I read your last issue on the matter with great interest. I would like to contribute with my experiences: In 1996 I was charged by WHO with putting in place a radio communication system in the DR Congo (then Zaire) for the epidemic surveillance. The initial project funding from the Italian Government was triggered by the outbreak of the epidemic Ebola in Kikwit, DRC. I opted for HF radio with the facility for text and data transmission. Satphones would have been an alternative but the high transmission costs would have rapidly offset the lower investment. The installations began in 1997 and in the mean time some 14 stations placed in ALL provinces form a uniform network. The central point is the WHO country representation office in Kinshasa. 14 more stations are ready to be installed. The Swiss Government has also contributed to the continuation of the project and the Italian Cooperation is still highly engaged. The transmitted data include statistic tables of systematic epidemic surveillance, daily situation reports as well as administrative matters for the field offices. The voice transmission is appreciated for personal human contacts, but experiences show clearly that the transmission of statistics and surveillance reports by voice would be virtually impossible for the volume. Besides, the Pactor transmission offers a high degree of confidentiality, much appreciated for sensible information. The transmission speed varies between 1 and 2 kByte (1000 characters) per minute , depending on propagation conditions. The system has been recognized by a majority of African health ministries and WHO representatives. Only the lack of funds has held back the installation of similar radio networks in other countries. Actually we are testing new terminal software that offers e-mail like user interface, including attachments and automatic routing. Find attached the description of a typical Pactor Radio Station. Don't hesitate to contact me for further information. Beat Streckeisen, Radio Communication Officer OCHA and WHO, Kinshasa. ___________________________________________________________________________ Beat kindly attached the file containing the text posted below ___________________________________________________________________________ WORLD HEALTH ORGANIZATION The Pactor communication system of WHO 4. How does the Pactor Radio system work: The Pactor system is composed of an HF (short wave) radio, commonly called "Phony", to which the Pactor (PTC-2) modem for text and data transmission is connected. Texts are created and received on a small computer that serves as terminal. The attached printer delivers hard copies of received and sent messages. The system can also be used for voice transmission. 5. The transmission in Pactor mode offers the following advantages: * Save and error free transmission of documents in text form. * Opposed to Fax, the addressed Pactor station holds not only a printed document but also a computer file that can be reprinted anytime and may be further processed by any word processor. * The Pactor transmission resists much better to radio interferences and propagation variations. Texts are still transmitted even under so poor conditions that would make voice transmission impossible. * It offers a high degree of confidentiality because considerable costly equipment would be required for the decoding of Pactor transmissions, witch is not accessible to the public. * Pactor transmissions are free of transmission charges. * The UNDP/WHO Pactor network includes a gateway (interface) station to the Internet e-mail system. Every WHO and UNDP pactor field station owns an Internet address and can thus be addressed by any Internet user. 6.

Beat Streckeisen BSEE, Radio Telecommunication Consultant ___________________________________________________________________________ From: Kirsten Myhr To: "'[email protected]'" Subject: RE: Post00323 RE: HEALTH RADIO NETS Date: Tue, 27 Feb 2001 Dear colleagues, My knowledge of radios is limited, but I sent this and a previous list to a friend in Botswana whose company is doing radios, solar-powered, for most of the safari camps and a lot of other institutions needing radio communication. And Botswana is quite a sunny country.... This is what he replied: I have found these (this one and the ones you sent me in the past) very interesting. Some of the advise given is very good (in my opinion) but some is dreadful. For example - one guy is saying use a 20 watt solar panel & another is saying use a 48 watt panel (and this is also for a few lights !!) Here they talk a lot and such small powers would be a joke! (Kirsten's comment: what he means by this is that if people have access to radios, they are also tempted to use them for a chat.) We have to use at least 100 watts for one clinic radio alone - with no lights, high sunshine hours, little overcast etc. There was quite a lot that was incorrect (I assume these people are "health" trained so I do not expect them to be very "technical";). For example - one person said that their 100 watt HF radio draws about 6 amps when transmitting - this is definitely wrong - such a radio needs about 25 amps at a full 100 watts output - it is a VHF radio putting out about 25 watts that will use about 6 amps. One person said they burnt out a radio from a mismatched antenna - yes this will definitely happen if there is a mismatch but it can be avoided altogether if a "wide band" antenna is used - this is matched for all HF frequencies, is relatively inexpensive (P700.00) and very effective. I was quite surprised at the grasp one had on the difference between HF & VHF - but it is not quite as simple as she said - problem with HF is that it is not good short range: unreliable & other problems. HF uses the atmosphere to bounce the radio signal around the globe and is therefore very susceptible to atmospheric conditions - when the "ozone hole" is over us here we have almost no