There is a very strong business case and momentum for deploying UMTS900 (WCDMA-HSPA) systems in the 900 MHz band to help operators efficiently extend voice, data and mobile broadband services coverage by leveraging the advantages of lower frequencies.
This GSA paper highlights the benefits and opportunities when deploying UMTS900, typically as a complement to 2100 MHz 3G/UMTS systems, and reports on global network deployments, launches, trials, regulation, and the UMTS900 eco-system i.e. availability of user devices.
