Which outdoor access points to connect two buildings (500ft distance)?

Hello,
We have a client that needs to wirelessly connect two buildings at their location, around 500ft over a parking lot. There are no significant line-of-sight obstructions. Which outdoor access points would be most suitable for this, and what is the maximum speed we can expect from such a connection?
Thanks
Tim

You can configure point-to-point wireless bridging.
Wireless Bridges Point-to-Point Link Configuration Example

Next, you can use either indoor access point or outdoor/mesh access point. I'd recommend indoor. Since it's going to be point-to-point, no need to get an AP that can support 802.11n because it's not supported. This brings your choices down to a Cisco 1242 (dual radios).
In regards to antennaes, AIR-ANT2410Y is a contender. Have a look at the complete portfolio for more information.

Is there any way I can control which specific access point I connect (and stay connected) to from amongst a set of access points with the same SSID?

I'm working from a boat in a harbor in which the ISP has deployed numerous access points around the periphery. All the access points share the same SSID and each is configured to use either channel 1, 6 or 11. From my location, there are over a dozen of these access points "visible" (based on the the output of WiFi Scanner) with a range of RSSI and S/N values that vary over time.
The ISP has told me that the quality of my connection should be "perfectly fine" for any access point with an RSSI value better than -75, but I know from experience that my connection quality is miserable (i.e. < 50Kbps download) for almost all of these, including those with RSSI values better than -75. There is at least one exception, however, which gives me on the order of 2Mbps download, which is "great" in this context.
I've tried using a more powerful USB antenna plugged into my MacBook Air (mid 2011), but as far as I can tell, it really doesn't make much difference. Neither does my location within the boat. The overriding factor seems to be which access point I happen to connect up to.
I should point out that the closest access points are about 75 yards away, with many of them being several hundred yards away or more. I'm guessing that even though the signal strength of some of the distant access points is causing them to get "chosen" some times, the results are unacceptable due to the distance.
I'm hoping that I can determine, through experimentation, which access point(s) provide(s) acceptable performance and then configure my Mac to limit my connection to those points through whatever mechanism I need to use (e.g. channel, MAC id, etc.).

Establishing a wireless connection with a client computer is left to the access point for various reasons. One reason that your Mac may not connect to the strongest access point is that it may have reached a limit of the number of clients it can serve, leaving it unable to accept a connection with another. The limit may not be very large.
Suppose that happens, and your Mac establishes a connection with a more distant access point having a weaker signal. Then, suppose a client drops off the network. Doesn't this mean your Mac will switch to the stronger access point? Not necessarily. The throughput delivered to and from your Mac would have to drop below a threshold specified in the AP for it to drop the client, leaving your Mac free to connect with another one. The reason for this is to prevent rapid switching from one AP to another in an area in which two signals are of approximately equal quality. If that were to occur the frequent and repetitive handshaking between the two devices would slow throughput to zero.
In an environment in which several access points are broadcasting the same SSID, Apple provides no insight as to how it determines which access point to choose. This is the reason I suspect this "choice" is a function of the router, or access point. The connection originates with it, not the Mac.
Now, what would solve your dilemma would be to determine a way to control the access point with which your Mac connects, by specifying the access point's unique MAC address for example. In this happy circumstance, you could maintain an editable "whitelist" or "blacklist" of the harbor's access points and be able to choose which among them you prefer.
I do not believe OS X maintains such a record of MAC addresses though, only those of the routers it uses. If I am correct about that, such a solution is unlikely to exist. Don't let that discourage you from searching for one though... I would concentrate on something like "selecting access point by specific MAC address".
I did find this patent application though:
Roaming Network Stations Using A Mac Address Identifier To Select New Access Point
Perhaps it's a start

Which Cisco Access Point is Waterprof ? (outdoor:BR1300 + AIR-ANT24120)

hi,
My questions to the community :
i have to choose for a customer some 50 Access points but that must have an external antennas with at least 8 dbi as gain and to be waterprof
for me the BR1300 + AIR-ANT24120 is a good choice if the BR1300 is Waterproof (For me :normaly all Cisco Access Point Outdoor must be WaterProof : but i want to have a confirmation with a document if possible )
and it's interessant to knew ,which Cisco Access Point is Waterproof ?
Think you All !
Zammit Ikbel

the 1310 is going to be waterproof, as is the 15xx product line, (152x and 155x). All this can be found in the data sheet for the AP.
That being said, you can also put any of the external AP into a NEMA enclosure, and have it be waterproofed, so long as the enclosure is rated as such.

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)?

Regarding cisco 1400 and 1500 outdoor access point doubt

Hi,
I have a requirement of installing 1400 outdoor access point in bridge mode .
client has got three remote offices which will be connected through 1400 outdoor access point.
but i came across about lightweight and autonomous version where i am quite confused.
which version is available in market especially for 1400
If i could get information about 1500 also , it would be great help .
If i want to connect all the remote offices in brigde mode . which will be convinient for me ?
If I could get any link with datasheet for both the access point seperately, it would be great.

