Getting on the Internet

If you live in the city, it’s very easy to get “high-speed” internet connectivity (meaning always-on, 1 Mbps or faster) – choose from the available (usually several) methods based on cost, speed, and reliability.

In the country, however, it’s not so easy – so let’s review the options:

Old acoustic coupler1.) Dial-up using a modem: not a realistic option. First, it’s not “always on,” it’s only on when you dial up, so there are a lot of things you cannot do. Second, the speed you can achieve is dependent on how far away your local telephone switching station is; maximum modem speed is about 56 kilobits per second, and, practically, you might be lucky to get half that. It’s OK for getting and sending “conversational” emails, but it can take a long time to download a webpage, simple document, or large picture.

Cable Modem2.) Cable or DSL: probably your best bet IF you can get it. You have to be within a certain distance of a telephone or cable TV facility, and most rural residents don’t qualify. Cable and DSL usually provide the fastest speeds and best reliability if you can get it, though.

Fixed Wireless Antenna on home3.) Fixed Wireless (also known as WISP for “Wireless Internet Service Provider”): Next best option, because you can get good speed and reliability without wires. The problems here are that not all WISPs are created equal, and not all places are served by a WISP. What WISPs do is set up towers with radios on them, then install a radio on your house (known as “Customer Premises Equipment” or “CPE”) to “talk” to the radio on the tower. If you are in direct line-of-sight to a nearby  tower, and the tower is operated by a good WISP, this can work very well. If not, it’s not  a good option. There is a coalition of WISPS called WISPA – you can check their website for a WISP near you – see the links to the right.

USB AirCard4.) Cellular (or Mobile Wireless): OK, but can get expensive. Cellular companies sell “Air Cards” – typically USB devices that plug into a laptop computer to provide Internet access via the cellular network. They used to be very slow, but “3G” networks now routinely provide better than 1 Mbps, and new “4G” networks may provide many times that speed. While an Air Card is designed to be plugged into a laptop,  you can also plug them into special routers from NetGear, Kyocera, Cradlepoint, and others to provide a more “normal” Internet connection (one to which you can connect several computers). Some of the cellular companies are selling routers with the Air Card built-in as a way of getting into the home internet market – Clear (the company that provides WiMax connections through Sprint) is one of those companies with their new “Clear Modem.” Several cellular companies (Verizon being the one I’m familiar with) are selling the “MiFi” device that creates a wi-fi hotspot from an internal cellular data card. Unfortunately, the MiFi devices I have seen don’t have an Ethernet port, which limits their usefulness.

Satellite Dish5.) Satellite Internet: OK, but introduces a problem called “latency.” Satellite internet is available anywhere you have a clear view of the southern sky, so it has been the method of choice for rural households for some time. The problem is that the satellite is over 35,000 miles away, and a packet has to go all the way from your computer, 35,000 miles up to the satellite, 35,000 miles back down to the ground, to the server you are “talking to,” and then the response has to travel 35,000 miles back up to the satellite and 35,000 miles back down to you, and all of that takes about a second or more. While a second doesn’t make much difference if you’re just browsing a web page, it makes using Voice over IP applications like Skype or gaming services like Xbox Live impossible.

Once you figure out which option is best for you, the company will set you up and you’re on the Internet. Now the fun begins…

The middle ground between Access Points and Point-to-Point

In the last two posts I have talked about high-power outdoor access points that you can connect to your router and provide WiFi connectivity across a wide area and about point-to-point links that can connect one point to another.

In many cases, however, you want some of each: an access point that can provide good wifi coverage for the buildings around the house, and something that can “pull” that signal out to another building 2 miles away.

I call that piece of equipment a “directional client” but there are really two very different devices that fit this category:

  • A high-powered directional WiFi adapter like the WiFire or the WiFiStation – these plug into the USB port of your computerWiFire adapterWiFiStation adapter
  • A directional WiFi radio that’s really the “client half” of a wireless bridge – for example, a NanoStation – that provides an Ethernet extension of your wireless network.

Here’s how it works: let’s say you have your Access point up on your house, but you need access for a computer or two out in the barn, and the signal just isn’t quite “loud” enough out there. You might just get a WiFire or WiFiStation, put it on the computer, and put the antenna in the window facing the house, so it will pick up the signal better. You might also mount a NanoStation on the outside of the barn facing the house, and then hook up the Ethernet port to your computer. If you have multiple computers, you can attach an Ethernet switch to the NanoStation and run Ethernet to each of them. You can also attach a WiFi access point (another PicoStation, or just a consumer-grade router) to the NanoStation to provide WiFi in the barn – just configure it as a “bridge.”

You may be surprised by how well this works – I have used a NanoStation to connect to a PicoStation 2 HP at well over 2 miles (hilltop to hilltop – nice, clear Fresnel zone).

It should also be mentioned that there are high-power OMNIDIRECTIONAL WiFi adapters – there is a version of the WiFiStation that is both omnidirectional and outdoor-mountable (so you can put it outside the barn or even mount it on a vehicle) and a variety of small USB adapters with big antennas on them (Alfa seems to be one popular brand, and Engenius has a nice one). You can also use a PicoStation or something similar in “client” mode just like the NanoStation. You’ll lose some “gain” because of the lack of directionality, but you won’t have to point the antenna at it – extremely desirable if you are mounting on a vehicle.

Next – on to the REALLY good stuff!
