UH ATT Lab Network
The UH ATT Lab's local area network has 16 workstations (room 110-H) with wireline and wireless connections to national and international fiber networks such as LONESTAR and Internet2, connections to the Internet and to the College of Technology's campus-wide internal network (room 110-J). The connection to Internet2 and the Internet allows us to broadcast events to the world either with our videoconferencing equipment or stream live video as well as allow users access to the Net. The College of Technology (COT)'s internal network connects 6 locations that include three research laboratories, the Wireless and Optical Networking Research Laboratory (WON), the Intelligent Sensor Grid and Informatics Laboratory (ISGRIN), and the Testbed of Smart Sensors Laboratory (TOSS), the Computer Networks Laboratory, Lab Management (Network Management), and the UH ATT Lab.
The UH ATT Lab's wireline Internet connection is through the University of Houston's UHNet OC3c. The UHNet's network provides 100 megabits per second on the backbone and 10 megabits per second to the desktop. For more information about UHNet's network visit the Information Technology Current Internet Connectivity webpage.
Our wireless Internet connection is through UH VPN Wireless access points located in the College of Technology (T and T2) at a maximum speed of 1.3 megabites per second, enough to handle most digital video streams. For instructions on how to login visit the Information Technology's Connecting to UH Wireless webpage . In addition, connection to the Cingular HSDPA 3G wide-area wireless (BroadbandConnect) using a laptop with broadband card has been successfully tested in the lab at speeds of up to 600kbps.
The wireline connection from the UH ATT Lab to COT's internal network is accomplished in three ways: one fiber optic 1-Gbps trunk, two DS-3 trunks to the Technology's SONET OC-3 ring using Cisco 7400 and 2800 series MPLS routers and a Fujitsu FLM150 optical switch, and several DS1 trunks to DSU/CSUs to the SONET OC-3 ring via the optical switch.
The Lab's wireless connection to the CoT's internal network is possible with the Bitrage's CR45A microwave radio system. It transmits and receives at speeds of up to 45Mbps using unlicensed frequencies between 5.2GHz and 5.8GHz. This system is mainly used as backup in case of wireline network failure.
