Satellite Phones - The Toughest Handsets

Businessman using phone in desertA satellite phone needs to be relied upon by those traveling in some of the toughest places on earth. Often it will be the only source of communication so it is understandable that 100% reliability is required. In this post we take a look at the durability of the toughest satellite phones.

What makes a satellite phone reliable?

Call quality, network coverage and availability are all important but another requirement is robust design and build of the satellite phone itself. This robustness is measured by the IP Rating.

What is an IP Rating?

An IP Rating scores how protected the satellite phone is from dirt and moisture.

It is composed of two characters, the first symbolises protection from dust and dirt and the second from water. The higher the numbers, the better the protection.
