Manage Wireless Hotspot users!
If you connect to a wireless Hotspot and buy time, let's say one hour, then as soon as you connect for the first time and enter your password, the clock starts. If you spend 5 minutes online, with UM, the clock is still running. After one hour, your "one hour" of purchased time is finished. With Radius manager you still have 55 minutes left. That is the first problem.
If you buy one day, or in other words, 24 hours, you do not always get 24 hours because if you buy your "24 hours" at 23:55, you only get 5 minutes, because Radius manager checks at midnight, and disconnects you as you are now in the next day.
Both these two types of time period billing (online time and time period) are not possible for Hotspot.
Radius Manager is a good software system for customers who pay for a long term service, who pay for fixed term contracts (perhaps 30 days or more) as if they were fixed connections. But for Hotspot users, who visit a cafe for maybe just one hour, or a local area with our hotspot for a few hours, these two business models for time accounting are impossible for us to use. Therefore as UM uses this sensible approach, of time management, we stick with UM.
If we switch to one or both of the two RadiusManager timer models, we will either lose a lot of customers very fast and make them very angry (especially those that pay for a day close to midnight) or we have customers who pay for one hour and only use it for a few minutes every day for many weeks. So we then lose a lot of money.
