At the main gate to the factory where you work, there is a little security cabin. until recently, there was no requirement to deploy much in the way of networking components to that area. however, now it is a requirement that the security staff log traffic in and out of the site by using a number of networked devices. you anticipate the need for a wireless access point, a number of handheld devices with wireless network cards, and some other minor peripherals. there is currently no mains wiring at the cabin, and it is not cost-effective to install any - although there is a utp connection point in the cabin. what technology could you use to enable the devices you envisage needing?
