Scalable UMTS
Solution for Refarming Fragmented GSM Spectrum
Operators across the globe are rapidly refarming their valuable 900 MHz spectrum and deploying UMTS/HSPA+. UMTS900 has already become mainstream with ~60 commercial networks and ~1000 devices available in the market today. However, one major challenge that many operators still face is that their GSM 900 spectrum is often less than 5 MHz or in non 5 MHz multiples, creating unusable narrow-bandwidth fragments. Also, in many cases it may not be feasible to clear spectrum for a full UMTS carrier. S-UMTS effectively addresses these challenges by allowing UMTS/HSPA+ in smaller than 5MHz bandwidths. Additionally, this also allows operators to increase the utilization of their existing UMTS spectrum.
S-UMTS is a candidate feature in 3GPP Rel 12, and is supported by many industry leaders. Qualcomm is showing a live over-the-air demonstration of S-UMTS at Mobile World Congress 2013.
UMTS/HSPA+ in ½ and ¼ bandwidths
UMTS/HSPA+ in ½ and ¼ bandwidths
S-UMTS enables UMTS/HSPA+ in ½ and ¼ bandwidths of standard UMTS allocations, and supports both WCDMA/+ voice/SMS and HSPA+ data services. It incorporates a simple system design that scales the overhead with the amount of bandwidth. S-UMTS is applicable to all the 3GPP spectrum bands.
Maintains Coverage, Spectral Efficiency and Voice Quality
Maintains Coverage, Spectral Efficiency and Voice Quality
S-UMTS maintains the coverage and spectral efficiency of UMTS/HSPA+, thanks to the overhead that scales with the bandwidth. Also, for the same reason, the overall cell capacity scales with the bandwidth. As S-UMTS uses the same vocoders, it also offers the same voice quality. The simple system design results in less complexity in the implementation of S-UMTS in devices.
Enables Refarming of All GSM Spectrum

S-UMTS enables smooth refarming of all the GSM spectrum, by allowing phased migration to UMTS/HSPA+. HSPA+ Multicarrier ensures that all the fragments, be it isolated or remainder in excess of 5 MHz, are utilized either by combining them together or with full UMTS/HSPA+ carriers in 900MHz/2.1GHz bands.
