In either case, such surveillance networks are used
to capture live video from many locations and stream the live video to a central
location.
Deployment of video surveillance and monitoring networks can be a costly proposition
when a large deployment is considered. RF wireless technology may not be able to provide
the kind of bandwidth required to aggregate all the traffic from a large number of surveillance
cameras, each generating ~2 Mbps of traffic. The alternative of laying cable to each
surveillance camera can be cost prohibitive, especially if it requires laying the cable under
public infrastructure. Optical wireless mesh is very well suited for such applications,
primarily due to the high bandwidth it can support.
Wireless Access Infrastructure Over the past several years, there has been tremendous
growth in the deployment of WiFi access networks. These networks may include
public networks owned and operated by municipalities as well as hotspots provided by
private enterprises. With the ubiquitous growth of WiFi networks, we have also seen
significant activity in the arena of WiFi mesh networks, where WiFi access points are
meshed by means of the RF wireless connections among them.
