KDDI doubles the capacity of base stations and avoids communication speed degradation in busy streets

With the rapid spread of smartphones and the like, traffic volume has been increasing recently, especially the communication speed in the downtown area which is being influenced.

In densely populated areas, the number of people covered by one base station increases and the communication speed tends to drop by all means, but KDDI is a policy to avoid lowering the communication speed by doubling the capacity of the base station Was revealed.

KDDI, base station capacity doubled Expanded smaho expansion, line puncture aiming aim (1/2 page) - Sankei Biz (Sankei Biz)


According to Sankei Biz reported, KDDI will raise the communication capacity of mobile phones up to twice in April 2012 to respond to the rapid expansion of data traffic volume due to increased sales of smartphones.

This is to improve the function of the base station for the 3rd generation mobile phone (3G) currently, and to level the data reception at multiple base stations to prevent a significant decrease in communication speed, etc. To raise, we introduced a technology called "EV - DO Advanced".

"EV-DO Advanced" is "to make it possible to use another base station where radio waves are reachable when communication is crowded and no speed" "One base station covers according to network congestion Although it is a technology to realize efficient communication by taking measures such as "to change the area", it is said that it is possible to efficiently process 1.5 times to twice the present capacity with the same base station equipment I will.

The control image of "EV-DO Advanced" posted in the monthly issue "Monthly Telecommunications" special issue magazine for business leaders in the telecommunications industry is like this. It will be able to access relatively base stations rather than crowded base stations.


This prevents the phenomenon that communication is not connected in downtown areas where smartphone users concentrate, and it is said that the communication speed will not be greatly reduced, and the improvement of the base station is expected to be about 7, out of the 53,000 outdoor base stations, next year We will change all the software of all facilities except for the base station that stops in the month.

In addition to KDDI's existing 3G line, we launched "htc EVO WiMAX ISW 11HT" smartphone that supports both "downlink maximum 40 Mbps downlink and up to 10 Mbps uplink mobile WiMAX deployed by subsidiary UQ Communications," seamless switching Available and free of chargeThe largest public wireless LAN service in Japan "au Wi-Fi SPOT"In order to prevent the puncture of the line due to the increase in traffic volume, such as deployment, we are not only restructuring the base stations but also various measures are launched.

As for the inquiries about this news report to the KDDI Public Relations Division, it is true that the introduction of "EV - DO Advanced" is a fact, the introduction time will be around April 2012 and the base stations will be arranged so that the coverage areas will overlap Although it is a story in populated areas,The number of base stations present now becomes 1.5 to 2 times the number of base stationsAnswer.

If there are base stations AB adjacent to the area, if 100 users exceeding the accommodation limit are connected to base station A and 50 users who are below the accommodation limit are connected to base station B, "EV-DO Advanced" If it is a corresponding base station, it is possible to efficiently use the base station because it is possible to distribute the user of the base station A exceeding the capacity to B to B.
