When I went to Vocera’s website, I was amazed that they had in production a product much like the communicator badges worn in the Star Trek series of television shows and films. These badges allow voice communication wirelessly and hands free between users on a network. While I haven’t seen the products in actual use, the concept videos on the company’s website are very compelling.
As they continue to support standards-based networks, like 802.11, the product might be implementable in a more public way, similar to today’s IP telephone products. At a minimum, the geek in me loves the product. Long-term, this type of thing could replace cell phones.
