42Mb/s DC-HSPA+ expands, more being deployed

The Global mobile Suppliers Association (GSA) has published three reports depicting the growth of HSPA and HSPA+ systems. Quoting Alan Hadden, president of the GSA: "HSPA and HSPA+ technology is fast bringing Internet and broadband access to mass markets, not only in developed regions, introduction in the emerging markets is a major trend."

There are 483 operators that have committed to deploy HSPA systems in 181 countries and territories, which is more than 16 percent higher than last year. Every WCDMA operator has commercially launched HSPA on their networks, with 451 HSPA networks commercially launched in 174 countries.

HSPA+ is a mainstream mobile technology and is quickly expanding. A total of 241 operators have committed to HSPA+ network deployments, representing an increase of more than 62 percent in the past year. HSPA+ networks are being deployed in 106 countries, 39 countries more than a year ago. 187 HSPA+ systems have been commercially launched in 96 countries, confirming that more than 41 percent of HSPA operators have introduced HSPA+ on their networks.

The rapid evolution of network capabilities to 42Mb/s dual cell HSPA+ technology (DC-HSPA+) is another clear trend, as operators invest in improvements to network performance, capacity and efficiencies to maintain or enhance user experience. 62 commercial DC-HSPA+ networks have been launched while another 26 DC-HSPA+ networks are understood to be in deployment or planned. DC-HSPA+ systems combine 64QAM modulation and double the bandwidth by using dual carriers (25MHz = 10MHz). This capability was introduced by 3GPP in the Release 8 specifications, and enables a theoretical peak downlink data throughput capability of 42Mb/s.

40 UMTS900 networks have been commercially launched in 900MHz spectrum, enabling HSPA or HSPA+ operators to significantly extend mobile broadband coverage, typically as a result of re-farming some of their existing spectrum which was previously used for GSM voice service. 719 UMTS900 user devices have been commercially introduced.

GSA added 440 products to its HSPA user devices database that now includes 3,362 products. The database includes 1,413 mobile phones, which is more than 15 percent higher than a year ago. The number of routersincluding personal hotspotsincreased by almost a third in the same period.

245 HSPA+ devices (compared to 92 a year ago) are launched. 137 devices support 21Mb/s peak downlink speed, 14 support 28.8Mb/s, 93 support 42Mb/s DC-HSPA+ (compared to 22 a year ago), and one device supports 84Mb/s. 27 HSPA+ smartphones (including carrier and frequency variants) are confirmed, including four phones that support 42Mb/s DC-HSPA+. The number of HSPA-enabled tablets increased from 13 to 43 since last year, reflecting a growing interest in this expanding device segment.
