<p class="MsoNormal">I'm happy, what's wrong with the rest of you <grin><br>
<br>
A simple question has now branched in three directions; number of igates, server load, and paths so lets consider each of them individually, because they should not be grouped together.<br>
<br>
Igates.<br>
I think you need to ask each operator why <b>they</b> thought it was necessary to add their gateway to the network. Is an extra gateway or two such really an issue, in the absence of a truly wide area system, when greater Sydney covers such a huge area with
diverse geographic features such as mountains, floodplain, coastal strip, cities with tall buildings, etc? Mandating for maximum numbers of igates can only ever be a recommendation which is not enforceable, but even if such a scheme could be implemented, who
would determine which stations would be granted the right to operate an igate and on what basis would that station be chosen over others. I believe that such decisions are best left to the amateurs in a given area to decide their needs, rather than a clueless
committee with no idea of the "local" situation. The people at the coal face know best their local requirements.
<br>
<br>
APRS-IS.<br>
Scott Evans, who hosts a T2 server, has already told us that server load is a non-issue, with the proviso that rotate servers are used.
<br>
<br>
Paths.<br>
Australia has chosen the same path recommendations as most of the rest of the world, and uses the WIDEn-N paradigm which was devised by Stephen Smith, WA8LMF, as a means of improving channel carrying capacity. The original RELAY and WIDE system caused horrendous
duplication of digied packets. Stephen lives near Los Angeles which has the greatest aprs density of any place on earth. The WIDEn-N paradigm limits the uncontrolled spread of packets that existed with the old scheme and, when properly implemented gives the
best possible utilisation of a given aprs channel. I recommend you to this page by Stephen Smith for an explanation ...
<a href="http://wa8lmf.net/DigiPaths/">http://wa8lmf.net/DigiPaths/</a><br>
<br>
The recommended vhf paths for mobiles in Oz is WIDE1-1, WIDE2-1 which gives two hops. (
<a href="http://www.aprs.net.au/vhf/national-2m-aprs-network">http://www.aprs.net.au/vhf/national-2m-aprs-network</a>). For more remote areas, WIDE1-1, WIDE2-2 which gives three hops, is a suggested alternative. Combined with intelligent digi software that
detects duplicated packets, the system works quite well, given that all digis are responding to the same aliases. To further control the spread of packets, and to put the brakes on operators who want to try to use unrealistic paths, intelligent digi software
such as UIDigi can truncate long path requests. Paths of WIDE3-3, WIDE4-4, WIDE5-5, WIDE6-6 and WIDE7-7 are repeated by a smart digi but in a way that enforces "the LAST hop" for such packets. The TAPR aprs mailing list is a good source of discussion of such
things as paths and packet duplication and Google can be your friend.<br>

<pre>Guys and Gals,<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>Take a look at recommended paths and you'll see why multiple digis are <o:p></o:p></pre>
<pre>retransmitting a station.<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>A mobile with WIDE1-1 WIDE2-1 will have two hops. Most, if not all, <o:p></o:p></pre>
<pre>digis respond to WIDE1-1, so most digis will retransmit a WIDE1-1 <o:p></o:p></pre>
<pre>packet for another hop (to any other digis that hears it) and that <o:p></o:p></pre>
<pre>(those) digis will use the WIDE2-1 part of the path. A path of WIDE1-1 <o:p></o:p></pre>
<pre>WIDE2-2 will have three hops, extending the spread to another ring of <o:p></o:p></pre>
<pre>digis and potentially more igates.<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>The reason for the closest igate not always being the one that appears <o:p></o:p></pre>
<pre>on aprs.fi (et al) is that the nearest igate might be clobbered by <o:p></o:p></pre>
<pre>another station that is stronger than the local digi - think FM <o:p></o:p></pre>
<pre>capture effect - OR the received packet might be mangled in some way <o:p></o:p></pre>
<pre>through collisions, and "lost", whilst a distant igate will receive a <o:p></o:p></pre>
<pre>valid signal via its local digi and deal with it appropriately.<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>APRS is a bit (a lot!) of a free-for-all for channel access compared <o:p></o:p></pre>
<pre>with connected mode packet where stations hold back transmitting, as <o:p></o:p></pre>
<pre>defined by the channel access parameters of DWAIT, Slottime and <o:p></o:p></pre>
<pre>Ppersistence.<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>A situation I see reasonably often is, I can be gating a station <o:p></o:p></pre>
<pre>that's using vk2rcn-1 just fine, sending numerous packets to aprs-is <o:p></o:p></pre>
<pre>and then, out of the blue a packet will go via a couple more digis to <o:p></o:p></pre>
<pre>be gated by a station in Tamworth. I'm in Kempsey. Obviously my rx has <o:p></o:p></pre>
<pre>been clobbered by vk2rdo-3, vk2rmy-1 or vk2jub-3 and I lost the packet.<o:p></o:p></pre>
