HSMM Mesh Network in Texas

In Collin County Texas a groups of hams have been making good use of HSMM technologies to update their Amateur Radio Communications Health-care Emergency Services (ARCHES). This was traditionally setup of two meter/ 70cm voice and packet radios at 9 Austin, Texas area hospitals.

The setup provides key patient data to the City of Austin Emergency Operations Center, during significant incidents, even if normal communications are unavailable. It's highly successful. During every activation, patient data and other traffic passed more quickly and accurately than all other techniques tested during the activations.

The ARCHES program has been so successful, we have been asked to expand the system to ~ 40 additional area hospitals and clinics in central Texas.

Due to the existing significant number of packet collisions using traditional packet radio with just 9 nodes, they are migrating to HSMM.

With 40 or more packet stations in the area, passing packet data could slow to a crawl due to packet collisions.

The stations could only transfer data at 1200 baud, at best. Attempts at using 9600 baud showed that common radios do not pass 9600 baud data well. They distort the data so badly, that many resends are needed to get data through.The effective data rate seldom exceeds 1200 baud.

The HSMM proof of concept was demonstrated least year by AD5OO, NG5V, and KD5MFW who achieved a 10 mile point to point link across downtown Austin, Texas using only 35mw.

The Austin HSMM SIG has incorporated Optimum Link State Routing (OLSR) into custom firmware to provide automatic linking of radios that will be placed on Water Towers throughout Collin County Texas.

HSMM VOIP Network in Spain

There is an interesting HSMM/ Asterisk VOIP network in Spain:

Alex EA5HJX, Andres EA5HIQ, Pepe EA5SW, Paco EB5HTC, Javier EB5BXA, Boletin EA5SW, Paco EB5EA, Sergio EA5HFB, Ernesto EB5JDY and several other hams are researching new technologies and telecommunication systems.

Can you explain are in street language, What is Intended and this project will bring to ham radio and its benefits?

So we can all understand, a HSMM network is just one of many highway lanes that can move large amounts of data at high speed. What would be technologically wireless broadband network of high capacity in her ability to integrate all technologies: RF, VoIP, multimedia, data ....

What are the Objectives of the Project HSMMN?

To promote knowledge and new technologies to the general public: The HSMM project has not only a technical aspect but also a social aspect, with aims to bring new technologies and their application in the real world to the public with expertise or not. Disseminating knowledge and new technologies to the general public: The project has HSMMN Not Only But Also to Technical aspect of social aspect, with aims to bring new technologies and their application in the real world to the public with expertise or without them.

We intend that anyone interested can collaborate, learn and practice the knowledge acquired. Anyone interested can collaborate, learn and practice the acquired knowledge. To this end, talks and workshops are planned in various radio clubs and associations interested in the project.

Creation of a research group developing new technologies to the world of amateur radio: This project not only aims to develop the network, which is the chief end of it, but to bring together people interested in researching and learning about new technologies to help amateur radio operators and emergency services communications.

Unifcar technologies: using computer systems and hardware elements to create an IP data highway you can travel by all types of information: audio, video, telemetry, APRS, etc ...

Collecting, processing and sending information through a variety of different technologies such as for sending APRS weather information (winds, rainfall, air pressure, barometric pressure, etc)

Ability to provide automated voice announcements from a centralized control room radio repeaters as required. Capacity to Provide automatic voice announcements from a centralized control room radio repeaters as required.

Creating an information service of communications systems available by region, by using a geographic number to gain access from the fixed, mobile and IP (VoIP).

Integration of other communication networks: IRLP, DSTAR, WIRES-II, E-QSO, etc.

Interconnection of repeaters using wireless technologies: Wireless, WiMAX. Each repeater could put a computer capable of processing all the telephony and transform it into Voip (voice over IP) that is transported through the network to reach another repeater HSMMN and is decoded by joining together all repeaters creating a mesh. Each repeater Could put a computer capable of processing all the telephony and transform it into VoIP (Voice over IP). That Is Transported through the HSMM network Reaches Another repeater network and is decoded by joining together all repeaters creating a mesh.

The whole process will be use Free Software.


Entities in the world of emergencies communications in Spain have shown interest in this project as an additional operational tool to consider for future medium to long term. Access from the PSTN will be in collaboration with guifi.net. This is an area open, free and neutral telecommunications network built through a peer to peer agreement where everyone can join the network

It looks like a nice mix of HSMM, Asterisk SIP and app_rpt technologies.

Alex Casanova EA5HJX, writes that he is working to develop a box that is a router (IP), and Asterisk (VoIP) and gateway with radio (analog and digital radio). Maybe this box can help in disaster like Haiti. Around the HSMMN´s Project we are investigate to integrate Asterisk VoIP with analog or digital radios.
