Rugged Tablets on Forklifts

The client required an embedded computing solution for its forklifts to manage storage and logistics. The project was developed in partnership with Logos Rastreamento, a tracking and RFID solutions company. The tablets and docks provided by Above-Net were to be installed on the forklifts and enable communication with the warehouse's Wi-Fi network for access to the WMS and with the external RFID reader via Ethernet port. However, some prerequisites were essential for the solution to work, including:

• Tablet and Dock should be water and splash resistant for washing and forklift operation outdoors.
• The set should allow the tablet to be removed for possible portable use.
• The tablet should be able to communicate simultaneously with the RFID reader via Ethernet port and with the company's WMS via WiFi.

The equipment specified for the solution was carefully chosen to meet all the requirements requested by the client:

• Rugged 7-inch tablet, IP67, Android 4.2, WiFi, Bluetooth, GPS, Camera
• Rugged tablet vehicle dock with lock and key, IP54 rating, and integrated USB, Serial, and Ethernet connectors

Although the specified components fully met the project's endurance requirements, there was still a major challenge: Android prioritizes Ethernet port communication over Wi-Fi when both are connected. Connecting the RFID reader to the dock's Ethernet port immediately disconnected the tablet's Wi-Fi network. Therefore, the customer's requirements were not met.

We developed a custom Android image to overcome the barrier of prioritizing Ethernet communication and meet the project's specific needs. Upon project delivery, the forklifts were seamlessly integrated with the Wi-Fi network and RFID readers via Ethernet, enabling the increased productivity and operational efficiency desired by the client.

With in-depth experience in mobility product development and complex systems integration, Above-Net is able to overcome project integration and implementation challenges.
