Cisco Aironet Series 702W Access Point Deployment Guide

Last Updated: August, 2014


This document covers the Cisco 702W Series Access Points theory of operation and installation as part of a Cisco Wireless LAN (WLAN) solution. Subjects related include:

  • Overview of the AP-702W.
  • Physicals / Hardware details, mounting options, bracket choices, and installation considerations.
  • Powering options, antenna patterns, switched ports, AP placement, and so on.

This document is intended for trained and experienced technical personnel familiar with the existing Cisco Wireless Networking Group (WNG) product line and features.



The Cisco AP-702W Series Access Point targets Multi-Dwelling-Unit (MDU) deployments, such as customers requiring support for Higher Education, Hospitality, college dorm-rooms, K-12 classrooms, and healthcare, seeking a high-performance in-room Wireless + Wired Access Device.

The AP-702W is a wall plate Access Point (AP) designed to combine the features of an AP and a four port switch into a single unit with a small footprint targeting education and hospitality markets.

NoteDo not confuse AP-702W with AP-702i, which is a conventional AP designed for ceiling mounting and does not have additional Ethernet ports for device connectivity.

AP-702W Features Include

  • Combined hardware switch and wireless AP.
  • 4 x 10/100/1000BASE-T local Ethernet ports for wired device connectivity.
  • 1 local Ethernet port includes Power-Over-Ethernet (PoE) out.
  • 1 x 10/100/1000BASE-T Power-Over-Ethernet (PoE) uplink port.
  • 802.11n 2x2:2 simultaneous dual band 2.4 GHz and 5 GHz support.
  • Compact form factor designed for in-room installations.
  • Integrated 2.4 GHz 2 dBi and 5 GHz 4 dBi antennas.
  • Small footprint 6 x 4 x 1.6 inches.

The AP-702W, while similar to the Cisco AP-700 series with regards to performance, is different and embodies a wall mount design and should not be ceiling mounted.

Figure 1 Unit can be installed in less than a minute with a simple screwdriver.

A sticker covers the #6 Torx screw to prevent detection. Also, a Kensington lock may be used as well.

AP-702W Installation

As mentioned in Figure 1, the AP-702W is designed to be mounted on an existing electrical box or network outlet box. Because of the vent holes on the device, it is not designed for ceiling mounting but may be mounted on the wall close to the ceiling so long as there is at least a 3-inch gap between the top of the unit and the ceiling for heat dissipation.

The default wall bracket is designed to allow the four switched ports to be accessible for downstream devices. It is not recommended (or supported) to use the downstream switched ports to connect additional APs or other heavy upstream traffic devices such as additional switches and so on.

The Ethernet ports in AP-702W are disabled by default and can be enabled by using the
enable_port port id command, where port ID can range from 1 - 4.

NoteBy default, the 4 switched ports on the AP are disabled.

Figure 6 Optional AIR-AP-BRACKET-WP can be used to secure the four switched ports

Figure 7 Physical Dimensions for the AP-702W Bracket in Millimeter

AP-702W Powering Options

The AP-702W is designed to accept power via Power over Ethernet (PoE) or by using a local “brick” style power supply. Because the AP-702W has the ability to provide PoE out on port #4, the unit draws in an excess of 15.4 Watts (802.3af) specification, and therefore it is recommended that PoE+, 802.3at, or local power supply Cisco part number AIR-PWR-C be used.

When the AP is first powered on, if powered via Power over Ethernet (PoE) it will negotiate power using the Cisco Discovery Protocol (CDP) and/or Link Layer Discovery Protocol (LLDP). By using these methods, the AP-702W will ask for 15.4 W initially starting up with that amount of power. During the Power On Self Test (POST) it will discover that it has a port on PSE LAN4 capable of producing PoE out, so it will then attempt to negotiate for additional Ethernet power via the same methods for that port. If additional power is available, it will switch from 802.3af (15.4 W power) to PoE Plus / 802.3at power. The amount of power it negotiates varies with the version of code being used.

If the code version is 7.6, it will request 30 W. If the code version is 8.x, it will request 22.1 W. If the AP is successful in negotiating the higher PoE power from an 802.3at or PoE+ source, the AP-702W will then come up and allow the PSE LAN4 port to provide Class 2 PoE out at 6.49 W (7W with cable losses).

If the AP is not successful in negotiating the higher PoE power value from 802.3at or PoE+, it will continue to use 15.4 W (802.3af) power and continue with PoE out on the PSE LAN4 port disabled.

