Developing with Weightless

The future of LPWAN

Weightless is much more than a simple alternative to inferior proprietary IoT connectivity technologies. It is measurably better in every key design respect - better in ways that affect real users and developers, better for you. Basing your IoT design on Weightless technology is a commitment to next generation performance and a future proofed commercial platform.

So how is Weightless different? We have created a detailed description of the technology running to some 10000+ words to explain. Prefer a shorter summary? Don't worry, included in the report are details of 8 core features your IoT technology must support - your quick guide to the essential elements of a successful LPWAN product design. We include sections on:

  • Cost
  • Capacity
  • Open Standard
  • Power
  • QoS
  • Range
  • Reliability
  • Security

For those ready for a deep dive into the detail, the LPWAN Technology Decisions: 17 critical features paper provides in-depth analysis of the competitive advantages that differentiate Weightless from alternative proprietary technologies. We explain in detail how Weightless moves the IoT connectivity game on, offering carrier grade performance measurably ahead of ordinary LPWAN technologies. 

In each section we set out precisely how Weightless addresses common issues for IoT connectivity developers. We also provide comprehensive additional technical detail, sent separately over the coming weeks, on the core differentiation from every other technology. If you're a developer and want to understand the nuts and bolts of Weightless technology, download the paper today and receive the detailed technology breakdown in 15 separate chapters.

  • FDMA+TDMA in 100kHz & 12.5kHz narrow band channels offer optimal capacity for uplink-dominated traffic from a large number of devices with moderate payload sizes
  • Operates over the whole range of license-exempt sub-GHz ISM/SRD bands for global deployment: 433/470/780/868/915/923MHz
  • Adaptive power control and data rate from 625bps to 100kbps to optimise radio resource usage depending on device link quality
  • Time-synchronised base stations and flexible channel assignment for efficient radio resource scheduling and utilisation in large-scale deployments
  • Supports paging capability, both network-originated and device-originated traffic
  • Forward Error Correction (FEC)
  • Cell re-selection (handover, roaming)
  • Fully acknowledged communications
  • Supports narrowband channels (12.5KHz) with frequency hopping for robustness to multi-path and narrowband interference
  • Supports licensed spectrum operation
  • Power consumption in idle state when stationary below 100uW
  • AES-128 authentication and encryption
  • Support for over-the-air firmware upgrade and security key negotiation or replacement
  • Brings the reliability and performance of cellular technologies at a fraction of the cost by avoiding any legacy or backward-compatibility concerns
  • Ensures interoperability between the manufacturers
  • Provides for multivendor support to stimulate ongoing innovation and minimise end user costs
  • Royalty free IP minimises production costs
