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.
