Five Points to Help You Evaluate Your Wireless Devices in AMH Systems

Jan 05, 2019

Automated material handling (AMH) systems, which include the AS/RS (automatic storage and retrieval systems) and AGVs (automated guided vehicles), are modern-day “conveyer belts” that play a key role in manufacturing facilities and warehouses around the world. These machines have taken the manufacturing industry by storm and are here to stay. However, behind every successful AMH installation is a powerful wireless solution that provides the synergy between the machines and humans.

Let’s go through the following five challenges and see how your wireless devices measure up with respect to suitability for AS/RS and AGV systems:

Challenge 1: Wireless Roaming Performance

• Is wireless roaming performance affecting your operational efficiency?
• Are the number of APs and clients deployed at your site more than you can handle, resulting in undesirable results?
• Do you have to tolerate system downtime because of seconds-long client handover times?

Challenge 2: 802.11n Support and/or Compliance

• Are your wireless devices built on 802.11n wireless standards?
• Is it possible to enable your wireless devices for 802.11n features?

Challenge 3: Electrical Interference Protection

• Are you facing disruption of wireless connectivity in your AMH system that can be attributed to inrush current?
• Are the antennas or antenna extensions installed on the vehicles or shuttles prone to electrostatic discharge (ESD) from other objects, or are they affected by airborne electrostatic particles?

Challenge 4. Vibration Protection

• Are your wireless devices that are mounted on vehicles and shuttles protected against extreme vibration resulting from the horizontal, vertical, or lateral movement of the equipment?

Challenge 5: Protection Against Severe Environmental Conditions

• Are your devices protected against severe environmental conditions?
• Does the performance of your wireless device degrade with constant exposure to high or low temperatures, or constant exposure to dust and water?
