The primary goal of the AREDN |trade| project is to empower licensed amateur radio operators to quickly and easily deploy high-speed data networks when and where they are needed.
In today's high-tech society people have become accustomed to different ways of handling their communication needs. The preferred methods involve short messaging and keyboard-to-keyboard communication, along with audio-video communication using Voice Over IP (VoIP) and streaming technologies.
In today's high-tech society people have become accustomed to different ways of handling their communication needs. The preferred methods involve short messaging and keyboard-to-keyboard communication, along with audio-video communication using Voice over IP (VoIP) and streaming technologies.
The amateur radio community is able to meet these high-bandwidth digital communication requirements by using FCC Part 97 amateur radio frequency bands to send digital data between devices which are linked with each other to form a self-healing, fault-tolerant data network. Some have described this as an amateur radio version of the Internet. Although it is not intended for connecting people to **the Internet**, an AREDN |trade| mesh network will provide typical Internet or intranet-type applications to people who need to communicate across a wide area during an emergency or community event.

Firmware Upgrade Tips
=====================
Upgrading an AREDN |trade| node is a straightforward process accomplished using the *Administration > Firmware Update* feature on the node's web interface. Follow the procedures documented in the **Downloading AREDN Firmware** section to ensure you have the correct firmware version from the AREDN |trade| website to install on your node. The newest firmware versions have a built-in check to verify that the firmware image you selected is appropriate for the device on which you are installing it. Earlier firmware versions (3.16.1.x and 3.18.9.0) do not have these checks, so be sure you selected the correct firmware version for your device before starting the upgrade.
Here are some "best practice" tips to assist with the firmware upgrade process. These ensure that memory utilization is at its minimum on the node. The upgrade process can fail due to lack of memory, but such a failure will leave the node unchanged on its previous firmware version.
* Before starting the firmware upgrade, it may be necessary to uninstall any packages you have manually installed (for example, MeshChat or IperfSpeed).
* Disable any existing tunnels on your node before starting the firmware upgrade.
* Reboot the node immediately before starting the upgrade.
* Use a stepped approach to firmware upgrades. For example, if your node is running version 3.16.1.0 you should probably upgrade to version 3.18.9.0 before attempting to apply a newer version.
