X.25 vs Wireless Technology

I’m to write out a technical report on 2 network technologies, to Compare and Contrast X.25 with Wireless Technology.

Now here’s my dilemma:

X.25 is a rather old technology and not really in use at this age of time. All i know is that it’s very reliable as it’s permanently connected, thus no packets will get lost.

Wireless technology is a hot topic these current years, however the scope is too wide. I simply have no idea where to start.

Technical papers for both technologies are scarce.

Therefore there’s an urgent need to ask if anyone could tell me what’s the main point of focus in comparing and contrasting the two.

Also, any good references will be greatly appreciated. Thanks!
