5 The Digi XBee ® Ecosystem ™ offers one of the industry's broadest selection of pre-certified wireless networking options, allowing you to easily start, extend, and scale your solution. Many of the largest energy companies, utilities, industrial and transit agencies rely on Digi's embedded RF solutions, gateways and accessories. Digi XBee RF hardware, software and expert resources, ensures maximum reliability, security and scalability for your M2M mission-critical wireless needs. With design flexibility, including compact and compatible through-hole and surface mount (SMT) form factors, the Digi XBee and Digi RF solutions provide a solid foundation for adding wireless M2M and IoT connectivity. The Digi XBee ® Standard Why Choose Digi XBee3™ Zigbee RF Module? Future Proof Footprint Mesh Networking ZigBee is an open, global wireless standard designed for resilience and reliability communicating through noisy RF environments common in industrial applications. DigiMesh is similar to ZigBee mesh networking, but unlike ZigBee, DigiMesh only has one node-type that can route data and are interchangeable. Thread is an open, global, IPv6-based, low-power mesh networking protocol that is simple to setup and deploy. Point to Multi-point 802.15.4 is a standard which specifies the physical layer and media access control and is ideal for applications requiring low latency and predictable communication timing. 802.11, or more commonly known as Wi-Fi, has a variety of sub- protocols represented by the suffix a/b/g/n/ac, each with varying degrees of bandwidth. LTE Cellular Networking LTE Cat 1 technology makes LTE viable now for M2M and IoT applications. LTE Cat M1 is an IoT-centric flavor of LTE designed for sensor applications and devices requiring lower throughput. LTE Cat NB1, also called Narrowband-IOT, also supports lower bandwidth applications and addresses challenges of poor signal strength and range limitations. .96" .87" 1.297" 1.33"
