Aironet 1310s Output Power Levels

I am using a SPIRENT SR5500 Channel Emulator to simulate a channel for 2 Aironet 1310s. I have the APs set to 1mW output which should be ~0dBm
yet the triggered setting for the power meter within the SPIRENT SR5500 is showing ~-20dBm at the output of the 1310s. The cable between is only 5 feet.

I am sorry! We have been struggling with this issue for weeks and just had one of the professors come in and play around with the cabling (as they do sometimes). Turns out one of our 'connector types' was faulty and once all 4 were replaced the power meter of the SR5500 Spirent was showing only cable loss at -1.5dBm and not the -20dBm that had been showing at the power meter input. Thank you so much for your quick reponse, it is good to know people care!!! Problem appears to be solved!

Aironet 1310 Transmitter Power??

I have approx 20 Cisco Aironet 1300 AP's that I use as Bridges to connect Various wide-spread, non-adjoining offices together. I do not have any problems as such, but obviously, some of the connections are stronger/faster than others due to various factors. But 1 thing I have noticed is that some of the AP's radios are rated (Transmitter Power CCK/OFDM) at 50mw and some at 20mw, and generally the 50mw AP's link seems to be faster. Therefore I have tried my best to upgrade the 20mw to 50mw - matching the radio settings, upgrading the IOS - but it doesn't change. All the AP's were purchased at roughly the same time and from the same vendor.
I have tried a few IOS's, but most of the AP's have 12.4.3g.
Can anyone explain this and/or help me upgrade to 50mw if it is possible.

Here is the URL which will help you for the configuration setting about the Cisco Aironet 1300 Series follow the configuration guide which will help you :

Aironet 1310, power injector and poe cable

Hello,
Can the power injector delivered with aironet 1310 be supplied by a PoE RJ45 cable rather than the traditionnel DC adapter?
The problem is, i thought Aironet 1310 was PoE. Which means it can be power supplied by a rj45 cable.
But, when i openned my brand new 1310 box, i realized that 1st, it needs that Power Injector to work and that 2nd, Power injector needs a power supply...
Usually when i buy a PoE access point, I just plug in my PoE rj45 cable and its power supplied :)
Anyway, i hope there's an issue for this because where the 1310 should be placed, there's only a PoE rj45 cable arriving.
Thanks in advance,
lachapelle

Hi lachapelle,
Sadly the 1310 cannot be powered by PoE ,but, the Power Injector can be up to 100 meters away from the unit.
Dual coaxial cable to run from the power injector to the 1300. See attached notes:
Cisco Aironet 1300 Series
Cisco Aironet 1300 Series Access Point/Bridge Power Injector
The Cisco Aironet 1300 Series Outdoor Access Point/Bridge Power Injector,converts the standard 10/100 BaseT Ethernet interface that is suitable for weather protected areas to a dual F-Type connector interface for coax cables that are more suitable for harsh outdoor environments. The Power Injector also provides power to the outdoor unit over the same cables with a power discover feature and surge protection. To support longer cable runs from your wireless network switch or router, the Power Injector LR is designed to accommodate up to a 100 meter coaxial cable run plus 100 meters of indoor cat5 cable?enabling total cable runs up to 200 meters. The Cisco Aironet 1300 Series Outdoor Access Point/Bridge ships with the Power Injector LR2 and an AC power supply.

Ethernet Ports
The access point/bridge dual-coax Ethernet ports consists of a pair of 75-ohm F-type connectors, linking the unit to your 100BASE-T Ethernet LAN through the power injector. The dual-coax cables are used to send and receive Ethernet data and to supply inline 48-VDC power from the power injector to the access point/bridge.
Power
The access point/bridge receives inline power from the Cisco Aironet Power Injector (hereafter called the power injector). Dual-coax cables are used to provide Ethernet data and power from the power injector to the access point/bridge. The power injector is an external unit designed for operation in a sheltered environment, such as inside a building or vehicle. The power injector also functions as an Ethernet repeater by connecting to a Category 5 LAN backbone and using the dual-coax cable interface to the access point/bridge.

Cisco aironet 1310 Outdoor access point

I am looking at outdoor access points, I want to stick with Cisco aironet, we currently have 6 of them that are 6 years old and running great, one has had a problem because of humidity, dried it out and relocated and we are good again.
I was looking at the Aironet 1310 Outdoor access point, but I can't find much information on it. I am looking to see how many SSIDs can be setup, we currently have 2 one private, and one public, this is done with VLANS. I am also looking at finding out about the power injector, it converts to coaxial cable, it has 2 RJ-45 and 2 Coaxial, does this mean if we get 2 access points, then I only need 1 power injector?
Thanks for any help you can give.

