory, as 3.6Mbps has multiple codes allowing at least 4 3.6Mbps connections at once, while 21Mbps will be more of a single connection at that rate.
I'd expect 100Mbps to be a requirement | |

You are 100% wrong in your results you mentioned for your road runner connection. The website telling you the results I bet you gave you the correct terminology, so please use it, do not change it.
SO for me and my RR connection: I get around 10Mbit/sec download, and 500Kbit/sec upload.
My FiOS connection on the other hand:
running 10s outbound test (client-to-server [C2S]) . . . . . 35.53Mb/s
running 10s inbound test (server-to-client [S2C]) . . . . . . 35.63Mb/s
and again:
Download speed 35060 Kbps
Upload speed 34842 Kbps
and again:

| Re: has to be a typo That ISP sounds like it might be fishing for people's info... too many grammatical errors on their site... no actually Q's in their 'FAQ'... no mention of where their service is provided... prices are crazy low...
If you live in a metro area you can typically get so-called "ethernet" service to your home or business from places like RCN, Comcast, Verizon, etc... it just costs you a g-damn fortune to get it and you typically will call it commercial service vs. residential. | |

| | | | | This has to be a type. I don't know of any Fiber-optic transport technology rated at 20mbps. Both SDH or SONET as it is called in the US and WDM gets transmitted in 10gbps wavelength, so 20gbps sounds much more reasonable than 20mbps. Even if the Carriers in the US, of which i am not sure about, make use of STM16 (US OC-48) that would be 2.5 gpbs, accomodating around 120 HSPA+ streams. | |

| said by Romney2012:said by Boomer86:21MB downstream, with 20MB fiber? How is that possible?? Yes, that doesn't seem right. That fiber backhaul would only support 1 user at a time at high speed. Maybe they meant 20 gbps as in GIGABITS and not megabits. Does HSPA+ support 21Mbs per USER or per SITE? I always assumed that the speeds were per site, not user because the wireless spectrum is shared...
So if you have 3 people standing next to each other all running speed tests at the same moment I just assumed that their speeds would be whatever the tower could do divided by 3... so in this case 21/3 per user or about 7Mbs? (understanding that 21Mbps does not yield 21Mbps thru-put, I'm just using it as a math example)
Re: the 20Mbps fiber links to the tower... it's my understanding that the speed between handset and tower is not necessarily the speed that you need for a back link--similar to how a 54Mbs wi-fi connection does not yield 54Mbs in actually throughput... so in that case a 20Mbps fiber backhaul sounds like it would support a 21Mbps HSPA+ link, plus many voice calls, etc? | |

| No, they meant megs. I'm 99% sure that back home towers have at most 3 Mbps running to them, yet I see 2-2.5 Mbps. So I wouldn't be surprised at all to see 'net speeds approaching 15 Mbps IRL, at least for the first three to six months. Beyond then things will settle around 6-0 Mbps, still respectable. Remember that historically even 3G techs haven't reached their full speed potential due to backhaul issues; at least T-Mo is getting fiber to the tower for easy upgrades later as the price o bandwidth drops. | |
