Elevation showed wire LQI better than planar. Although wire is worse on the road, Planar is worse in 45° direction.
Which is suitable wire or planar antenna of TWE (Tocos Wireless Engine) to propagate distance?
電波強度 LQI を測定した結果，高さの影響はワイヤの方がが少ない。道路上試験ではワイヤが良くないように見えるが，対角線上の距離だと平面はワイヤより劣る。
TWE (Tocos Wireless Engine) のワイヤアンテナと平面のどちらが通信距離が期待できるか。
I installed wire antenna type device #4 and planer antenna type device #5 on the bicycle at the height of 1.8 m. I measured LQI value with regard to distance as shown in Photo 10 to 13. I checked the distance by Google Map.
The street is corner at 67 m distance. #4 may have no sensing range between 17m and 67m. When their devices is on ground zero, #4 LQI increases. But #5 decreases. It seems that planar antenna is not good as wire antenna with regard to elevation.
When they put on the north east corner of the backyard, #4 and #5 LQI value are 36 and varying 12 to 18. We should choice wire type for usual application.
