How to buy wireless communications
By Tim Dees
The term "wireless communications" encompasses any information that doesn’t travel over a wire or optical cable or on a piece of paper.
The wireless system should be capable of supporting evolving open standards for wireless protocols providing for licensed and unlicensed radio frequency bands, security, quality of service, client access and wireless system radio management. The system should be easy to configure and manage for both indoor wireless LANs and outdoor Wireless mesh deployments allowing users to manage the wireless systems from a common, centralized user interface capable of managing the entire end to end system. The wireless system should support multiple radio channels, standards and frequencies and state of the art security and quality of service protocols for unlicensed and licensed radio bands and allow hybrid deployments using dual radios for uplink, access, bridging and mesh applications, as well as point-to-point configurations or point to multi-point.
Listed below are key points to consider when purchasing wireless communication equipment:
1. Establishing Bandwidth
4. Cell Phones
An enhancement to either system is a mesh network, where the wireless transceivers in the patrol cars can act as access points for all the others. This allows for extending beyond the usual area of operation, and are "self-healing." If one access point goes down, the others will continue to work so long as they’re in range of one another.
