Jamming of "public signals" such as used by Mobile 'phones is not all that difficult. The problem for the Jammer is that the mission is short lived and the "business benefit" is eroded by the nature of mobilityand that they would be discovered fairly quickly. The real benefit may come from being able to jam anything in the 2.4GHz band - WiFi, Bluetooth etc. However, this is rather difficult, remember that it's an industrial (or free) band and devices are designed to cope with severe interference (eg. Using a bluetooth device in the kitchen when the microwave is on). Sounds like another route to market for expensive consultancy to me...
