Do you want handheld/laptop devices to be able to<br>> roam through those three buildings?<br>> <br>> And how /many/ devices to you want to get access in there?<br>> <br>> <br>> <br>> If they are just desktops, then personally I would cable them all up to a<br>> switch, and then put a wireless point to point link between the switch and<br>> the main LAN. That way, you minimize the number of wireless devices that<br>> will be competing for airtime, and make your wireless link more efficient.<br>> <br>> <br>> <br>> For a high performance solution with highly flexible and extensive feature<br>> set, I always like to recommend Mikrotik Product: Http://shop.duxtel.com.au<br>> <br>> <br>> <br>> <declaration>we are an Australian distributor of Mikrotik<br>> equipment</declaration><br>> <br>> <br>> <br>> I'm not sure why you mention "no redundancy". what sort of redundancy to<br>> you need? You don't have redundancy with a cable either, but most people<br>> don't worry too much about that! ;-) In any case, many advanced router<br>> systems (Mikrotik included) can support RRP (router redundancy protocol) to<br>> give you automated fail-over in case of one device failing - though I would<br>> say that this is overkill for what you want.<br>> <br>> <br>> <br>> As for 54Mbits, you generally won't get that sort of speed in actual traffic<br>> throughput anyway - more like about 30M for a good close proximity link -<br>> but with equipment supporting dual channel 802.11a (Mikrotik included), you<br>> can get up to 108Mbits air rate.<br>> <br>> <br>> <br>> Furthermore, Mikrotik proprietry routerOS supports dual wireless interface<br>> extensions so that you can run two point to point links in dedicated<br>> transmit/receive and so you can implement a full duplex link with<br>> simultaneous 108Mbit send/receive capability.<br>> <br>> <br>> <br>> But of all you want is just wireless AP coverage for roaming handheld and<br>> laptop support, then any old desktop AP will probably do the job, including<br>> UltraWAP. Again, though, my recommendation would be suitable Mikrotik in an<br>> outdoor case mounted somewhere central to give you improved signal coverage<br>> range.<br>> <br>> <br>> <br>> Cheers!<br>> <br>> Mike.<br>> <br>> <br>> <br>> I'm a network admin for a school, and have 3 rooms that aren't networked.<br>> <br>> Fibre is going to cost a bit, and these rooms won't be used for much, so I<br>> thought a wireless link may do the job.<br>> <br>> Pretty much the 3 rooms are next to each other, and have 3 building<br>> surrounding them, which have network connectivity.<br>> <br>> I would like some redundancy if possible, and as much bandwidth as possible.<br>> <br>> Was thinking an UltraWAP with appropriate antenna on each building, pointing<br>> to the closest networked one.<br>> <br>> But this only provides 54Mbps, and one single link, no redundancy.<br>> <br>> If anyone has any idea's it would be great.<br>> <br>> -------------- next part --------------<br>> An HTML attachment was scrubbed...<br>> URL: http://wireless.org.au/pipermail/melbwireless/attachments/20090114/c63d104c/attachment-0001.html <br>> <br>> ------------------------------<br>> <br>> Message: 3<br>> Date: Wed, 14 Jan 2009 10:41:36 +1100 (EST)<br>> From: Jason Hecker <jhecker@wireless.org.au><br>> Subject: Re: [MLB-WIRELESS] Wireless Links<br>> To: "Shaun Gunston" <shaung@internode.on.net><br>> Cc: melbwireless@wireless.org.au<br>> Message-ID: <4231.203.87.12.85.1231890096.squirrel@wireless.org.au><br>> Content-Type: text/plain;charset=iso-8859-1<br>> <br>> > Pretty much the 3 rooms are next to each other, and have 3 building<br>> > surrounding them, which have network connectivity.<br>> <br>> A cheapie and quick way would be to get six bog standard 802.11G WAPs. I<br>> recently bought an excellent Minitar WAP (with WPA2) for $35 - it's very<br>> reliable, but if you feel nervous about these then buy something a bit<br>> more pricey.<br>> <br>> Along with the APs get some suitable runs of coax and external antennas<br>> (for the distances you are talking a directional may be overkill).<br>> <br>> At the main building set each access point up on channels 1, 6 and 11/12<br>> respectively and each with it's own unique SSID in access point mode and<br>> using WPA2 security and plug them into the main LAN.<br>> <br>> At each building have a complementary WAP set up plugged into a local<br>> switch with each access point set to client mode. They should then<br>> connect to their respective access points and each building will have its<br>> own dedicated WLAN link back to the main network. It'll be like you ran<br>> some Cat5 back to the main site (though at ~30Mbit effectively).<br>> <br>> Variations on this, depending on the WAP capabilities might be, apart from<br>> AP<->APClient, are AdHoc<->AdHoc or Bridge<->Bridge.<br>> <br>> Don't forget to disable any DHCP service in the APs.<br>> <br>> All this for the price of a substitute teacher for a day.<br>> <br>> <br>> ------------------------------<br>> <br>> _______________________________________________<br>> Melbwireless mailing list<br>> Melbwireless@wireless.org.au<br>> http://wireless.org.au/mailman/listinfo/melbwireless<br>> <br>> <br>> End of Melbwireless Digest, Vol 40, Issue 5<br>> *******************************************<br><br /><hr />Get what you want at ebay. <a href='http://a.ninemsn.com.au/b.aspx?URL=http%3A%2F%2Frover%2Eebay%2Ecom%2Frover%2F1%2F705%2D10129%2D5668%2D323%2F4%3Fid%3D10&_t=763807330&_r=hotmailTAGLINES&_m=EXT' target='_new'>Get rid of those unwanted christmas presents!</a></body>
