Performance analysis of cellular mobile communicatons over multistar ring fiberoptic/coaxial catv networks

Abstract

AbstractThe embedded hybrid fiber‐optic/coaxial CATV network can provide cellular mobile communications with a star ring fiber‐optic network to distribute broadcasting cable TV programs and to provide the transmission of a bidirectional wireless signal. There are two lasers at the head end. The down‐link laser is split into two parts. One part is the local oscillator for the up‐link coherent detection, and the other part is externally modulated by the combined TV and wireless signals. The up‐link laser is connected to the ring network with the cascaded phase modulators scheme. For the location neighborhood and frequency reuse, we may apply the multistar ring CATV cellular network with the distance between the head end and the first‐level hub of 5 km and the distance between the first‐level hub and the second‐level hub of 0.5 km. The total hub number of 42 for the multistar ring system can support 34,860 wireless users for the IS‐54 system with frequency reuse number of 7 covering an area of radius 5 km. © 1995 John Wiley & Sons, Inc.
