Wireless overview
The SonicPoint N2 is part of the next evolutionary generation in wireless access points after the SonicWall SonicPoint N and NDR.
The SonicPoint N2 provides physical layer enhancements for higher throughput with a maximum data rate of 450 Mbps. To 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.

SonicWall wireless firewalling
When a wireless device uses a SonicWall SonicPoint N2 wireless access point to communicate with a wireless device on another subnet or on a completely different network, traffic between the devices is forced to traverse the 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.

Security Services |
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.
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.

Different frequency bands provide varying signal strength and quality over different 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.

Refer to Radio frequency barriers and RF interference on page 16 for detailed information about RF barriers and interference.
To allow multiple separate wireless networks in a shared and confined space, the RF medium 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.

Any items missing?
If any of the items corresponding to your product are missing from the package, contact Technical Support at: https:// support.sonicwall.com/contact support
A listing of the most current support documents are available online at: https://support.SonicWall.com/SonicWall SonicPoint series/ ace/release notes guides
Deployment requirements
SonicOS firmware
•SonicWall SonicPoint N2 access points are centrally managed by SonicWall network security appliances running the following versions of SonicOS:
•SonicOS 5.9.1.6 or a higher 5.9 release
•SonicOS 6.2.5.1 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.
See Product safety and regulatory information on page 29.
