RMNet & PPP – Android Data Protocols

In Tutorials

Native Android devices make use of the PPP type data connection wherein the connectivity is faster compared to RMNet. When Android was ported to the HTC HD2, a native Windows Mobile phone, the RMNet type data connection caused slow connectivity requiring higher browser time-outs. The PPP (Point-to-Point Protocol) type on the HD2 performed better than RMNet but with a drawback of unstable connection which disconnected at time, to recover which you would have to turn off and on your data connection or put your phone into airplane mode and back out of it.

So basically it depends on the user whether they would like to have a stable reliable yet slower connection or a faster but unreliable connection. However the frequency of data disconnection on PPP is not that much and bringing it back is not difficult too.

Switching between RMNet and PPP is not tedious. If you can find ‘ppp’ folder under root /system/etc/ then your Android is already ppp enabled; just deleting the ppp folder will enable back RMNet, of course you need root privilages for that.
