Aironet LAP 1140 vs LAP1040

Hi to all,
Could someone please tell me the differences between these two AP families (Aironet 1140 vs Aironet1040) ?
I've seen that the LAP version of the 1040 doesn't support the feature Extended Coverage..what is this feature about? Antenna specifications?
Moreover these LAP could be use in combination with:
- WLC 21XX Series and
- Switch 802.3af compatible (up to 15.4W per port)
right?
Thnx for the support
Omar

TxR:S
T - Transmit
R - Receive
S - Spaitial
You will fine 802.11n with the following flavors:
1x1:1
1x2:2
2x2:2
2x3:2
3x3:2
Cisco Aps support 2x2:2 or 2x3:2. Atheros will have their 3x3:3 chips coming out in April. Not sure what Cisco's road map is to support it. The spatial is your "money". Each spatial equates to 150mb, so you will see 3x3:3 equates to 450 mb.Thats why with Cisco APs and others, you will only ever get 300 with xXx:2.
** EDIT **
Let me add further, 2 on the transmit means you will use no more than 2 antennas to TX on. 3 on the receive means you will use 3 antennas to rx on. The spatial is your streams. if you have a 2 stream AP, that the most streams you will have. AND, thats if your environment is favorable to use 2 streams... Just because it can do 2, doesn't mean it will always do 2 .. it takes advantage of multipath ...
802.11n although by standard could support  600 4x4:4, its VERY unlikely we will see that in the enterprise. Atheros mentioned they will not support development of the 4x4:4 chip. Why you ask ? They said that 802.11ac should be a quick ratification.  802.11ac, you will be able to do 8x8:8, hence GIG over wireless.
Make sense?
Please rememeber to rate helpful post ..

  • LAP 1242AG Can't use as a repeater

    i bought 2 aironet LAP 1242AG AP's. first i didn't know i had to have a cisco controller to configure/use these. so i flashed the OS to ISO the newest one. so now i can go to the GUI and configure.
    this is that i need these 2 AP's to do. there for a client who wants wireless in 2 pool areas. so i purchased these cause they have good range.
    they have a linksys wrt 160N router now. i am trying to use the LAP 1242 AP to get a signal off the linksys router to repeat it. i read some non-cisco router can't do this. so i don't know if i am setting this AP up correctly or just the linksys can't do this.
    so if anyone could shed some light on this would be great. if the linksys router can't do what i want it to do, can someone reccommend a router that can.
    so 1 linksys wrt160 will be for one of these cisco AP's and and another linksys wrt160 will be in bridge mode at another building and i need this one to give wilreless to the cisco AP.  now i can't run a network cable to either locacation of where the AP's are gonna be. so they need to pick up the signal wireless.
    thanks in advance for the help.
    Joey

    Ha ha
    I am in my house!! not feeling sleepy and its mid night here and waiting for questions to answer
    Ok lemme come back.. I guess Router doesnt support IAPP.. so just buy another AP.. replace your Linksys with 1242..
    Site A ---------------------------- Site b
    1242 as Root                    1242 as Non root with wireless clients
           |
           |
           |
           |
       Sire C
    1242 as Non-Root with wireless clients
    Assuming we have the Line of Site between the sites..
    By this setup i guess all your clients will get the wireless signal and then they can connect,
    lemme know if i am visualizing your issue correctly..

  • 1140 AP's internal antenna radiation pattern

    Is it right or not?
    1. Cisco Aironet 1040, 1140, 3500i Series Integrated Antennas Diagrams show Azimuth Plane Radiation Patterns and Elevation Plane Radiation Patterns when AP is mounted vertically on the wall (red LED above Cisco logo). So "Zero" on Azimuth Plane points to direction rectangular to AP's case plane (mounting wall plane), "Zero" on Elevation Plane points to ceiling and "180 degrees" points to floor?
    2. Radio waves polarization in this case would be linear, in direction from ceiling to floor?
    3. If AP would be mounted horizontally on the ceiling, then polarization would be in direction parallel to floor axis X and rectangular to floor axis Y? So induced signal on notebook integrated antenna, oriented rectangular to floor axis X, would be near zero?
    See "Cisco Aironet Antennas and Accessories Reference Guide." Page 69.

