Broadband-Hamnet (HSMM-Mesh)

Several club members are working on an initiative to build a long range, self-building, self-healing, backup Wifi IP network infrastructure for our served agencies to use during disasters (and of course for our own use when there isn't a disaster). It uses normal Wifi devices (THIS IS THE RADIO) but licensed under FCC Rules Part 97, so much higher power levels and over much greater distances.

Broadband-Hamnet (HSMM-Mesh)

Broadband-Hamnet LogoBroadband-Hamnet™ (formerly called HSMM-Mesh™)  is a high speed, self discovering, self configuring, fault tolerant, wireless computer network that can run for days from a fully charged car battery, or indefinitely with the addition of a modest solar array or other supplemental power source. The focus is on emergency communications.

In its current form it is built using the Linksys WRT54G/GL/GS wireless routers and operates on channels 1-6 of the 2.4GHz ISM band, which overlaps with the upper portion of the 13cm amateur radio band. Other platforms and bands are in development at this time. Next will be Ubiquiti equipment with others supported as development resources permit.

OLSR is used for auto linking of the mesh node radios.

OpenWRT firmware tools are used for firmware development.

Broadband-Hamnet™ is currently being designed, developed and deployed as an amateur radio broadband communications system. It originated in Austin, Texas but has spread all across the USA and many other countries around the world.

This system could provide the following services:

  • VoIP/SIP Phone service (possibly Skype, FaceTime, and iChat)
  • Internet Relay Chat (IRC)
  • Email
  • Windows File Sharing (SMB/CIFS by both URL and UNC)
  • Web Pages (HTTP, both intranet and internet)
  • File Transfers (FTP)
  • IP Cameras
  • Local Wifi (by attaching an access point to the mesh node)
  • Local 3G/4G Cell Phone Service (by attaching a 3G/4G extender to the mesh node)
  • Remote Desktop/VNC (for remote control of workstations and servers)
  • And anything else you can do with an IP network

This will require many mesh nodes, wherever we can get them up high (antenna towers, tops of tall buildings, water towers, etc.) above trees. There will be nodes that act as internet gateways, extenders/forwarders, and enduser access.

Locations where it could be used in an emergency:

  • County EOC
  • Fire/EMS Houses
  • Hospitals
  • Red Cross Building
  • Shelter Locations
  • Schools (if not already shelter locations)
  • Airport
  • National Guard Barracks

A Hypothetical Mesh Topology

The following image shows a simple mesh design. Anything that can be done with an IP network or the internet can be done over the mesh, assuming it doesn't violate Part 97 of the FCC Rules. This could also include any other IP devices, wired or Wifi.