Note At this time there is no method of disabling the “ask” for additional power if high power is present. There is a feature request to better handle this in the future, but if the goal is to have the AP-702W not ask for additional power, then a work around would be to configure the powering device to only allocate 15.4 W (802.3af) power on the port that the AP-702W is attached.

1.This is the power required at the PSE, which is a switch or injector.

2.In the 7.6 version code, the draw is 30 W and in the 8.0 code, the draw is now reduced to 22.1 W.

Local power supply AIR-PWR-C= may be used. Do not use AIR-PWR-B.

Note If PoE+ or 802.3at power source is present, the AP will negotiate higher power. If this is not desired, a work around is to limit PoE on switch to 15.4 W until addressed in release 8.1.

Note If the unit is powered by 802.3at (PoE+) then the device can deliver PoE out of port 4 at 7 W output. If 802.3af (15.4 W) is desired out of Port 4, then the local power supply AIR-PWR-C must be used.

Earlier Cisco-Aironet power supplies are rated at 48 VDC @ 380 mA. These earlier supplies do not have enough current to allow the AP-702W to provide PoE out on port 4.

AP-702W Antenna System

The AP-702W has two integrated dual band antennas designed for best performance when mounted to an electrical box in a wall mount configuration.

Figure 9 Antenna 1 and Antenna 2 mounted on the Top and Left Side of the AP-702W

Avoid mounting the AP in locations where metal objects would be near the antennas.

The antenna gain is 2 dBi @ 2.4 GHz and 4 dBi @ 5 GHz designed to radiate in a front Omni-directional pattern with 25 dB of isolation between bands.

As mentioned, the AP-702W is designed for wall mounting and so it may have a slightly smaller cell coverage area than a conventional AP that is typically mounted physically higher on a ceiling. This is fine, because Cisco Radio Resource Management (RRM) will learn and properly balance out the channel assignments, and clients will roam smoothly when there is a mixture of ceiling and wall mounted APs.

Figure 12 Heat Map - AP-702W and AP-3700

Figure 13 Channel Assignments and Power Settings Determined by Cisco RRM

Roaming, channel assignments, and RF power all function well with the AP-702W. Its antenna technology comprising two transmit radios and two receive radios in each band called 2x2 in a Multiple Input Multiple Output (MIMO) configuration support two spatial streams (2SS) together referenced as 2x2:2. For more on the benefits of 802.11n, see the following URL:

AP 702W Switched Ports

Figure 14 Ethernet Switched Ports AP-702W

The 4 x 10/100/1000BASE-T local Ethernet ports support half and full duplex mode, auto-negotiation, and MDI/MDIX Auto-Sensing. Devices you connect must support auto-negotiation if you connect with another mode, for example—hard configured speed and so on. The port may not be enabled, and in some cases the ports are not managed, depending on the version of code, for example (the initial release).

Note VLAN support is available in release 8.0. See Configuring VLANs in Release 8.0 at the end of this guide for details.

For now, (until more control is added in the software) all the LAN ports are locally switched and mapped to the 702W VLAN, and do not appear on the Wireless LAN Controller or AP.

Initially, the ports are disabled and may be enabled manually via the CLI.

This was done to minimize any security risks. Here are the CLI commands to enable the ports.

(Cisco Controller)> config ap lan <port id> <enable/disable> <AP-NAME>

(Cisco Controller)> show ap lan <port id> <AP-NAME>

(Cisco Controller)> show ap lan port-summary <AP-NAME>

Due to the early release of the code, the enable/disable all command was not integrated, so you must configure each AP and each port, one by one. With code 8.0 and later, a more refined control along with VLAN support is being added to these ports.

When configuring the AP-702W for PoE out on port 4, it is important to verify that you have at least 16.1 W when powering the unit by PoE. So, the AP will require PoE+ or higher power than what can be provided by 802.3af (15.4 W).

To troubleshoot PoE, check the PoE status under the Wireless > Advanced tab and verify if the power is higher than medium (15.4 W).

Figure 15 PoE out on Port 4 will not happen if PoE Status is only Medium Power (15.4 W)

Figure 16 Verifying FULL Power on the Controller

The PoE needs to be at full power. You can use PoE+, 802.3at, local power supply, or Cisco Power Injector 4 Cisco part number AIR-PWR-INJ4 which provides higher PoE power. The AP-702W will not be able to provide PoE out if a 15.4 W injector, such as the AIR-PWR-INJ5 or 802.3af power, is used.

For more on PoE, see Table 1 .

Tips for Wireless Installations

1. It is all about placing the AP as reasonably close to the actual users as possible.

2. Make sure that you have coverage, (to a known requirement) and compensate for nulls or dead spots regardless of what product you choose to deploy. This is called a site survey.

