IEEE 802.11中IEEE 802.11中的扩大参考广播基础设施同步议定书作为IIoT的启动器 (Extending Reference Broadcast Infrastructure Synchronization Protocol in IEEE 802.11 as Enabler for the IIoT)

Realizing the industrial Internet of Things, more andmore mobile use cases will emerge in the industrial landscape,requiring both novel concepts and smooth integration into legacydeployments.Since accurate time synchronization is particularly challengingfor wireless devices, we propose a concept for simple but accuratesynchronization in IEEE 802.11 wireless local area network thatextends the Reference Broadcast Infrastructure Synchronizationprotocol, and a suitable integration of IEEE 802.1AS that is partof the IEEE time-sensitive networking standards. In addition,the concept is evaluated with a testbed using commercial off-the-shelf hardware and a realistic discrete automation demonstratorequipped mostly with industrial components. By using the afore-mentioned devices for wireless communications, this concept canbe directly applied in existing industrial solutions, thus achievingthe proposed results. It is shown that the achieved synchronicity issuitable for a wide range of mandatory mobile use cases, which aremost important for a fully functional industrial Internet of Things.
