One area of higher tech that is usually overlooked, but mentioned in the rules somewhere, is that as higher technology improves an item it doesn't just mean it is better at blowing things up, or send signals farther, etc., it can also mean it becomes smaller and lighter. Or use less energy.
So at TL-16+ I have IMTU things like FGMP-15 type weapons that are the size of an SMG, or use magazines instead of a backpack. Gauss rifles that will fire 20mm "profiling" rounds that key in on your particular data signature, heartbeat, heat, odor, etc.. A pocket comp that is built into your hand / arm and runs off the power generated by your metabolism. Short range comms that are fitted into your jawbone. Meson guns the size of autocannons. Etc.....