HF communications - a complete failure. One said that HF is more expensive than VHF - this is true of the equipment but normally VHF/UHF must have masts - taking these into account VHF normally costs more - depends on the ranges required and terrain. Also - as someone said - theft is a very real problem worldwide for remote masts - solar panels and batteries are simply irresistible !! Botswana Telecoms now has a couple of guards camping at each mast throughout the country. A South African company is working on cheap tracking devices that will enable the perpetrators to be located - but it often needs a helicopter ! Some solar module manufacturers make panels out of a different colour - green or red instead of the standard grey/black - these different colours make the modules easy to see from the air (helicopter again !) - eg only Government is allowed to use green panels - any panel that is green belongs to the government/para-statal. The coloured panels have the same efficiency as regular ones. Someone was pushing Codan equipment - Codan is good but extremely expensive compared to several other good makes. The make of radio to go for is the one with the best local support, backup and after sales service. All too often a system is installed & proved working only to fail because of lack of local backup once the "maintenance" part of the supply/installation contract is over (if there is a maintenance clause!). One person was saying about using different HF frequencies at different times of the day and setting up a schedule as to what time/what frequencies etc. I have found that this simply does not work for non radio people - they always get it wrong ! There are however quite expensive ( P30 000.00) radios that "talk to each other" (they have to be allocated a range of frequencies to choose from - a "spread" ) until they locate the best possible quality signal/frequency at a particular time. It takes 4 radios about 4 seconds to find the best option at any one time - then they "lock on" and conversation is normal. If anyone is interested in getting in touch with him, please let me know.

Corbett http://www.reliefweb.int/library/wtint/toc.html OBJECTIVE OF THIS COMMUNICATION GUIDELINE Good communications are essential for the effective running of a project. Often the existing telecommunication infrastructure in a project country is not suitable and therefore MSF must set up its own facilities. The objective of this communication guideline is to give a clear overview of all managerial, organisational and technical aspects of setting up and operating a communication system or network. To make the proper choices, you should base them on the overall 'communication policy', as adopted by all MSF-sections in 1998. A country specific more detailed communication policy must be made by the Logistic Co-ordinator and ratified by the CMT (Country Management Team). The target group of this guideline is MSF-Holland field personnel, in particular those who will be ordering, installing or operating communication equipment. Special emphasis is put on the power supply of communication equipment. Failures in power supplies are seen as the main reason of malfunctioning communication equipment. This guideline should be read together with the installation and operating manuals supplied with the specific equipment. After full understanding of this guideline and with the help of the installation and operating guidelines of the specific equipment, logisticians should be able to set up communication systems. For further information on technical adjustments on specialised equipment and configurations not shown in this guideline, please contact the Field Support Unit in Amsterdam. At present all MSF sections have standardised communication equipment and wherever MSF codes are used, they refer to the 'LOGISTIC CATALOGUE' 1st English/French edition or the 'GUIDE OF KITS AND EMERGENCY ITEMS' 99. ____________________________________*______________________________________ 3. THE USE OF VHF, HF, HAND HELD DEVICES, ETC? Paul S. Lalvani, MSH, asks about the potential use of radio connected hand held devices for the management of drug supplies in small rural drug outlets. Do you envisage a solar or fuel cell powered handheld computer running a version of the Commodities Logistics Module [developed for hand held computers] connected by radio to the central warehouse and distribution terminal? Would it work...? Is it affordable...? * replies to Paul Lalvani, c/o: Peter Evans, WHO at: [[email protected]][email protected][/email] ___________________________________________________________________________ From: [[email protected]][email protected][/email] To: [[email protected]][email protected][/email] Subject: Use of radio Date: Tue, 27 Feb 2001 Background: MSH, a non-profit group, working on a grant from the Gates Foundation, is exploring the idea of establishing a franchise of small drug outlets in rural areas, all of whom will be reporting to a central office. Estimate about 300 outlets per country. It is important to receive daily reports from these outlets, which should ideally be a small spreadsheet like file indicating sales, number of customers serviced, new orders, etc. Our vision is to have a handheld device (like a psion or small Compaq hand held computer), which runs a basic spreadsheet, accounting program. The unit will run on batteries, which should last a few months at least. The unit should be able to transmit data on a daily basis (any time during the day or night). It is probably not necessary to download information into this unit, although it is not a bad option to have. I would like to request any ideas the group may have re: the use of VHF, HF, hand held devices, etc. The emphasis is on a simple, low cost, high uptime (not have to rely on tel, electricity) solution. If you have a sense of the cost of the equipment and maintenance costs, that would be useful. Regards Paul S.
