$10k to serve rural broadband have-nots
(old news - 02:48PM Tuesday Jun 20 2006)
tags: wireless · hardware
Digg users point to this YouTube video that explores setting up your own dual T1 wireless transmitter, provided you're out of range of other options and you've got an extra $10,000 lying around (plus the monthly cost of the BellSouth T1's). The owner claims his monthly power bill is only $11, since he used a lot of bottom-shelf gear in the implementation. We assume many of you WISP gurus would do this differently, so let's hear it!

Wow, this sounds great!

you'd only need 200 users paying $50 to pay this thing off. In the suburban/rural fringe I think this is very doable!

How fast is a T1 Line? Isn't it only 1.5Mbit?

Put only a handful of people on that at one time and you'll be cruising along at dial-up speeds. Am I wrong in thinking that, I'm not exactly a networking guru.

That's 1.5 Mbps symmetrical, and uncompressed.

Re: Wow, this sounds great!

My company currently has 900 users on a 10Mb sym. connection. We had those same 900 users on 3 T1s and access was completely acceptable. Typical usage was only around 3mbps down and about 1mbps up. The thing to remember is that most users just want to surf the web and get important things done. Unless you have a few bandwidth hogs on that system, 3mbps sym. for even 200 users would be acceptable by MOST people's standards. This is especially true when dial-up is the only other option.

Re: Wow, this sounds great!

I'll guess that your company isn't keen on people running P2P or pulling video streams while at work, so of course that degree of overselling would not be a particular burden.

You can't assume that in a consumer market.

Re: Wow, this sounds great!

I had 75 users + corporate email and web hosting on 6Mbps/608 for a while, and it was more than enough. I'm sure they could 'filter' down connections to give everyone 150kbps (3Mbps/200) if it came down to it. This isn't much different than Cable dishing out 8Mbps connections to multiple neighborhoods.

This is broadband in the forest, not in an urban market.

Don't you mean 15 kbps?
(3Mbps=3000kbps, 3000/200=15kbps)

Just because you, me, and most of the posters here use P2P a lot to share data and run video streams doesn't mean that everyone does. I will state again that for MOST users, this kind of bandwidth would be ample. I can name ten households I personally know that don't do either of these two things. All these people are intersted in is surfing the internet without the wait of dial-up, which this would be great for.

You could go with 100 users to pay off the equipment in a few months. $5000/mo income, - recurring cost of the 2 T1's at ~$1500-2000/mo, and the rest goes to profit and paying off the equipment costs.

Wisp

I've long dreamed of starting a wisp up north for those with no DSL or cable access. Starting capital is the only thing getting in the way I suppose :/

Go to a bank, have a good business plan, and get a $20,000 loan. There ya go. As long as you can prove that your chances for return are high (as they would be in any town of just a thousand or so people) and that the chance for the big cable or phone companies to provide broadband is low, you should be good.

You should also do preliminary research and see if anyone in your 'hood needs or wants the service.

Think here guys

Your going to sell a T1 to 200 people? Think logically here DSL and Cable is well over 5mbps to each user. As soon as something else became available customers would flock to another ISP. I worked at a WISP and we ran into the same problem.

Re: Think here guys

i never said anything about using T1s. there are a NUMBER of other technologies that can be deployed besides T1s.

I think its also good to remember that a lot of the COs in these rural locations are centrally located to the areas they serve. So if you locate your tower close to the CO, you could open up more possibilities for the backhaul.

I remember where I used to live before, the CO was jut couple of blocks away. if DSL was around back then or I lived there now I could probably be getting 8 down!

1. Only 1 uplink for the site? No redundancy?
2. Only 1 T1 for all customers?
3. Mail, DNS, HTTP, FTP, all on one server!
4. Server outdoors protected by metal box!

Wow, talk about bootstrapped.

#3,4 IMHO are just unacceptable. Should be separate (mail, DNS should be redundant on multiple boxes) and in a datacenter with backup power and physical security.

Yikes.

Ya, I could make a car with a couple of 2 x 4's and some wheels and maybe a lawn mower engine but I doubt anyone wants to carpool with me.

This idea is a customer service nightmare....not like i havent seen many of this in my day, but I always notice that some how they dont stick around too long.

Oh yeah they forgot to mention the pricing for CPE per customer. That is always the most often overlooked aspect that causes the greatest pain.

They're not trying to compete w/ Comcast, et. al

When you look at something like this remember... They're going places where the other providers have forsaken.

You can cry, complain and whine about loading 50-100 people on a single T1. You can fuss about it only being 1.5mbps. But when you have no other options, you'll gladly sign up. Remember, if you're out of range from the CO or not in a neighborhood where the cable company provides cable modem service, you're screwed.

Compared to satellite, this sort of service is a godsend to the people they have as customers. I lived in the Jackson, MS area for 5 years in one of those forsaken areas. No cable modem, no DSL. I paid out the butt for ISDN. The irony was that our apartment complex had FIBER to each complex from Bellsouth. But the ONU's Bellsouth had used in the installation back then could only handle POTS, ISDN or a single T1 per ONU. There was no DSL or ethernet card available for them. So we were stuck with no other choices. And the cable company was Susquehanha (sp?) [aka SusCom] Communications. They only offered 1-way cable modem service and that was iffy. For 3 years they kept announcing that "2-way cable modems are coming soon". But their cable plant was so crappy that it wasn't possible.

Now why they're hosting their email and such at the tower, I have no clue. It would have been much cheaper and more reliable to buy space at a web hosting company somewhere. Oh well.

PS... Remember, most wireless ISPs in Mississippi and other places in the south have a hard time using 2.4ghz equipment due to pine trees (the pine needle absorption/multipath effect). So if you're planning to do this around pine, you'll want 900mhz or 5ghz.

Re: They're not trying to compete w/ Comcast, et. al

The reason its all hosted at the site is because it gives more bandwidth to the customer to retrieve email and reduces look ups for dns.

It's meant to reduce the traffic load on the t1's. Not a bad idea but all the spam being spewed onto the t1 quickly negates this if the spam issue gets large for them.

Again, not everyone must have that 50Tbps connection.

If you are selling to business customers then 100 Users per T1 is more than enough. Businesses are in the business of making money not sharing files. I have a customer on a 15Mb pipe with over 100 remote locations, VoIP, VPN Tunnels, 1500 in house users, and a Data center with 250+ servers. And they don't use 50% of their pipe. It probably has something to do with the fact that they request that their employees work instead of watch videos or share files. Wow what a concept.

Costs

What kind of costs are associated with the T1 lines?
Would there be two separate costs? The actual line and then the internet connection? If I remember correctly Frame Relay is just a way of getting from point A to point B through a shared cloud?

Re: Costs

I can't speak for every place but T1s from Bell are expensive. They are paying at least $650+ per T1. If they are as rural as they seems to be count on $900+ per T1. There are much cheaper ways to get bandwidth to your towers. I think they stated they had other towers. You come out cheaper putting 3 or 4 T1s in a multi link in one location. Then from that central location feeding your bandwidth out to other towers wirelessly.

I have to commend these guys on taking matters into their own hands and getting broadband out in the middle of no where. They are not really doing it the right way, but they are doing it.