3. Installations should be done based on lessons learned from the site survey, the better the survey the less likely connectivity problems will occur.

4. Cisco has an advanced services team that can perform WLAN surveys or help with the wireless design if a partner is not available or able to do the same.

5. Do not mount antennas against metal objects. Similar to a light bulb, antennas work best when there are no obstructions in the path.

AP-702W AP Spacing Recommendations

If you have a Wi-Fi device such as an AP and you are going to use another AP in the vicinity on a different channel, it is recommended that you space each AP apart by approximately 6 feet (2 meters). Avoid clustering the APs or the antennas from different APs together because this could cause degradation in performance. The recommended distance is based on the assumption that both devices operate in the unlicensed band and do not transmit RF energy more than 23 dB, that is, 200 mW. If higher power is used, space the devices farther apart.

Should you have other devices that transmit, especially if they operate in the same frequency ranges, for example, frequency hopping legacy APs or other devices that operate with close frequency to those of the APs (think below or above the 2.4 and 5 GHz band), you should consider moving or separating the devices as far apart as can reasonably be done. After you have done this, check for interference by testing both devices at the same time under heavy utilization (load) and then characterize each system independently to see how much, if any, degradation exists.

Warning In order to comply with FCC, EU, and EFTA RF exposure limits, antennas should be located at a minimum of 7.9 inches (20 cm) or more from the body of all persons. See the installation guide under declaration of conformity for more on this.

Installations in IDF Closets (Telecommunications or other Electrical Equipment)

When installing APs near other electrical or telecommunications equipment, keep all wiring and metal away from the antennas and avoid placing the antennas near electrical lines. Do not route wiring electrical or Ethernet in the near field (6-15 inches) of the antenna. Try to refrain from installing the AP in the electrical closet because the best place for the AP is as close to the users as possible/practical. If you have remote antenna cables from in a closet, you may be required to use Plenum rated cable (see local fire/safety regulations for more on this).

Below are a few URLs for understanding interference:

Site Survey Considerations

It is considered a good practice to conduct a site survey to assess cell coverage and look for problem areas such as poor RF coverage or high retries. Always try to install the AP as close to the actual users as possible or practical to do so.

If you have done a site survey with a previous product, chances are that the survey is still valid and you only need to perform simple checks to verify that coverage holes or problem areas do not exist.

Figure 18 Heat Maps and coverage areas are fairly uniform between different APs

While cell sizes are similar, each higher end AP model employs methods that allow the user to experience higher data rate connectivity with less retries. For example, using higher MCS rates, Spatial streams, or Cisco’s ClientLink beam-forming technology. So, the take away is that the client experiences a higher performance and faster connectivity, but it is not designed to change the actual cellular coverage area so surveys maintain their validity across different AP models.

Configuring VLANs in Release 8.0

Configuring VLANs on the Network

Overview of the Network

The AP 702W uplink port connected to the controller must be set to trunk. The AP will set its IP address (and therefore its management interface) in the untagged / native VLAN. The AP VLAN is assigned by setting the right native VLAN on the trunk.

Client traffic can be assigned to different VLANs by assigning these VLANs on the AP 702W's trunk port and then configuring the 4 Ethernet ports specifying the VLAN per port on the Wireless controller software AP configuration.

Wired client traffic will be locally switched on the AP port. Wireless traffic and CAPWAP traffic will be sent to the controller. Once this is done, then enabling access on the 702W AP is done.

Configuring VLANs on AP 702W

From code release onward, you can configure LAN ports and VLAN assignments.

Before setting VLANs, enable the LED state on the 702W AP, so you can confirm whether the client is connected because the ports and LEDs are in disabled state by default.

To enable the LED state from the CLI, use the command: config ap led-state enable

See the following screen shot to enable the LED state from the GUI:

Once the LEDs are enabled, connect a client to one of the ports (1 - 4) on the 702W. The Green LED on the 702W should be off because the ports are not yet enabled. Once the ports are enabled, the Green light will turn on.

The GUI allows you to enable the ports and setup VLANs. In this example, VLAN 71 and 70 are enabled on ports 1 and 2, respectively.

In the following example, VLAN is not defined on port 3 (so it will default to the native VLAN) and port 4 is disabled.

Now, verify if the client is able to receive an IP on each of the different VLANs. You should be able to do an IP config release and renew, and physically move the client across ports 1-3 (verifying the different VLANs and confirming that port 4 remains disabled). At this point, the ports that are enabled should work.

Additionally, the following CLIs can be used instead of the GUI.

