Technology is rapidly evolving. Thanks to a relatively new low-power radio frequency communications technology, wireless mesh networks, security systems are becoming that much more reliable, efficient and cost effective to deploy. These wireless mesh networks, originally developed for military applications, are comprised of a series of nodes or transceivers, which are communication devices that can both receive and transmit data to each other.
Nodes transmit data in a non-linear fashion, meaning that instead of a node simply transmitting information to the same node each time, it is continually monitoring all nodes within its surrounding perimeter and searching for the shortest and highest quality path through which to communicate a message. If, for example, the node it had previously sent a communication through were to go down, it will scan for an alternative node through which it can transmit a message. This self-healing attribute allows a network to continue operating even if one or several nodes go down. This improves the overall reliability and performance of a system.
Traditional network deployment within buildings and, more importantly, between buildings has been accomplished with hard-wired network infrastructure. The latter case typically involves trenches and laying fiber optic cabling. With wireless mesh technology, inter-building networks can be deployed for a fraction of the cost.
Within the last few years, new wireless standards have come out, such as the 802.11n and the 802.11ac, which increases the amount of information that can be received and transmitted to over 1 Gbps. This increased bandwidth helps to ensure that important information is being transmitted and received in a timely manner, so when something does occur, it can be managed efficiently and effectively.
