by | Sep 23, 2019 | 0 comments

Nesyer LPWA-6LowPAN is an integrated communication module for radio-based communication. It is effective in cost, low energy, safe, compact and reliable and can be used in a mesh or star topology.

 

Features

  • All in one module. It includes 2 microcontrollers, data-storing facility, clock and RF communication subsystem. The main CPU is used for high performance computing, while other CPUs are used to keep low energy usage.
  • All components are optimised in performance and cost.
  • Low-frequency ad accurate clock source to support network synchronisation process.
  • Only 15 mm x 15 mm in measurement.
  • Uses a frequency of 920 – 923 MHz.
  • Uses standard mesh communication system which uses IPV6 based address. Standard facilities include standard CoAP and MQQT for IoT communication.
  • AES 128-based encryption system with variable dynamic keys with adjustable time intervals.
  • There are 10 I / O ports which can be used for GPIO, PWM, ADC, I2C, SPI and UART needs.

Benefits

  • The developer will be able to directly focus on the application without needing to arrange complicated hardware production and radio tuning which requires high investment funds. Moreover, the developer will not have to deal with radio communication stack.
  • Since it requires low power, the application is able to run on battery for years on end without having to change batteries.
  • Large communication area. Communication area can be expanded by increasing the transmission power with a maximum of 2 Watt (according to regulation), or using a mesh topology which will be able to relay the data plan to an infinite amount of distance.
