Access Point Coverage Area

Hi
I want buy an Access point which cover 300 Meter coverage Area.
Have any data sheet or link where I can found which AP coverage how many Area, Like 1042 Access Point cover how many Feet Space.
Please Help.
Regards
Iqbal

I would tell you about my experience with an AP with external antenna 2.2 dbi:
It covers about 50+ meters (about 160 feets) in free space with acceptable coverage. You may also still get weak signal when you go further than that but it is not reliable and could get disconnected at any time.
in a cubig zone the AP could be reachable up to 30 meters ( about 100 feets) only [more or less depending on furniture and material there].
It also depends on the transmission power level at which your AP broadcasts the signal. In my prevoius explanation the highest power level is assumed.

  • Outdoor Access Points - coverage a Large outdoor area

    Hi all,
    I would like a suggestion for coverage a large outdoor area. I have critical restrictions to perform any equipment deployment.
    I have 2 km of radius to performe a wireless coverage, but I can put a Access Point just around the corners.Which AP and Antenna Cisco could I try to perform it?
    Does Cisco have any antenna with 1 to 2 km of range ? Does any client will be can reply to this distance  (1 to 2km)?
    What do you think about WiMAX ?
    thanks,
    Murilo

  • Access point coverage

    Hi,
    I have some questions for mesh wireless network.
    1. In the wcs heat maps, usually the area over the access points show as green or blue as coverage. What is the reason if near one of the ap's this colour coverage doesnt appear, even though the ap is working fine.
    should anything be done on the wcs to rectify this?
    2. In the heat maps, each access point is connected to another with an arrow line based on its related as parent or child. Not all of them show as interconnected all the time ?
    3. Will the heat maps show even the secondary available path in the arrow line format always?
    4. If i want to test the mesh links for its redundancy , how should i go about it. Is it a feasible option or will the access points divert itself to another available ap in case its primary fails as it has the different neighbors with their signal ratings.
    Thanks in advance

    Hi,
    I could not exaclty understand some of your questions but let me try replying in general:
    Color indicates signal strength in the heatmap and there is a key on the MAP shows what is the signal strength represented by each color. Red and oragne indicate very high signal. Green indicates high signal. blue indicates good signal. When the blue goes darker it means the signal goes worse.
    Those APs you can not see connected through an arrow to another AP they are either:
    - RAP: they are a parent and can not connect to others but others connect to them. at that point no child APs connected to it.
    - A MAP that could not find any close parent to connect to.
    Parents may be changed if a MAP found another parent with better signal than the one it is currently connected to. If the current parent disappears or the connection with it becomes too bad and there is another AP with better signal the MAP will move to connect through that new parent.

  • Cisco outdoor access point coverage request

    Dears,
    we need a documented recommendation from Cisco on our distances wireless coverage between two sites to go ahead on them and eliminate any problems during the implementation in the future.
             (Distance between two Buildings = 250 m)
             (Distance between two Buildings = 50 m)

    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.

    Best Practice to do Site Survey Wireless Outdoor , equipment that i could need to deploy ?
    Thanks.

    To get the best performance out of your wireless network, you must both ensure that your access points (AP) are in the most optimal locations and that other radio emitters, which can cause interference, are kept to a minimum. This requires you to periodically perform site surveys of your wireless spectrum.
    Depending on the scale of your installation, there are a number of tools available for the task, such as software that walks you through the site survey process. But no matter what size network you will have, you'll need to follow these basic steps:
    Have a blueprint or floor plan(s) of the areas you want the wireless network to cover. Some software products can work off these floor plans directly. Look at your plans and identify major building obstacles such as walls, halls, elevators and floors that will block radio signals. Also note where your users will be located -- and where they won't -- to determine coverage areas.
    Determine where you can locate APs based on power and cabling that you can run to connect the AP to the rest of the network. Remember that you shouldn't place APs close to metal or concrete walls and you should put them as close to the ceiling as possible.
    Estimate the total number of APs needed for your overall coverage. A good rule of thumb is one AP can cover a circle with a 100-foot radius. This will give you preliminary AP locations that you can use at the beginning of your survey. If you already have some APs, note their locations on your floor plans.
    Run the survey tool. Make sure to use the same AP model for the survey that is used in your actual infrastructure. See below for recommendations about which tool to use.
    Relocate APs and retest, depending on the results of your survey.
    Document your findings. Record the locations and log your signal readings and data rates observed for future reference.
    Some Site Survey Tools are 
    AirDefense Survey
    AirMagnet Survey
    AirTight SpectraGuard Planner
    Aruba Mobility Controller
    Bluesocket Wireless LAN Planner

  • New wireless network with several access points

    Hi,
    We are planing to deploy a wireless network that will cover two floors consisting of about 5 or 6 Access points. It should have 2 or 3 SSID (placing the clients in 2 or 3 different VLANS).
    What would be the best solution for this?
    I read a lot about wireless controllers. What about an option to just buy standalone access points? Are they all configured to work with the same SSID's and on the same channel?

    A centralized controller should make your life easier:
    - Centralized config - set up everything on the controller and it gets applied to the AP's.
    - Centralized monitoring - when someone has a problem, you can check the controller instead of having to figure out the AP to which they are connecting (computers don't always connect to the closest AP)
    - Dumb AP's - if someone steals one of your APs, they will not be able to learn much about your network from a lightweight AP
    - Radio Resource Management - let the controller make the channel and power setting decisions for you
    - If you use PoE, you may never have to get on a ladder and use the console port of a lightweight AP. The AP is managed by the controller, and for the rare occasion that you can't get an AP to respond - just cycle the power to the AP via the switch port.
    There are some downsides:
    - Cost of the controller (since you're buying AP's one way or the other)
    - Most cost: If your wireless network is important, then you typically want a second wireless controller as a backup
    - Probably more downsides, but my brain hurts today

  • Determining which wireless access point a computer is connected to?