Hi,
1500 is for MESH network.. 1400 is for bridging in autonomous mode.. most of the time we use 1400 for bridging between two diffrent sites..
1400 bridges do not work in LWAPP mode.. its always Autonomous.. where in the 1500 canot work in autonomous as well and needs a WLC..
here is the datasheets for 1400 and 1500..

Define access point to connect?

A couple of applications on my phone, particularly Ovi Maps keep doing this and it's getting REALLY annoying.
Start using the application, it comes up with the following:
"Network connection required.Define access point to connect?
Then it'll give me a selection from a list of my networks various protocols.
It will regularly ask me again and again while the app is running, often coming up in front of other applications i am using at the time!
How can I stop this?
I don't want to have to define anything for specific applications. I want my phone to connect in one of two ways without my input:
1. If I am within range of a Wifi connection it knows, connect via that.
2. If not, connect via 'O2 Active'
Is there a way I can set this so my phone just does the above and never asks again?

It is the Assisted GPS positioning method access found in Menu > Settings > Application Settings > Positioning > Positioning server use which keeps asking for a Network access point not OVI Maps application itself which may be set "Offline" or "Online".
If you have not set "Save location info" = No - in Camera > Options > Settings - you may get the same response.

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.

Wireless bridging is not working in 1552 outdoor access point and 2602e indoor access point.

Hi,
I am have been tested wireless bridging with 2 indoor Cisco 2602 access point by following the attached document and its working fine without any issue.
After then I made one Cisco 1552 EU-M-K9 outdoor access point as RAP, then connect to this RAP with one 2602 mesh access point. But its not working, mesh access point is just start scan the signal to get associate with RAP, but not getting established. Is there any specific configuration required to connect between outdoor and indoor access point. Kindly find the attachment and advise.

Outdoor Access points PoE power issues

We are currently deploying 5 more 1530 Outdoor Access points to the existing 2504 wireless controller with 15 Airlap 1142n AP's.Now all the AP's are connected to the catalyst cisco 2960 switch.
a)Is the catalyst 2960 switch supply enough power for the outdoor AP's or I have to use any external power injector source?

Is the 2960 370W or 720W?
"The Cisco Aironet 1530 Series can be powered over the Ethernet connection with power directly from an appropriately powered switch port or from an inline power injector."
The 1530s take:
1530I: < 30 W
1530E: < 25 W
(http://www.cisco.com/c/en/us/products/collateral/wireless/aironet-1530-series/data_sheet_c78-728356.html)
AP1140: 12.95 W
(http://www.cisco.com/c/en/us/products/collateral/wireless/aironet-1130-ag-series/datasheet_c78-502793.html)
So depending on the 2960 in question, I believe you may be able to power them up, do you have anything else hanging off the switch?
We had issues with lighting arrestors causing PoE failures in the past. Removing them cleared the issue.
Please rate and marked if this answers your question.

Lightning Protection - Outdoor Access Point 1310 ?

Hello,
what exactly do i need to protect my Outdoor Access Points an the Infrastructure behind the AP? The Access Points are mounted on the roof of a building.
Is the grounding kit enough? Do i need Lightning arrester? Is there a complete Manual or something like that?
Thanks for your help! I search the whole day without finding any concrete advices..

And how can i protect my equipment from a directly lightning strike? one of the Access Points is the highest Point on the roof. Is there an other way to protect it without a real lightning arrester? (not the Cisco product..)

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.

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.

Image Recovery for Cisco Aironet 1300 Outdoor Access Point

We purchased two 1300 APs for outside. There is a new release for the image that we wanted to use so, we have the latest security updates. We downloaded, logged onto the access point just fine, but the image never took. After four hours with a direct connection, it was still going and this morning we came in and it just keep rebooting. Our network guy states it looks like a corrupt image. We can barely do anything and since there is no "mode" button like the earlier models, I have not found anything on web sites or forums to help us reload a good image to the access point. I would appreciate any insight someone has and/or where to look for this. I logged on and downloaded about every manual on the 1300 I could find, but have not found a good way to fix this. Not even the upgrade tool will connect since it just keeps rebooting.

Hi Bruce,
Because (as you correctly noted) the 1300 does not have a mode button you could try this method;
Complete the steps in this section in order to reset Cisco IOS Software-based bridges:
If the privileged command prompt ap# is available in the CLI, the write erase command and the reload command erase the startup configuration and reset the unit.
If the GUI is available, choose System Software > System Configuration. Press the Reset to Defaults button.
Aironet 1300 Series Bridges do not have a MODE button to reset the AP to factory defaults. So, if neither the GUI or CLI is available with sufficient privileges, complete these steps to delete the current configuration and return the entire bridge settings to the factory defaults using the CLI.
Open the CLI with a Telnet session or a connection to the bridge console port.
Reboot the bridge by removing and reapplying power.
Allow the bridge to boot until the command prompt appears and the bridge begins to inflate the image.
Press ESC when you see lines that are similar to these on the CLI:
Loading "flash:/c1310-k9kw-7mx.v122_15_ja.200040314-k9w7-mx.v122_15_ja.20040314"

