Austin, Texas, with a little over 820,000 people, is home to several centers of higher ed, the Southwest Music Festival, and a next generation network known as the Greater Austin Area Telecommunications Network (GAATN).
It was also the second metro area selected by Google for the Google Fiber deployment. But before they got Google Fiber, a local partnership had already connected key community anchor institutions with limitless bandwidth over fiber networks. The network measures its success in terms of cost avoidance, and averages out to a savings of about $18 million per year combined for its 7 member entities.
In 2011, the National Association of Telecommunications Officers and Advisors (NATOA) named GAATN the Community Broadband Organization of the Year. Today, GAATN also serves the City of Austin, the Austin Indepedent School District (AISD), Travis County, local State of Texas facilities, Austin Community College (ACC), the University of Texas at Austin (UT), and the Lower Colorado River Authority (LCRA).
GAATN's bylaws prevent it from providing service to businesses or individual consumers. Texas, like 18 other states, maintains significant barriers that limit local public authority to build networks beyond simply connecting themselves. As a result, local entities must tread lightly even if they simply want to provide service for basic government functions.
Decades ago, Austin obtained an Institutional Network (I-Net) as part of a franchise agreement with a private cable company, Cablevision. At that time, AISD used the I-Net for video and data transmission, with frequent use of video for teaching between facilities. In the late 80s, the district experienced large growth, which required adding facilities and phone lines. Phone costs for 1988 were estimated as $1 million and the 10 year estimate was $3 million. In 1989, AISD hired a telecommunications design company to conduct a study and make recommendations. JanCom recommended a 250 mile fiber network connecting schools. The network was expected to pay for itself in 10 years when only considering the cost of phone.
During this time period, Cabelvision sold off its assets in the Austin area to Time Warner Cable. TWC kept rising the cost of mainentance of the old coaxial I-Net until estimates reached $500,000 per year to keep the failing technology alive. The network repeatedly went down. Connected entities were still using modems to transfer data and the amount TWC wanted to upgrade the I-Net was out of the question.
In what would become a lasting collaboration, AISD approached the City of Austin about sharing the cost and ownership of a new fiber network. The proposal was received enthusiastically and soon two additional partners came on board. AISD, the City of Austin, Travis County, and ACC developed an interlocal agreement to construct, own, and manage a fiber network that would eventually serve schools, libraries, local government facilities, and several higher ed institutions.
The group quickly determined the school should be the entity to contract for the construction. Texas law allowed more flexibility for schools when dealing with contractors. The school was also to be the financial administrator of the GAATN organization and the member with the largest share of the network.
In 1991, the group released an RFP for construction of a new network and Southwest Bell won the contract with a bid of $18 million. Original construction, which begin in 1994, consisted of 8 rings and 2 superrings, each consisting of 114-strand fiber optic cable. After some problems, due to Southwest Bell's low quality work, construction was completed in 1998. The initial network was 345 miles long and has since expanded to 371 miles. Three points of presence (POPs) have been in place since day one of the network, including POPs to Level Three, AT&T, and CenturyLink. Approximately 30% of the fiber is currently lit and providing service to members.
The original members used a combination of bonding, loans, and money on hand to build the network. While the City of Austin has been a member since the beginning, all of its contribution is in-kind. Donating access to rights-of-way, network management, and maintenance, the city receives 12 strands wherever the network is expanded. The network is 80% aerial and 20% underground. As the network expands, the installation type varies depending on current construction, geography, and cost. Routes are often adjusted to pass city facilities to allow the city optimal use of the network. All members of the network take advantage of the 10 Gbps interconnectivity.
Wayne Wedemeyer, Director of UT Systems Office of Telecommunication Services, describes one of the biggest challenges in developing GAATN. Reaching a high level of trust between all the members and memorializing that trust into the agreement was difficult. Since each member had such specific missions and goals and all were very diverse, attaining the necessary collaborative balance took over two years. Wedemeyer also describes the arrangement with the City as a "stroke of genius." The automatic grant of five strands to the city streamlines rights-of-way negotiations.
UT provides Internet service to AISD, ACC, Travis County, the City of Austin, and LCRA. UT is able to purchase Internet service at educational rates and then sell it to the other members at cost. Wedemeyer says UT "exploded" in the ways it uses interconnectivity once GAATN was up and running. In addition to their tech incubator, UT uses GAATN's 10 Gbps to connect to its Applied Research Laboratories, dedicated to national security. Distance learning at UT and ACC have expanded significantly and AISD has plenty of bandwidth for virtual classroom activities. LRCA uses GAATN fibers to transfer wholesale power to a 50 county region.
The original $18 million investment in GAATN has been returned several times over. For AISD, the largest contributor and the entity that owns the most number of fibers, the network paid for itself in 2-3 years. In 2011, AISD saved almost $5.8 million by using GAATN instead the private market. The city of Austin saved $4.7 million, ACC saved $437,000, Travis County avoided almost $3.4 million, and the State of Texas saved $883,000. UT avoided almost $1.3 million in connectivity and LCRA saved almost $1.1 million. GAATN is a win for local and state taxpayers and for the entities it serves.
