Marc:

Alix, Microtik, etc are examples of the "compatible" hardware I was referring to. I have a couple of Microtik boards myself running Ubiquiti SRs. However, BBHN has not been ported to any of these as yet. And they considerably more expensive. You can make a "compatible" node on them of course but it isnt BBHN.

Bob,

John Hansen tested both the radio's that you posted and presented his findings at a previous DCC.

You are correct that these two radio's can be used with modified linksys gear. But why do that when ALIX type boards from PC concepts are available? Soekris boards will accept those radio cards, as will Mikrotik routerboards.

Enough of this.

The point about the UDR56K that was  presented at DCC is that the 56K barrier may not exist. The presentation at DCC is not included in the proceedings, unfortunately, so unless you were in attendance, you may not find what was discussed on the interweb. You may need to communicate directly with the UDR56k team to learn just what are the capabilities of their radio as the published information is somewhat lacking.

Alternatively, the conference was filmed and I believe the video is available on amateurtelevision website.

WIFI = IEEE 802.11a/b/g/n MAC, PHY, waveform.

While a 56 kbps radio is of general interest to most anyone playing with digital modes it is not very closely related to "BroadbandHamnet", being simply a "pretty quick packet radio". You can run TCP/IP over any bidirectional serial link. You can also mesh pretty much anything that involves TCP/IP with the right routers. However 56kbps is no where near the data rate required by "high speed multimedia". You would be hard pressed to do one channel of VoIP over a solid 56k link.

Im not belittling it - 56k packet has been a long time coming and it has a well defined place in the world of Amateur Radio. But it is part of a different "food chain" so to speak.

The radios I posted are 1 Mbps to 54 Mbps 802.11b/g mini-PCI radios that produce several WIFI channels on 70 cm. They can be directly interfaced to and supported by OpenWRT/OLSR software and WIFI radio drivers on certain hardware (H/W that is equipped with mini-PCI slots or over USB-to-mini-PCI adaptors) for which these S/W have been ported.

The Linksys routers currently supported by BBHN can be adapted to use these radios by exposing the USB ports currently present on the Broadcomm chip, adding a power injector and a USB-to-miniPCI adaptor, and loading the USB driver packages for OpenWRT. Certain compatible hardware that may be supported later can use the cards directly.

The 56kbps radio is a radio for a different technical domain, and is generally governed by different sections of Part 97 rules. For example, Radio Amateur use of spread spectrum such as WIFI is currently limited to 10 watts PEP. A packet radio can run the full legal limit. But the bandwidth they can occupy is significantly different.

Ciao a tutti.

Sto cercando di mettere insieme un gruppo di OM qui nei pressi di Scandicci (Firenze) per provare a vedere come potrebbe funzionare una hsmm-mesh fissa non mobile in questa zona "collinare".

Per adesso ho 2 WRT54GL equipaggiati con l'ultima versione della Broadband-Hamnet v1 ed 1 Raspberry-pi con l'ultima HSMM-PI (veramente una grande svolta sia per l'hardware che per il software!!!) che interagiscono alla grande, ma per ora solo in casa mia! E solo nel fine settimana o dopo le 22 e fino a quando non mi accascio sulla tastiera!!  :-)

Per info su HSMM-PI vedi http://hsmmpi.wordpress.com/... molto interessante e poi Scott è molto disponibile anche per migliorare il suo lavoro ed eventualmente integrarlo con altri hardware.

Siccome i Linksys non si trovano con tutta questa facilità... pur essendo macchine molto potenti e versatili che diranno la loro ancora per molto tempo, ma volendo provare ad andare a 5GHz, sto cercando di creare il setup che permetta di integrare dei device della Ubiquiti (economiche e... di tutti i "tagli" sia di soldi che di configurazioni) nella HSMM-MESH inmaniera trasparente, come ha fatto Scott per HSMM-PI.

Qui in Toscana abbiamo una bella realtà fatta di esperienza e persone in gamba (v. informazioni su http://www.wifisiena.it/) che hanno scelto però materiale Mikrotik e protocollo OSPF, incompatibile con la rete HSMM-MESH. Queste però sono scelte legate a due diverse tipologie di rete (ad-hoc vs p2p). Comunque mi stanno aiutando in quelle "finezze" del wifi-networking che ancora non maneggio come si deve.

Chissà che un giorno non si possano unire le reti HSMM-MESH che sono nate, stanno nascendo o nasceranno in Italia... lo spero proprio!

Ci sono altre esperienze da raccontare?

Io resto QRV.

It would be helpful if the BBHN Package Manager listed the memory requirements for each package in the list of available packages. It would also be helpful if the available memory for installing packages were also shown on that page.To carry that idea still farther, it would be good if packages that will not fit are greyed out.

http://nwdigitalradio.com/ is making a 70cm digital radio, coming soon.

Has anyone looked into the android app listed in the subject?

Info can be found here.  Might this be an easy way to get voice connectivity over a mesh using smartphones connected to the mesh through WAPs vs going the VOIP route?

The 79xx's are a whole different ballpark to be playing in. You have to load the configurations via TFTPboot.

As for the Chrome browser, in my videos I am using IE9. So if it works there, it will work in any browser (I switch between Firefox and IE9).

Send me an e-mail and I'll help get you squared away and then post the solution here.

We live in the woods of SE-GA, USA & no one near here is interested.  Perhaps in the future, if we get 
some younger Statesboro-area Ham Club members, we can try this again here.

Two Linksys WRT54G3G-ST devices with wall warts, original antennas, plus one mag mount antenna 
(car top or file cabinet top or whatever for better range).

They are loaded with the newest release OS.

Our two units communicate with each other fine so I know they are working 100%.

Asking $57. for the pair w/mag mount antenna, shipped.