Rusty:
AP supports up to 16 SSIDs to be configured.
Multiple SSIDs with VLANs configuration is done almost the same way you do with current Aironet APs.
see here: http://tiny.cc/0qwnkw
You also need one power injector per AP. Each AP should use it's own power injector.
The two coaxial output in the power injector both are used to be connected to the AP (see below image).
The RJ-45 connectors in the power injector one of them is for Console connectivity and the other for network ethernet connectivity.

Adjusting the Maximum Power level Assignment Value

I have a deployment of AIR-CAP35021 APs. They are in 2 buildings with multiple floors. They are installed in a row down the hallways. I want to increase the power levels by using the controller and not configuring the APs individually. I have set the TPC value to -50 but I still do not reach the outer walls of the floors in some areas. I need to know what to set the Max Power Level Assignment or Min Power Level Assignment to to get the APs to power up some more. If the MAX value is 30 and the default is 30 then how will it help to adjust that value?. Any help would be appreciated.

the default on most code revs is Max at 30 and the min is -10   (note the minus sign).. If your survey was done at 25 mw with a 1252, what type of antenna was on the 1252?? if it was a stick omni it may have a higher gain than the ap's your now using. That could also be coming into play here.
so initally I'd determine what the actual EIRP you were using during the survey and then figure out how to match that now.
if you aren't familiar with EIRP it's basically the radiated transmit power at the antenna output. So a quick example
If your ap is putting out 25mw or 14dBm and you are using a 6dBi antenna then your EIRP is 20dBm or 100mw
if your ap is putting out 25mw or 14dBm and you are using a 2.2dBi antenna then your EIRP is 16.2dBm or 50mw
I believe the 3502i's use a 2.2 dBi integrated antenna.
this can cause a drastic change in your coverage area.
but if all else fails change the TPC controls so that max power is either 20dBm or 30dBm and that the minimum has a value of either 14 or 17 (no minus sign)..
30dBm = 1 watt
29dBm = 800mw
26dBm = 400mw
23dBm = 200mw
20dBm = 100mw       TXPower Level 1
17dBm = 50mw         TXPower Level 2
14dBm = 25mw         TXPower Level 3
11dBm = 12.5mw      TXPower Level 4
etc.
Hope this helps.

Aironet 1310

hi everybody i am santosh , i have a cisco aironet 1310 running 12.4(10b)JA1 and c1310-k9w7-mx.124-10b.JA1/c1310-k9w7-mx.124-10b.JA , it was working fine but suddenly i found that it has gone to AP mode while all these days it was working in Bridgemode . could any one tell me how to revert it back to bridge mode .

You are correct. The power injector is just that and the bridge unit actually has all the intelligence in it. The power injector is just your interface connection to the unit for console and ethernet and provides power to the bridge.

Aironet 1310 Antenna question

Hello,
ive got a question about the antenna of the aironet 1310. is there any difference between AIR-BR1310G-E-K9 and AIR-BR1310G-E-K9-R in basic configuration?
we had a bridge between 2 AIR-BR1310G-E-K9. but the non-root bridge went broken due its age. (connector pin was broken and couldnt get it out)
we had an AIR-BR1310G-E-K9-R on spare, so we only replaced the antenna but we coulnd not get a connection between the 2. diddnt change to power injector or config.
after som fiddling with the broken antenna we managed to get the pin out. changed the wire between the antenna and power injector and placed it back. and it worked like a charm.
so does anyone has an awnser for me? add 2 pictures. the only difference i can see are the 2 extra ports on the K9-R.
AIR-BR1310G-E-K9
http://i50.tinypic.com/uy4bn.jpg
AIR-BR1310G-E-K9-R
http://i49.tinypic.com/fwlfzo.jpg

The 'R' at the end is supposed to specify that it's the model with RP-TNC connectors for an external antenna. The model without the R should have an internal antenna.

Lost The Cisco Aironet 1310 Web Interface????

I've been having connection issues with my (2) Aironet 1310, which are setup in a bridge p2p mode. A few weeks ago we had a power outage due to a lighting storm. Well, it knocked out my non-root bridge (not connecting to the root). So I brought it back to check the configurations, but when I try to use the web console all I get is the following page:
When I click the "Web Console" link it takes me to the following page:
Is there a way to get the original web console page back?

here is the command..
archive download-sw / force-reload /overwrite tftp:///
Example..
archive download-sw / force-reload /overwrite tftp:///c1310-k9w7-tar.124-21a.JA1.TAR
to get the .TAR, go to the folder where the image is saved and then Tools >> folder options >> view >> check >> show hidden files and folders.
Now click on the image and then copy the image name and then paste the same on the CLI... then this come as IMAGE.TAR that is.. c1310-k9w7-tar.124-21a.JA1.TAR instead of c1310-k9w7-tar.124-21a.JA1
it should be c1310-k9w7-tar.124-21a.JA1.TAR
lemme know how this works out for you!! if you face any difficulties while upgrading please open up a TAC case.. we wil solve this in less than 5 minutes... and the network wil be back up!!

