The heavyweight high-tech companies Intel, Google, Dell, HP and Microsoft have hit a setback in their quest to gain FCC approval for the use of unlicensed TV white space for WiFi services. In March, the companies, together called the White Space Coalition,Â delivered to the FCC two WiFi devices that the group says operates in this spectrum without interfering with high-definition TV. However, the FCC's Office of Engineering and Technology has found through preliminary trials of the prototypes that "the transmitter in the prototype device is capable of causing interference to TV broadcasting and wireless microphones." The FCC, which appears to highly favor the white-space concept, stressed that the tests were preliminary, which is an indication that it will keep studying the concept.
