Aironet 1500 series point to point connection

Hello, I have a question for cisco Aironet 1500 series. I want to connect two of them as point to point in a distance about 6 km (kilometers). So there are two questions, can them be connected as point to point to transmit signal and the second one what is the max distance of AP to be connected.
Kind regards,
Ardit

There are a lot of factors when it comes to an outdoor bridge connection. What kind of traffic is going to pass over that link? How much bandwidth do you need? Is there an free line of sight and can you place the (high gain) external antennas somewhere high or maybe even in an tower? And what about the factors you can't influence like the weather?
I personally don't have experience with this kind of high distances, but if you are going to do an test I would advise to go for the 1570 bridges and select an high gain antenna. A good starting-point for outdoor point-to-point connections is Cisco's WNG Coverage Capacity Calculator. You can also use tis tool to calcuate your Effective Isotropic Radiated Power, which should not exceed the rules dictated by your regulatory domain.

Need Help with extending Airport Extreme w/802.11n

I would like to find a way, if there is one, to extend the coverage of my Airport Extreme w/802.11n. My object is to be able to share my home network with a 2nd house on my property which is approx. 90-100' away from main house and Airport Extreme w/802.11n base station. This home base station is connected to my iMac and I would like to extend it to allow my Dell PC w/ Win XP in 2nd house to connect to the internet/share files/share printer.
Is this possible and what would I need on the PC side to accomplish this wirelessly?
Thank You in advance for your help.
Daniel

Is the 2nd house on a the same electrical box as the main house? If it's the same, then you can try the powerline ethernet solution.

You will find it cheaper than most outdoor point-to-point bridge solutions.

Cisco 1200 on long distances

I need to know (if anyone have in practice). What will be maximal distance in ideal conditions with Cisco 1200 series AP for outdoor point-to-point connections in WGB mode with high gain directional antennas ?

Console into the AP and post the log. This will help understand the issue better.

EAP Recommendation

Hi All,
I recently received the duty to design and configure the access security and encription for a series of outdoor point to (multi)point links.
Previously we used non-Cisco equipment with MAC authentification for access control with WEP 128 bits RC4 algorithms for encription.
However, it seems that newer equipment (besides being faster) has much better intrusion protection.
I would like to know what could be recommended anti-hackers protection for Cisco Aironet 1310G equipment.
From what I have seen, Cisco can use LEAP or PEAP for access control. Can the LEAP be secure enough with a strong password, or is better to avoid? And can the PEAP be configured with what comes from the box, or external services are requerired? And can one of the 1310G or perhaps a Cisco router operate efficently as RADIUS server for EAP authentification?
Also, I would like to know of what could be the recommmended encription methods, available in the WPA2 Aironet 1310G's.
Thanks in advance for any information and recommendations.
Regards,
Igor Sotelo.

For PEAP, you need Windows XP service pack 1(atleast) to be able to use Windows PEAP. Plus I guess you need Certification server to download certificates to root directory of laptops.
LEAP is much easier than PEAP in terms of use, but PEAP is much more secured than LEAP. Please read some other postings regarding PEAP for PEAP drawbacks.
WPA2 uses AES encryption which is the most secured encryption mechanism.

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 ?

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.

Cisco 1524 Aironet Outdoor Wi Fi Access Points

I am using Cisco 1524 Aironet Outdoor Wi Fi Access Points for outdoor Wi-Fi Coverage with WiSM Controller. I want to cascade Bridge them with UTP/STP Cables instead of using MESH using the Ethernet Bridging Function inside the controller. But I cannot have a cascaded Bridge chain of more than 2 AP's. Can
anybody advice & help me in this scenario?

Hello Mohammed,

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.

Typical propagation distance of outdoor(1552E series) access point

Hello All,
I need to propose an design for outdoor WAP deployment for an huge resort. As it is a complete open space area without any obstruction, I believe the signal can be propagated easily in over 35 meters radius across the access point. However I don't get any documentation to know exact propagation distance.
Could someone please share their experiences as to what is the ideal distance of signal coverage that could be covered by a typical Cisco outdoor access point? I do not want to go for over quoting as that might result from the client opting for other vendor's product. I would thus want to go with most appropriate plan.
Also apart from 11ac capability and multiple spatial streams, does 1570 AP have any other major improvement as well our its predecessor 1552E series AP.
Please share your expereinces.
Best Regards,
Muhammed Adnan

