Omni-direction
al antenna
QuSpot
Link
External antenna with antennas in 4
directions. Utilized in urban environments
with lots of different tower locations nearby
Uni-directional
antenna
QuMax
Link
External antenna with single direction of
antenna. Strongest gain in one direction,
ideal for suburban and remote locations
Passive POE

UI
Passive
POE 24V
DC
Link
Used to power the RUT240 router, through
the LAN port. Warning: RUT240 does not
support standard POE, which would burn the
router. Only use this passive POE that’s 24V
DC output.
Network
Swiftlane uses AT&T as the primary provider for cellular connectivity. Please check the
general signal strength at the customer site, you can request this information ahead of
time from the customer or during your initial site assessment.

Wiring diagrams
Option 1: Using an external antenna, for cellular only internet
If Swiftlane provided internet is being used as the primary internet service, please follow
these wiring options. An external antenna is strongly recommended in this scenario to
maximize signal strength, especially since the signal can be weaker in server and IDF rooms
Option 2: Using external antenna and cellular as a backup to primary
wired internet

Option 3: Using the cellular router without an external antenna
If the signal strength inside the server room is strong, an external antenna may not be
required, and you can use the antennas that come bundled with the RUT240 router

Mounting Considerations for External Antenna
External antennas should be mounted outside the building with minimal obstruction from
nearby buildings. Identify the location that balances ease of installation with the maximum
unobstructed views, in order to achieve best gain from the antenna
●Balance ease of installation with aesthetic considerations for the building, and
minimal obstructions from nearby building
●For uni-directional antenna, the mount provides a 45 degree rotation angle, in order
to adjust the antenna horizontally and align with the nearby tower
●Use cellmapper.net to identify nearby towers to ensure maximum gain on the
antenna
Height
In general, the taller the antenna is placed, the better it will perform. However, 10-12 ft is a
good installation height to start. This protects it from easy access to vandalism, while also
getting few obstructions to the nearby towers. You can connect the antenna and hold it up
at that height and check the signal strength indicators by connecting to the local
management dashboard over an IP connection. Follow the instructions below to get
familiar with the various parameters for signal strength.
Direction
Omni - directional antennas capture signal strength from all directions so they dont to be
pointing in any specific direction
Uni-directional antennas must be pointed in the general direction of the nearest cell towers
for AT&T. You can use https://www.cellmapper.net/ to insert the full address and look up
nearby 4G towers.

Checking Signal Strength and Connectivity
Please use an Ethernet to USB converter so that you can
connect to the cellular router locally on a computer.
Remove the ethernet cable connected to the non-red side of the white POE injector, and
plug that into your computer.

Please contact [email protected] to request the password
Connect to the IP address 192.168.1.1 in the browser.
Go to network - mobile tab
Look under the section called “Network Frequency Bands” -> Connection Method

Set the “connection method” to automatic

This will restart the router. After a few min, you can log back in again and check this page
Go to Status -> Network
It wi
It will show you the signal strength and the “connected Band” in there.

You can see the meaning of various signal strength indicators here

TE)
The main indicators are
●RSSI - Received Signal Strength Indicator. RSSI is a negative value, and the closer to 0,
the stronger the signal
●RSRP - the Reference Signal Received Power is the power of the LTE Reference
Signals spread over the full bandwidth and narrowband
●RSRQ - Reference Signal Received Quality is a C/I type of measurement and it
indicates the quality of the received reference signal (similar to EC/IO)
●SINR - Signal to Interference plus Noise Ratio (A minimum of -20 dB SINR is needed
to detect RSRP/RSRQ). Indicates the throughput capacity of the channel. As the name
implies, SINR is the strength of the signal divided by the strength of any interference
There are many different factors that influence signal strength and quality, including but
not limited to:
●Tower load

●Proximity to the cellular tower
●Signal going through a cellular repeater
●Competing signals
●Physical barriers (mountains, buildings, trains, etc.)
●Weather
Setting up cellular failover to the WAN (wired internet)
In order to ensure that the router is able to fallback to the cellular/mobile signal whenever
the internet is down, make sure Failover is enabled in the router setting.
Go to Network -> Failover and then Toggle ON both both WAN and Mobile
The order of the records in this table matters as well. Please make sure to have WAN at the
top, and Mobile at the second row. This means WAN would be primary and Mobile is a
failover.
Antenna Location
Currently, the antenna is connecting to the tower to the south of the condo building. You
can see the cell tower location with respect to the fargo condos. Our goal should be to tilt,
the tower further south, and “refresh connection” from the System-> Network tab, and see

if the SINR, RSRP and RSRQ improve. Ideally, we can move the antenna to a south facing
location, to further improve these metrics. If the SINR goes above 20 Dbm this will result in
an excellent reliable signal long term. But it would be better even better at 15 or higher.

Location of towers
Look up the address in cellmapper - 1442 West Fargo Avenue, Chicago, IL, USA
https://www.cellmapper.net/
Search for the address in there, using the Search option on the left side.
Make sure to filter the provider as AT&T Mobility and Network as 4G

Debugging
Changing the static IP of the RUT240
Sometimes, the main internet router and the RUT240 might have the same default IP
address of 192.168.1.1 and this can cause the wired connection to keep failing. The installer
can update the static IP of the RUT240 using these steps
The default IP address of the RUT240 is 192.168.1.1 . It that conflicts with the main wired
router, you can manually change it under Network-> LAN

Checking what devices are connected to the router
Go to Network -> LAN. It will show the list of devices and their IP address
