What You Need to Begin

The SonicWALL SonicPoint-Ne/Ni security appliances are centrally managed by SonicWALL NSA E-Class appliances. For more

information on deploying this SonicPoint with SonicWALL NSA series and TZ series platforms, contact your local SonicWALL sales

representative for the supported SonicOS releases. SonicPoints receive auto-firmware updates from the central gateway SonicWALL,

this device supports SonicOS 5.6.0.3 or higher releases.

In addition to the above SonicOS firmware and hardware requirements, ensure that your network deployment includes:

• An 802.3af compliant PoE injector or PoE-capable switch (optional when using the SonicPoint-Ne)

• An active Internet connection

• A configured interface on the SonicWALL security appliance set to a zone type of “wireless”

• A location selected for placement of your SonicPoint such as a wall or ceiling

• Clients capable of 802.11n wireless communications1

1. Although clients with 802.11a/b/g hardware are supported, the presence of these legacy clients within range of your network may affect the connection

speed of your 802.11n clients.

Introduction to Secure Wireless

In this Section:

This section contains excerpts from the SonicWALL Secure Wireless Network Integrated Solutions Guide.

The content is meant to provide a brief introduction to Radio Frequency (RF) technology as it

pertains to different deployment scenarios.

Page 8 Wireless RF Introduction

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.

The following section provides a brief overview of RF

technologies:

•Frequency Bands and Channels - page 8

•802.11 Comparison Chart - page 8

•Radio Frequency Barriers - page 9

•RF Interference - page 9

Frequency Bands and Channels

To allow multiple separate wireless networks in a shared and

confined space, the RF medium is divided into channels. For

devices in the 5GHz range (802.11a), this means the possibility

of up to 23 discrete channels. For devices using the 2.4GHz

range (802.11b, 802.11g), the wireless space is limited to a

maximum of 14 overlapping channels. As a result of these

overlapping channels, 2.4GHz technology provides only a total

of three discrete channels.

The newer 802.11n technology does not fit into either of these

categories, as it is capable of using both 2.4GHz and 5GHz, but

is limited to 14 overlapping channels for backward compatibility.

802.11 Comparison Chart

The following table compares signal characteristics as they

apply to the current 802.11 standards:

802.11a 802.11b 802.11g 802.11n

# of Channels in USA 23 11 11 11

# of Channels in EU 23 13 13 13

# of Channels in Japan 15 14 14 14

Frequency Band 5GHz 2.4GHz 2.4GHz 2.4/5GHz

Max. Data Rate 54Mbps 11Mbps 54Mbps 150Mbps

300Mbpsa

a. Full 300Mbps throughput is possible only in environments free from

2.4Ghz interference.

Note: Although 802.11b/g/n standards provide between 11

and 14 channels, only 3 of those channels are fully

discrete (non-overlapping) channels.

Radio Frequency Barriers

Determining the location of RF barriers can be a painful part of

the placement process, but keep in mind that they can be used

beneficially in an attempt to block signals where you do not

want coverage.

The following tables list some common RF barrier types:

RF Interference

RF interference from home, office, and medical equipment is a

common source of frustration in wireless deployments from the

smallest home office to the largest multi-building campus.

The following table lists several common sources of RF

interference:

Barrier Type RF Signal

Blocking

Open air Very Low

Glass, drywall, cube partitions Low

Stone floors and walls (brick/marble/granite) Medium

Concrete, security glass, stacked books/paper High

Metal, metal mesh (chicken wire), re-enforced
