WIFI wireless networking

Wireless networking is used to meet many needs. Perhaps the most common use is to connect users who travel from location to location. Another common use is for that connect via satellite. A method is a logical choice to network a LAN segment that must frequently change locations. The following situations justify the use of wireless :

  • To span a distance beyond the capabilities of typical cabling,
  • To provide a backup communications link in case of normal network failure,
  • To link portable or temporary workstations,
  • To overcome situations where normal cabling is difficult or financially impractical, or
  • To remotely connect users or networks.

Developers need to consider some parameters involving Wireless RF technology for better developing wireless networks:

  • Sub-GHz versus 2.4 GHz frequency trends
  • range and battery life
  • Sensitivity and data rate
  • Network topology and node intelligence
