Disclosed is a remote network management system for coupling a series of remote domain servers, file/print servers, headless servers, network appliances, serial IT equipment, switches, routers, firewalls, security interfaces, application servers, load balancers, and environmental controls to one or more user workstations allowing for selective access of the remote devices. The remote devices are all connected to a remote management unit which interfaces each user workstation to the remote devices. The power supply of each remote device is similarly connected to the remote management unit through a controllable power supply. An option menu containing a list of all of the remote devices allows a user to select and operate any of the remote devices from the workstation. The option menu is also utilized to selectively control the power to the remote devices, servers, and computers.

A TDOA (time difference of arrival) location system, in which mobile wireless devices broadcast wireless signals which are received by two or more transceivers deployed in the vicinity of the mobile wireless device. Each transceiver measures the TOA (time of arrival) of the received broadcasted signal and reports the TOA to a central server. The central server then calculates the mobile device position using multi-lateration of TDOA values. The system uses fiber optic links between the antennas and the transceivers deployed in the location area to provide unique advantages that couldn't be achieved using RF coaxial cables.
