A system comprising: a local area network (LAN) device configured to produce a local area network (LAN) signal; and a modem unit configured to produce, based on the local area network (LAN) signal produced by the local area network (LAN) device, a transport modulated format signal suitable for transmission over transport cabling. The modem unit further configured to provide power to the local area network (LAN) device.

Architecture for signal and power distribution in wireless data network

An architecture is provided for coupling wireless local area network (WLAN) signals between an internetworking device and a remotely located access point using a transport network. The access point is coupled to the transport network for communicating with the internetworking device. The access point includes a wireless local area network (WLAN) access point and an access point remote converter. The WLAN access point receives wireless local area network signals from wireless computing equipment and converts such signals to local area network compatible signals. The access point remote converter receives the local area network compatible signals from the WLAN access point and converts the signals to transport modulated format signals suitable for transmission over the transport network.

A simple and low cost architecture for a distribution network is provided for coupling wireless local area network ('wireless LAN') signals between geographically distributed access points and centrally located internetworking devices. The distribution network eliminates complexities involved with the deployment of such systems in the past, which have typically required the computer network-compatible wiring to be extended to each access point directly from an internetworking device such as a repeater, bridge, router, or gateway. The distribution network makes it economically efficient to deploy wireless local area networking equipment in locations where wired network infrastructure is not readily available. In particular, any convenient existing physical wiring, such as may be provided by the existing optical transport cabling of a fiber optic network, is used as a physical layer transport medium to carry the wireless local area network signals between the access points and centrally located network hub equipment.

Architecture for signal distribution in wireless data network

A distribution network for coupling wireless signals between an internetworking device and a plurality of remotely located access points to provide wireless service within a geographic coverage area composed of microcells. The distribution network makes use of available transport cabling. Examples of such wireless signals include wireless metropolitan area network signals and mobile broadband wireless network signals.

Architecture for signal distribution in wireless data networks

A system in accordance With the principles of the present invention employs a loop field test to predict the data rate capability of at least one loop other than the one tested. A local telephone loop is selected for field testing that includes wideband noise testing and signal frequency testing. This reference loop is characterized in response to the results of the field tests and the characterization is used to predict the data handling capability of other similar loops. In an illustrative embodiment one loop Within each binder group terminated at a telephone office is selected as a reference loop and the data rate capability of the other loops Within the binder group are predicted, based on the characterization of the reference loop.

Apparatus and method for communications loop characterization

A simple and low cost architecture for coupling wireless local area network signals between geographically distributed access points and centrally located internetworking devices. A cable access point (CAP) is associated with each respective microcell. Each CAP includes a remote bridge to convert such signals to a convenient transport format depending upon the available cabling. For example, if the available cabling is a cable television (CATV) plant, the transport signals are first converted to a T1 format and up-converted to a carrier frequency suitable for the CATV plant. Alternatively, the transport signals may be converted to IEEE 802.3 cable modem signals. If the available cabling is twisted pair telephone type wiring, the remote bridge converts the transport signals to a suitable Digital Subscriber Line (xDSL) format. The transport signals are collected at a central distribution or head end access point (HAP). At this location, a remote bridge then converts the signals from the up-converted T1 format or the xDSL format, back to the Ethernet local area network format. These Ethernet signals are then suitable for coupling to a local area network hub or other internetworking equipment such as repeaters, bridges, routers, and gateways.

A wireless telephony system is described wherein remotely distributed transceivers, each of which has only a single antenna for receiving signals from wireless telephones, and such remote transceivers are located close enough so adjacent transceivers receive signals from the same wireless telephones to provide reverse link antenna diversity to help prevent loss of signal from a wireless telephone.
