Title:Capacity
of the WCDMA-FDD Mobile Internet in High-Mobility Environment
Abstract: The main objective for the 3G systems
has been high-bit-rate services for mobile users. Basically the 3G systems
should be able to offer at least 144kbps (preferably 384kbps) for high-mobility
users with wide-area coverage and 2Mbps for low-mobility users with local
coverage. However, in a high-mobility environment, the capacity significantly
reduces. The scope of this paper is to outline how to calculate the capacity
of the WCDMA FDD radio access network. Specifically, the paper analyzes the
capacity of WCDMA-FDD uplink and downlink for mobile Internet networks in
the high-mobility environment. The methods described in this paper can be
used for rough estimates suitable in the dimensioning process and offers
a quick analysis for mobile cellular engineers.
