Wireless overview

The Dell™ SonicPoint N2 is part of the next evolutionary generation in wireless access points after the Dell SonicWALL SonicPoint
N and NDR.

The SonicPoint N2 provides physica l layer enhancements for higher throughput with a maximum data rate of 450 Mbps. T o achieve
this, the SonicPoint N2 uses:

• More antennas—three antennas for the 5 GHz radio, and three more for the 2.4 GHz radio

• Wider channels—40 MHz-wide channels for the 802.11n radio module

• More spatial streams—3X3 multiple-input and multiple-output, (MIMO) for the 802.11n radio module, where the capacity

of a radio link is multiplied using multipath propagation.

When a wireless device uses a Dell SonicPoint N2 wireless
access point to communicate with a wireless device on
another subnet or on a completely dif ferent network, traffic
between the devices is forced to traverse the Dell SonicWALL
network security appliance. This traversal enables security
services to be enforced by SonicOS.

Standard practice for wireless firewalling (where one wireless
client is communicating with another) bypasses many of the
critical security services. The following illustration shows the
standard practice for wireless firewalling.

Figure 1. Standard wireless firewalling

Many security products on the market share this potential
vulnerability when two users connected by a common hub or
wireless access point wish to exchange data.

Dell SonicWALL addresses this security shortcoming by
managing the SonicPoint access points from the network
security appliance. This allows complete control of the
wireless space, including zone enforcement of security
services and complete firewalling capabilities.

Frequency bands and channels

There are currently five widely adopted standards for 802.11 wireless network types: a, b, g, n, and ac. 802.11n and 802.11ac are
the newest and highest capacity standards, but older client devices may not be able to utilize the newer standards.

Table 1. Wireless standards

802.11 (x) Frequency standard Maximum data rate

802.11a 5 GHz 54 Mbps

802.11b 2.4 GHz 11 Mbps

802.11g 2.4 GHz 54 Mbps

802.11n 2.4 GHz and 5 GHz 450 Mbps

802.11ac 5 GHz + multichannel + multipath 1.3 Gbps

Different frequency bands provide varying signal strength and quality over differe nt distance ranges. Signals in the 2.4 GHz range
tend to pass through physical barriers better and carry farther than those in the 5 GHz range, but they do not provide as high a
data rate. Signals in the 5 GHz range provide faster data rates for better throughput, but the signal attenuates faster and is best
suited for open spaces.

Table 2. Strengths and weaknesses of 5 GHz and 2.4 GHz signals

5 GHz 2.4 GHz

Strength Higher speed, more channels Longer Range, stronger signal penetration
Weakness Limited penetration of walls, client compatibility More sources of interference

Refer to Radio frequency barriers and RF interference on page 18 for detailed information about RF barriers and interference.

To allow multiple separate wireless networks in a shared and confined space, the RF med ium is divided into channels . For devices
in the 5 GHz range (802.11a/n/ac), this means the possibility of up to 23 discrete channels.

For devices using the 2.4 GHz range (802.11b/g/n), the wireless space is limited to a maximum of 14 overlapping channels. As a
result of these overlapping channels, 2.4 GHz technology provides only a total of three discrete channels.

SonicOS firmware

• Dell SonicPoint N2 a ccess points are centra lly managed

by Dell SonicW ALL network security appliances running
the following versions of SonicOS:

• SonicOS 5.9.1 or a higher 5.9 release

• SonicOS 6.2.2 or higher

Power over Ethernet

• An 802.3at compliant PoE injector or PoE-capable

switch capable of providing 25 watts of power to each
SonicPoint N2 is required.

Internet connectivity

• An active Internet connection is required for your

firewall to download the latest SonicPoint firmware.

Gigabit Ethernet connectivity

• 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.
