This post aims to iterate the different resources that may be needed while enabling Wi-Fi for moving vehicles with many concurrent users. Like any Wi-Fi network, the resources are pretty much the same:
- reliable hardware (routers),
- a network controller (software to mange to your Wi-Fi network),
- and an reliable mobile Internet bandwidth (4G LTE SIM cards for Bulk Usage).
However, having seamless Wi-Fi in a bus, train, ship or ferry has more complication involved as DSL/cable cannot be available in a moving vehicle. This makes it difficult to :
- to maintain connectivity throughout the journey
- and get sufficient bandwidth to support multiple users.
- to manage SIM cards across multiple vehicles
This is the reason enabling passenger Wi-Fi services for vehicles in motion use 4g LTE SIM cards with routers. Such SIM cards can be used in routers that follow IEEE 802.11p standards – a special wireless system specifically meant for wireless access in vehicular environments (WAVE).
Some off-the shelf WiFi routers are equipped with a USB port that allows you to directly plug-in a 3G modem dongle. These routers offer a cheap way to experiment with WiFi on-the-move. However, they cannot be relied upon for anything more than family cars with 1-2 Internet users.
New technologies like RR850 routers and RebelRocket SIM cards now make it possible to deliver Internet on-the-go and enable WiFi for buses, trains, ferries and planes. These effortless plug n’ play routers come with cigarette car lighter chargers and pre installed SIM cards that work across European and Scandinavian countries.
One of most notable feature about these SIM cards is that it is specially designed for on-board passenger Wi-Fi usage. It uses a special technology that automatically restricts adult content, HQ videos and torrents. The service is particularly useful for transportation companies as it reduces data consumption and therefore delivers a seamless Wi-Fi experience even if there are many concurrent users on board.
