Early Warning and Intruder Detection:

The platform for this development (UE) is based upon a credit card sized all programmable host SoC, combined with a USRP SDR RF frontend with frequency-agile wideband receive and transmit paths in the 70 MHz to 6.0 GHz range, making it ideal for a broad range of fixed and mobile SDR applications. The system is being powered via GaAs solar panel and further research is being done to make use of energy harvesting via a Thermoelectric Generator.

The sensor shield is equipped with a Flir Lepton LWIR Thermal camera mounted on a mini turret with a FOV of 20° scanning the round circle in 15 seconds. The camera control module, as well as the image capture, video processing, alarms, and pattern analysis are being performed on board, with an option of performing these functions in the control room where the video is viewed on the GUI.

The processed video streams via LTE to the Smart Wireless Laboratory eNB (Small Cell). The LTE UE stack does not make use of a USIM (SIM Card) module but rather a software USIM Card and USIM Card API which have been combined to provide additional security for securing sensitive data, and minimal working sets to authorize in the LTE network.

This platform has also been designed for various sensory applications to function within IoT and M2M vertical industries such as:

  • Smart Cities
  • Smart Environment
  • Smart Water
  • Smart Metering
  • Security and Emergencies
  • Retail
  • Industrial Control

The flexibility of the SDR spectrum range allows for connectivity via WiFi, 802.15.4 / ZigBee, LoRaWAN 868 - 900/915 - 433MHz, TVWS (IEEE 802.11af), and LTE.

Currently the focus of Smart Wireless Laboratory is based on LTE developments with a migration roadmap to 5G.

LTE Stack Features:

  • Baseline – Release 8, 9 and 10:

–             All supported bandwidths (1.4 MHz – 20 MHz)
–             DL MIMO 8x8, UL MIMO 4x4
–             Carrier Aggregation (two component carriers)
–             Macro-, Pico-, Femto-cell deployment
–             Advanced algorithm for radio resources scheduling

  • Possible extensions towards newer releases:

–             Enhanced interference coordination
–             Enhanced Carrier Aggregation (more component carriers)
–             Operation in unlicensed spectrum
–             UE designed for long battery life

Smart Wireless Laboratory Key Differentiators:

  • Functionalities
  • Support for carrier aggregation
  • Support for interference management and coordination
  • Support for traffic overload
  • Resource scheduling optimized for the needed traffic type (e.g., video streaming)
  • UE categories supporting needed traffic type (e.g., video streaming)
  • Basic network SON (e.g., self-healing) features
  • Support of software SIM
  • Support for non-standard bands

Architecture

  • Modular and transparent architecture to enable software (L2L3) portability amongst various platforms
  • Use of standard (3GPP) and industrial (e.g., Small Cell Forum) interfaces to enable further modularity
  • PHY optimized for a selected target platform

Ease of use

  • Possibility to setup a private network or interface with other networks
  • Scalable eNB capacity (Femto, Pico cell)
  • Porting which includes a broad range of customization