    Apologies if this is posted in the wrong forum...
    I am working in a large open space where there are multiple overlapping wireless access points -- not Airports but from another vendor. Unfortunately, several computers are experiencing wireless performance and dropout issues. I think the problems may be because the laptops (both PCs and Macs) are connecting to a more distant access point across the open space which is more "line of sight" than the closer access point. We can't confirm this theory, however, because I can't pinpoint which access point we're connecting to. This is possible with a PC, but I can't find such a piece of software for my PowerBook. Is anyone aware of such a utility?
    Thanks so much.
    Brita

    Air Traffic Control widget. Search the download section for this useful widget. This widget lists all wi-fi access points, shows what channel each one is on, what the signal strength is and some vendor information.
    Whichever access point you are connected to is listed in italic on the list. I like the fact that it is a widget as it makes it very easy to access.

  • Access Point - 1262

    1. Can the C1200 antennas work on the 1262 ?
    2. Can the 2.4Ghz antenna work on the 5Ghz ports on the 1262 ?
    3. The 1262 has 6 antenna ports (3 2.4ghz and 3 5ghz), can the (3) 2.4 Ghz antenna be used only as i only have antennas for the C1200 Access point which are 2.4 Ghz.
    Thanks in advance for the help!!!

    You need to have specific frequency antennas for the ports you are connecting the antenna to. You can't use a 2.4ghz on antenna on the 5ghz antenna port. As long as the antennas from the c1200 are 2.4ghz, yes you can connect them to the 1262 only on the 2.4ghz side.
    Here is a good link regarding antennas:

  • Cisco Access Point Configuration to support 802.11b & 802.11g protocol

    How do i Configure access point to support both 802.11b & 802.11g clients on a Cisco 1121G series access point(AIR-AP1121G-A-K9)
    Regards
    Hitesh

    Hi Hitesh,
    Check out this excerpt from the 1121g AP Installation guide section on enabling the 802.11b and 802.11g radios.
    In Cisco IOS Release 12.3(4)JA and later, the access point radios are disabled by default, and there is no default SSID. You must create an SSID and enable the radios before the access point will allow wireless associations from other devices. These changes to the default configuration improve the security of newly installed access points. Refer to the "Configuring Basic Security Settings" section for instructions on configuring the SSID.
    In Cisco IOS Release 12.3(2)JA or earlier, the access point radio is enabled by default, and the default SSID is tsunami.
    To enable the radio interfaces, follow these instructions:
    Step 1 Use your web-browser to access your access point.
    Step 2 When the Summary Status page displays, click Network Interfaces > Radio0-802.11B or Radio0-802.11G and the radio status page displays.
    Step 3 Click Settings and the radio settings page displays
    Step 4 Click Enable in the Enable Radio field.
    Step 5 Click Apply.

  • E90 / E51 (and other?) --Access point groups-- ar...

    Hi All
    I‘ve seen that in the new E51 the Access point groups are gone.
    In my (older) E70 the Access point groups are installed and they are GREAT.
    It’s a pity, that they are gone, because you waste much money to your provider, and you lose connection-performance.
    Now in the E90 and E51 (AND PERHAPS IN THE UPCOMING PHONES) the possibility of building groups is not available.
    It’s a shame for a business Phone.
    You don’t know, what “Access point groups” are?
    Here the explanation of the E70’s manual:
    Email data roaming
    Access point groups.
    Your device allows roaming between wireless access technologies, such as WLAN and GPRS, for e-mail. For example, you can
    start an e-mail session at home and continue the session on your way to work. While your session continues uninterrupted,
    your handheld device switches from WLAN to GPRS and back to WLAN when you arrive at your workplace.
    In result: You have a quick and free connection at home (Wifi), you go outside, the phone switches automatically to e.g GPRS, you come in the office, the phone switches automatically to your company’s WIFI.. etc.
    You pay only the short time outside, and you don’t have to worry about changing connections.
    Let us motivate NOKIA to reintegrate this feature, so they become more professional and businesslike
    Thanks mayba

  • Invalid multimedia access point. Check multimedia ...

    I keep getting the error message "Invalid multimedia access point. Check multimedia settings." from time to time ever since I setup my 3G.
    Any thought?

    Change it to the correct one from: Messaging | Options | Settings | Multimedia message | Access point in use (the correct access point from your network probably has "MMS" in the name).
    If the correct access point settings are not on your phone, you can try: menu | Tools | Utilities | Sett.wizard

  • High Transmit discards on 1131AG Access points.

    I am running a number of AP1131AG access points that are showing transmit discards in the millions each day on the dot11G radio.
    all of these AP's are configured to use WPA/PSK and TKIP. All are running IOS 12.3(8)JEA.
    I'm puzzled by this as I also have a number of older 1231G access points that do not have the same problem.
    Can anyone tell me what might be causing such a high number of discarded packets my 1131's

    Use the command on the AP "sh dot11 associations" will give you clients which have successfully associated.  If you add the client MAC address at the end of the command you'll get a detailed information.  Look under "Signal Strength" and "Signal to Noise".  Under Signal Strength you want a value of -75 dBm or lower (lower values the better).  -76 dBm and up is bad.  Under Signal to Noise, you want a value of 25 dBm or higher (higher values the better).
    For measuring signal strength I use Airmagnet but you can use Netstumbler or Cisco Wireless Site Survey.
