Infarm Indoor Urban Farming INF001-CL LTE Data-Only SMT World-Module User Manual

Introduction

he Infarm Gateway acts as the bridge between the internet and the onboard control  systems of the Acre and Instore farms.

The Infarm Gateway runs and maintains the following services:

• Link between Infarm BE and Farm
• Controls internet connectivity directly (cellular)
• Facilitates and manages local communications
• Runs business logic services (growing schedules, recipes, etc..)
• Provides local access to the Farm (over BLE)
• System updates (gateway services and controllers firmware)
• Logging services.

Antennas

The antennas must be professionally installed when fitted to the ACRE/ Instore systems. Please check the installation guide before installing the antennas.

ACRE

SMW-414 multiband, 4-cable Global Cellular/LTE, WiFi & GPS 

The SMW-414 Series antennas feature 4 antenna elements in one radome. Cable 1 can cover the traditional GSM/CDMA frequencies, 700 MHz LTE, 1.7 & 2.1 GHz WS/UMTS, and LTE/WiMAX at 2.5 or 3.7 GHz, all on a single board. This antenna is ready for any 4G or 5G rollout but is also compatible with earlier generations such as GPRS. The antenna also covers 2.4/5 dual-band WiFi on Cables 2 & 3. This can be used for two separate WiFi modems or for a WiFi MIMO modem. The antenna is enclosed in a 4.2”D x 3.2”H (107 mm x 81 mm) weatherproof radome, and supplied with all mounting hardware and a sealing gasket.
