LigoDLB Propeller 2/ 5 The Propeller devices from LigoWave have a unique antenna characteristic changing mechanism for simple vertical or horizontal orientation based on the use case of the device. It is recommended to assemble the propeller in a horizontal position for a client mode. This way the antenna beam-width in the vertical polarization will be narrow (15° on a 5 GHz model and 35° on a 2 GHz model) and on the horizontal polarization (60° on a 5 GHz model and 70° on a 2 GHz model). This ensures easy antenna alignment when installing the device without a need to tilt it upwards or downwards. Also, based on the test results in Table 1, the signal of the base station is received better and noise coming from the surrounding devices is lower. When a Propeller is assembled in a vertical position the antenna characteristics switch and vertical polarization beam-width is wider while horizontal polarization beam-width is narrower. This antenna orientation is better for the access point mode, where wider area coverage is necessary. Propellers can be used as WI-FI hotspot APs in outdoor networks when the device is assembled vertically and the Infinity series software version is loaded. When a Propeller is assembled vertically the antenna characteristics are 60° on a 5 GHz model and 70° on a 2 GHz model for the vertical polarization and 15° on a 5 GHz model and 35° on a 2 GHz model for the horizontal polarization. This assembly is recommended for a base-station or an access point scenario. Low Cost CPE ISP CPE Low Cost CPE /AP radio
