Pak do bude mit nominalni dosah 1.9km. Nebo muzes pouzit normalni Ronju s nominalnim dosahem 1.3km a zalohovat ji mikrovlnou. Bude to castejc vypadavat ale uzivatelum to vadit nebude protoze pri vypadku pojedou pres mikrovlnu. Obyc Metropolis se tim prodlouzi dosah z nominalnich 1.3km na zalohovanych 1.9km.

Thus I feel I personally don't intend to go extraordinary lengths. I will just read my government regulation and believe that this regulation is strict enought to protect people from any damage risk. What I have heard is that these regulations are done so that the case where temporary damage (not permanent) on the retina is observable by an expert physician is taken and the value is divided by ten. BTW I am almost sure Sun wouldn't pass these regulations. > strongly that we must always be transmitting much lower than a certain well > defined value, and state the power output in any and all or our We must transmit as low as to be sure noone will be posed to a mere risk of temporary retinal damage even under worst case condition and deliberate trying to damage his eyes (intentional staring into the beam from immediate distance etc.) > > Note, > > (reading Dr. Jim Alman's article on Eye safety and Wireless OPtical Networks in this pdf found here: > > http://www.airfiber.com/tech/Laser%20Eye%20Safety.pdf Thanks, added to web links > The collimated light beam entering the eye in this retinal-hazard wavelength > region is then concentrated by a factor of 100,000 times when it strikes the > retina.

They can reach the human retina in a millisecond and can therefore blind anyone looking into that beam, i.e. Alignment by eyeballing it, is therefore never as safe as you claim, unless VERY, VERY low power is assumed (under 10 mW) and links are carefully maintained not to stray and the beam width is tightly controlled and hence the maximum distance or usable range of such links works fine for some but is very short! > > > simple 5-10mw, i can burn my eyes. but. with 300mw can i go further, > > let's say. 2-3km?... 300mw..:) > > re: the statement: > > >With 300mw you can go I guess 10-20km. > > You will only achieve 10-20km in the vacuum of space! Since terrestrial FSO live in real world environments i.e. fog, sleet, rain, snow or strong sunlight) the maximum realistic ranges will barely get beyond 2km and remain usable. The more important issue is that at such higher (say 50-300mW) power outputs we will also blind anyone looking directly into the beam even if they are not using binoculars. Contravening basic health + safety laser rules is not a good idea unless we are going to shoot down birds or we like to blind our link partner and face lawyers and links being shut down plus the inevitable lawsuits for blinding another! > > Such so called *acceptable* power IR laser beams at wavelengths greater than 1400 nm are fortunately absorbed by the human cornea and lens, and do not focus onto the retina. Because of these basic biophysical properties of the human eye, wavelengths > 1400 nm and up to 1550 nm are sensibly allowed by standards bodies around the world as approximately 50 times greater intensities in such IEC/ISO rules than wavelengths near 600-800 nm. > > This fact alone can be exploited by us all by carefully specifying a wavelength in the 1550 nm range, where the factor of fifty additional laser power one can launch through the equipment's loupe lens allows the safer FSO system to propagate over much longer distances and/or support significantly higher data rates. IS this not a plan to improve the design and try for E100 or 100 Mb/s bidirectional at 2km?

