On
September 15, 2005, Denny Arsic from Microsoft presented Mobile 5 at the
Indiana Windows User Group (IWUG)
annual "Bash". During that presentation
attendees were shown
integrated technology that pushes email to mobile
devices as soon as the email arrives at the Exchange
server. It allows administrators to protect the mobile
device and control the mobile device from the Exchange
server.
In October Microsoft released Exchange SP2,
shortly followed by the Active Sync Web administration
too, which provided the technology needed on the server
end. The technology needed on the mobile device end,
Accessory Kit Upgrade 2 (AKU2) with Messaging and
Security Feature Pack (MSFP), is now beginning to be
released by device manufacturers and service providers.
For devices with Mobile 5, new ROMs can be downloaded
and then installed on the Mobile 5 device, allowing them to
be easily upgraded as new technology becomes available just
as service packs and updates are applied to normal
computers.
This will bring mobile devices more into the
realm of IT management. Companies will now rely on IT
departments to handle upgrades and management of these
devices. IT departments will now need to add mobile devices
to their paradigms and take more control. No longer will end
users be able to pick which mobile phone or PDA they would
like. IT departments will need to standardize on devices to
control management overhead.
There are a few things to consider with the new
push available in AKU2. First, push email is handled by
keeping an http connection open between the Exchange
server and the mobile device through heartbeats, where
the mobile device periodically pings the server. By
default, the heartbeat is 120 seconds and consists of
400 bytes.
Unless the data plan for the device has
unlimited data transfer, this can take a large bite out
of the monthly throughput. The heartbeat can be changed
to a different setting. The consensus on this is a
heartbeat every 30 minutes works well to keep the http
connection alive.
If the firewall times out the
connection between pings the device will need to
reconnect more frequently and cause errors in the event
log. To fix this, time out will need to be set to an
appropriate timeout period for your organization (ie:
thirty minutes).
