DoCoMo's Auto GPS and Twitter are linked to each other to display 'Hibiki' in real time

Docomo can periodically locate the location information of the user in the background and automatically distribute the information at that locationAuto GPSWhile providing the service, we will demonstrate the service that real-time detection of "active place" attracting a lot of people's attention by linking the auto GPS and TwitterWireless Japan 2014We are doing at the docomo booth.

Arrived at the DoCoMo booth.


◆Geographical Time Line
A sign with an unfamiliar name "Geographical Time Line (GT)" is put on it.


GT is a service that displays real-time active place where many people are on map on cooperation of auto GPS and Twitter.


The Twitter timeline is displayed on the right side of the map. The place is detected from the character information written in this tweet, and the information is displayed on the map with the Twitter icon of the bird mark on the screen ......


The place with many people with auto GPS information is distributed as a light blue dot on the map, which is represented by a slightly small dot. When many people gathered from the information of Twitter and AUTO GPS and it was judged as "active place", it changed to an orange arrow icon (AGAIGE mark). It is clear that the "place where it is exciting" in real time is obvious.


By analyzing a combination of key phrases of a specific tweet, various information can be displayed on the map. For example, analyze tweets about "cherry blossoms" to analyze "cherry blossom front" and information such as "rainy season" from tweet about "rain" can be analyzed in real time.


◆Next Generation Mobile Communication System (5G)
Besides GT, at the docomo booth, explanation on the next generation high speed wireless communication standard 5 G technology was done.


The current LTE is a technology that should be said to be 3.9 G accurately, but it is a "true 4 G" standard in 2015LTE-AdvancedThe service starts, radio communication finally arrives at 1 Gbps downstream. Ultra high-speed mobile communication of 10 Gbps will be realized until 5 G beyond that.


In DoCoMo, a technology called C / U separation architecture (phantom cell) that uses "macrocell" which uses relatively low frequency band such as 800 MHz and "small cell" which uses high frequency band exceeding 10 GHz in a wide band We are planning to realize 5G by using it.


◆Voice over LTE (VoLTE)
While the transition to LTE is ongoing, DoCoMoVoLTE (Borte)Commentary on the features of the booth.


Appeal clear sound quality and low voice delay.


In the comparative demonstration that compares and listens to VoLTE and FOMA voice calls that were being held, it was confirmed that VoLTE is definitely clearer sound quality.


It is around 2020 that 5G super high speed communication starts. At the Tokyo Olympic Games, I am looking forward to what kind of new content is born utilizing super high speed communication.
