Wireless networks work by means of “Radio Waves” rather than cables to transmit data between PC's. In-building solutions are increasingly deployed and introduced to mobile networks, as user demands for “everywhere coverage” are matched by the opportunity for mobile operators to offer improved services and increase traffic revenues. (Weiss 2008) Site owners more frequently appreciate and recognize the value of IBS, that most often enhances the general perception and value of the property, and provide a tailor-made infrastructure that may both attract as well as retain key tenants.
Wireless technology can provide many benefits to computing including faster response to queries, reduced time spent on paperwork, increased online time for users, just-in-time and real time control, tighter communications between clients and hosts. Wireless Computing is governed by two general forces: Technology, which provides a set of basic building blocks and User Applications, which determine a set of operations that must be carried out efficiently on demand. (Mehta 2007)This paper summarizes technological changes that are underway and describes their impact on wireless computing development and implementation. It also describes the applications that influence the development and implementation of wireless computing and shows what current systems offer.
Equipments
The main equipments for the wireless networks in buildings are consist typically of a micro or a macro base station that is connected to a number of distributed antennas via coaxial cables and combining equipment such as power splitters, power tappers, combiners, multi casting matrixes etc. (Couzins 2008)The DASs can support one or several mobile operators and one or several mobile technologies (GSM, WCDMA, CDMA2000, TETRA etc).
Discussion
Wireless Optical Networking (WON) is a carrier-grade 'last mile' technology based on a network of interconnected free-space optical communication links. The network provides multiple routes to each building, rerouting around network faults and interconnectivity to other communications networks(Rothman 2008).
Wireless optical networking is an innovative technology that improves upon the relatively new concept of free-space optics. Traditional free-space optics is based on wireless laser communications between two optical transceivers aligned to each other with a clear line of site(Weiss 2008). Typically, the optical transceivers are mounted on building rooftops. The optical transceiver consists of a laser transmitter and a detector to provide full duplex capability. Free-space optics enables fast deployment of broadband access services to buildings; the time-consuming and expensive process of getting permits and trenching city roads is ...