Output sound level from gramophone and from computer should be the same

Dear friends,
Why the output sound level isn't equal if we listen the LP directly from the gramophone (AUX1) or from the computer during the recording the track on the computer?
We are using The E-MU 0404 USB 2.0 Audio/MIDI Interface:
http://ixbtlabs.com/articles2/proaudio/emu-0404-usb.html
http://www.emu.com/products/product.asp?product=10447&nav=features
and we have connected E-MU with the (gramohone) speakers through the headphone output on the E-MU and turn the headphone level to the maximum, but the sound level is still lower from the same speakers.
If we compare the track after the recording with the LP on the gramphone is the level of the sound the same/equal.
So we need to have all three sound levels equal:
-from the LP form the gramophone
-from the computer during the recording
-from our track on the hard disk after the recording
Thank you for your answer.

function(){return A.apply(null,[this].concat($A(arguments)))}
Connecting loudspeakers to the headphone output on the E-mu sounds like completely the wrong thing to do altogether - you should
only connect headphones to a headphone output, and nothing else at all.
We will buy the cable as you mentioned and connect it in the line level (S/PDIF).
function(){return A.apply(null,[this].concat($A(arguments)))}
Almost certainly you will need to adjust the monitoring levels in Patchmix to get this the way you want it
Then we will try to adjust the monitoring levels in Patch (I will report if and how did we manage it).

Configuration of a Point to MultiPoint link with Cisco Aironet 1310 bridges

Hi All,
The previous problem of which I started another conversation here:
http://forum.cisco.com/eforum/servlet/NetProf?page=netprof&forum=Wireless%20-%20Mobility&topic=General&CommCmd=MB%3Fcmd%3Ddisplay_location%26location%3D.1ddba023
somehow dissapeared. It could have been a problem of interferences.
I have another issue with other (multipoint) wireless WAN link, which I hope has a solution.
On the central node, we have an Cisco Aironet 1310 bridge configured as root-bridge. It has a panel of four vertical polarity 17 dBi panel 90? antennas, with more than enough gain (there is a 250 mWatts 802.11 b/g amplifier, before the 4-way splitter) and excellent line of sight to three remote bridges.
The three (03) remote bridges are also Aironet 1310 models, confidured as non-root-bridges.
The problem we have is that it seems that when the three remote links operate concurrently the amount of lost packets is huge. When I shutdown the radio interfaces of two bridges, the remaining bridge makes an excellent link with the central node.
It seems that some hours are more critical than others, also the links operate much worse when there is some (small) network traffic in them.
I have read the 1310 manuals, and I can't find a sample configuration for point to multi-point links.
Does someone knows what radio interface configuration should I need to use to establish better quality communication?
I mean, perhaps the 1 x root - 3 x no root configuration is not recommendable for the multipoint link configuration.
Any hints will be welcome.
Best Regards,
Igor Sotelo.

Hi All,
Thank you for the information. I configured the distance on the root bridges, but the links showed instability.
I'm using a bi-directional amplifier. It has two pieces. According to the manuals, one is installed indoors, the other outdoors. I'm not sure if the indoors piece has the transmition module or it's only the injector.
We could establish connection at 7 km (around 4 milles) distance from the central point, using 24 dBi antennas on the other side.
However, we have issues with a near located point that is only 1.2 Km (around 0.8 milles) away and has a 13 dBi integrated patch antenna. The signal strenght value we get there is in the -62 to -68 dBm range, and is noticiably (5-10 dBm) lower than the strenght we get at other points of the link. And I have trouble establishing a high quality link with that point, using OFDM modulation. I tend to think that if I remove the amplifier I'm not going to reach that point at all. The EIRP on the central iste is 34 dBm / 2.5 watts, without amplifier it would be 26 dBm / 0.4 watts.
On the opposite sites the EIRP is 33 dBm / 2 watts using CCK or 28 dBm / 0.63 watts using OFDM.
When one looks at the central site from that point, an Motorola Canopy with passive reflector (EIRP 48 dBm or around 64 watts) can be seen. It doesn't have the same direction, but the opposite site must be large distance and could interfere with my wireless network. Attached is an amplified photo of the view. It's safe to assume that the Canopy operates in the 2.4 GHz frequency range.
Once I connect the point at 1.2 Km, the multipoint link loses its quality, and soon the lost packets get too frequent.
The CCK seems to be much more interfered than OFDM, I guess because of that canopies.
Another thing I'm wondering about is if the Aironet 1310 can continuosly switch CCK-OFDM over the same point - multipoint link, without losing packets.
What other parameters should I tweak? Is there a way to avoid interferences fromt the canopy?
I would like to apply 100 mWatts local power using the radio with OFDM, but it seems that's not possible.
Best Regards,
Igor Sotelo.

