なぜ信頼区間がモバイル・ネットワーク・エクスペリエンスの分析に不可欠か

Posted: Feb 13, 2019

科学実験の世界には、精密測定というものはありません。むしろ、標準的な科学的アプローチでは信頼度を扱います。信頼度が高いものを高い精度で言明できるわけですが、いくら精密に測定しても絶対数で表せるところまで達することは決してありません。科学者はこの精度を「信頼区間」と呼ばれるもので表現します。世界中のあらゆる業界や領域で採用されている規格です。日常生活で信頼区間の最も良く知られている例が、よく世論調査で開示される 誤差の範囲 です。

Movistar and Vodafone tied in our Spain 4G peak speed analysis

Posted: Dec 06, 2018

When it comes to mobile network speeds in Spain, it was something of a two-horse race in our last State of Mobile Networks report. Movistar won our 3G download speed award, Vodafone took both overall speed and 4G upload — but the two drew for our coveted 4G download speed prize. So we drilled down a bit deeper into our 4G download data by looking at their peak speeds, where we discovered another tie between these fierce Iberian rivals.

With new models, Apple will raise mobile network speeds

Historically, Apple has focused on the speed of its application processor or graphics; we believe it’s now time for Apple to talk about mobile network speeds as well.
