Meraki Employee. All forum topics Previous Topic Next Topic. You can also adjust the color-coded signal gauge to your minimum-allowed noise floor level to view areas where the noise floor level exceeds dBm. Grey areas in the floor shown in Figure 12 have noise levels that do not exceed dBm.
Orange and yellow areas have a noise level that exceeds dBm. The RF signal can bleed through from floors above and below. It is important to know how much signal bleeds through the floors because this can cause co-channel interference and can also be the reason why an AP radio operates at a very low power level.
Additionally, this might be the reason why it appears that adjacent APs on the same floor have dynamically chosen the same channel. You can view a map with the AP placements on each floor and verify that the AP placements are not stacked directly above or below the same AP placements on a given floor. AP placements across floors should be staggered to provide better coverage.
You can check the AP radio neighbor list in order to verify bleed through and verify whether you detect APs that are on different floors at a strong signal level. Rogue APs are wireless APs that have been installed on an enterprise network without the authorization of the enterprise information technology department.
Most rogue APs are not installed securely and can be used by outsiders to gain access to an enterprise network. In addition to the security risk posed by these devices, rogue APs are a source of co-channel and adjacent channel RF interference, which degrades the performance of the enterprise WLAN. If there is not a business justification for these APs, they should be disconnected immediately from the network. When disconnected, this improves the overall network security and reduces RF interference with nearby infrastructure APs.
If, however, these Aps do serve a required business function, you should investigate the prospect to integrate the application into the current corporate WLAN infrastructure. A separate walkthrough is normally completed with Spectrum Experts in order to detect and record rogue devices and interferers, which gives you a snapshot of what was detected at that time.
Do not rely only on this report or continuously rely on the infrastructure to detect and report interferers and rogue devices. Rogue devices that are detected by the infrastructure devices should be reported to a management system for further triage and investigation. In order to determine whether the current AP coverage is sufficient for the applications that run on a client, the WLC provides a user-friendly link test tool. The Client Details are displayed as shown in Figure Step 2: Click the Link Test button and run the link test.
This action performs a bi-directional link test that determines the current coverage of the client. If there are no lost packets, then try to move the client away from the AP in order to determine whether there is any additional range available while enough signal is maintained to have quality application performance. When you perform coverage tests on 2. This is a range versus bandwidth design consideration.
Dense 2. The most effective way to reduce channel utilization is to remove lower data rates. Wireless data rate configurations are one of the most critical tools available to tune and optimize wireless networks. The choice of data rate directly impacts coverage and performance; therefore, it is essential to understand how changes to data rates impact an environment.
Lower data rates can be demodulated across greater distances than higher data rates. This is because of the lower complexity encoding schemes — the signal can be understood at a lower SNR. Enable lower data rates in order to increase the effective range of the AP; disable the lower data rates in order to decrease the effective range of the AP.
If you increase the range, this results in greater coverage at the expense of overall throughput. On the other hand, if you decrease the range, this results in better performance and reduces co-channel interference, and effectively decreases channel utilization. For example, if you have voice services in the environment, you are likely to have a higher density deployment and should disable the lower data rates to improve performance guideline for x is 12 Mbps as lowest.
If you have a warehouse with old Version 7. In general, most deployments set the lowest enabled rate as the mandatory rate. High density and multicast environments might have multiple higher mandatory rates. Refer to the Multicast Delivery section in this document for more details.
The primary concern with this is beacon traffic. For example, if one 1 Mbps is defined as mandatory in a dense deployment with six 6 SSIDs, then 67 percent of airtime bandwidth is used on beacons alone. If 12 Mbps is the lowest mandatory rate, then only five 5 percent of airtime is consumed by beacons.
When you disable the lower data rates and limit the number of SSIDs, this reduces time spent on management traffic and allows for more bandwidth for the connected clients. There is an exception if there are current associated clients that transmit at a rate lower than the highest mandatory rate. For example, the highest mandatory rate is 24 Mbps and lowest mandatory is set to six 6 Mbps.
