An open-access network (OAN) refers to a horizontally
"Open Access" refers to a specialised and focused business model, in which a network infrastructure provider limits its activities to a fixed set of value layers in order to avoid conflicts of interest. The network infrastructure provider creates an open market and a platform for internet service providers (ISPs) to add value. The Open Access provider remains neutral and independent and offers standard and transparent pricing to ISPs on its network. It never competes with the ISPs.
History
In the 20th century,
Two models
An OAN uses a different business model than traditional telecommunications networks. Regardless of whether the two- or three-layer model is used, an open-access network fundamentally means that there is an "organisational separation" of each of the layers. In other words, the network owner/operator cannot also be a retailer on that network.
Two-layer model
In the two-layer OAN model, there is a network owner and operator, and multiple retail service providers that deliver services over the network.
Three-layer model
In the three-layer OAN model the physical layer—the fiber or wireless infrastructure—is owned by one company, the operations and maintenance of the network and the provision of services is run by a second company, and the retail service providers provide the third layer.
Applications
The OAN concept is appropriate for both fiber and
In contrast to traditional municipal networks where the municipality owns the network and there is only one service provider, the open access model allows multiple service providers to compete over the same network at wholesale prices. This allows service providers to make money in the short-term, and the municipality or cooperative to recoup its costs over the long-term. The build-out and infrastructure is typically financed through low-cost bonds.
Open access networks have proven successful in parts of the United States initially as "middle mile" networks and more recently as "last mile" networks, Europe, and Asia. However, "last mile" OANs in the United States have begun to attract more interest as rural and suburban communities seek to catalyze economic development. One of the best known and most mature OANs is in Västerås, Sweden, a city of about 40,000 homes. The Västerås OAN has dozens of providers, and more than a hundred services available to users. During the past years a large number of OANs have spread all over Sweden, especially in smaller municipalities (see e.g. Säffle and Hudiksvall). In the US, open access networks like municipality owned The Wired Road[1] in Virginia have been able to attract both local and regional service providers quickly. This has resulted in the cost of Internet access and telephone service for business users in The Wired Road service area to decline by fifty to seventy percent due to the increased competition between providers. This OAN provides open access transport to any service provider that meets minimum technical and financial qualifications, including allowing existing providers to supply enhanced services, however, it does sell services itself and therefore does not compete with private sector providers.
New Zealand, Australia and Singapore also have open-access networks based on
