This paper proposes a network system to manage Smart Farm based on Long Range (LoRa) and IEEE 802.11ac ad-hoc network. In greenhouse environment, there are irregular data transmission fails caused by plants. To enhance stability of wireless communication, IEEE 802.11ac consists inside of greenhouse ad-hoc network operated with a routing algorithm, namely Wi-Fi Classification based-RSSI (WiCR). Moreover, outside of greenhouse, LoRa is used for designing a remote control system. The remote control system can cover 21km range on Line of Sight (LOS) condition. We aim to prove stability of IEEE 802.11ac ad-hoc network in the plants and test capability of the remote control system using LoRa on LOS and Non Line of Sight (NLOS) conditions. With this performance evaluation, we will provide the optimal solution to various greenhouses.
