The study found that Austin is home to 91 wireless companies, over half of which are pure wireless ventures. Nearly half of the wireless companies, 43 percent, are involved with Wi-Fi. Most are small, with 80 percent employing 50 people or less. Through 2008, the researchers predict that the number of workers in wireless firms in Austin will grow an average of almost 19 percent.
