advantage of wireless technology

Wireless networking is used to meet many needs. Perhaps the most common use is to connect laptop users who travel from location to location. Another common use is for mobile networks that connect via satellite. A wireless transmission method is a logical choice to network a LAN segment that must frequently change locations. The following situations justify the use of wireless technology:
• Can span a distance beyond the capabilities of typical cabling,
• Can provide a backup communications link in case of normal network failure,
• Can link portable or temporary workstations,
• Can overcome situations where normal cabling is difficult or financially impractical, or
• Can remotely connect mobile users or networks.

Wireless networks offer the following productivity, convenience, and cost advantages over traditional wired networks:
• Mobility: provide mobile users with access to real-time information so that they can roam around in the network without getting disconnected from the network. This mobility supports productivity and service opportunities not possible with wired networks.
• Installation speed and simplicity: installing a wireless system can be fast and easy and can eliminate the need to pull cable through walls and ceilings.
• Reach of the network: the network can be extended to places which can not be wired
• More Flexibility: wireless networks offer more flexibility and adapt easily to changes in the configuration of the network.
• Reduced cost of ownership: while the initial investment required for wireless network hardware can be higher than the cost of wired network hardware, overall installation expenses and life-cycle costs can be significantly lower in dynamic environments.
• Scalability: wireless systems can be configured in a variety of topologies to meet the needs of specific applications and installations. Configurations can be easily changed and range from peer-to-peer networks suitable for a small number of users to large infrastructure networks that enable roaming over a broad area.


Handheld wireless radios such as this Maritime VHF radio transceiver use electromagnetic waves to implement a form of wireless communications technology.
