GPRS is weak with Introduction to 3G Mobile Communications 6 OVERVIEW respect to real-time services It can be seen that HSCSD will be only a temporary solution for mobile data transmission needs It will only be used in those networks where there is already a high demand for quick data transfer and something is needed to ease the situation and keep the customers happy while waiting for 3G to arrive The... was Introduction to 3G Mobile Communications 14 OVERVIEW disbanded, and in January 2002 a new organization, 3G Americas, was founded The mission of 3G Americas is to support the migration of GSM and TDMA networks into WCDMA systems in the Americas IMT-TC is further divided into two standards: TDD and TD-SCDMA Both standards are specified, but so far there has not been much commercial interest toward...

WCDMA as their 3G radio interface candidate Moreover, the largest Japanese mobile telecommunications operator, NTT DoCoMo, issued a tender for a WCDMA prototype trial system to the biggest mobile telecommunications manufacturers This forced many manufacturers to make a strategic decision, which meant increasing their WCDMA research activities or at least staying out of the Japanese 3G market Later... entry-level introduction to 3G, with an emphasis on the 3GPP-specified frequency division duplex (FDD) mode system, which will most probably be the most widely used 3G system It is not the intention of this book to go into great detail 3G is a broad subject, and it would be impossible to provide a detailed analysis of every aspect in one volume Instead, the basics are discussed and references to other... spectrum to FDD systems, and the asymmetric part to TDD systems The proposed spectrum allocations for UTRAN TDD are 1,900–1,920 MHz and 2,010–2,025 MHz The first granted 3G Introduction to 3G Mobile Communications 16 OVERVIEW TDD licences have been 5 MHz per operator, so each TDD operator could only have one TDD carrier Second, many services provided by the 3G networks will require asymmetric data transfer .
