RE: [WIRELESS-LAN] WiFi/Leaky Coax

We used TM-600 leaky Coax for several areas before moving to 802.11n.  It 
actually worked well, here is the info:

Hi William,

We installed a test setup many years ago using Trilogy AirCell Radiating Cable.
It worked as expected, even signal strength over ~200 feet from one 2.4GHz 
access point antenna. Ours was indoors, hung above a drop ceiling with offices 
on one side. Sure we could have gone farther, one AP at end of hallway, same 
signal strength on each end.

Had this pdf link saved for some information from Drexel back in 2005 using 
Leaky Coax

best!

Does anyone have recommendations for vendors selling leaky coax systems that 
support 802.11g (2.4GHz single antenna)?

We're studying ways to inexpensively provide very low density wireless coverage 
in our utility tunnels.  This would only be for the occasional worker-- our 
tunnels are small, dangerous and not open for public access.  The interior DAS 
market that use to push these solutions seems to have gone away (given leaky 
coax doesn't work well for high density/high speed and MIMO).  Traditional AP 
placement looks to be cost prohibitive.  We'd be happy to learn tips from 
anyone that has done this at their institution already.

Re: [WIRELESS-LAN] Cisco 7.3 Code and ISC DHCP

2013-02-01 Thread Revital Gorsht
This is long overdue, but to close this thread: As of 7.3, global IP Routing is enabled and, by design, an AP will drop packets that are layer 2 broadcast and layer 3 unicast, as was the case with our DHCP offers since we had a broadcast address specified on the SVI. Once the "ip broadcast-address" statement was removed from the SVI, the AP was able to process the packet and receive an IP.  Hope this helps anyone else experiencing this issue...Thanks.-The EDUCAUSE Wireless Issues Constituent Group Listserv WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU wrote: -To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDUFrom: Jason Murray Sent by: The EDUCAUSE Wireless Issues Constituent Group Listserv Date: 10/19/2012 10:16AMSubject: Re: [WIRELESS-LAN] Cisco 7.3 Code and ISC DHCPOn 10/17/12 6:39 AM, Julian Y Koh wrote: On Oct 16, 2012, at 19:49 , Jason Murray jemur...@zweck.net wrote This is not completely related, but we just upgraded one of our Cisco routers, after the upgrade dhcp stopped working because one dhcp option was blank.

Can you share router model and software versions?The last time we had this problem, I documented it here:http://blog.zweck.net/2012/10/cisco-fails-to-relay-dhcp-requests.htmlWe have also seen this exact same problem on the Cisco 6509, although Idon't remember the exact software versions.-- Jason E.
