[0] Communications (3G/4G/Wi-Fi) Performance [Fixed (Dedicated Vehicle PC)] Our vehicle PCs support a range of external antennas for 3G/4G and Wi-Fi, including high-gain roof-mounted models. These antennas are designed for performance rather than small size, and because they are located outside the vehicle they do not suffer from the reduced performance that will affect any antenna located inside the vehicle.
The performance of wireless communication methods such as 3G and Wi-Fi depends to a large extent on the antennas that are used. Not only are the antennas in mobile devices designed primarily for small size rather than performance, but they are also located inside the mobile device, which in turn is located inside the vehicle. The vehicle, of course, is mostly made of metal, a very effective blocker of electromagnetic waves.
