    This webinar is an online version of a 802.11 wireless networking training seminar conducted by Kip Moravec AE5IB and Rusty Haddock AE5AE in the North Texas area at Lucas, TX. Seminar will include an introduction to wireless networking and the HSMM-MESH(tm) software developed for use on Linksys WRT54GL wireless router. Instructions for replacing the Linksys firmware with the new firmware will be given.

    HSMM-MESH(tm) 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.

    SPECIAL NOTE FOR NORTH TEXAS HAMS:
    The seminar will be conducted at the Lucas Fire Department training room, 165 Country Club Rd, Lucas, TX. Doors will open at 8:00am for set up. Those hams wishing to attend the seminar in person should contact Kip Moravec AE5IB at kip@kdream.com. Seating is limited.

    Default Need mor info.

    The article could use a bit more information? What is the application for this? Use it to connect to other routers or computers or? I hate articles that have links that want you to go here or go there for more info. If you can't be bothered to supply at least the basic information then why bother at all?

    I'll second the request for a bit more info - for those of us that've never heard of it before - this sounds like it could be useful - a ham(?) networking setup - higher speed, perhaps easier to use than the packet network (that appears to be disintegrating). Could be an important e-comm tool - ?

    Here we will try to enlighten and educate you all about the High Speed Multimedia MESH network HSMM-MESH™ currently being designed, developed and deployed as an amateur radio broadband communications system. It is being used in and around Austin, and Plano Texas, as well as other sites.

    Glenn KD5MFW, David AD5OO, Bob WB5AOH and Rick NG5V are the gents spearheading the efforts, while yours truly, Jim K5KTF is trying to get this site up and going to provide information about the project. There is a distributed development community with significant activity in the Dallas/Plano area and interest growing elsewhere.

    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 WRT54GL wireless router 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 may be supported as development resources permit.

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

    OpenWRT firmware tools are used for firmware development.

    Please check back often as I will be building this as spare time (eg in between paying work) allows.

    We appreciate your interest, but please understand that it may take a while to respond to your questions.

    Thanks and 73

    In order to gain benefit from this system you must be fluent in TCP/IP networking or be a highly motivated self-starter who can independently acquire that fluency. At this stage there are relatively few developers and users, and they are already stretched thin with their current contributions. While we have made the system as easy to use as possible, it can still be a complex system and we cannot offer any basic network training. As our user and developer base grows we may collectively be able to offer such support but at this time you are responsible for your own education in the fundamentals of computer networking.



    HSMM-MESH™ is not a fully mature, time tested, finished product. However, its basic functionality is proven and it is quite useful in its current state. It provides a network infrastructure upon which numerous applications can be built. This project is in its infancy and requires contributions from its users and developers before it will be suitable for a wider audience. If you have a specific application in mind, hop on board and help us grow the capabilities of the mesh.



    HSMM-MESH™ is not a one-size-fits-all solution. It may or may not be suitable for your application. You will be better served by changing your application to fit the mesh than the other way around. Using a mesh node is relatively easy. Setting up its internal structure and services to create the mesh is not easy, but it is very easy to break if not done correctly. While it is essential to have an understanding of general networking principles to use the mesh effectively, the mesh is not a conventional network. You will have to learn some new ways of thinking about networking. I strongly recommend reading the HSMM-MESH Design Philosophy article for an overview of how the system is designed.



    All that being said, this is a new way to HAVE FUN with ham radio! For $60 you will not be able to find a more capable radio than that contained in a WRT54G. If you have grown weary of the colossally slow pace of digital communications with HF and VHF radio, give HSMM-MESH™ a try!
    Sheesh. Is it really that hard to follow a link?

    HSMM-MESH Design Philosophy

    HSMM-MESH™ is not just any mesh network, it is a specific mesh network designed to meet certain goals and operate in a specific fashion. It will not meet the needs of everyone and is not suitable for every purpose. However, it is quite flexible and should provide a valuable and extensible service for its users.

    HSMM-MESH™ is meant to be the high speed digital progression of existing Amateur Radio practices and used only by licensed Amateur Radio operators. Emergency communication is very much a driving factor in the architecture of the network. To that end, it aims to be the network of choice when the need arises to quickly create a network where none exists, and to be the easiest to set up and most capable while running. It also is suitable for permanent installation, providing high speed digital Amateur Radio communications over a region with line-of-sight RF access to at least one of the participating nodes.

