WLC and AP are located at different country

Hi Wireless Expert,

Is it possible to have WLC in one country and AP installed in another country?

Yes, you can configure more than 1 country code on your WLC as needed.

This may help you to see how to do this config on your WLC

To work it properly you should have reliable connection between WLC & AP.

Yes and no.

Yes if both the AP and the WLC are configured with the same Regulatory Domain.

If your WLC has multiple Regulatory Domain configured, only common channels will be enabled.

Hi rasikanayanajith and Leo Laohoo,

So it's possible to install a WLC in Japan and AP install in Singapore? The WLC in Japan able to control the AP in Singapore?

So will the Japan-based WLC also control APs in Japan?  If the answer is yes, then I'd say it will not work efficiently.

So you mean it can be done but less efficient right? Because of distance? or because of the number of AP supported by the WLC?

Ok, let me paint you this picture.

Let's say you have a WLC in Japan.  And you have APs in Japan and in Singapore.

When you configure your WLC to have both APs in the Regulatory Domain, it means that the WLC has to turn OFF channels which are not allowed in both countries.  This only leaves common channels left enable.

If you want to manage APs in different countries, it is best you group APs with the same Regulatory Domain together or you provision separate WLC.

This is not a "Cisco thing".  This is common sense mandated by rules and regulations by the country where the APs are installed.

Thanks for your explanatioo Leo! I am really a newbie in wireless world.

Configuring Country Codes

Controllers and access points are designed for use in many countries  with varying regulatory requirements. The radios within the access  points are assigned to a specific regulatory domain at the factory (such  as -E for Europe), but the country code enables you to specify a  particular country of operation (such as FR for France or ES for Spain).  Configuring a country code ensures that each radio's broadcast  frequency bands, interfaces, channels, and transmit power levels are  compliant with country-specific regulations.

Generally, you configure one country code per controller, the one  matching the physical location of the controller and its access points.  However, controller software release 4.1 or later releases allows you to  configure up to 20 country codes per controller. This multiple-country  support enables you to manage access points in various countries from a  single controller.


Note Although  the controller supports different access points in different regulatory  domains (countries), it requires all radios in a single access point to  be configured for the same regulatory domain. For example, you should  not configure a Cisco 1231 access point's 802.11b/g radio for the US  (-A) regulatory domain and its 802.11a radio for the Great Britain (-E)  regulatory domain. Otherwise, the controller allows only one of the  access point's radios to turn on, depending on which regulatory domain  you selected for the access point on the controller. Therefore, make  sure that the same country code is configured for both of the access  point's radios.


For a complete list of country codes supported per product, see http://tools.cisco.com/cse/prdapp/jsp/externalsearch.do?action=externalsearch&page=EXTERNAL_SEARCH or

http://www.cisco.com/en/US/prod/collateral/wireless/ps5679/ps5861/product_data_sheet0900aecd80537b6a_ps6087_Products_Data_Sheet.html

Guidelines for Configuring Multiple Country Codes

Follow these guidelines when configuring multiple country codes:

When  the multiple-country feature is being used, all controllers that are  going to join the same RF group must be configured with the same set of  countries, configured in the same order.

When  multiple countries are configured and the RRM auto-RF feature is  enabled, the RRM assigns the channels that are derived by performing a  union of the allowed channels per the AP country code. The APs are  assigned channels by the RRM based on their PID country code. APs are  only allowed to use legal frequencies that match their PID country code.  Ensure that your AP's country code is legal in the country that it is  deployed.

The access point can only operate on the channels for the countries that they are designed for.


Note If  an access point was already set to a higher legal power level or is  configured manually, the power level is limited only by the particular  country to which that access point is assigned.


The  country list configured on the RF group leader determines what channels  the members would operate on. This list is independent of what  countries have been configured on the RF group members.

You can configure country codes through the controller GUI or CLI.

Hi Saurav, so a WLC in Japan HQ, it control AP in Japan, the WLC also can control the AP in Singapore branches? I just want to know it can be done and how well is the performance.

Re: WLC and AP are located at different country

Just to add... When I have done numerous wireless country deployments, I would have a dedicated WLC for each region like US, EMEA and APAC. Now depending on the individual countries regulation for channel and power, I would possible have a WLC for each country due to the fact that like everyone mentioned, the WLC will use the most common channels and power levels.

Thanks Scott Fella! So the best practice is to have a WLC for each country for the best performance, am I right?

Bunch your APs to the WLC with the same Regulatory Domain.

For instance, you can have a WLC that manages Australia and New Zeland.  Another WLC that does nothing but Europe.  Another WLC that do US, Canada, Philippines, etc.

Hi everyone,

Any aspect need to consider in this scenario? Such as the firewall?

Thanks and Regards,

Re: WLC and AP are located at different country

You just need to make sure UDP 5256 and UDP 5247 are allowed from the subnets the AP's are in to the management of the WLC.
