Hot on the heels of my previous post about Japan having 600 LTE base stations, then, on Christmas Eve (2011), NTTDoCoMo in Japan launched its LTE mobile services (ie USB sticks at this stage) under the brand name Xi.
According to the press release, then the speed looks pretty crispy for those of us in the UK.
In most outdoor areas, transmission speeds are up to 37.5 Mbps for the downlink and 12.5 Mbps for the uplink, but in heavily used indoor areas, such as the terminals at Tokyo International Airport, customers can enjoy up to 75 Mbps for the downlink, approximately 10 times faster than DOCOMO’s current 3G service with HSPA.
LTE also averages about three times more data in the downlink and two to three times more in the uplink, and transmission latency is just one-fourth that of HSPA.
According to the article on Gigom, then will fall back to the carrier’s 3G network in areas that lack 4G coverage (currently, Tokyo, Nagoya and Osaka).
