Cisco Aironet 1520 Series Mesh Access Points

---

This chapter lists the 1520 series mesh access point IEEE 802.11b/g (2.4-GHz) and IEEE 802.11a (5-GHz) channels and the maximum power levels supported by the world's regulatory domains. For additional product hardware information refer to the Cisco Aironet 1520 Series Outdoor Mesh Access Point Hardware Installation Guide.

The AIR-LAP1522 access point model supports both 802.11b/g and 802.11a radios. The AIR-LAP1521 access point model only supports a 802.11b/g radio.

The following topics are covered in this chapter:

•Channels and Maximum Power Levels

•Changing the Lightweight Access Point Output Power

Channels and Maximum Power Levels

AIR-LAP1521G

IEEE 802.11b/g (2.4-GHz Band)

When shipped from the factory, the AIR-LAP1521G single radio access points support the channels and maximum power levels listed in Table 9-1 for their regulatory domains with up to 5.5 dBi antennas.

---

Note In Table 9-1 and Table 9-2, the operating data rates (in Mbps) are shown in the CCK and OFDM table cells. For example: CCK 1-11 indicates CCK data rates of 1 to 11 Mbps and All indicates all CCK and OFDM data rates.

Minimum 5-GHz Radio Power Levels

Table 9-8 lists the minimum power levels supported by the 5-GHz radio for the various channels and regulatory domains.

---

Note When the minimum radio power level is reached with a controller power setting (1 to 5), changing the controller power setting to a lower value does not result in a lower radio output power level. For example, if the minimum radio power level corresponds to controller level 3, then levels 4 and 5 also correspond to the same power level.

Special Country Restrictions

Table 9-9 lists special restrictions for wireless operation in some countries.

Table 9-9 Special Country Restrictions for Wireless Operation

Country	Frequency Band (GHz)	Regulatory Domain	Special Limitation and Restrictions
Australia	5	-N	5 GHz maximum antenna gain limited to 8 dBi.
Mexico	2.4	-N	End user must limit 2.4 GHz operation to 2450 to 2483.5 MHz and 36 dBm EIRP1 .
New Zealand	5	-N	5 GHz maximum antenna gain limited to 8 dBi.
United States	4.9	-A	The use of the 4.9-GHz band requires a license and may be used only by qualified public safety operators as defined in section 90.20 of the FCC rules.

1 EIRP (dBm) = maximum output power (dBm) + antenna gain (dBi)

Changing the Lightweight Access Point Output Power

This section provides instructions for changing the 1520 series access point output power to comply with the maximum power limits imposed by special regulatory and country restrictions (see the "Minimum 5-GHz Radio Power Levels" section). Follow these instructions to change the output power settings using a controller and your browser:

---

Note Administrator privileges may be required in order to change access point settings.

---

---

Caution To meet regulatory restrictions, the access point and the external antenna must be professionally installed. The network administration or other IT professional responsible for installing and configuring the unit is a suitable professional installer. Following installation, access to the unit should be
password-protected by the network administrator to maintain regulatory compliance.

---

The output power on the 1520 series access points can be changed only by using a Cisco wireless LAN controller (2600 series or 4400 series), the controllers on a Cisco Wireless Services Module (WiSM), or using Cisco Wireless Control System (WCS).

---

Note See the Cisco Wireless LAN Controller Configuration Guide for more details on how to to configure your access point using the web-browser interface.

---

Follow these steps to change the 1520 series access point's output power to meet local regulations using a controller:

---

Step 1 Open your Internet browser. You must use Microsoft Internet Explorer 6.0.2800 or a later release.

Step 2 Enter https://IP address (where IP address is the controller's IP address) in the browser address line and press Enter. A user login screen appears.

Step 3 Enter the username and password and press Enter. The controller's summary page appears.

---

Note The username and password are case-sensitive.

---

Step 4 Click Wireless and choose 802.11a/n or 802.11b/g/n under Access Points / Radios . A list of associated access points appears.

Step 5 Choose the desired access point from the displayed list and click Configure from the drop down arrow. The the radio configuration page appears.

Step 6 Scroll to the Tx Power Level Assignment field, and click Custom.

Custom indicates that the radio output power is manually controlled by the Tx Power Configuration setting field.

Step 7 In the Tx Power Level field, select the appropriate power level setting (1 to 5).

Based on the operating channel, the regulatory domain, and the controller power level setting (1 to 5), the actual transmit power at the access point can be reduced to comply with special regulatory or country restrictions.

---

Note Table 9-1 and Table 9-5 list the access point maximum output power levels supported for each regulatory domain when the access point is shipped from the factory.

---

Table 9-10 lists the controller power settings and the corresponding output power levels for these two examples:

•2.4-GHz (802.11b/g) operation:

–The -E regulatory domain.

–Channel 3 using 11-Mbps data rates

–8 dBi antennas

•5-GHz (802.11a) operation:

–The -A regulatory domain

–Channel 149 using 48-Mbps data rates

–17 dBi antennas

Table 9-10 Example of Output Power Levels

Controller Tx Power Settings1	Radio Output Power
	802.11b/g (dBm)	802.11a (dBm)
1 (maximum)	142	253
2	11	22
3	8	19
4	5	16
5	2	164

1 The Tx Power Level setting of 1 represents the maximum conducted power setting for the access point. Each subsequent controller power level (such as 2, 3, 4, etc.) represents an approximate 3-dBm reduction in transmit power from the previous power level. 2 The maximum output power level obtained from Table 9-1. 3 The maximum output power level obtained from Table 9-5. 4 The minimum radio output power level obtained from Table 9-8

•For this example with 8 dBi antennas, the maximum power allowed for the 2.4-GHz radio is
12 dBi from Table 9-4. This corresponds to a maximum controller power setting of level 2.

•For this example with 17 dBi antennas, the maximum power (Table 9-7) allowed for the 5-GHz radio is 24 dBi, which corresponds to a maximum controller power setting of level 1.

Step 8 Click Apply.

Step 9 Close your Internet browser.
