Learn how to use the realtime view in Hamina Onsite.

The real-time view uses the Oscium Nomad to perform real-time Wi-Fi scanning. It displays information about nearby access points, such as their signal strength and operating channel. While the Realtime view is active, the Oscium Nomad or WLAN Pi continuously sweeps across all 2.4, 5, and 6 GHz channels to refresh the data.
Scroll down to view the Realtime view, Spectrum, and the Networks and APs tables.
The Realtime and Spectrum views use a network selection to differentiate between your access points, and neighboring access points.
Use the 2.4 GHz, 5 GHz, and 6 GHz tabs at the top to switch between frequency bands. Then, select your network by tapping the Network Selection Menu in the upper right, where you can pick your network.
If the Hamina Onsite app has permission to access location services, then it will automatically select the network that your iPhone, iPad, or MacBook is associated to.
The Realtime Graph shows the signal strength for the current selected band and SSID. This view is great for doing spot-checks to make sure there is sufficient primary coverage and secondary coverage, and to ensure that there isn't a nearby access point on the same channel as your network.
Dark sparklines - Coverage from either the Primary AP, or Secondary AP. Of the two dark sparklines, the Primary AP is always on the top.
Primary AP - Primary Coverage, which is coverage from your network's loudest access point.
Secondary AP - Secondary Coverage, which is coverage from your network's secound-loudest access point.
Dim sparkline - Neighbor AP, which is the signal strength of the loudest neighboring access point.
The labels on the far right of the graph show each access point's channel. Note that these labels will change as you move around, and different access points take the place of Primary AP, Secondary AP, and Neighbor AP.
The Spectrum Graph is a combination graphical Wi-Fi scanner (using Wi-Fi scanning data from the Oscium Nomad or WLAN Pi) and spectrum analyzer (using a connected spectrum analyzer such as the Oscium WiPry Clarity or Wi-Spy Lucid).
Each "ziggurat" represents an access point radio. The height of each ziggurat represents the signal strength of the access point, and the width represents how wide of a channel the access point is using.
Solid lines - Access points belonging to the selected SSID
Dashed lines - Access points that belong to other SSIDs
In the Configuration popover, uncheck Show access points to hide it in the Spectrum Graph.
The Spectrum Density graph uses colors to indicate, over a 30-second timespan, how often a particular frequency and amplitude were utilized. The height of the graph indicates the amplitude (signal strength) of transmitters and noise in the spectrum, while the color indicates utilization over the 30-second rolling timespan.
Light green - 0-10%
Green - 10-30%
Orange - 30-50%
Red - 50-100%
In the Configuration popover, uncheck Show spectrum density to hide it in the Spectrum Graph.
If a compatible spectrum analyzer is connected, Hamina Onsite will generate a Spectrum Density graph (using color by utilization). Hamina Onsite supports the following spectrum analyzers:
Oscium WiPry Clarity
The spectrum analyzer connects to the Spectrum port (type USB-A) on the Oscium Nomad using the included USB-A to USB-C cable. There is a small pocket in the shoulder strap for the Oscium Nomad for the spectrum analyzer.
If no compatible spectrum analyzer is connected, Hamina Onsite will still generate a Spectrum Density graph (using color by utilization) using the QBSS Load IE from nearby access points. The result is an indicator of Channel Utilization from the perspective of the access points, instead of a spectrum analyzer.
In the Spectrum Graph, pinch-to-zoom on the graph to change the zoom level. Drag left and right to pan the graph, or drag the Viewport in the Minimap to pan the graph.
When a compatible spectrum analyzer is connected, Hamina Onsite will automatically tune the start frequency, stop frequency, and resolution of the Spectrum Density graph depending on the zoom level. When the graph is panned, the spectrum analyzer will re-tune to sweep the visible part of the graph.
In the minimap:
Dark grey - Spectrum that is currently being updated
Grey - A previous snapshot of spectrum that is not currently being updated
In the main spectrum graph:
Vibrant colors - Spectrum that is currently being updated
Desaturated colors - A previous snapshot of spectrum that is not currently being updated
Using the QBSS Load IE from the access points, this table displays how many clients are associated to each access point.
My row - How many clients are connected to access points that are broadcasting the selected SSID. Note: the client count is repeated for each 20 MHz channel, but they are not additive.
Other row - The total of clients on the channel that are connected to access points that are not part of the selected SSID.
Each cell of the table will change colors depending on how many clients are present on the channel. See the Configuration popover for a legend.
At the bottom of the Live View is the Networks table, and the APs table. You can switch between them using the Networks and APs tabs.
The Networks table shows a list of all of the nearby SSIDs in the selected band. The table shows:
SSID - Shows the name of the network.
Width - Shows the width of the network, in MHz. It is assumed that all APs on the network use the same width.
Sec. - Shows the security type advertised by the network.
Min. D - Shows the minimum basic data rate supported by the network.
Signal - Shows the primary signal strength (loudest AP) from the network.
The APs Table shows a list of all nearby BSSIDs in the selected band. The table shows:
MAC - The MAC address/BSSID of the access point radio.
SSID - The advertised SSID. --- denotes a hidden SSID.
Ch. - The channel that the radio is on.
Wi-Fi - The newest generation of Wi-Fi that is supported by the radio.
Signal - The signal strength of the radio
Vendor - An icon that shows which vendor the access point radio is from. If we can't tell the vendor from the OUI (first three nibbles of the MAC address), then a walrus is shown.
Hamina does not sell the Oscium Wi-Spy Lucid, but it can be purchased .
