How does public transport WiFi work?

In this day and age, you may take it for granted that when you jump on a bus or a train you will automatically be able to access free Wi-Fi. Have you ever wondered “How does public transport Wi-Fi work?”
Connection to the internet, whilst travelling by public transport, has become crucial in today’s living.

What are some issues with public transport Wi-Fi?

Internet and Wi-Fi connections are vital for businesses; a high quality, smooth connection is required for critical communications, logistics, vehicle management and social media.

  • Remote Locations
  • Slow Internet speeds
  • No Coverage

The greatest challenges experienced with global Wi-Fi connectivity:

  • Download and upload speeds
  • 3G & 4G, and now 5G connectivity
  • VHF & UHF communications for data management of the vehicle
  • GPS facilities for vehicle management

The heart of any system is the antenna, our nowadays more than one antenna; You could throw caution to the wind and spend £’s on an all singing, all dancing vehicle system, however, if you don’t invest in good antennas your system will not be able to perform to the best of its ability.

Many attempts have been made with different types of antennas. These range from simple single band whip antenna through to multiband designs in a single moulding.

In addition, poor build quality, poor IP rating and vibration from the vehicles, lead to these devices being in constant repair and in the end, having to be replaced.

Why do our vehicles need more than one bandwidth?

Poor design of multiband antennas can lead to interference between the required bands.

To give you an example; a bus could require various bands for different functions:

  • VHF or UHF for voice communications through a two-way radio system
  • GPS for vehicle telematics
  • LTE 3G/4G/5G for data transfer, more are moving to cellular.

When housed incorrectly, in a multiband encasing, these antennas could potentially interfere with each other. This gives way to issues such as:

  • Loss of signal
  • Inability for bands to function in tandem
  • Poor quality transmission

With all of these issues in mind Antenna & Cables, have developed solutions for both train and bus; versatile low profile train, bus and coach antennas designed for use in challenging environments.

All solutions offer MiMo Multi Band antennas, suitable for VHF, UHF, WIFI, LTE 3G/4G/5G GSM & GPS/GNSS.

What testing is done to make sure the antenna work at their optimum capability?

Extensive development has been carried out during the research and development phase:

  • Vibration testing
  • Efficiency – VSWR
  • EMS and radiation testing

VHF, UHF, WIFI, 3G/4G/5G GSM & GPS can be housed in the same casing for a functional, reliable all band antennas – the antenna below are an example of ‘same casing, all band’ antenna
