A few are explicitly wireless because they need to connect wirelessly to other things, like an implanted comlink, cyberdeck or rigger system.

But I believe the rule or gentleman's agreement in Shadowrun is that something you paid Essence for (you pay Essence for cyberware and bioware) is part of you and cannot be hacked. Though I believe there have been adventures where for plot reasons it was possible. Shadowrun is not entirely consistent in that regard, I'm afraid.