    So with that in mind, here are some of the features that define HSMM-MESH™:

    •All networks called HSMM-MESH are interoperable
    ◦A node configured to participate in one region can be moved to another region and continue to operate, without reconfiguration, with full access to the network
    ◦Experimentation is encouraged, but if a network is set up in which a standard node would not have full network access, its SSID must be changed to something other than HSMM-MESH to indicate that it is an alternate network
    •The OLSR protocol is used to route traffic between all nodes that can see at least one other node, thereby forming a mesh network and allowing all nodes to communicate with each other if a path exists between them
    •The WiFi interface operates in Ad-Hoc mode, otherwise peer-to-peer communication would not be possible
    •A node should require a minimum amount of configuration before becoming fully operational
    ◦General participation in the mesh should not require any centralized administration
    ◦No allocation of resources or manual assignment of addresses or subnets is necessary
    ◦exceptions for specific cases include but are not limited to:
    ■inter-mesh or inter-region bridges
    ■any services which can cause network conflicts
    •Access to the mesh is available only from a mesh node, not directly to client devices
    •Equipment on the LAN of a mesh node should not require any special software or setup to gain full access to the mesh
    ◦The supplied DHCP parameters (or their static equivalent) should be sufficient for full network connectivity
    ◦This does not pertain to specific applications, only to general network access
    •It is a fully self-sufficient network and does not require any other infrastructure or resources to be in place for its participating nodes to be able to communicate with each other
    •DNS is an integral part of the system - you should never have to know the IP address of any mesh node, using the hostname is sufficient to initiate a connection
    Additionally, there are certain things that HSMM-MESH™ is not:

    •it is NOT a replacement for your home internet connection
    ◦being an Amateur Radio network, it can only carry traffic that is allowed under FCC Part 97 rules
    ◦several types of internet traffic violate these rules
    •also, it is NOT a replacement for your home internet connection
    •finally, it is N O T a replacement for your home internet connection
    •and by the way, it most certainly CANNOT be used in any way with your business network
    I hope I have made myself clear. If the internet traffic contains data types that are already being used over ham radio such as Echolink or findu.com, that is perfectly acceptable. I am not a lawyer so I will not attempt to enumerate all the types of data that are or are not permissible under Part 97. It is your responsibility to comply with the terms of your license. If you question the permissibility of your internet traffic, it is probably best to not use it. This is the kind of traffic that your home internet connection is better suited for. You probably have Part 15 WiFi access to the internet. Use that instead.

    Section 97.113.a.5 states: No amateur station shall transmit communications, on a regular basis, which could reasonably be furnished alternatively through other radio services.

    This is what Part 15 is for: your day-to-day non-ham internet activity. HSMM-MESH™ on the other hand is, as are all ham radio activites, a service for the purpose of self-training, intercommunication and technical investigations carried out by amateurs, that is, duly authorized persons interested in radio technique solely with a personal aim and without pecuniary interest.

    Default Check it out.

    The ARRL had a High Speed Multimedia group in 2001. So the concept is not new. The HSMM-MESH project has just uses low cost routers and big antennas. A node costs less than any other HAM Radio.

    I have gotten 5 and 10 mile links easily with clear line of sight using off the shelf WRT54G routers and external antennas. We load mesh software to make configuration much easier.

    We send video and photographs that would be impossible with packet.

    Check out the webinar and see if it is something you would be interested in.

    For $60 you will not be able to find a more capable radio
    than that contained in a WRT54G
    For those who want to experiment,
    I'd suggest checking your local thrift stores.
    I find them regularly for around $5-10 working just fine.

    HSMMs caught my attention a few months ago. Being a computer (and now radio also) geek I found them to be very interesting. I recently picked up Ubiquity Networks NanoStation (http://www.ubnt.com/nanostationloco) for a small HSMM project. So far I have been very happy with it, better yet as someone who has limited space HSMMs can be fun as the antennas are not massive. Once in place I was hoping to hook all of this up to my home-brew server and test the range from the 7th story!

    A fun way to experiment with the microwave bands using off the shelf equipment....

    Sounds very interesting. I already have five WRT54G routers. I got some of them under $10 at thrift stores as someone already mentioned. I usually run Tomato firmware on mine for regular Internet use, since Tomato is so simple to use. Too bad I already have other commitments today.
