What is EVDO MC by KDDI definition?EVDO MC is a subset of EVDO Rev.B.EVDO MC supports bundling up to three (3) DOrA carriers, compared with EVDO Rev.B bundling up to 15 DOrA carriers.EVDO MC does not support 64QAM that composes EVDO Rev.BConsequently, EVDO MC can be implemented solely by the software upgrade of radio access network equipment.

Why Is KDDI Going to Upgrade DOrA to EVDO MC?

KDDI’s Plan for LTE (1) : Overlay Deployment Across Freqs.

12

At KDDI, 20MHz (10MHz x 2) is available at 850MHz band and at 1,500MHz band each for the LTE deployment.850MHz spectrum is the digital dividend of TV broadcasting as well as the fruit of the painful clean-up process of its own 800MHz spectrum being used for 3G CDMA operations. The clearing process will complete in July 2011.1,500MHz spectrum is unique to the Japan market and the dividend of the 2G TDMA cellular operations.

KDDI’s Plan for LTE (2): 1xCSFB

13

KDDI positions LTE as a means of efficiently accommodate the data traffic within the cellular mobile services offering and will continue to use the existing CDMA2000 1x for voice traffic.KDDI has been actively working in both 3GPP and 3GPP2 to complete the specifications for the circuit-mode fall back to 1x for incoming voice calls during a data session over LTE.

Limit in spectrum availabilityThis is the challenging issue regardless of CDMA, UMTS, LTE or WiMAX under the circumstance of bandwidth hungry Internet era. How can we add new spectra for 3G and beyond, and how can we refarm existing spectra used by 2G and 3G?

Globally common spectra for LTE deployment unlikelyIn 3GPP, many band classes have been defined: 700MHz, 800MHz, 900MHz, 1.5GHz, 1.7GHz, 1.8GHz, 2.1GHz and 2.6GHz. This leads to the advantage of existing 3G networks including CDMA and EV-DO, for which most of deployment are globally at 850MHz and 2.1GHz.

Infrastructure costThe customer perception for the broadband access service is the “All-You-Can-Eat” flat rate. How can MNOs manage the ROI in bandwidth without the expectation of increase in ARPU? – Can the single standard and well-defined interface specification between nodes, leading to the real multi-vendor procurement environment, be the answer?

Backhaul availability and costThis is another issue relevant to the infrastructure deployment. As the bandwidth of radio link evolves larger, the bandwidth requirements for the backhaul grow as well. The availability and cost of the backhaul will be a bottle neck of network deployment.

IPv4 Address SpaceThe public IPv4 address has become a scarce resource. The emerging deployment of networks could be designed to use IPv6 addressing for its own internal purpose, but this could cause a limitation in the access to the Internet running on the public IPv4 addresses on which many of services nodes rely.
