The Samsung Wireless Enterprise Manager (WEM) product provides a comprehensive set of tools to manage Samsung Wi-Fi infrastructure. The WEM acts as a Network Management System that provides the following features:

  • Monitoring
  • Configuration
  • Operation
  • Troubleshooting
  • Reporting
  • Historical Statistics

The Dashboard

The Dashboard allows a network administrator to view the overall wireless network health. It supports a number of customizable options for the widgets. Statistics like overall network bandwidth usage over time, top talkers, and inventory status make it easier to manage a larger network. Most of the stats are updated every 30 seconds.

Alarming & Alerting

Real time alarming allows for a proactive approach to solving wireless issues. The Event Viewer updates the alarms in real time for operations team monitoring. This, coupled with alerts which can be sent via email to a support group or the IT admin, makes it possible to stay on top of the issues. Alerting can be customized so that the system is not sending too many updates. For instance, instead of sending an alert for every AP, the system can be customized to send an alert when a bunch of APs go down, indicating a larger network issue like a core switch going down. Thresholds can be set up to report an issue when a certain area is experiencing poor wireless performance either on the 2.4 GHz or the 5 GHz band. This may point to an issue with an underlying interferer or higher channel utilization.

AP & Station Statistics

WEM offers an easy way to find a particular station and then drill down into the statistics per station. It gives station characteristics like the data rate/SNR/RSSI over time.  These stats help an administrator understand the RF conditions at any given time.


RF Maps

The hierarchy for the maps begins with a site view, for example the “XYZ Enterprise”. You then drill down to the location view, for example “XYZ Enterprise Dallas Location” and then a building view, “XYZ Enterprise Dallas Location Building 1”. Floor maps can be imported as an image and then scaled accordingly. APs are manually pulled up on the floor based on their location. The maps provide a bird’s eye view for the admin. For example, at any given time the admin can view the channels and see how much power the APs are transmitting, which makes it very easy to determine a situation with co-channel interference. Another feature allows the administrator to playback the station location with station tracking.



The configuration manager allows for a central location where an admin can make changes to any of the controllers in the network. This is particularly useful in the deployments in which multiple controllers are deployed. This also helps with remote upgrades that can be scheduled when multiple controllers are being managed.



The system categorizes reports based on stations, alarms, APs, network quality, etc. Each of these categories have different criteria that can be selected. For example, while pulling up a station report for a particular time period, the operator has the option to pull up a report based on the station usage, top talkers, etc. Reports can be customized and configured to be automatically generated periodically.



Spectrum Analysis
The Samsung APs support a dedicated sensor chip apart from the dual band radios that are client facing. This chip allows for spectrum scanning without affecting the performance of the dual band radios. Spectrum view offers the users real time FFT, duty cycle, and spectrogram and can be run selectively on either the 2.4 or the 5 GHz band. So, for example, an enterprise may have many locations, and assuming one of the locations is reporting issues with Wi-Fi (read: dropped sessions), an administrator can run a spectrum scan from one of the APs in that location (without bringing it out of commission) to get a sense of the RF environment. This way, there is no need for an onsite individual or a “truck roll” carrying expensive spectrum analyzers walking the sight.

WEM offers a full suite of Voice Quality Monitoring tools. This includes call quality reports with detailed MOS scores which help administrators understand if an issue related to voice quality is on the network side or the RF side. Real-time monitoring of calls allows the administrator to assess delays, loss-rate, etc.

Remote Packet Captures
This feature allows the administrator to initiate a packet capture for a particular station or AP. The traffic is captured after the packet has been decrypted off the CAPWAP session. So, all it would then need is a PC equipped with Wireshark running on the same network as the controller. Wireshark allows for a remote PCAP feature which talks to an interface on the controller that mirrors packets back to the PC. This is particularly helpful if administrators need packet captures straight from the station.
