Introduction to WiFi/Mesh Networking

Workshop Description

This workshop will cover the basic knowledge needed to configure and deploy a WiFi mesh networking node. It consists of several short modules. Each module is followed by a brief hands-on exercise. The modules cover network basics such as addressing; network equipment such as switches and routers; network design such as mesh; field power; and device configuration such as mesh nodes and VoIP telephones.

Intended Audience

Any new or experienced hams interested in building and deploying WiFi networks, particularly those using the Broadband HamNet mesh networking software.

Prerequisites

• Valid Technician class or higher Amateur Radio license

Format

In person, 3 hours

Participants must bring

• Portable (laptop, netbook, etc.) computer with:
  • Required: Ethernet connector
  • Optional: WiFi capability
  • Windows is preferred. The first exercise assumes you have a Microsoft Windows PC.
  • If Linux, you must know how to configure the Ethernet and WiFi interfaces.
  • If Mac, make sure you have the Firefox browser. We have seen problems with Safari.
• Standard Ethernet patch cable (straight-through, 5 ft minimum length)
• Download and install the free program [Angry IP Scanner](http://angryip.org).
  • If you don’t have a Java RTE installed, it will prompt to download and install that as well.
  • We will use this program in the exercises to scan the local network
• Mesh node
  • If you have a mesh node, bring it. Make sure it has [BBHN](http://www.broadband-hamnet.org/) software v3.0.0 or greater.
  • If you don’t have a mesh node, there will be units available for you to work with.
• Notebook and pen/pencil
• Copy of workshop materials (below)
