An Internet content delivery network deploys one or more CDN server regions in an enterprise and manages those regions as part of the Internet CDN. In one aspect of the invention, a CDN service provider (CDNSP) deploys one or more CDN regions behind an enterprise's corporate firewall(s). The regions are used to deliver Internet content—content that has been tagged or otherwise made available for delivery over the Internet from the CDN's content servers. This content includes, for example, content that given content providers have identified is to be delivered by the CDN. In addition, the enterprise may tag intranet content, which is then also served from the CDN regions behind the firewall. Intranet content remains secure by virtue of using the enterprise's existing security infrastructure. In accordance with another aspect of the invention, the CDNSP implements access controls and deploys one or more CDN regions outside an enterprise's firewall(s) such that intranet content can be served from regions located outside the firewall(s). In this embodiment, the CDNSP can provide granular control, such as permissions per groups of users. In this way, the CDNSP, in effect, extends a conventional virtual private network (VPN) to all or a portion of the ICDN, thereby enabling the CDNSP to use multiple regions and potentially thousands of content servers available to serve the enterprise's internal content. In addition to making internal content available from the edge of the network, the CDNSP provides a mechanism by which an enterprise may share secure data with its business partner(s) without setting up any special infrastructure.

A decentralized asynchronous wireless communication system is disclosed for providing voice and data communication that allows flexibility of communication paths for local communication or for communication to external networks. The system makes use of communication docking bays that may communicate in a local mode with other communication docking bays or handsets within a same microcell via signal extenders. In an extended mode, a communication docking bay located in a first microcell of a first macrocell may communicate with a second communication docking bay or handset in a second microcell of the first macrocell via signal extenders and a network extender. In a remote mode, a communication docking bay located in a first microcell of a first macrocell may communicate with a second communication docking bay or handset in a second microcell of a second macrocell via signal extenders and network extenders.

The invention provides solutions, including devices, systems, methods and software, for allowing interoperability between legacy stations and extended-range stations in a wireless network. Merely by way of example, an access point might be configured to transmit communications (such as beacon frames, broadcast frames, multi-cast frames, etc.) in a first mode and/or a second mode. The first mode might not employ extended-range technology, such that communications transmitted in the first mode can be received and/or interpreted by legacy stations, while the second mode might employ extended-range technology, such that communications transmitted in the second mode can be received by extended-range stations outside the range of basic-range communications. As another example, the access point might be configured to establish transmission “windows,” such that legacy stations are free to transmit during a first time period, in which extended-range stations are prohibited from transmission, followed by a second time period, in which extended-range stations are free to transmit, while transmission from legacy stations is prohibited.
