How is my bandwidth measured ?

Bandwidth is measured by counting all packet traffic originating from & destined to the session IP address of your connection. Bandwidth consumption is measured by counting all packet traffic originating from and destined to the session IP address of your connection.

This consumption is session based and is only reflected on the bandwidth monitor once a session is closed, meaning that if the session lasts over several days it will only be reflected on the bandwidth consumption monitor on the day the session is disconnected.

The traffic measured includes retransmitted packets and packets dropped (eg by firewalls and antivirus programs on subscribers computer). We are currently unable to exclude or isolate such traffic from the counters. However the measurement of consumption is conservative and we tend to err to the benefit of subscribers in the algorithms used.

Furthermore, once the consumption quota has been reached we allow for a small amount of grace usage before throttling a connection. Please note that traffic generated unbeknown to subscribers such as spyware and virus traffic will be accumulated towards subscribers bandwidth consumption.

It is advised that appropriate measures (such as antivirus, firewalls etc) are used to ensure that your systems are securely maintained. To correlate traffic consumption with the monitors available, it will be useful to use a session based monitor such as Magitime, which is freely downloadable on the Internet.

What affects the signal of my iBurst wireless connection ?

Good Locations

Areas that aren’t too built up or dense in other words close to window with not too many trees in the way, not on the floor, rather a window sill.

Bad Locations

Electrified fencing – If signal goes through elecritified fencing the signal can deteriorate.
Tennis court fencing – Signal going through tennis court fencing to your base station can deteriorate throughput.
Dense tree growth – If in line with your base station, can deteriorate signal.
Burglar proofing – Can cause your signal to deteriorate. Place device antenna past the steel bars.
Walls – Walls bounce signal. Try to place the device to have a clear line to the base station.
Window tinting – Certain types of window tinting deteriorate signal quality.
Security gates – If working in a office with a security gate the bars may deteriorate the signal quality.
Steel window blinds – They can reflect your signal. Open them to improve signal.

What operating system works with iBurst ?

The iBurst system works with:

Windows XP
Windows 2000