One particular msg I want to comment on is should we add eye safety as an issue? IR laser diodes should be chosen not just for the greatest reliabilty and longest distance link margins in the future but include eye safety in the ongoing development of Ronja today and in the near future. The topics I have been tracking so far by reading posts from ronja@lists.pointless.net are done under extreme duress while my eyes heal slowly after being under the laser knife so to speak, So forgive the ones I may have missed as I can read only large fonts so far as my retinas have detached and I cannot translate so easily as you do from the Czech language to English, as yet ! Am working on that though! LOL First for some readers, The Physics of Free Space Optical (FSO) needs to be understood and this link helped me and others here a lot:. http://www.airfiber.com/tech/Physics%20of%20Free-space%20Optics.pdf Aa far as I can tell, the following short course is the only one in Europe. It is taught by Prof. Tony Boucouvalas BSc (Hons), MSc, DIC, PhD, CEng, FIEE, FIEEE, FRSA; Professor in Multimedia Communications in the School of Design, Engineering & Computing at Bournemouth University and a quote from his outline course notes which are very illuminating from here is not out of order at Ronja's losts.pointless.net: http://dec.bournemouth.ac.uk/ttc/html/short_course__optical_wireless.html Free Space as a transmission channel. LEDs and Lasers as sources. Beamforming of the optical radiation. Photodiodes and receivers. Ambient noise. Encoding for optical wireless. Low cost optical link design and limitations. UART and SDLC based links. Error detection and probability of undetected errors. IRDA user model optical wireless links. Eye Safety Issues. IRDA IrLAP Link layer Protocol Performance. High speed links. Real time traffic over optical wireless issues. IEEE 803.11 optical wireless user model. Market and technology trends. Note the eye safety issues. So many of these topics need seperate posts. So far the Ronja posts have been ranging from individuals who are or have already completed the existing design that is on the specific website. On the more general heading of: "what laser power output do we really want to transmit?" or "how do we get faster and further range beyond that achieved in Prague?" By using several optical component catalogues and picking one (e.g. hpwt-bd00 for example) we all see we can have less than 12mw or more than 12 mw output power. Yet Model RLT6850G, emits at 685nm, and at a higher 50mw launch power so that must be good of not much better surely? Yet others argue that this part costs around US$40 each and they would rather than use a laser pointer chip that costs under $2! This begs the question. What other brand/ manufacturer's part number / launch power output has anyone in the group looked at and tested to destruction or more pertinently, are any IR laser diode parts at 685 nm ideal for any range, at 50mw even at existing 200 meters? Should we not all consider changes like these being made as *future development* and not a "refinement" as far more than a mere change of a part is at stake. The future of Ronja ideally lies in longer range faster versions, and we all could simply bow to superior knowledge at the current design and address basic issues realistically. That issue to me is: how do we get from 10 Mb/s AUI abled Ronja 10M at over 200 meters range to one day achieve 10/100 Base T Cat 5 or Cat 6 cabling at up to 10/100/1000mb/s at 2000m and above? Are we not asking the following questiond: "exactly what IR frequency do we agree is best for 10 Mb/s?" We can all choose various IR frequencies or HP parts for the best reliability, greatest possible range and most importantly to some, absolute affordability, but in order for some to want to build it at all we just need a baseline. When or if we ever jump from 10 to 100 mb/s to 1000 Mb/s bidirectional data rates and change from AUI to RJ45 or from Cat 5 to Cat 6 cables may well be irrelevant! Assuming though, that some of us are interested on continually using E10 and allow only current proven AUI connections vs the future 10/100/100 PCI based RJ 45 style Cat 5 or Cat 6 cables to attach to Ronja 10M pr future models, who wants to begin a design that will be supporting 10/100/1000 Mb/s using RJ45 Cat 5 or Cat6 Ethernet cable? PCI NIC cards exist everwhere in abundance. AUI NIC cards are less visible but are already deep discounted at under US$10. US $15 buys one 10/100 PCI cards and around US$50-75 buys a branded Intel Gigabit 64 bit PCI card with 10/100/100 Mb/s support! FSO (free space optical) communications links are here now from 13 vendors that do just that at 4km. Some being even faster at 2.5 Gb/s but clearly they cost an order of magnitude or two more than Ronja. We are not commercially motivated though and nor is the market only telcos! ONLY by running