Mobile Marketing Data Laboratory recently conducted a study into data packet congestion in LTE 4G networks in Tokyo. Packet congestion was defined in this survey as when on an LTE connection the web page under test – Yahoo! Japan’s top page was used – fails to completely load within 30 seconds.
Between the 10th and 14th of June 2013 the investigation team visited the six busiest stations on the Tokyo Yamanote line, choosing two spots on each to test, during both the morning peak period of 7 am to 9 am, and evening peak of 5 pm to 7 pm. 100 connections were made from each collection point, for a total of 1,200 tests for each phone.
Specifically, the stations and locations were Shinjuku South and East entrances, Ikebukuro in front of South ticket wicket and Seibu East entrance, Shibuya in front of Tamagawa ticket wicket and Hikarie entrance, Tokyo Yaesu Central entrance and Marunouchi North entrance, Shinagawa Minato South entrance and Central ticket wicket, and Shinbashi Kasumori entrance and SL Plaza.