Commands via the CLI

CLI commands apply only for the 702W AP. For other APs, it is displayed as “Not supported”. The following CLIs commands are supported for LAN port configuration:

1. To enable access VLAN on a particular LAN port:

config ap lan enable access vlan <vlan id> <port id> <AP-NAME> // vlan id (2 - 4094), port id (1 - 4)

Note On enabling access VLAN, vlan_valid in the lan_port info structure will be set to TRUE and vlan_id will be populated. VLAN IDs 1 and 4095 on LAN ports are not supported.

Note If a connected wired client on the LAN port needs to send untagged packets out on the WAN port, then VLAN must not be configured on that port.

2. To disable access VLAN on a particular LAN port:

config ap lan disable access vlan <port id> <AP-NAME> // port id (1 - 4)

Note On disabling access VLAN, vlan_valid in the lan_port info structure will be set to FLASE and vlan_id will be set to 0. When VLAN is disabled on a port, it sends untagged packets towards WAN and internal AP software.

3. To enable or disable a particular LAN port:

config ap lan port-id <port id> <enable/disable> <AP-NAME> // port id (1 - 4)

4. To display the configured values for a particular LAN port:

show ap lan <port id> <AP-NAME> // port id (1 - 4)

5. To display the configured values for all the LAN port:

show ap lan port-summary <AP-NAME>

General Considerations Regarding APs

Following are some guidelines to remember regarding all APs.

1. Always try to mount the AP as close to the users as possible for best performance. Be aware of the environment; for example, hospitals have metal doors and the coverage can change when the doors close or old buildings can have metal grid work in the plaster or asbestos. Avoid mounting the AP or antennas near metal objects because doing so can change the coverage area.

2. When using the 2.4 GHz frequency, the same 1, 6, and 11 channel scheme is used as is the 5 GHz channel scheme. Avoid putting all the APs on the same channel, and reuse channels as you can. See our other deployment guides for more on this topic.

Figure 19 Example of Channel Usage in 2.4 and 5 GHz (Two channels used if 40 MHz)

3. Try to determine which clients are going to be used and check the coverage using those clients. For example, a PDA or Wi-Fi phone might not have the same range as a notebook or tablet.

Tip Verify coverage using the worst performing clients that you intend to deploy.

4. While site surveys are generally recommended, if the design is done at half power and Cisco RRM is in place, sometimes a limited site survey (coverage check) is adequate for smaller venues. If this is a very challenging environment such as train connectivity, Gas and Oil verticals, large hospitals, and so on, Cisco has an Advanced Services team that can be contracted to help you get up to speed or perform your installation. See your Cisco account team for more information.

5. The rule of thumb coverage plan is: 1 AP per 2500 square feet.

6. Some clients (especially older ones) do not support the UNII-2 extended client channels 100-140. So, if you have a lot of older clients you may want to disable them in the DCA channel list.

NoteMore and more clients support these channels all the time, as will the newer 802.11ac clients.

Questions and Answers

Q. Which AP is best for Hospitality, dorm rooms, and smaller venues?

The AP-702W.

Q. Which AP is best for manufacturing and warehouse areas?

Generally speaking the AP 3700e, 3600e, or 2700e would be the first choices because these external antenna models have the highest operating temperature range, -20 to 55C. The AP-1600 can also be used but it has a slightly lower operating temperature, -20 to 50C. If temperature is not a concern then the internal antenna “I” series 1600, 2600, and 3600 may be used.

Q. What if I am in a country where the regulatory agency may not approve the AP to be used outdoors because of UNII-1 band restrictions? Or I wish to use higher gain antennas?

Consider deploying the Cisco Mesh products (1550 and 1530 series) or look for APs ending in “P” for professional install, such as the 3702P series or our outdoor bridging products.

Q. Which AP is best for high density deployments?

Both the 3700 and 2700 have virtually identical AP density for coverage based design. Capacity-based designed (smaller-cells).

Q. Cisco has a newer Power Injector (AIR-PWR-INJ5). How is this different from the AIR-PWR-INJ4?

The newer AIR-PWR-INJ5 is a low-cost injector for use with 702i, 1600 and 2600 Series Access Points products. It is a 802.3af (15.4 W) injector. The AIR-PWR-INJ4 is a more powerful injector designed to work with the AP-702W, AP-3700, and AP-2700. The AIR-PWR-INJ5 can be used with the AP-702W but not if the PoE output port #4 is required.

Q. Can industrial wireless motion or smoke detectors cause WLAN interference?

Yes, some products such as United Technologies DD475 and Optex MX-50 operate in the 2.4 GHz band as do other wireless “chimes”, cameras, and other industrial equipment from other manufacturers.
