I've been reading up every couple of weeks on Exchanges' new direct push technology that is going to compete with Blackberry.
I've found articles in the past that describes how it'll function in that an http connection (tunnel) is maintained between the device and the server. So my question is what is the bandwidth overhead of this continous http connection to the exchange server?
My company already utilises Blackberry for the sales staff when they are out of office. But seeing as I am not a revered sales engineer I am not be supplied with a blackberry, nor do i desire one to be honest. However I am in control of the company's exchange server and when Service Pack 2 is finally released and tested I will update. I also plan to aquire the Mio A701 when it is released in december.
I'll therefore be able to utilise the direct push feature. But seeing as I'll be paying for the amount of traffic that my device consumes I'm worried about the cost that this constant http connection will incur.
Anybody able to shed some light on this for me?
