Internet Gateway: Â Finding Fiber
Youâve found your market, they want broadband, and you’ve identified some good tower locations to get service to their homes. Â Â Now you need to secure a high volume of quality broadband Internet to your towers – but how do you do that?
The first step is finding the closest fiber âpoint of presenceâ (POP). Â Â This is a location where you can âco-locateâ (ie. place your equipment) that has access to a nationwide fiber backbone. Â Â One important caveat – you need real dedicated fiber here. Verizon FIOS or Comcast Xfinity are both delivered over a fiber optic cable, but they arenât dedicated. They are built on a shared technology called GPON. Â For more on this, as well as an explanation of why cable modems, DSL, and âbusiness Internetâ wonât work for gateway – see our article on Non-Dedicated Gateway.
The best place to obtain fiber is a data center, as they will usually have several providers to choose from so you can get a great rate. Â However, if youâre in the middle of nowhere (the best place to be a WISP!), you probably donât have access to one nearby. Â Â The next best place to check is large hotels (see if management can tell you where they get service), or large office towers. Â If you donât have any of these options then youâll have to build wireless âbackhaulsâ to get it out to you.
Swift Fox has a big list of locations and pricing for various fiber providers throughout most of the US and Canada, feel free to contact us and we can help find the options closest to you.
Knowing the Lingo: Â What to ask for
When youâre shopping around for wholesale Internet, you have to be very specific that you need a Dedicated Internet Access (DIA) connection. Â Other terms for this are âunmetered gateway with 95th percentile billingâ, or âdedicated ethernetâ. Â Â These connections will usually be priced by the megabit, and should always be âunmeteredâ, which means that you can never have a transfer cap (eg. gigabytes per month).
If youâre just starting out, you will want to obtain at least double the highest package you plan to offer (so get a 50mbit gateway if you offer a 25mbit package). Make sure that you pay close attention to contract terms because if you grow quickly you’ll need to get this increased pretty soon.
First Place To Look: Â IXPs and The Big Guys
There are companies out there that only sell service to ISPs. Â Â They will know exactly what you need, and can usually give you an amazing price (eg. $1 per megabit/s or far less). Â Â The catch is that these outfits only have availability in large urban centres, usually at a place called an âIXPâ or Internet Exchange Point.
If youâre fortunate enough to be on the periphery of a large city, you may be able to negotiate a rooftop lease directly with the IXP, and connect your network directly to the Internet backbones there. Â Â This is very cheap, and extremely fast. Â Â At an IXP you can also often connect directly to large media providers like Youtube and Netflix, so that you can pay a much lower rate for that traffic and it doesnât go over your main gateway.
To get a list of locations that are eligible for this sort of connection, a good place to start is this list from Hurricane Electric. They are in limited locations but these will always be the most major data centres, and if you can go with them they’ll often be the cheapest option.
An Easy Option: Â Dedicated Fiber Service from a Cable Company or Fiber Provider
Many cable companies are quite willing to sell you dedicated Internet gateway. Â This will usually cost quite a bit more on a per megabit/s basis than the big ISP-only providers, but when youâre first starting out it can still be a good way to go.
Youâll need to meet the cable company somewhere where they have dedicated fibre access, usually large hotels, office buildings, etc. Â Negotiating with the owner of the building to co-locate antennas on the rooftop will be necessary.
As You Grow: Â âTransportâ from the local Fiber to an IXP
If you canât connect directly to a major IXP, you might be able to get there in a roundabout way. Most cable companies will sell something called âIP Transportâ over their network.  This lets you send your traffic over their fiber, but doesnât give you an Internet connection from them. Essentially it gives you a port at your local cable companyâs network in town somewhere, and another port at a data centre in a major urban centre – and your traffic just goes in one end and out the other.
The advantage of this option is that you can buy a much larger volume of “transit” (Internet Access) at an IXP, and then buy transport from various network locations to get there.  You may have to install equipment in a city that could be a distance away, but the cost savings are usually well worth the extra hassle.  Sometimes the company you obtain gateway from already interconnects with your cable company.  Usually this route only saves money once you are large enough to need a 10 gigabit or larger main connection.
Usually Avoid: Â T1âs and the Incumbent Telephone Company
One option for dedicated Internet gateway that is available pretty much everywhere is the T1. This is a very old-school method of securing broadband, which gets you exactly 1.544 mbit of service over a single phone line. Â Â You can âbondâ multiple T1âs together to get more speed but this can become seriously expensive. Â Â It is also is not really scalable, as your top speed is limited by the number of phone lines that come into your location, and you canât go above it.
In every instance that weâve worked with a WISP to obtain gateway from the telephone company itâs been very difficult; loads of hidden fees, outages, and poor customer service. Â Â We recommend you steer clear of the phone company if you can, unless they’re the only option.
Bonding or combining together DSL services has similar issues. Â It is not generally a workable solution for a successful ISP.
Bridging the Gap: Â Multiple Hops with Relay Towers
If you donât have an option for dedicated fiber connection where your market is, take a good look at how many towers you might need to reach an urban centre that does. Â If you can keep each tower less than 25 km / 15 mi apart from each other with good line of sight, you can usually set up a pretty solid backbone of your own.
Youâll still want to minimize the number of towers between you and your gateway, because every one of them will be a single point of failure that could take down your whole network – but built correctly, itâs still a way to get a one up on your competition by being able to bring the fastest service first into your market.
