Thought I'd give this a stab. I like the simplicity of the cog and then i added the squares to represent data processing but it could happily do without those (as well as the aviation 'hint').
Great first entry. good simplicity, keeps the core business in there. I like partial gear better than wasting space with the whole circumference.
Inner circles don't seem to add much for me. Would be interesting to see what else could go in that space (maybe nothing! although maybe the gearness gets lost). data bits consistently the size of the one in the teeth by the S might look better, as maybe alternating blue filled and un-filled (1 & 0)?
