To the communication speed of 300 Mbps or more comparable to "WiMAX 2", HSPA's future roadmap

High-speed packet communication standard which extended the communication scheme "W-CDMA" of 3G mobile phone (3G), which is positioned as the 3.5th generation mobile phone (3.5G)HSPAMany mobile phone companies are introducing the linkage standards as "LTE (3.9 G)" and "LTE-Advanced (4 G)" as a bridging standard, and e-Mobile and Softbank Mobile are "DC-HSDPA" with downlink maximum of 42 Mbps To HSPA for data communication services, but it has become clear that HSPA is still going faster and that it will realize a communication speed of over 300 Mbps.

Details are as below.

Ericsson is engaged in base station infrastructure and so on, and occupies a large share.


We are actively developing LTE, and adopted in many countries.



And Ericsson is in a position to take leadership in the HSPA standard, successively succeeded in increasing the speed and so on. To realize high-speed communication in January this year"Multicarrier HSPA" achieves maximum downlink 168 Mbps in the world for the first timedoing.


And the road map of HSPA which Ericsson is planning to expand in the future. Next to 168 Mbps, we are aiming for 336 Mbps which is in line with the 4 th generation mobile phone "WiMAX 2 (currently maximum downlink 330 Mbps)".


According to Ericsson staff, as it is expected to be 336 Mbps, it is unknown whether the carrier will be commercialized or not depending on the balance with LTE or LTE-Advanced whether to actually introduce the carrier It was surprising, however, that 3G can be expanded to this point.
