Wireless RF Introduction
There are currently four widely adopted standards for 802.11
wireless network types: a, b, g, and n. Although 802.11n is the
newest and highest capacity standard, each of the four
standards has its own strengths and weaknesses. This section
provides overviews of these standards.

Access Points and Network Design
Physical placement of an access point has a measurable effect
on who can and cannot access your wireless signal. The
following sections provide an overview of wireless access point
placement, signal strength, and signal direction in common
wireless deployment situations:
Hardware Decisions - page 9
Solutions to RF Interference and Barriers - page 10
Tip: For the latest SonicPoint wireless deployment
information from switching recommendations to
site survey, see the SonicWALL SonicPoint
Deployment Best Practices Guide at:
<http://www.sonicwall.com/us/support.html>
Hardware Decisions
The first decision in hardware is the access point. While access
point technology (802.11a/b/g/n) is one factor in determining
your placement, based on distance served and bandwidth
needed, taking note of other hardware-based factors is just as
important.
Some hardware factors to take into consideration:
Number of access points versus user density – If too
many users are serviced by a single access point,
maximum transfer rates are reached and that point may
become a bottleneck for the whole system.
Bandwidth – How much data is moving upstream and
downstream for a given type of user?
Ethernet cabling – Where are you running the powered
Ethernet (PoE) cable to and how are you securing that
cable? Is your PoE switch able to power all access points?
Hubs / Switches / Security Appliance – Your wireless
deployment has to tie back into your SonicWALL security
appliance and LAN resources at some point. What speed is
needed for your Ethernet connection to accommodate the
number of access points you are installing? Also consider
where your key networking devices are deployed and how
they will connect efficiently with your wireless appliances.
Ethernet connections for 802.11n – In most cases,
802.11n wireless hardware requires more bandwidth than a
single (or even dual) 10/100 Ethernet connection can
handle. Gigabit Ethernet connectivity between the WLAN
and the LAN is required to take full advantage of 802.11n
speed.
Power Over Ethernet (PoE) – Part of your wireless
network planning should include verifying that your PoE
equipment is 802.3at compliant, and that full power can be
supplied to each SonicPoint.

Solutions to RF Interference and Barriers
These days, finding an environment with no RF interference or
noise is nearly impossible. Only if you are setting up an office in
a secluded redwood grove can you count on RF interference to
be a non-issue. Even then, the redwood trees might just be
among those fitted with high-gain cellular antennas, an all-too-
common occurrence today. Regardless, you should expect to
deal with some level of signal interference in your deployment.
Location A – Rogue access points or wireless test lab
Problem – Wireless product test labs and other (non-
malicious) rogue access points are problems in many Wi-Fi
deployments.
Solution Either eliminate all rogue access points, or
force their owners to use a set channel that does not
overlap with your distributed wireless solution.
Location B – Spectrum noise for 2.4 GHz and 5 GHz
Problem Your phone system is partially wireless and
uses the 2.4GHz or 5GHz spectrum.
Solution Give VoIP a try. VoIP will work in tandem with
your wireless network, instead of against it. For more on
SonicWALL VoIP implementation and capabilities, refer to
the Configuring VoIP SonicOS feature module available at:
http://www.sonicwall.com/us/support.html
Location C – Off-network access points
Problem Your neighbors need wireless, too!
Unfortunately, only a few sheets of drywall separate you.
Solution Overpowering your neighbors with high-gain
antennas is an option, but not a particularly neighborly one.
Instead, you could simply use a different channel for
wireless access points bordering this wall and ensure that
your neighbors do the same. Performance in some dual-
channel wireless devices may take a hit, but it is better
than dropped connections—or unhappy neighbors.

Page 18 Installing Antennas
Installing Antennas
To install the SonicPoint-N Dual Radio included antennas:
1. Remove the six (6) antennas from the bag and place each
on the appropriate connector, keeping in mind that two
antenna/connector types exist.
2. Carefully finger-tighten the fittings.
Note: The proper antennas will fit easily into the appropriate
connection. Never force an antenna onto a connector.
3. Adjust the antennas for reception, keeping in mind that
orienting the antennas vertically provides optimal wireless
coverage in most cases.
The circular design of the SonicPoint aides in creating a strong
multi-directional wireless signal pattern for both radio bands. In
most cases, leaving the antennas straight up (as indicated in
the illustration) will provide the best overall coverage.
Note: The antennas provided by SonicWALL are designed to
provide optimal signal strength and coverage within the
confines of regulatory laws. Only use the antennas
provided by SonicWALL with this appliance.
Connecting Ethernet Cable
To connect the SonicPoint to your network:
1. Using CAT5, CAT5e, or CAT6 cabling, connect the “lan”
port of the SonicPoint to the interface you previously
configured on the SonicWALL security appliance.
2. Optionally, SonicPoints may be powered by using the
SonicWALL 802.11at PoE line injector (sold separately), or
by using a third-party 802.3at compliant PoE switch.
Note: If using a PoE switch/injector to power the SonicPoint,
ensure that the switch/injector is 802.11at compliant
and rated to deliver at least 25.5 watts. Always read
and comply with instructions and warnings provided
with the PoE before connecting the device to your
SonicPoint.

