hi list,
just a quick question about the new push feature for activesync/exchange...
does it use alot of bandwidth compared to having the device setup to check
for new data every 60 minutes?
i believe that it should be substantially smaller bandwidth (excluding the
size of the new data items ofcourse) will its connected to exchange?

Hi,
It's not known right now. I am unaware of any OEM that ships a rom that
supports MSFP.

Please log in for more thread options The intention is that nothing gets transferred until there is a message to
travel.
Interpreting how it might work could mean: If you are syncing every 5
minutes, but only get e-mail every 5 hours - then the new push facility will
use LOTS less bandwidth.
But if you are currently syncing every 60 minutes, and there is always at
least one e-mail message to transfer, then it is likely to use more. As it
will sync every time a new message comes in, rather than waiting and
batching them up (so the push will include the transfer overheds for each
individual message, rather than one overhead for a number of messages).

Please log in for more thread options Ricardo,
The Direct Push capability in Exchange ActiveSync uses something called a
heartbeat in order to stay "connected" to the Exchange Server. That is, the
phone client pings the server and waits for a response for a set period,
usually around 15 minutes. If a new message comes in to the server during
that time, the server responds immediately to the ping and the device
synchronizes the change - resulting in the "push" experience. If nothing
happens during that period, the client will ping again for another heartbeat
of 15 minutes.
We've done some testing with RoadSync (www.roadsync.com), our ActiveSync
Client on Symbian devices and found the following:
Assuming there is no email at all coming in, there will still be data
transmission due to this heartbeat activity.
Each heartbeat ping uses approx. 800 bytes of data.
Assuming the ping occurs every 15 minutes, all day long, that results in
about 75k per day, or roughly 2MB per month of data transmission as a low end
baseline. Any additional email traffic or attachment transmission will
result in higher data usage.
Hope this information helps.