truly eye safe in the near- or far- infra-red end of the spectrum can we however truly succeed where others fail. While two or more Ronja 10M units around a town end up costing under US$50 to $100 total in parts cost alone to build (i.e. US$200 per pair of links) the parts cost is a big issue. What if we relax that to $300 for two? Underlying these costs to buy parts versus the cost to make a fully compliant commercial product issues that remain are we need some basic idea of relaxing the requirements. Are we finding a justifiable reason to need the 99.999% reliable link subsystems of the commercial priduct offerings to Telcos at all? We hobbiests can live with far less, say 98% uptime or even less . somewhat equivalent to cable pr ADSL broadband access from cable companies or telcos for a home or business. So how do we actually achieve greater RAS (reliability, availability and serviceability) in Ronja 10M without paying the price for good parts. The same goes for future Ronjas at 100 Mb/s or 1000 Mb/s at even greater range beyond 200 meters approaching 2000 meters. I would like to offer a little more background reading and to fill in some of the obvious research detail. Offering this to the group on a one on one is not as good as the issue of all of us helping one another resolve this. An eye-safety issue seemingly has been forgotten or have I missed something already discussed before in Czech or English? So I offer links here to that one so it can be put to bed once and for all. I continually wonder just how we are to avoid future trouble with any of the many countries'hidden safety and telecom regulators. One Answer I can almost hear screaming back at me from the group is: Surely if we just ignore the bastards, we do not have to worry about eye safety at all! Yes, perhaps we could for a while is my answer, but today we have a couple of pairs of links in Prague and a few elsewhere and that may well be true today but do we not do so at our own peril when someone complains of severe eye damage in a different locale? In some countries eye safety regulators are entirely invisible, yet the ISO/IEC exists from 1947 onward to protect the global public (See below references to various optical standards and online docs in pdf format pertaining to IR laser links and eye safety.) The url of ISO as an organisation is to be found here but O challenge anyone to try finding out what we want and pay for the docs! Grrrr! http://www.iso.ch ISO standards offer practical solutions to many of the problems of developing and developed countries too. Developing countries and countries making the transition from a centralized to a market economy make up some three quarters of ISO's membership. For them, ISO standards are an important source of technological know-how for developing their economy and raising their capability to export and compete on global markets ISO/IEC standards thus pertain to the highest possible safety factors in any small or large scale deployment of FSO links like we envisage. Even a standard exists for microave radiation of kitchen ovens and just what a wireless Wi-Fi (IEEE 802.11x) microwave link SHOULD be aloowed by transmitting under preset conditions and known power levels. This is not just another silly world domination or government regulation to worry manufacturers! It affects the safety of all those human beings who are in the line of sight of a non eye safe laser beam in any country and thus affects us all, so that designers and any implementers, wherever they are loacted need to care about installation. Just to achieve the *greatest distance possible at the very least cost* is therefore not the only problem we have to resolve. Note that there are clearly MANY OTHER well-documented CDRH and ISO/IEC safety rules (see below) that apply here and not just become rule of thumb or *acceptable limits*. We should assure all our users that this is experimental and even if asked by innocent lay people who just live around us, especially those who are going to be directly in the laser beams path that we are ALL of us going to go to extraordinary lengths to protect the public and ourselves! Thus I feel strongly that we must always be transmitting much lower than a certain well defined value, and state the power output in any and all or our implementations and future RONJA designs. Note, (reading Dr. Jim Alman's article on Eye safety and Wireless OPtical Networks in this pdf found here: http://www.airfiber.com/tech/Laser%20Eye%20Safety.pdf and another pdf found here: http://www.freespaceoptic.com/WhitePapers/wavelength_selection.pdf Plus raw text from one other vendor's site, FSONA Corp, in Canada their literature can explain the topic: http://www.fsona.com/product.php?sec=safety Briefly, there are eye-safety limits vary with any IR wavelength. The free space optical (FSO) wireless hardware currently on the market (and RONJA