NB-IoT and LTE-M are pillars of IoT connectivity and at the core of the future 5G IoT connectivity. They are prime candidates for any critical infrastructure deployment. The number of devices to be deployed will increase over 20x in the coming years. Battery life, energy consumption, and high-density operations with minimal network usage will become critical to the continued success of these deployments. Acklio SCHC takes cellular IoT to the theoretical limit of what is possible through a simple software update.

SCHC (Static Context Header Compression, RFC 8724) is the new generation of compression and fragmentation defined by the IETF. It allows for a communication network to reach the theoretical limit in terms of efficiency. SCHC takes advantage of the predictable nature of IoT traffic and avoids synchronization between network entities. In this way, it considerably reduces the volume of data carried over networks, and thus the efficiency of all parts of the system.

At its core, SCHC enables the highest level of efficiency on a scale never achieved before, while ensuring standards-based end-to-end security and interoperability. Typical use cases, representing billions of devices, include smart water, smart gas and smart electricity meters, EV charging stations and industrial systems.

As the pioneer and worldwide leader of SCHC, Acklio provides the reference SCHC implementation for any scalable project launched globally. It brings to operators, device manufacturers and integrators an industry-grade off-the-shelf modular software suite, endorsed by key market players and field-validated by utilities.

In addition to efficient IPv6 over NB-IoT/LTE-M, Acklio SCHC integrates the most-efficient end-to-end, scalable security layer based on standard DTLS with CID. A unique IoT VPN service built on-top of it provides super-efficient, end-to-end secure IP-based communication to any device or gateway.

Building a service with Acklio SCHC is a seamless, entirely plug-and-play process that delivers immediate benefits in terms of reduced data usage (40%-90% less data), improved energy efficiency (30%-70% less energy consumed by the communication module), and more devices in the network (up to 7x more per cell). Combined with the leading performance of the Sierra Wireless HL78 module series in terms of both power efficiency and high coverage at 23 dBm to 26 dBm, this translates directly into tangible ROI for all parties involved.

Acklio, together with Sierra Wireless, today brings in a world-first: an efficient, secure, SCHC-optimized communication stack on a cellular LPWA module that also supports an integrated SIM for seamless operation and accelerated go-to-market for its customers. This is available on three Sierra Wireless LTE-M/NB-IoT module variants: the HL7845 with support for public mobile networks and dedicated 410/450-MHz networks, and the HL7810/HL7812 for public mobile networks with extended public band supports.

Acklio is adding the full range of NB-IoT/LTE-M connectivity options to its developer program, including a comprehensive set of tools to learn, prototype and showcase IP-based systems, with access to:

  • Acklio Cloud platform,
  • Acklio SCHC embedded library with reference designs for varied target environments,
  • IoT VPN and super-efficient DTLS stack (SCHC/CID),
  • Turnkey example applications for a smooth onboarding,
  • And the full technical documentation.

Access is free for up to 50 devices. To date, the kit includes reference designs for modules and shields, including Sierra Wireless. The Acklio Cloud platform is available for IPv4 and IPv6 NB-IoT/LTE-M networks, as well as for Non-IP Data Delivery networks.
