I have released a first version of the field test / network monitoring application for Android 7 (Nougat) devices. With this app, you will be able to collect xARFCN data from the network and know which frequency band your smartphone is using.
I started to develop a FieldTest application for Android that I will publish on Google Play for everyone to use. I wanted to do this because of the frustration of not being able to find an app that is both eye-candy and reports useful information from my network.
Recently I discovered that Android N (7.0) provides a new method getArfcn() to get the Absolute Radio Frequency Channel Number, which gives you the exact frequency identifier that is used by the mobile phone on 2G (ARFCN), 3G (UARFCN) or 4G (EARFCN).
During a weekend in Yangon, I could test the mobile broadband, two years and a half after my last visit which was just before the new entrants, Ooredoo and Telenor, started to rollout their networks. At that time, MPT was solely dominating the market and mobile broadband was reserved for the priviledged.
Every new mobile communication generation comes with the deployment of additional radio frequency bands to support the massive growth of data volumes. With 4G LTE, there are more than 50 frequency bands standardized (if we combine LTE FDD and TD-LTE). But should we be worried at all those cell towers around us and the potential effects on our health?