Aironet 1310 errors...

Hi,
we have got two ofices in different area. We decided to connect them with two AP's Aironet 1310 with mode point-to-point bridge. We have voice traffic over this wi-fi channel. If we use IOS 12.3(4)-JA we have noticed many errors in the logs 1310 such as "DOT11-4-MAXRETRIES: Packet to client [mac] reached max retries, remove
the client" or "DOT11-4-UPLINK_LINK_DOWN: Interface Dot11Radio0, parent lost: To many retries". The connection betwen AP's is down at regular intervals and not established again. The connection has upped only after disconnect and reconnect the power injector power jack. Time to response is less than 100 ms for ping. We have changed IOS ver 12.3(8)-JA2 and unfortunately it doesn't help, though the errors has noticed less, but Time to response is between 70 ms and 5000 ms. It is too bad for normal work in our ofices, we wanted to have Time to response about 50 ms. Could you advise something?
Thanks.

Packet to client MAC reached max retries, remove the client" is happened when your client try to associate AP which doesn't support client function correctly (usually authentication type doesn'tmatch).

Multiple Aironet 1310 AP's / One Wirless Network / How To???

I have been given six AiroNet 1310 access points and would like to create on one unified wireless network using some or all of them.
I am wondering what would be the best direction to start this. I assume they would have to be in some sort of "cluster" mode.
I guess whatever would be the easiest way to implement this would be what i am looking for.
The reason i need to do this is because it will be for a courthouse, we want to cover pretty much the entire building, (3 stories) and also outside.
Any suggestions, help, or how to do this would be appreciated. Thanks.
Oh and i know the AP's will need to get addresses from somewhere, so i planned to hook them into the existing network and give them static IP's, which is also where the network and internet parts come into play for the clients once this is up and running.
Thanks again.

If you need to configure the access point/bridge locally (without connecting the access point/bridge to a wired LAN), you can connect a PC to the Ethernet port on the long-reach power injector using a Category 5 Ethernet cable. You can use a local connection to the power injector's Ethernet port much as you would use a serial port connection.
Make sure that the PC you intend to use is configured to obtain an IP address automatically, or manually assign it an IP address within the same subnet as the access point/bridge IP address. For example, if you assigned the access point/bridge an IP address of 10.0.0.1, assign the PC an IP address of 10.0.0.20.
Step 1 Open your Internet browser. The wireless device web-browser interface is fully compatible with Microsoft Internet Explorer version 6.0 on Windows 98, 2000, XP platforms, and with Netscape version 7.0 on Windows 98, 2000, XP, and Solaris platforms.
Step 2 Enter the wireless device's IP address in the browser address line and press Enter. An Enter Network Password screen appears.
Step 3 Press Tab to bypass the Username field and advance to the Password field.
Step 4 Enter the case-sensitive password Cisco and press Enter. The Summary Status page appears.
Step 5 Click Express Setup
Step 6 Enter the configuration settings you obtained from your system administrator
Step 7 Click Apply to save your settings.
Step 8 Click Network Interfaces to browse to the Network Interfaces Summary page.

How to reduce Hub 3 output POWER?

I use my laptop in the same room (~5m) as the router and wondered if there was a way of reducing the output power from the Hub 3 antenna, which has a range of ~40m? I have two young children in the room and am concerned about wi-fi signal levels. A colleague mentioned that he can reduce the output power of his APPLE router easily. Is there a similar option for the Hub 3 BT product? I realise that if I do not have the laptop switched on, i.e. no activity, then the power level drops automatically, which is a great feature. Thanks, Fred.

There is no facility to reduce power apart from the power save option which turns the WiFi off.
The maximum power allowed by WiFi is 100mW (100 milliwatts) which is very small. If you are concerned about WiFi, then it would be better to turn it off, and connect to your laptop using an Ethernet cable.
You can extend the Ethernet port of the hub by using Powerline adapters. Which use the mains wiring to carry the data.

Anyone get to know what's the output power of the audio system?

Hi. It's there anyone could tell me what's the output power of the 2.1 audio system in this 24" LED display?? Thanks

Gabi759,
The output on the Audigy 2 ZS is Line Level. We no longer use amplification on the card as that can cause distortion and an overall loss of audio quality. You may want to look at either replacing your speakers (as few sound cards have amplification) or get a preamp for them to power them.
