News, insights and technical articles on GSM signal boosting, ASTRID and in-building coverage.

Why poor mobile reception affects your body, your battery and your mood all at once. Everyone knows the picture: your phone is lying next to you on the table, one bar, and yet everything seems to work fine. WhatsApp comes in, a call goes through, the mail refreshes. It works, right?
