ue-requirements

The end use equipment requirements are relatively simple.

Long term the CAHN system must support all devices which would typically attach to the target network, wiht appropriate software update.

For the purposes of the development cycle we can distil the following elements

UE-Rec-001 Developer support​

The EU device must support developer mode, SDKs and the capability to add software updates to the system

UE-Rec-002 Networking support​

The EU device must support the target networks. This is likely to be through attached devices, through SPI, I2C or USB interfaces.

Essenital networking capabilites are

  • WIFI module (likely to be built in)
  • 5G module
  • LoRaWAN module
  • Satellite - is likely to be bridged through WIFI, rather than having its own interfaces

UE-Rec-003 Secure element​

The UE device must support a secure element or TPM in order to demonstrate deep security capability

UE-Rec-004 User interface​

The UE device must support a basic user interface (or API) to demonstrate user interactions. HTML via WIFI should be sufficient

UE-Rec-005 Power​

The UE device must power supply: ideally both plugged in and battery

Here are some additional user equipment requirements using the provided form as an example:

UE-Rec-006 Storage​

The UE device must support sufficient storage capabilities to handle the intended data load. This includes support for:

  • Internal storage with a minimum capacity of 32GB.
  • Expandable storage options such as SD cards up to 128GB.
  • High-speed data transfer capabilities.

UE-Rec-007 Sensor Integration​

The UE device must support integration with a variety of sensors to monitor environmental conditions and system performance. This includes:

  • Temperature sensors.
  • Humidity sensors.
  • Accelerometers.
  • Gyroscopes.

UE-Rec-008 Operating System Compatibility​

The UE device must be compatible with major operating systems to ensure broad usability. Supported operating systems include:

  • Windows 10 and above.
  • Linux distributions.
  • Android.
  • iOS.

UE-Rec-009 Connectivity and Communication​

The UE device must support various connectivity and communication protocols to ensure seamless integration and communication. Required protocols include:

  • Bluetooth 5.0.
  • NFC (Near Field Communication).
  • Ethernet.
  • Zigbee.

UE-Rec-010 Data Security and Encryption​

The UE device must support robust data security and encryption methods to protect sensitive information. This includes:

  • AES-256 encryption.
  • Secure boot and firmware validation.
  • Support for VPN connections.
  • Regular security patches and updates.

UE-Rec-011 Audio and Video Capabilities​

The UE device must support basic audio and video capabilities for communication and media playback. This includes:

  • Built-in microphone and speaker.
  • Support for video playback in HD resolution.
  • Audio output through 3.5mm jack and Bluetooth.

UE-Rec-012 Physical Durability​

The UE device must be physically durable to withstand harsh environments and usage conditions. This includes:

  • Water resistance (IP67 or higher).
  • Dust resistance.
  • Shock and vibration resistance.
  • Operating temperature range from -20°C to 60°C.

UE-Rec-013 Software Update Mechanism​

The UE device must support an efficient and reliable software update mechanism. This includes:

  • Over-the-air (OTA) updates.
  • Manual update via USB or SD card.
  • Support for rollback in case of update failure.

UE-Rec-014 Localization and Language Support​

The UE device must support multiple languages and localization features to cater to a global audience. This includes:

  • Multilingual user interface.
  • Support for region-specific settings (date, time, currency).
  • Localized customer support and documentation.

UE-Rec-015 Compliance and Certification​