    Hi Valentine,
      Here is Cisco Antenna Pattern Guide:
    http://www.cisco.com/en/US/prod/collateral/wireless/ps7183/ps469/prod_white_paper0900aecd806a1a3e.html
    I had same problem on that, because the antenna pattern of 1130, 1140 and guides are not so clear.
    From the guide you can see plate antenna forward direction which means Cisco logo direction ( if you place on wall it pointing horizintol, looking front) is Y, vertical Z, horizintol X(Left and right side), then if you see the 1130, 1140 antenna pattern. Azimuth is almost 360degrees which means doesn't matter Y and X (Ф), the problem Y and Z(Ө) , from the guide there mentioned most of the antenna Y(direction front) is 0degree, and some of them 90degree showed. So now if you trying to understand 1140 antenna Ө pattern, it would be no wave directing to front, you can see from 20-30degree till 90degree to tilting down side, and up side is like this, and pattern is 180degree waving to back side of antenna , which sounds crazy, so it is making complicated.
    I have 1130, if you see 1130, from that point front radio pattern of that antenna tilting down side around 45degree(from 15-60) and also 180degree to backside .
      I am confused and maybe what i think is true because on 1130 Elevation beamwidth is 50degree so it would be almost.
    But other hand if Y front side is directing 270degree on the antenna pattern elveation there is no need worry we all, it is almost 180degree which means covering whole front of antenna Ө tangle.

  • AP continuously renewing IP address

    Hi Friends,
     I installed 4 new access points in our remote site to register it to the controller in the HQ using flex connect. And configured the distribution switch in the remote site as  dhcp server. 
     A new vlan was created for this purpose.
     Now, the APs are getting the IPs, but they are continuously renewing it, say every 20 - 30 seconds.
     The interfaces connected to the APs are stable. No ups and downs..
     What could be the reason.?
     Configs below;
    Ip dhcp pool AP_MGMT
      Network 192.168.77.0 255.255.255.0
      Default-network 192.168.77.100
     option 43 ip 10.1.2.60
    interface fa5/35
      description to AP
      switchport mode trunk
      switchport trunk native vlan 777
      no shutdown

    Hi,
    You need to make sure below points and then check.
    You can deploy a FlexConnect access point with either a static IP address or a DHCP address. In the case of DHCP, a DHCP
    server must be available locally and must be able to provide the IP address for the access point at bootup.
    FlexConnect supports up to four fragmented packets or a minimum 500-byte maximum transmission unit (MTU) WAN link.
    FlexConnect is supported only on the following access points: Cisco Aironet 1130AG, 1140, 1240, 1250, 1260, AP801, AP802 and Cisco Aironet 600 Series OfficeExtend Access Points.
    Round-trip latency must not exceed 300 milliseconds (ms) between the access point and the controller, and CAPWAP control packets must be prioritized over all other traffic. In cases where you cannot achieve the 300 milliseconds round-trip latency, you can configure the access point to perform local authentication.

  • Cisco WLC 2504 and ways to authenticate users

    Hi All,
         What is the ways to make user authenticate to WLC 2504 and what is the best and simple way and what is the differences btw each method _i mean for example need radius server or something else to be exist_ ?
         and any one can give me case study for this issue
    System consist of Cisco 2504 and Cisco LAP 1140
    Thanks

