  • Improving cellular signal for mobile vehicles

    Dropped calls, undelivered and unreceived texts, and slow data speeds on the road can be frustrating and downright unsafe thus the need to improve signal strength in emergency vans, recreational vans, cars, and trucks. need to be constantly connected. This can, however, be inhibited by factors that cause cell phone signals to be blocked, absorbed or altered thus affecting communication.

    Internet access is needed despite the fact that there are several 'dead zones' in the coverage area where personal mobile phones may fail to get coverage. Mobile antennas are needed to help in overcoming the sometimes huge losses that occur due to obstructions such as the vehicle's body and not really boosting weak signals.

    They offer signal gain which ranges from 3dBi-6bBi at maximum. In order to get an idea of whether a mobile antenna is going to solve a 'dead zone' problem, one needs to test how the hotspot operates outside the vehicle in this zone. A mobile antenna comes in handy if the hotspot works efficiently outside the vehicle but does not receive a signal inside the vehicle.

    For this application one can consider LTM301-3C3C2C-WHT-180. Some other choices for 4G LTE antennas can be LTM3013C3C2CBL180, LTM501-3C3C3J3J2C-BLK-18 and LTM501-3C3C3C3C2C-BLK-180.

    If still no signal at all is being received in the 'dead zone' while having the hotspot outside, a mobile antenna alone will not be able to solve this problem unless with the support of signal amplifier kits.

    For best MIMO performance, it is recommended to have 2 antennas (one for each port) separated as far as possible (MIMO works best when each antenna receives a signal uncorrelated to the signal on the other antenna hence best to separate the antennas as much as possible). A single antenna can also work well on the condition that it is connected to the primary antenna port and not the AUX port.
