The decision to use external antennas should be made based on performance evaluation of how the product
performs when placed in the desired location within the vehicle or fixed site.
5.5.1 Cellular
The cellular connection supports MIMO (multi-in multi-out) for LTE Category 1 and 4 models. For best
performance ensure both primary and secondary cellular antenna connections are made to an antenna that
supports diversity or to two separate antennas.
CTM-ONE M GLOBAL B1,2,3,4,5,8,12,13,18,19,20,25,26,28
CTM-ONE PLUS B2,4,12,13,14,66,71
CTM-ONE/PLUS II,IV,V
CTM-ONE M 850/900/1800/1900 Mhz
5.5.2 GNSS
The GNSS antenna should be an active type of antenna with a gain of at least 26dB and compatible with a 3.3
volt DC supply provided directly by the CTM-ONE via the coax cable. The antenna installation should typically be
on an upper horizontal surface of a vehicle or building with a clear 360-degree view of the sky.
Connect a suitable GPS antenna to the port labeled “GPS”. For best performance select a GPS antenna that
supports GPS/Glonass/Beidou/Compass/Galileo/QZSS (GNSS) constellations.
5.5.3 Wi-Fi/Bluetooth
Local Wireless via Wi-Fi (802.11bgn) and Bluetooth (802.15.1) requires an external Wi-Fi antenna connected via
a reverse polarity SMA connector
