This paper describes the design, implementation and management of an integrated partial physical infrastructure of a wireless local and wide area (WLAN, WWAN) networking system. The system objectives are to serve and support the existing networking and data communications services of Palestine Polytechnic University PPU, and to facilitate connectivity of buildings within university campuses. The system consists of two main components: the first one represents a WLAN that is based on the communication protocol 802.11b, whiles the second represents the WWAN that connects two main buildings using two access points and radio frequency transmission technology. As a measure of performance, preliminary results showed that the system maintains an acceptable and secure data transfer rate between the sending and receiving sites. The speed of data while connection is maintained varies in the range of 2 to 10 Mbps and 10 to 50 Mbps for an indoor WLAN and an outdoor WWAN respectively. These findings are a good evidence of the efficiency of the integrated communication system with low operational cost and with feasible practical implementation.