Page 22 Troubleshooting Tips
Troubleshooting Tips
If the SonicPoint locates a peer SonicOS device, the two units
perform an encrypted exchange and the profile assigned to the
relevant wireless zone is used to automatically configure
(provision) the newly added SonicPoint unit.
Your SonicPoint is automatically included in the list on the
Wireless > SonicPoints page of the management interface for
the SonicWALL security appliance managing the SonicPoint. If
it does not show in the list:
Make sure the SonicPoint is connected to an interface
that is configured as part of a Wireless zone. Either the
default WLAN zone, or a custom zone with type set to
“wireless” is required.
Click the Synchronize SonicPoints button. This is
located in the SonicOS management interface on the
SonicPoint > SonicPoints page and forces the SonicWALL
appliance, if connected, to download a new SonicPoint
image from the SonicWALL back-end server.
Ensure that the SonicPoint is connected to a 802.3at
compliant PoE if using PoE to power your SonicPoint
appliance.
Verify that your PoE switch/injector is rated to deliver
at least 25.5 watts of power to each port. Some older PoE
devices do not provide sufficient power to properly run
current generation dual radio 802.11n devices across
multiple ports. Check with your PoE manufacturer for
802.3at support, or use a SonicWALL 802.3at PoE injector.
Onboard Help System
All SonicWALL network security appliances include an onboard
help system with help topics that are relevant to each area of
the management interface. To access SonicPoint help, click the
Help icon in the upper right-hand corner of the SonicOS
management interface while you are on a SonicPoint page.

Page 24 Using the Wireless RF Score
Using the Wireless RF Score
The RF Score is a calculated number on a scale of 1-10 which
is used to represent the overall condition for a channel. A high
channel RF score (depicted in green) indicates a better quality
RF environment.
SonicWALL wireless drivers report signal strength in RSSI, this
number is used in the below equation to get a raw score on a
scale of 1 to 100.
Preliminary RF Score Formula:
rfaScore100 = 100-((rssiTotal-50)*7/10))
simplified: rfaScore100 = -0.7*rssiTotal + 135
The Final (1-10) RF Analysis Score:
If the RFA score is greater than 96, it is reported as 10.
If the RFA score is less than 15, it is reported as 1.
All other scores are divided by 10 to fall into the 1-10 scale.
Note: This feature depends on the knowledge of what
channel a SonicPoint is operating in. If the channel
number is unknown, RF Score is not shown.
Channel Utilization
The channel utilization graph shows how channels are being
utilized for each SonicPoint.
The number on the top of each color bar indicates the average
signal strength magnitude each SonicPoint detects for the
indicated channel. High magnitudes (greater than 240) are
shown in red and generally indicate that the corresponding
channel is overloaded.
Note: Although some channels are not used in all countries,
they are still shown, as it is possible for a wireless
cracker to launch denial of service attacks to adjacent
channels.

Viewing Overloaded Channels
RF Analysis shows devices operating in each channel. A
warning is displayed when it detects more than four active APs
in the same channel, regardless of how strong the signal
strength is.
Information about each discovered access point includes: SSID,
MAC, signal strength, and channel. Two values are shown for
signal strength: dBm and percentage value, where higher
numbers indicate stronger signals.
RFA Highly Interfered Channels
Access points working in adjacent channels (less than 5
channels apart) can also interfere with each other.
The RF Analysis feature displays a warning when a SonicPoint
appliance detects more than five active access points nearby
operating in adjacent channels.
Again, regardless of the signal strength from interfering access
points, RF Analysis marks the channel as highly interfered.

NOTE: This equipment was tested and found to comply with the limits for a Class B
digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference in a residential
installation. This equipment generates, uses, and can radiate radio frequency
energy. And, if not installed and used in accordance with the instructions, may
cause harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation. If the
equipment does cause harmful interference to radio or television reception, which
can be determined by turning the equipment off and on, the user is encouraged to
try and correct the interference using one or more of the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and the receiver.
Connect the equipment into an outlet on a circuit different from the receiver
connection.
Consult SonicWALL for assistance.
Caution: Any changes or modifications not expressly approved by the party
responsible for compliance could void the user's authority to operate this

with any other antenna or transmitter.
United States of America Authorized Channels
SonicWALL declares that the APL23-081 (FCC ID: QWU-081) when sold in US is
limited to CH1~CH11 by specified firmware controlled in the USA.
Operation is subject to the following two conditions:
(1) This device may not cause harmful interference, and (2) this device must
accept any interference received, including interference that may cause undesired
operation.
Caution:
This device is for indoor usage to reduce potential for harmful interference to co-
channel systems.
The APL23-081 device has been designed to operate with an antenna having a
maximum gain of 4dBi at 5GHz and 3dBi at 2.4Ghz. Antenna having a higher gain
is strictly prohibited. The required antenna impedance is 50 ohms.
Dynamic Frequency Selection(DFS) is required on all Wireless LAN Mater devices
(usually Access Points) and Wireless LAN Clients (usually Wireless NICs) that
operate within 5470 MHz – 5725 MHz. SonicPoints that have these frequencies
and channels enable in this range comply with North American and International
DFS requirements. Some frequencies are blocked, and cannot be selected by the
user per each specific regional approval.
Specific to the USA; at the urging of the Federal Communication Commission
(FCC) user/installers should avoid operation frequencies near Terminal Doppler
Weather Radar (TDWR) systems frequencies 5600-5650 MHz when installing
SonicPoint within 35 km of line-of-site of TDWR sites. If TDWR is within 35 km the
SonicPoint frequencies should be set to at least 30 MHz above or below any
TDWR system frequency at that site. TDWR locations and specific frequencies
used can be found at <http://spectrumbridge.com/udrs/home.aspx>.
