The more accurately you set the Antenna and Provider Settings, the more rapidly you are able to detect mobile devices.
Sometimes it might take several seconds to detect a phone, sometimes up to 15 seconds, this all depends on the range.
As the mobile devices need to reply to the request from the X-Sensor Processor with SDR (transceiving principle), you need for both the TX and RX a Directional Antenna.
You may use MIMO antennas – however we advise separate antennas for both TX and RX.
