What are the challenges for the Wi-Fi in moving vehicles (car, Bus/shuttle)? What are the parameters to calculate the possible drop in signal receiving? Will any packets get dropped when moving fast? How the Doppler Effect works here?

Simultaneous user limitations. Generic systems are designed to sustain five or 10 users at once, when a commercial bus may carry 60 people or more. A single rider may connect three devices, thus utilizing most available channels.
    Power failures. If a system isn’t designed for moving vehicles, it will likely suffer frequent power spikes, which tend to require system resetting. Beyond the hassle of constantly finagling with too-basic Wi-Fi equipment is the fact that, for union or policy reasons, many bus drivers are not allowed to touch electric components.
    Poor Antenna Connections. Typically, mobile Wi-Fi systems see the best performance with roof-mounted antennas. However, most low-end mobile Wi-Fi systems do not accommodate roof mounting, and those that do, require a tricky USB card connection that tends to disconnect frequently.
    Limited Carrier Accessibility. Lower-end Wi-Fi configurations are single-carrier, single-SIM-card systems. Crossing a country line or moving into a certain carrier’s dead zone could interrupt access.
    No Fleet-wide Software. Without a single system overseeing performance, it’s very difficult to implement effective Wi-Fi access. Centralized software is a must-have for managers overseeing dozens of vehicles simultaneously. Basic systems can’t provide a bird’s eye view of Wi-Fi operation.
