Prior to SAPP_5003 patch, we are using kbps (kilobits per second) unit. Hence bandwidth to be converted to kilo bits and stored in the bandwidth field. Here the calculation for 5MB is 5 * 1024 * 8 = 40960 kbps.
From SAPP_5003 patch onward, the unit changed to KB/s (Kilo bytes per second). Hence bandwidth to be converted to Kilobytes and stored in bandwidth field. Here the calculation for 5MB is 5 * 1024 = 5120 KB/s
