3G Fixed Wireless For Business

We all know how 3G cellular wireless service has transformed the mobile phone into the smartphone. Did you also know there is a fixed wireless service available that uses the same technology? It’s a unique solution to getting business grade Internet access where everything else is too expensive or not available at all.

What the cellular industry has done is to build out a vast infrastructure of wireless base stations all over the country. You can think of these as a blanket of mobile phone coverage and you’d be right. You can also think of this infrastructure as a blanket of broadband coverage. You’d be equally right. The familiar cell towers are transmitting both voice and data signals on different channels through their microwave radio equipment.

On the data side, the 3G (3rd generation) wireless broadband service acts like a collection of Wi-Fi hotspots with much greater coverage and all linked together. You need a wireless modem aircard and a subscription to pick up this service. It doesn’t use the same channels as WiFi. It’s also not free, but for businesses the cost can be lower than other alternatives.

Many small and even medium size businesses use T1 lines that are available almost everywhere. Cost varies with location, but is typically several hundred dollars per month. Fixed wireless broadband can be had for half of that for a primary connection and even less if you only want backup service.

Unlike DSL and Cable, other SMB bandwidth choices, T1 and 3G wireless are available just about anywhere you want service. That includes locations that are off the beaten path if they can still get solid cell phone service. Fixed wireless is unique in that installation can be in a matter of days and you can have it installed at temporary business locations, such as fairs, conventions, and short term holiday stores.

Accel Networks is a leader in 3G fixed wireless for business. Their equipment and system are optimized for consistent bandwidth and high reliability. That includes proprietary RF optimization and RF level management and a proprietary antenna design that maximizes signal strength. This goes far beyond the simplistic design of the USB aircard modems you buy for mobile computing.

The other advantage of Accel Networks is that they have agreements with all three major providers (AT&T, Sprint, Verizon) to ensure extensive signal coverage. You know that no matter which carrier you pick, there are places where you’d be better off with one of the other carriers. It’s a matter of who has the most towers and channel licenses in a particular area. Accel picks the carrier that has the best signal at your particular business location. Since this is fixed service, it doesn’t matter that they’d make a different choice if you were located in another town.

What is 3G fixed wireless best for? Credit card verification is extremely popular. Accel Networks specializes in this technology and offers a layer 2 PCI compliant network meeting credit card industry requirements.

Most small businesses need credit card verification, but many also need general access to the Internet for Web browsers, email, and perhaps automated ordering, inventory, bookkeeping or data transfers between locations. Accel Networks managed broadband wireless solutions offer a minimum of 750 Kbps download and 250 Kbps upload broadband speeds. They also provide a Service Level Agreement (SLA) that includes 99.9% availability, minimum acceptable data rates, maximum acceptable latency, and mean time to restore.

Gigabit Wireless For TDM and IP Transport

What do you do when you need to get Gigabit bandwidth services into a building that has no fiber connection to your network? If you are XO Communications, you simply add a wireless hop using BridgeWave Communications FlexPort link. No stringing aerial wires on poles. No trenching fiber optic conduit. Just high bandwidth connectivity through the air.

We’re used to thinking of twisted pair copper and microwave wireless as the right solutions for moderate bandwidth needs. Gigabit bandwidth levels obviously require fiber optic strands, right? Not really. Point to point fixed wireless systems can give you fiber optic performance without the fiber or the optics.

I mention optics because there are laser based solutions designed to connect buildings at Gigabit levels. They are especially well suited for connecting networks between two tall office buildings separated by a freeway or river that makes installing fiber prohibitively expensive if even possible. But that’s maybe a thousand feet or so. How about when you need to link networks over a few miles line of sight?

This is the area where BridgeWave shines, so to speak. Actually, they’re using two-way millimeter wave transmissions in the 60 and 80 GHz radio bands. Those frequencies are high, but nowhere near the infrared or visible portion of the spectrum. Here’s something interesting, though. Oxygen attenuates signals in the 60 GHz band, a property unique to that portion of the spectrum. That limits transmission distance, but it also works to ensure that multiple users on the same frequency are unlikely to interfere with each other. The signal is simply absorbed by the air on either side of the narrow beam and past the receiving antenna.

If you’ve had a bad experience with RF links in the WiFi band or other microwave and UHF frequencies, you can appreciate both the interference avoidance and inherent security of the millimeter wave band. It’s likely that anyone trying to intercept a 60 GHz transmission would have to insert themselves in the path to such an extent that they would affect the strength of the signal at the intended receiver and give themselves away.

The 80 GHz band doesn’t have the oxygen absorption characteristics of the 60 GHz band, so it is better suited to medium haul rather than short haul links despite the higher frequencies. Still, the interference is minimized and security is enhanced due to the narrow beam width of the millimeter wavelength system.

The BridgeWave FlexPort80 link that XO is deploying is available in the 80 GHz millimeter wave band plus the licensed 18 and 23 GHz microwave bands for longer links. One of the attractive aspects of the BridgeWave equipment is that it is an all-outdoor solution. Some competing systems simply have an outdoor antenna with rack mounted transmission gear needed inside the building.

Another feature especially valuable for today’s corporate networks is the ability to transmit both TDM and IP traffic. The TDM capability is also being used by mobile carriers to backhaul their 3G and 4G networks from isolated base stations. It should be noted that FlexPort80 delivers simultaneous TDM + IP connectivity, making it truly a “flex port.”

Do you have a location that has been particularly difficult to supply with high bandwidth telecom services? Perhaps a combination of fiber optics and millimeter or microwave wireless transmission can get you the Gigabit connectivity you need at a cost you can afford.