But, if any one client rate shifts down to six 6 Mbps, then the transmission occurs at six 6 Mbps. Otherwise that client cannot receive it. Change the mandatory rates in order to modify multicast performance. When you set high mandatory rates, this allows higher bandwidth multicast streams to be delivered, although all clients might not receive the stream very reliably.
If you set lower mandatory rates, this allows the stream to be delivered to lower signal strength clients at the expense of bandwidth performance. It allows you to track received signal strength with the wireless adapter that is already installed. Note: inSSIDer is not a full solution for wireless packet and spectrum analysis. The various filters that you can apply are located at the top of the screen.
Filter on the SSID that you want to measure to avoid any incorrect results from nearby rogue wireless networks. For best scanning performance, be sure to connect your workstation to the SSID you want to verify. This ensures faster processing of Beacon and Probe Responses. Remember, for voice services, the goal is to have at least two 2 APs heard at dBm or greater at all times. In this example, voice services fail in this environment, as there is only one 1 signal strength greater than dBm with the assumption of a noise floor of dB, which allows for a SNR of 25 dBm.
You can verify whether the signal strength varies over time in your environment, if you suspect any RF issues caused by environmental changes. The connected AP is highlighted in red. Divide the value reported in CU by to achieve a channel utilization percent.

Passive Survey Passive surveys are surveys that are performed with a listen-only mode. These can be accomplished with a passive survey: Identify rogues Locate RF trouble zones quickly Validate final RF setting Perform initial surveys The most significant loss of information with passive surveys is uplink information, Physical PHY rate boundaries and retransmission.
Active Survey Active surveys are performed with the survey client associated to the APs used throughout the survey. Predictive Surveys Predictive surveys are performed with a software program. The best times to incorporate a predictive survey include: When the deployment environment has not yet been built.
In order to obtain a budgetary environment for WLAN-related hardware. When roaming requirements are less stringent. Prepare for the Survey Use this checklist to help you prepare your survey. Identify Primary Requirements: RF application needs voice, data, location, etc. Tools to be used in order to complete the survey, such as Airmagnet, Ekahau, and so on.
Active or passive survey. Auto sampling. Type of adapter to be used to perform the survey. Spectrum Analysis screenshots and recordings of possible sources of interference. Identify and list possible sources of interference. A walkthrough should be performed through the facility.
Ask about and look for possible sources of interference, such as microwave ovens, cordless phones, and so on. The AP hardware to be used. The AP should be selected to match the AP that is planned to be purchased and deployed. Three is quicker than one, but the AP placements might be sub-optimal. Identify the type of survey to be conducted: voice, location, or data only. Mistakes That Make a Survey Poor Mistakes can be made with the use of survey tools that are able to make a site survey report look good.
Calibration The map calibration in a survey tool allows you to define the correct distance between two points on the map. Figure 1: Improperly-scaled Map with default dimensions of feet by feet Figure 2: Properly Calibrated Map You should always verify the map calibration. Figure 4: Signal Propagation should be changed from the defaults Survey Path It is important to verify the survey path on which the data points were taken.
Incomplete Walking Path Data points were not taken in all locations; this includes inside the offices along the bottom of the floorplan. Figure 5: Incomplete Walking Path Complete Walking Path Data points were captured inside the offices along the bottom of the floorplan.
Figure 6: Complete Walking Path Considerations for Capacity For areas such as conference rooms, which might have high client density, it is important to consider client capacity needs as well as coverage. Key Items to Check in a Post-validation Survey The primary objective of a post-validation site survey is to provide detailed information that addresses the current RF coverage and determines whether there is sufficient coverage to support the network design requirements.
Coverage Coverage defines the ability of wireless clients to connect to a wireless AP with a signal strength and quality high enough to overcome the effects of RF interference. Figure 8: Signal at dBm When you check the signal coverage, make sure the AP's radio transmit power does not use a transmit power greater than what the client devices can support. Rogues and Interferers Rogue APs are wireless APs that have been installed on an enterprise network without the authorization of the enterprise information technology department.
