Hi,
We are testing protocols on our lab platform and we would like to simulate
communication 2 types of communication :
- From terminals to service platform using a 3G (HSPA / HSPA+) Access
connection
- From terminal to service platform using a WiFi Access connection
We are using dummyNet to simulate the links so we are interested in IP
characteristics layers for Packet loss Rate, bandwidth and latency. Values
depends on multiple factors, but we would like to know what mean values are
considered when services are deployed.
Currently we are considering the following values. Packet Lost Rate for L2
seems 7% for Wifi and 5% for 3G. We are wondering how L3 is affected?
Parameter | Wifi (802.11a/g) | 3G (HSDPA)
Latency 100 ms 60 ms
Bandwidth 5 Mbps 3 Mbps
Packet Lost Rate XXX XXX
Any comment links will be appreciated.
Regards,
Daniel
