The LoRa Alliance is
hosting its Q4
Members' Meeting in
Tokyo this week, with
its LoRaWAN Live
showcase taking place
today, October 25, in
the Hilton, Tokyo 2,
Shinjuku, Tokyo, 160-
0023. LoRaWAN Live
will feature
presentations and
demonstrations from
our large member
ecosystem covering the latest technology and key use case and deployment stories. Japanese
member company and event sponsor, M2B Communications, will deliver a keynote titled
"LoRaWAN and disaster prevention," during the morning session. The Marketplace will feature
demos from the following companies: Actility, Daliworks, Kiwi Technology, LoRa Alliance, M2B
Communications, Macnica, Manthink, Multitech, Murata, RedwoodComm, Semtech, SenseWay,
STMicroelectronics, Tektelic, Viloc and Yokogawa Electric.
About the New LoRaWAN Specifications
The three new specifications include:
o LoRaWAN Application Layer Clock Synchronization Specification v1.0.0
o LoRaWAN Remote Multicast Setup Specification v1.0.0
o LoRaWAN Fragmented Data Block Transport Specification v1.0.0
These specifications were developed to allow the LoRa Alliance ecosystem to perform FUOTA in
a standardized way. The ability to update devices remotely is critical for the IoT, where many
sensors are in remote or difficult locations to reach but may require updating. Making FUOTA
part of the specification contributes towards future-proofing LoRaWAN and ensuring that
LoRaWAN devices will continue to operate over long lifetimes.
Together, the new specifications enable FUOTA, however, three separate specifications have
been issued because each can be used independently. For example, remote multicast setup
protocol can be used standalone to send messages to a group of end-devices; fragmentation
can be used on its own to send a large file to a single end-device (unicast); and time
synchronization also can be used as a standalone capability.
As is true for the LoRaWAN protocol as a whole, security was a strong focus of this
development effort and is addressed in the Multicast and Fragmentation specifications. For
