We see from your search that you're looking for information on the term "WCDMA",
and we have a large number of manufacturers' news releases and technical articles here on Electronicstalk which will be of interest.
Let me be your guide.
Start with
the news release Location test system adds new options from
Spirent Communications, which we summarised at the time by saying "Spirent Communications has added two important new capabilities to its market-leading UMTS Location Test Solution".
A couple of weeks before,
we featured the news release GPS tests simulate real-life conditions from
Cetecom: "The standards require test scenarios with six to eight simultaneous satellites, but Spirent ULTS is equipped with up to 12 satellite channels".
In January 2008, we covered the news from setcom
concerning its S-CAT 6000
- take a look at R and D tester offers wide compatability
which says: "The S-CAT 6000 seamlessly integrates with a wide range of external equipment, enabling testing over RF bearers such as GSM/GPRS, EGPRS, WCDMA, UMA/GAN, CDMA 2000, LTE and TD-SCDMA".
Take a look also at the news release from picoChip Designs, Reference design supports low-cost basestations,
as well as Acquisition enhances RF expertise from Spreadtrum Communications,
and Brick drops in to boost basestation efficiency from Ericsson Power Modules.
