Smart Radio LTE Failover: Introduction
This application note describes how to use
LTE as a failover for the Smart Radio’s Mesh Rider wireless link. Smart Radio
LTE Failover is an optional add-on license to the Mesh Rider OS to create
highly resilient private wireless networks. The Smart Radio’s Mesh Rider link
creates a high throughput, long range resilient wireless network. However,
there are circumstances which could lead to the link being broken such as obstacles
impeding a good line-of-sight. In such situations, it maybe useful to have an
LTE link as a backup.
is shown that the failover and recovery
times between Mesh Rider network and
LTE network can be as short as 1 seconds.
This application note is organized into the
Radio + LTE Network Diagram
Smart Radio LTE Failover: System Overview
System Overview The system which we will demonstrate is shown in Fig. 1. Fig. 1 – LTE Failover System SIM Cards In this demonstration, we use SIM cards that support Internet of Things and M2M connectivity. The LTE service provider should be able ...
Smart Radio LTE Failover: Testing
Testing As a first test, we performed a hard disconnect on the Mesh Rider signal while pinging one radio from the other. The ping was performed at a 1 second interval with a 1 second timeout. From the results, only one sequence number was missing ...
Smart Radio LTE Failover: Device Configuration
Device Configuration In our example, we assume that we have PC 1 connected to Smart Radio 1 at ETH0, and Smart Radio 1 is connected to LTE Modem 1 from ETH1. Likewise, PC 2 is connected to Smart Radio 2 at ETH0 and Smart Radio 2 is connected to LTE ...
Smart Radio LTE Failover: Hardware Setup
Hardware Setup Fig. 2 shows the hardware setup used in this guide. Fig. 2 – Hardware Setup Of note is that ETH1 should be connected to the LTE Modem. Aside from that, the Smart Radio is setup for typical usage.
Smart Radio GCS Reference Design: Introduction
Introduction In this guide, we detail the design of a Ground Control Station (GCS) using the Doodle Labs Smart Radio. There are several available form factors in the Smart Radio family, and we will discuss how the Wearable Smart Radio or the ...