After the bridge reboots, reconfigure the bridge with the web browser interface, the Telnet interface, or Cisco IOS Software commands.
Note: The bridge is configured with the factory default values that include:
The IP address, which is set to receive an IP address with DHCP. If you do not have a DHCP server, you can access the bridge using the default IP address of 10.0.0.1 using HTTP/HTTPS or Telnet. Once you gain access to the bridge via Telnet or GUI, you can modify the IP address of the bridge.
Note: This default IP address of 10.0.0.1 becomes available only for a short period. So, make sure that you assign your own IP address to the bridge within that period of time.
The default username and password, "Cisco".
From this doc;
http://www.cisco.com/en/US/products/hw/wireless/ps430/products_password_recovery09186a00800949d0.shtml#ca_1310_ser
One other thing, be careful with the new IOS that you aren't loading a LWAPP Recovery Image. (it almost sounds like what may have happened)
Hope this helps!

Connecting two buildings with 1242AG?

Hi,
I already have a Aironet 1242AG in one building but need to bridge between this building and the building next door. Both buildings have a wired network in the building. The shortest distance is about 50 ft. So I am thinking about getting another 1242AG for the second building, set it in Non-Root Bridge role and change the current 1242AG to Root Bridge role. This way, wired and wireless clients on both sides can get on to the network as a while. Does it sound like a reasonable plan to bridge the two buildings?
One point I am not clear is Cisco's explanation of non-root bridge: "Non-root bridge —Not connected to a wired LAN, associates to a root bridge, supports wireless clients, and supports wired clients." So can I connect the Ethernet port of non-root bridge to the wired LAN in the second building thus connect the wired clients on that network as well? It says "not connected to a wired LAN" but also says "supports wired clients."
Is "Workgroup Bridge" role also an option? Thanks,

Surendra and Dmantill,
Thank you both for the tips! One more question if I may:
Based on the fact that the closest distance between the two buildings is about 50 fts (will put by the windows), do I really need high gain antenna (part #AIR-ANT1728) instead of the "standard" antenna for 1242AG (part #AIR-ANT4941)?They both are omni-directional antenna but cost delta is 7 times.
I'd ask these kind of questions to my vendor but their sales keep pushing for fancy outdoor model that costs > $3K. I am trying to cut costs whereever I can, especially considering the distance is only about 50ft.
Thank you again!

Cisco 802.11n Outdoor Access Point

I have to propose to a client a 802.11n outdoor Acess point with external antenna, tha gain must be >8 dbi.
Which cisco model should i use ?

I have to propose to a client a 802.11n outdoor Acess point with external antenna, tha gain must be >8 dbi.
DO NOT, under any circumstances, use 1260 or 3500e if you plan to use antennas > 6 dBi. These two models DO NOT SUPPORT antenna gain higher than 6 dBi. The only two 802.11n-capable WAP that can support high-gain antenna of > 6 dBi are the 1250 and the 3500p.
Antenna Product Portfolio for Cisco Aironet 802.11n Access Points
The 1250 is End-of-Sale (End-of-Sale Date: 12 January 2012) and requires 20.0w of PoE. The 1250 can support antenna gain > 6 dBi.
The 3500p was released around mid-2011 because people were howling/screaming about the lack of high-gain antenna support, thus the 3500p was developed alongside the AIR-ANT25137NP-R.
Cisco recommends that the installation of the AIR-ANT25137NP-R should be done with proper sight-survey.

WRT54G as Access Point & Intermittent Connectivity

So I followed the advice found here
http://forums.linksys.com/linksys/board/message?board.id=Wireless_Routers&message.id=26177
Hooking up a wired router to my WRT54G Router, which I am trying to use as an access point. I've set my LAN IP to 192.168.1.2, disabled DHCP, cables plugged into LAN ports, not the WAN port.I also changed it to Router Mode instead of gateway mode.
The problem is my wired router is my landlord's, and I don't have access to it. Anyway, I can usually connect, but sometimes it disconnects repeatedly, and it seems like i can't keep a connection for more than 5 minutes.
The problem doesn't seem to nearly as bad when I'm plugged directly into the wall (but there have been a couple times when I've gotten disconnected).
My theory is that I may be getting something mixed up with regards to my assigned IP address. When I'm plugged in i'm 192.168.1.108, but when I connect to the wireless, i'm almost always 192.168.1.100, even though there's only one DHCP server on the network. (this is just a guess, though)
Any advice you can give would be greatly appreciated. THANKS!

I've updated the router's firmware I forgot to mention that in the original post. Are you sure regarding the "gateway mode", the little help blurb on the routers settings says that gateway should only be used when the router is the part of the network that deals directly with the wider internet. I am pretty sure I've tried it in both modes and was having this problem, because it was definately Gateway
