This application note provides practical information to help users understand PN code generation and complex scrambling, which are required in the WCDMA standards. Typically, these operations are performed on Architecture-Specific Integrated Circuits (ASICs), but here we explore the use of the Motorola StarCore SC140 digital signal processing (DSP) core to accomplish the same task.
PT Indosat Tbk. (Indosat) has awarded Ericsson a contract extension to expand its WCDMA/HSPA network coverage in greater Jakarta, Indonesia. Indosat consumers in the area will receive wider coverage and faster mobile broadband speeds. Ericsson will be responsible for supplying core, radio access network and transmission equipment, covering network design, deployment, integration, performance and improvement of their WCDMA/HSPA network. The network coverage expansion would bring Indosat service to more of its greater Jakarta subscribers.Indonesia News Blog: http://indosnesos.blogspot.com
As per Wireless Intelligence, WCDMA HSPA cellular connections are expected to reach 40 million worldwide by end of 2008. By 2010, WCDMA HSPA is expected to represent around 45% of total WCDMA cellular connections, which are also on track to exceed GSM connections by 2010 in those countries where the network has been launched.Asia-Pacific is driving growth during the initial phase of adoption, while European operators will boost total WCDMA HSPA cellular connections from the end of 2008. WCDMA HSPA is expected to increase data traffic and non-voice revenues.WCDMA HSPA will be commercially present in more than 60 countries by the end of next year, based on announced plans. With the aim of bringing broadband speeds to mobile networks, WCDMA HSPA is a software upgrade to existing WCDMA networ
NOKIA PRESS RELEASE April 12, 2007Nokia has paid less than 3 per cent gross royalty rate for WCDMA handsetsNokia today confirmed that until 2007 it has paid less than 3 per cent aggregate license fees on WCDMA handset sales under all its patent license agreements. This number represents Nokia's aggregate gross royalty payments made under all the numerous patent license agreements applicable to its WCDMA handsets. It excludes infrastructure related royalties and all royalty income collected by Nokia.The above WCDMA handset related royalty payments made by Nokia include all WCDMA handset royalty payments made to Qualcomm.From April 9, 2007, Nokia contractually has a fully paid up license covering Qualcomm's early patents and thus those patents are licensed to Nokia royalty free for its handsets going forward in perpetuity. Therefore Nokia's licensing agreements with Qualcomm for the future will focus only on the terms for Qualcomm's newer patents.About NokiaNokia is a world leader i
Book Description
3rd generation radio systems will be increasingly developed, deployed and operated in the years to come. TDD is one of two main approaches to implementing these 3G systems, so that there will be an increasing need for the engineering community to learn quickly and comprehensively about the TDD technology. As 3G systems become popular, the topics will no doubt be introduced to