is one of those in continual development), they all can be classified into three broad categories ? systems that operate at a wavelength around 600nm to others around 800 nm and a third, those that operate above 1400 nm and nearer 1550 nm to take advantage of the many DWDM fibre optics in place to achieve 2.5 Gb/s speeds over a 2-4km range. Laser beams at 600-800 nm are near-infrared and therefore invisible, yet like visible wavelengths, the light passes through the human cornea and lens and is focused onto a tiny spot on the back of the retina. As someone with both detached retinas, I know from vivid experience what high powered laser surgery on my eye can do and has truly saved my eyesight in the past few months! This applies for all visible and near-infrared wavelengths in the range of 400 to 1400 nm. The collimated light beam entering the eye in this retinal-hazard wavelength region is then concentrated by a factor of 100,000 times when it strikes the retina. Because the retina has no pain sensors, and the invisible light does not induce a blink reflex, at 600-800 nm the retina could be permanently damaged by some available optical-wireless products (including Ronja 10M if we choose the wrong laser diode!) before the victim is aware that hazardous illumination has occurred. Every choice of diode laser and power output vs beam width MUST therefore be carefully kept well within known eye safety standards or we will DEFINATELY blind someone of not the very guys that assemble or repeatedly align them! In one post it was stated: > If you use infrared, you will burn your eyes ALWAYS unless you use absolutely unusably low powers. Use beam-expanded visible lasers in any case (or 1550nm which is absorbed by eye's lens), but they are very exotic ...... This is very true, except that the question is which infra red. Some of us also strongly challenge the so called *exotic nature* of using *expensive laser diodes* as they are not ALL expensive around 1550nm. In reality they are the 1550 nm selection is very broad and most thoroughly understood by optical engineers and are thus well developed and best categorised as very reliable, plus they are more freely available too discounted plus have great RAS specs and even come in several ranges of low, medium and higher power outputs to suit several free space optical projects like Ronja. The so called *unusable* aspect and the *low power vs higher power* questions need to be seen in terms of three fundamental saefty issues: 1. what do the current eye safety rules say around the world and how do we implement them in each country so we comply? (as some of us are in North America we see a number of CDRH class laser standards from 1m to 3B and up to Class IV lasers to conform to standards, see below but only Class 1m is eye safe.) 2. Adherence to optic industry standards are key too as that is where the R&D effort has been the greatest to date. Ability to operate safely outdoors, in harsh weather environments, and compliant with or certified to: NEBS Level 3, UL 1950, EN 60950 CE mark is another. Automatic tracking and realignment of the beam to counteract building sway building "Self healing" links over alternative FSO links in case of service interruption is yet another. Immunity to bit errors, should a beam block occur, supporting a guaranteed BER of 10 to the power -12 Certified eye safe to Class 1 or Class 1M (as per IEC 60825-1) is vital! Dynamic laser power control for reliable laser operation and extended laser life is one key reliability concern plus a form of Integrated management channel that does not interfere with the payload would be nice! Some vendors in high end equioment costing tens of thousands of dollars even offer Carrier class Element Management System (EMS) for monitoring and management of a broad range of other compliant equipment and 3. availability of very reliable parts from thorourly reputable suppliers at very low cost are merely one concern amongst many others. So the statement in the discussion: >685nm is not much good. 630nm or 650nm is better from the safety point of view. is in need of elaboration as many feel it is totally false economy. Why do we think that 630, 650 is better or worse than 685 nm when the real choice is not between 600 and 800 nm because it is far more dangerous there at those freiquencies than using 1550 nm? Research clearly shows that since the human eye's lens absorbs but does not allow thru lambdas of 1400 - 1550 nm lasers with low power output are safer by definition given certain obvious constraints. Transmitting laser light thru the human cornea and lens with anything below 1400 nm (i.e. around 630, 650, 680, 800 nm and even 1310 nm) is very risky! This means that with any lasers below 1400nm in the infra-red band certain much higher powers i.e 300 mW at 685 nM are dangerous! They can reach the human retina in a millisecond and can