W-CDMA Test

The expansion and upgrading of W-CDMA networks worldwide to support HSDPA and HSUPA (collectively HSPA) is a substantial investment by the network operators. Handset design and development needs to keep pace to ensure end-user customers upgrade their phones and buy and use the new network services that they support.

Keysight products help speed your time to market and to a return on your product development investment–whether you design components and subsystems, manufacture handsets or base station equipment, or manage the expansion or upgrading of a complete network. Accelerate Wireless Design and Test with Flexible, High-Performance Platforms
