RF Devices

Note: This section is for the legacy RF application that will be soon retired. Redwood Mobile is our modern graphical mobile solution that new customers should start with. See the Redwood Mobile WMS section.
Oracle Warehouse Management Cloud supports a handheld RF (Radio Frequency) device interface to access the Mobile RF terminal based application. The basic requirement for these devices are:
  • Should have a Secure Shell (SSH) app that can connect via secure encrypted SSH protocol to any configurable port number
  • Capable of supporting vt100 terminal emulation
  • Ability to display at least 24 characters by 16 lines of text, preferably 29 x 19
  • A physical keyboard should have separate alpha and numeric keys with support for Control keys

Typical RF Devices used in warehouses these days run the Android operating system. WaveLink, Termius, Velocity, some SSH applications used by Oracle Cloud WMS customers, and others can be used as well.

We recommend using a device running newer versions of Android, to also be compatible with the new Redwood Mobile appsolution. For new implementations, we recommend using Redwood Mobile WMS over the legacy RF application. Please see the Redwood Mobile WMS section for more details.

SSH Apps

Note: SSH apps may not be included with the RF Device and may need to be bought separately. The RF Device vendor may offer other SSH apps. SSH apps should be compatible with the following mentioned Ciphers, keys, and algorithms.
Ciphers Key Exchanges Macs Host Keys
aes256-gcm ecdh-sha2-nistp256 hmac-sha2-256-etm rsa-sha2-512
aes256-ctr ecdh-sha2-nistp384 hmac-sha1-etm rsa-sha2-256
aes256-cbc ecdh-sha2-nistp521 hmac-sha2-512-etm ecdsa-sha2-nistp256

aes128-cbc diffie-hellman-group16-sha512 hmac-sha2-512
diffie-hellman-group18-sha512
  • A device without a physical keyboard, using only an on-screen keyboard will have severe limitations in functionality and performance, when used with the Mobile RF WMS application. The Control key is required. The standard on-screen keyboards may not expose this key and third party software keyboards may need to be installed. Even with that, it will be quite inefficient to use an on-screen keyboard.

Note: WebRF isn't intended to be a production or high volume solution for RF. It's designed for testing purposes only. Customers using WebRF for testing should use Redwood Mobile WMS. WebRF will be retired soon.

Connection Stabilizing Software

Some customers have used connectivity stabilizing software to handle spotty WiFi in warehouse where the handheld device connects to the connection stabilization software, which in turn connects to Oracle WMS Cloud. Oracle does not test or certify such solutions and customers would be responsible for making sure it performs per their needs. Oracle will not be able to debug any issues related to such software.

Computers

To access the RF application from a desktop or laptop, PuTTY is typically used.

Note: The devices and applications mentioned here are for reference. The customer is responsible for acquiring proper licenses etc, if any, as may be required.
