Traditional deployment of IMSI Catcher technology has been in vehicles, to allow for high power output, or in covert backpacks, for close quarter work, where vehicles are impractical, or would raise suspicion. IMSI Catchers have been deployed in aircraft for search & rescue and border patrol and, more recently, in UAVs or drones. As dedicated platforms, these are proprietary and tend to be expensive and quite large, not easy to deploy rapidly.