    To implement radius based authentication is the best practice for the small & enterprise environment.
    Information About RADIUS
    Remote Authentication Dial-In User Service (RADIUS) is a client/server protocol that provides centralized security for users attempting to gain management access to a network. It serves as a backend database similar to local and TACACS+ and provides authentication and accounting services:
    •Authentication—The process of verifying users when they attempt to log into the controller.
    Users must enter a valid username and password in order for the controller to authenticate users to the RADIUS server. If multiple databases are configured, you can specify the sequence in which the backend database must be tired.
    •Accounting—The process of recording user actions and changes.
    Whenever a user successfully executes an action, the RADIUS accounting server logs the changed attributes, the user ID of the person who made the change, the remote host where the user is logged in, the date and time when the command was executed, the authorization level of the user, and a description of the action performed and the values provided. If the RADIUS accounting server becomes unreachable, users are able to continue their sessions uninterrupted.
    RADIUS uses User Datagram Protocol (UDP) for its transport. It maintains a database and listens on UDP port 1812 for incoming authentication requests and UDP port 1813 for incoming accounting requests. The controller, which requires access control, acts as the client and requests AAA services from the server. The traffic between the controller and the server is encrypted by an algorithm defined in the protocol and a shared secret key configured on both devices.
    You can configure multiple RADIUS accounting and authentication servers.For example, you may want to have one central RADIUS authentication server but several RADIUS accounting servers in different regions. If you configure multiple servers of the same type and the first one fails or becomes unreachable, the controller automatically tries the second one, then the third one if necessary, and so on.

  • Different between H-REAP mode & Office Extention in Cisco AP

    What is the different between H-REAP mode & Office Extention .
    Hope both created for remote branch support , but it seems only H-REAP can route the data traffic locally & forwards control traffic to remote WLC.
    This Office extend feature forwards both Data & Control traffic to office WLC.
    Is my understanding correct ..please help me.

    Hello,
    As per your query i can suggest you the following solution  -
    Hybrid Remote Edge Access Point (H REAP) is a wireless solution for branch office and remote office deployments. It enables customers to configure and control access points in a branch or remote office from the corporate office through a wide area network (WAN) link without deploying a controller in each office. The H REAP access points can switch client data traffic locally and perform client authentication locally when the connection to the controller is lost. When connected to the controller, H REAPs can also tunnel traffic back to the controller.
    The Office Extend AP (OEAP) is a specific submode of H-REAP, and is supported on the Cisco Aironet 1130AG, 1140, and 3500i (not 3500e) APs. You can also use the Cisco Aironet 600 AP, which is a model dedicated to the OEAP mode. This dual-band (2.4-GHz and 5-GHz) AP supports 2 corporate SSIDs and 1 home SSID, up to 15 clients, and offers 5 Ethernet ports at the back (1 uplink port, 1 corporate VPN port, and 3 local switch ports). Other OEAP-capable APs support 16 SSIDs (15 corporate SSIDs and 1 personal SSID).
    Hope this will help you.

    When you upgrade Cisco Aironet APs from autonomous Cisco IOS Software to lightweight mode, the LWAPP Recovery Cisco IOS image is the software that is loaded. The LWAPP Recovery Cisco IOS image does not support OTAP. In order to support OTAP, Aironet LAPs must first join a WLC in order to download a full LWAPP Cisco IOS image.

  • LWAPP to Autonomous/IOS

    I have a Aironet LAP-1232AG (AIR-LAP1232AG-A-K9) that I need to downgrade to an Autonomous AP. I can't find any documentation on how to do this. I have downloaded c1200-k9w7-tar.123-8.JA2.tar and set up a tftp server, but the LAP won't connect.
    Any help would be GREATLY appreciated!