Factors Affecting Wireless Networking Performance
There are many factors that affect your Wireless Networking Performance that are dependent on various areas within the network itself from the technology of the devices used, the local environment the signals will travel through, the fundamental physics behind wireless transmission and more. Some of these cannot be avoided and measures must be taken to try to minimise the negative affect that these factors will have on the network performance but others can be resolved completely either though equipment upgrading or good network planning.
There are some well known factors that affect Wireless Networking performance that most people will identify easily but that does not lessen their importance when considering network planning, these are:
Obvious Factors Affecting Wireless Networking Performance
    Physical Obstructions
    Network Range & Distance between Devices
    Wireless Network Interference
    Signal Sharing
Quite Well Known Factors Affecting Wireless Networking Performance
    Network Usage & Load
    Poorly Deployed Antennas
    Local Environment Characteristics
    Spectrum Channel Limitations
    Signal Reflection
    Wireless Signal Restriction
Lesser Known Factors Affecting Wireless Networking Performance
    Transmitter Power Limitations
    Backwards Compatibility with Older Standards
    Polarisation of Signal
    Speed Loss Due to Wireless Overheads
    Lowering Performance to Stay Connected

3502p AccessPoint support MESH and Point-to-Point Wireless Bridging with Outdoor Antennas??

I need to know if 3502p with outdoor antennas supports Point-to-Point Wireless Bridging??

The 3502p is only used for arenas and or stadiums. These are different units than the 3500's and 3600's. So no they can't be.
You can use Cisco Aironet 1400 Series Wireless Bridge for a wireless link between two buildings (1km) to extend your LAN. For more detail you can go through the below link.

Outdoor WiFi Point-to-Multipoint Root redundancy

Hello,
In an outdoor wifi setup connecting main site to remote sites through point-to-multipoint design, if the main building AP root bridge fails, all the remote sites will be out of network. How shall we achieve redundancy in case of the main site failure?
I have a possibility of another building (second main building) with wired medium to split the entire wireless domain, in which I can install a new root bridge catering 50% remote sites. The first 50% sites will be connected to Main site 1 root bridge and rest 50% to Main site 2.
Is this a valid design?
Is it possible to fall back non-root AP from Main site 1 root to secondary site root?
Can a non-bridge AP fall back to another Root bridge?
Or any other valid design to achieve root level redundancy?
The total campus coverage area is 2 km.
Thanks in advance!
Kumar

Increasing Mesh Availability
A wireless mesh cell has similar properties to the cells used to create a cellular phone network. The technology may define the maximum size of the cell; smaller cells can be created to cover the same physical area, providing greater availability or capacity. This is done by adding RAPs to the cell. Just as in the larger mesh deployment, the decision is whether to use RAPs on the same channel, as shown in Figure 8-16, or use different channels, as shown in Figure 8-17. The addition of RAPs into an area adds capacity and resilience to that area.
Figure 8-16 Two RAPs per Cell with the Same Channel
Figure 8-17 Two RAPs per Cell on Different Channels
Multiple RAPs
Before deploying multiple RAPs, the purpose for deploying these RAPs needs to be considered. If additional RAPs are being considered to provide hardware diversity, they should be deployed on the same channel as the primary RAP. The reason for this is to minimize the convergence time in a scenario where the mesh transfers from one RAP to another. When planning RAP hardware diversity, the 32 MAPs per RAP limitation should be remembered.
If the additional RAPs are being deployed primarily to provide additional capacity, the additional RAPs should be deployed on a different channel from its neighboring RAPs to minimize the interference on the backhaul channels.
When adding a second RAP on a different channel, channel planning or RAP cell splitting can be used to reduce the extent of potential collision domains. Channel planning allocates different non-overlapping channels to RAPs in the same collision domain to minimize the collision probability. RAP cell splitting is a simple, yet effective, way to reduce the collision domain. Instead of deploying one RAP with omni-directional antennas in a mesh network, two or more RAPs with directional antennas can be deployed. These RAPs are collocated but operate on different frequency channels, thus dividing a large collision domain into several smaller ones that operate independently.
If the Wireless Mesh bridging features are being used with multiple RAPs, these RAPs should all be on the same subnet to ensure that a consistent subnet is provided for bridge clients.
If you build your mesh with multiple RAPs on different subnets, MAP convergence times can increase in the event of a fail over as the MAP has to failover to another RAP on a different subnet and DHCP for an appropriate IP address. One way to limit this from happening is to use different BGN for segments in your network that are separated by subnet boundaries. In segmenting in this manner, MAPs do not associate with a RAP on a different subnet and you avoid slow convergence issues and the expense of the higher availability offered by the additional RAPs.
Hope that helps.

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.

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..
