Analyzing requirements: The foundation for a successful wireless LAN

ITworld.com |  Networking

  • Information security requirements, or the level of protection
    your data needs from particular threats. The degree of needed security depends on the
    severity of the consequences the organization faces if data is lost. Military and law
    enforcement agencies require high-level security. Other organizations probably require
    much lower levels. These requirements determine whether you should include mechanisms
    such as encryption.
  • Environment. Conditions such as the room temperature and
    humidity, construction materials, floor space, and presence and intensity of
    electromagnetic waves could affect the operation of the system. In most cases, you
    should perform a site survey to inspect the facility and evaluate the presence of
    potential radio-frequency interference.
  • Schedule. Identify any circumstances that will affect the
    schedule, such as the availability of funds, an urgency to see a return on investment,
    the availability of project team members, and the interdependency between this project
    and others. Spell out the schedule requirements so the team knows the time frames it
    must work within.
  • Budget. An organization may have a limited amount of money to
    spend on the wireless LAN. If you know the budget constraints, it's best to identify
    them in the requirements.
  • By defining these requirements, you'll have made a solid foundation for designing a
    wireless LAN. Next time I'll cover your next step: determining the components and
    configurations that meet specific requirements.
