Getting in touch with mobile-broadband providers from Denmark

Below there are there major mobile-broadband suppliers in Denmark. By clicking on their name you will be directed to their homepage. Near each provider there is also a contact method. Each of these providers has been contact in order to find out their bulk pricing and special offerings for a project like this.

Networking for components

Having the prototype components clearly listed, helped us get the big picture in our minds again. It also helped identifying the following:

  • what more to get
  • suppliers to contact
  • people to talk to
  • alternatives



We called it “Networking for components” or “Networking and suppliers”.

Prototype overview

Facts can get confusing when you are handling a big project over a relatively big period of time. The way solved this problem was by doing a graphical overview of what we have and what we want to have, using paper and post-its.




Core elements

  • the cushion
  • electric pump
  • electric valve
  • microcontroler

Networking Add-on 1

  • 3G/4G adapter
  • Web-server
  • Web interface

Networking Add-on 2

  • Bluetooth dongle
  • Smartphone
  • Smartphone application

Networking concept 2

The following depicts and describes the 2nd networking concept.

The system



  • the wheelchair user will sit on the optimized cushion, which is placed on the smart wheelchair in the back of the smart wheelchair a embedded deviced will be attached
  • connected to the embedded device there is a bluetooth usb adapter
  • the bluetooth usb adapter will comunicate wireless via the 2.4 Ghz signal and it will send the necesarry information to the smartphone
  • a PromComfort employee will manage the data just by passing by the wheelchair and initializing a wireless connection with his smartphone

The user interface

The fastest and most efficient way we can deliver a user interface is by creating an Android app. The app must enable the user to do the following:

  • check current pressure value
  • adjust current pressure
  • set a minimum pressure value

The interface should be straight-forward an minimalist, emphasizing on functionality rather than design. Bellow, there are 2 print-screens of the current Android app mockup.