    Hi Tom,
    Here is the related info :)
    Using a TFTP Server to Return to a Previous Release
    Note This section does not apply to Cisco C3201WMIC and Cisco C3201LAP.
    Follow these steps to revert from LWAPP mode to autonomous mode by loading a Cisco IOS release using a TFTP server:
    Step 1 The static IP address of the PC on which your TFTP server software runs should be between 10.0.0.2 and 10.0.0.30.
    Step 2 Make sure that the PC contains the access point image file (such as c1200-k9w7-tar.122-15.JA.tar for a 1200 series access point) in the TFTP server folder and that the TFTP server is activated.
    Step 3 On the PC where the TFTP server is located, perform these steps:
    a. Disable any software firewall products, such as Windows firewall, ZoneAlarm firewall, McAffee firewall, or others.
    b. Ensure all Windows files are visible. From Windows Explorer, click Tools > Folder Options > View > Show hidden files and folders.
    Step 4 Rename the access point image file in the TFTP server folder to c1200-k9w7-tar.default for a 1200 series access point, c1130-k9w7-tar.default for an 1130 series access point, c1240-k9w7-tar.default for a 1240 series access point, and c1250-k9w7-tar.default for a 1250 series access point.
    Step 5 Connect the PC to the access point using a Category 5 (CAT5) Ethernet cable.
    Step 6 Disconnect power from the access point.
    Step 7 Press and hold MODE while you reconnect power to the access point.
    Step 8 Hold the MODE button until the status LED turns red (approximately 20 to 30 seconds) and then release.
    Step 9 Wait until the access point reboots, as indicated by all LEDs turning green followed by the Status LED blinking green.
    Step 10 After the access point reboots, reconfigure it using the GUI or the CLI.

  • Android 4.1 tablet not connecting to Aironet 1140

    Hello community, I am having an issue with my Android Tablet running 4.1 (Jelly Bean). It is able to the SSID, but when I try to connect - it stays connecting and then says saved, and never connects, as it does not pick up an IP address. I updated the firmware on the Aironet 1140 due to my Windows 8 pc's not connecting as well, it solved my Windows 8 problem, just not my Android Tablet problem. My Ipads do work. Just any android device I connect...
    Anyone, ran into this issue that can assist?
    Thanks in advance.

  • Cannot get Windows 7 x64 laptop to connect to AIRONET 1140 WAP

    I recently changed the configuration of my Aironet 1140 from WEP to WAP2-Enterprise to make it more secure. I am using the WAP as the radius server.

  • Aironet 1140 54Mbps connection speed

    We are having some issues with our AP: Aironet 1140 at our head office where people are complaining of slow connection speeds.
    I have gone through the configuration on the controller and noticed that all Clients were connecting at 802.11g connection speeds (54Mbps).
    I have noticed in the configuration page on the controller Wireless>802.11b/g/n > High Throughput is disabled.  (See attached screenshot)
    I don’t want to just enable this setting in case it disconnects all the users from all the AP’s not just the ones at head office.
    We use 802.1x for authentication and Machine certificates.
    All Clients connect using WPA2.
    Would this settings increase the connection speed up to 802.11n?
    Is there a way to just enable it on 1 AP to trial it before enabling it on all the AP’s?

    The wireless speed is only 15-20mbps Max. When connected via Lan cable the speed is around 45mbps.
    As scott said, you are getting this speed due to the half duplex nature of wireless. If your AP model is 1142, then you can configure radio1 interface (5GHz)  for the SSID. You MUST use WPA2/AES  or Open Auth in order to get 802.11n speeds which is greater than 54Mbps. I do not think you are using that at the moment & it may be a reason why clients data rates not get 802.11n speeds.
    Below shows different AP model max data rates. If your clients having multiple spatical stream (SS) capability they can get higher speeds. Note that 20MHz BW is the max you can get in 2.4GHz band & 40MHz bandwidth you can get from 5GHz with channel bonding. So 5GHz is always better if you looking for higher througput (but obviously client should able to connect in 5GHz)
    Adding antoher AP would be a good idea (without bridging) & see wether you could afford 2602 or 3602 which can go upto 450Mbps data rates . Practically if you could you get 50% (which is around 200Mbps) that is really good. Note that this is total AP througput & if you connect multiple clients that will be shared among users.
    Also keep in mind when you add multiple users all users aggregate bandwidth is limited to 50Mbps due to your WAN link speed. So that would be the bottleneck within your network.
