Take a look at the big picture in the Mappers Roadmap. Join the Mappers newsletter to stay up to date on new and upcoming features. It aggregates coverage measurements into a heatmap, radar plots and alpha shapes. This tool has the ability to show raw survey results for devices and hotspots. Ĭoverage Map is a third party tool that draws heatmaps for LoRaWAN networks. While Helium Mappers shows an aggregate view of the network coverage, Cargo can display specific mapper devices by name, and their most-recent position reports. It shows the current location of these devices, along with the coverage of the network as an H3 hex grid. Helium CargoĬargo is an evaluation tool for LoRaWAN GPS tracking devices. Helium Mappers uses the H3 hexagon tiles to aggregate survey results and provided statistics. The map also shows the Helium hotspots that have provided coverage to these areas. Helium Mappers lets you see the areas that have been explored by participants in the coverage mapping project. If you want to fly a GPS tracker on a balloon or aircraft, please do not contribute this data to the coverage map.īe sure to check out the ongoing conversation in the dedicated #mappers channel on the Helium Discord Server.

We would like the map to indicate the expected coverage a standard sensor device would experience. By mapping real-world coverage, network users can understand where sensor deployments are likely to have success connecting to Helium.Ĭoverage mapping should only be done from ground level, or slightly above it. I would really like to hear back from you about how you measure and monitor your network availability.Coverage mapping is a crowd-sourced effort to build a true-signal coverage map of the Helium network across the globe. I hope not to have caused too much headache with this article. If in one-year time interval, the Internet connection never failed, while the VPN tunnel was unavailable for 1 day, then the value of the overall network availability for that location is: These values should be set and discussed with the business architect.įor example, let’s assume that 80% of the business applications used by the users are external (Internet) and that the remaining 20% are internal (VPN). The two weights in the formula should be based on the percentage of work that is dependent to that specific resource. Network availability = Weight external_apps x Network Availability Internet + Weight Internal_apps x Network Availability VPN In this case, network availability can be calculated as the weighted average between the availability of the Internet connection and the availability of the VPN tunnel: However, this is not realistic because, on the other side, a failure of the VPN tunnel would still impact the access to internal applications but not external applications (partial outage).

We could calculate network availability based on the uptime of the Internet connection, because if the Internet goes down, it will affect both internal and external applications. What is the network availability value if the VPN tunnel is down, but not the Internet connection? How does this value change if the Internet connection goes down? Users at each remote office need to access a mix of internal applications across the VPN tunnel and external services via the local Internet connection. Each office connects back to the headquarters via a VPN tunnel. Let’s take the case of a medium-size enterprise that has several remote offices with their own Internet connection. While the formula to calculate network availability is fairly simple it can be tricky to determine what should be included in the calculation. The central server also generates availability reports for each agent. NetBeez can monitor a specific resource down to one-second interval with PING. The important thing to keep in mind is that, in order to generate five nines reports of network availability, it is necessary to use a tool that provides one-second accuracy. Ideally, most enterprises (and cloud service providers) are aiming to achieve five nines (99.999%). With this formula we can derive the maximum amount of downtime that a service can suffer in order to meet its Service Level Agreements (SLA): Availability The formula most commonly used to calculate uptime is the following: Switch uptime is 2 weeks, 2 days, 2 hours, 30 minutesĪvailability is the percentage of time, in a specific time interval, during which a server, cloud service, or other machine can be used for the purpose that it was originally designed and built for.
