Orkney is correct.
The network is simply a large ongoing cost to us that we have to pass back to our customers.
You have to remember, behind the network are multiple servers handling the load of 400+ RadarBox sending data, sorting the data and then sending back out again. Not only does that mean we need fast servers able to cope with the load we also need to have the bandwidth.
An example to show how much data is being sent out. On average 300 users connected at one time downloading 200kb of data every minute. That means the server needs to send out 60mb per minute, 3.6 GB per Hour, 86 GB per day, which is nearly 3TB a month of bandwidth which is required. We won't provide a breakdown of costs but I am sure you understand this is not cheap and something we canot absorb ourselves.
