I actually have quite a few reservations about this but I'll reserve judgement until I've tried it fully. Everybody using the same channel will make it more realistic i.e. you will be able to hear enemy chatter close up. It will also be confusing and kill the immersion as the PLA squad near you will probably be babbling in english. Thats why most players leave the in game voip set at the native language of each force, it adds to the immersion and makes enemy players easier to identify. Removing the need for comm rose communication in game will actually break some of the immersion for me at least.

Also everybody in one channel will just lead to some of our less mature players taunting each other when they get within earshot.

In addition 100m radius for directional voip is ridiculous, you cannot hold a conversation with someone 100m away, you certainly can't on a battlefield or in a wooded or built up area. Even 50m is pushing the boundaries of realism quite some way. In addition the bigger the radius of effect the more players that will fall into that radius the more comms noise you will have.

Personally I can see this being very popular for a while then people turning it off. I've already got secure comms with my squad and people on TS. In particular the secure squad comms (i.e. silent comms as far as enemy is concerned) is a huge advantage over real life, as even a throat mike requires talking out loud as it were. I can also see people becoming a niusance with this, we already have chat spam, over entusiastic TS use at times, imagine the added noise of hearing every remark in a 100m radius.

I think it's a great idea but will be approaching it with caution lol.
