Strategy: Building a wireless infrastructure

May 8, 2001, 02:10 PM —  InfoWorld — 

THE ADOPTION OF any new technology can be a nerve-wracking experience, both for the IT staff charged with doing the rollout and for executives writing the checks.

The key to making the right technology decisions and to making these projects go smoothly is to have a strong strategy and a detailed plan in place before implementing a solution. Preparation is even more important when building a wireless infrastructure. Because wireless products must, by design, touch many different parts of your enterprise environment, extra diligence is necessary to make sure all goes as planned. For example, if your enterprise network is built on Cisco routers and switches, you must make sure that the wireless base stations will interoperate correctly with them.

You don't necessarily have to use the same vendor for wireless as you do for your existing infrastructure, but if the components don't work together properly, you're setting yourself up for trouble down the road. Thinking about these interactions ahead of time can save time and money during the implementation and ongoing maintenance phases. Probably the most important factor to consider is whether the products you choose are supported by your network management framework, whether it be CA Unicenter, Tivoli, HP OpenView, or whatever your company's network management tool may be.

Technology step-by-step

1. Evaluate your needs. Talk to users to find what benefits a wireless network would provide. Take a hard look at the impact of adding wireless networking to your environment.

2. Plan for your wireless needs. Examine what wireless technologies best suit your particular needs. Planning ahead will help you avoid headaches and added costs in the long run.

3. Trial rollout. Once you've determined what hardware and software is right for you, do a trial rollout to check for problems that may seriously affect your long-term plans.

4. Testing. Have a team dedicated to evaluating your trial rollout. Take nodes offline, disconnect base stations, and give your new wireless network a test for problems you anticipate.

5. Training. When you're confident that all of the bugs and incompatibilities are worked out, it's time for training. The IT staff that must support this new infrastructure will need it.

6. Production rollout. All systems go! Phase in your new wireless solution throughout the company. Your IT staff can then dedicate time and resources to solving problems as they crop up.

7. Ongoing maintenance. Ongoing network monitoring and maintenance is as much a part of the equation as the original acquisition costs. Make sure your network management platform is monitoring the wireless network fully.

Before you begin planning your company's wireless strategy, take a close look at the wireless options available. Does your company need to provide employees with some type of wireless Internet access to corporate information while they're on the road? Do customers need access