therefore blind anyone looking into that beam, i.e. Alignment by eyeballing it, is therefore never as safe as you claim, unless VERY, VERY low power is assumed (under 10 mW) and links are carefully maintained not to stray and the beam width is tightly controlled and hence the maximum distance or usable range of such links works fine for some but is very short! > simple 5-10mw, i can burn my eyes. but. with 300mw can i go further, > let's say. 2-3km?... 300mw..:) re: the statement: >With 300mw you can go I guess 10-20km. You will only achieve 10-20km in the vacuum of space! Since terrestrial FSO live in real world environments i.e. fog, sleet, rain, snow or strong sunlight) the maximum realistic ranges will barely get beyond 2km and remain usable. The more important issue is that at such higher (say 50-300mW) power outputs we will also blind anyone looking directly into the beam even if they are not using binoculars. Contravening basic health + safety laser rules is not a good idea unless we are going to shoot down birds or we like to blind our link partner and face lawyers and links being shut down plus the inevitable lawsuits for blinding another! Such so called *acceptable* power IR laser beams at wavelengths greater than 1400 nm are fortunately absorbed by the human cornea and lens, and do not focus onto the retina. Because of these basic biophysical properties of the human eye, wavelengths > 1400 nm and up to 1550 nm are sensibly allowed by standards bodies around the world as approximately 50 times greater intensities in such IEC/ISO rules than wavelengths near 600-800 nm. This fact alone can be exploited by us all by carefully specifying a wavelength in the 1550 nm range, where the factor of fifty additional laser power one can launch through the equipment's loupe lens allows the safer FSO system to propagate over much longer distances and/or support significantly higher data rates. IS this not a plan to improve the design and try for E100 or 100 Mb/s bidirectional at 2km? Wouldn't we all would like to have a second iteration (or is it third) of Ronja one day rather than be found guilty of blinding someone? Cheers from Canada Added references: Sliney & Wolbarsht, Safety with Lasers and Other Optical Sources, Plenum Press, 1980. Laser eye safety is classified by the International Electrotechnical Commission (IEC), which is the international standards body for all fields of electro-technology. While the IEC is an advisory agency, its guidelines are adopted by the regulatory agencies in most of the world?s countries. A laser transmitter which is safe when viewed by the eye is designated IEC Class 1 or Class 1M. A laser transmitter which is also safe when viewed with a 25 mm binocular is designated IEC Class 1. Laser Safety classifications are summarized in IEC Document 60825-1 and the various Amendments, 1 and 2. In the United States at least, laser eye safety is regulated by the Center for Devices and Radiologic Health (CDRH), a division of the Food and Drug Administration. See URL: http://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfCFR/CFRSearch.cfm?FR=1040.10 The document cited above is dated April 1, 2002. Currently, (in Jan 2003) the CDRH is still operating in an interim period while in the process of adopting the safety classifications of ISO/IEC 60825-1am.2. to be found here: http://www.iso.ch http://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfCFR/CFRSearch.cfm?FR=1040.11 Unfortunately, during this interim period some developers and manufacturers alike are forced to label their products as Class 3B, even though the products are actually eyesafe according to IEC Class 1M. It may take until mid 2003 for the CDRH to complete their standards revision but CDRH issued guidelines to manufacturers in early 2001 about how to minimize the impact to products during this interim period.

It is possible, but I cant tell you if pic16f84 can be used.

"The signal is for maintaining defined DC level of the signal and to key out receiver noise and unwanted signal from being amplified in the limiter." In a previous post I asked if it would be possible to avoid the 1 MHz signal by using a modulated laser pointer as an emitter. I'm not sure about the noise problem but the modulated signal in the laser already has a defined DC component. With a bias current of about 26.5mA (about 1mW of optical power) on the laser diode the DC level on the BPW43 is 500mV aprox. May this solve the DC level issue? NOTE: the test was made from shot distance (2-3 m) with no lenses and the modulating data signal was a 20MHz square provided by an oscillator (no NIC interface yet). I have another question: Why the link integrity pulses can't pass trough the device? (I'm sure you answered this question before, so hopefully a copy-paste may work :) ) If you are interested in more details, just let me know. Your opinion will be very useful.
