Some computer manufacturers are eliminating IEEE 802.11b protocols, claiming that it will improve 802.11g.  Since 802.11n is the fastest WLAN standard, why have any legacy Wi-Fi at all?

You need a, b, and g, because not all hot spots are running n. For example, if you’re operating an MQ-1 Predator by a wireless control system, while sipping a Frappuccino at Starbuck’s (you have your fantasies; I have mine), your computer better accommodate legacy Wi-Fi networks.  If you know that your computer will be solely dedicated to a network that only supports 802.11n, then you don’t need connectivity for the older standards.

By the way, when you use your computer to conduct major combat operations from the local coffee house, be careful where you sit; data throughput dramatically decreases the further away you sit from an access point.

Long-lasting battery power, light weight, and good wireless connectivity are capabilities often demanded by forward-placed warfighters for their rugged computers. GCN’s (Government Computer News)  “Rugged Computing on the Aircraft Flight Line”  describes how these features are also critical for the maintenance of jets, an activity not usually associated with the front-lines.

GCN does a good job of explaining how application requirements should drive the specs of a computer. For example, one Air Force base uses tablets with scanning capabilities, so that work control documents can be scanned while maintenance technicians were still on the aircraft. This saved time and increased productivity.

Since AMREL does so much customization, we are accustomed to the kind of analysis displayed in the article, i.e. examining an application’s requirements to determine a computer’s specs.  For examples of fashioning a computer to an application’s needs, visit AMREL’s Customized Solutions.

Mobile_mesh_networkAt AMREL, we see a lot of other people’s mistakes. Clients frequently come in with tales of woe, asking us to clean up messes made by them or their previous customization company. Some errors are specific to the customization process; others are true for rugged computers in general.

Of course, we’re happy for the business, but we think a little bit of knowledge can save everyone a lot of headaches.  So, before you begin your journey through customization, take this short test to see if you’re ready.

Part One: True or False

Please indicate which of the following statements are true.

1) Mean Time Between Failures (MTBF) is a valid way of comparing quality of parts from different companies.

2) Customizations must be done by third parties.

3) The manufacturer’s warranty never includes customization.

4) Low-volume customizations are too expensive to be practical.

5) The warranty and purchase price reflect the true cost of the computer.

6) A signed obsolescence agreement with your vendor ends your worries about End of Life issues.

7) No such thing as “Customized COTS.”

Part Two: Name three wrong things the narrator did in the following story

“I needed a customized application for rugged computers. It was quite tricky.  My team sat down, created a solution, and wrote the specs for it. We weren’t sure which rugged computer company to use, so we picked a large one, assuming they had the best capabilities. They explained to us that our specs weren’t practical. For one thing, the solid state hard drive required by our specs was much more expensive than we expected. We had to eliminate some of our wireless capabilities and other features in order to meet our pricepoint.”

Part Three: In one word, what is the most important thing to look for in a supplier of customized rugged computers?
