WIRELESS LAN

ZyXEL is introducing the new NWA-3166 business hybrid access point including

802.11a/b/g/n. As a wireless controller, it o ers centralised management of up to 24

managed client access points (AP). Since it supports the standard IEEE 802.11n (Draft

2.0), zones with low radio coverage can be accessed more easily.

Up to 100Mbps Throughput

Up to now, such throughput rates could only

be achieved using Ethernet connections. The

MIMO technology employs several antennas for

transfer and thanks to re ections reaches a higher

throughput. This allows improved wireless LAN

coverage and thereby minimises so-called “dead

spots”.

WLAN a/b/g/n (Draft 2.0)

The ZyXEL NWA-3166 is certi ed according to the

latest WLAN standard IEEE 802.11n (Draft 2.0). In

addition, it can be operated in 11a mode. That

is why the access point ensures a high level of

investment protection. The range of possibilities

is endless and reaches from VoIP telephony and

hot spots to industrial process automation.

802.11a, b, g or n?

The ZyXEL NWA-3166 hybrid access point

operates in the 2.4 or 5GHz frequency range. This

of course poses the question of which technology

is optimal. With a single AP, ZyXEL not only

o ers 802.11n but also 11a/b/g in the one unit.

The right choice depends on the con guration.

If the con guration based on closely installed

access points is complex, then implementing

an 11a or g is recommended. Con guring the

cells on 802.11n can be more complex since up

to two neighbouring tunnels need to be used.

In this connection, 802.11n is more suitable for

high data transfer rates, especially in the 5GHz

range. While the ZyXEL NWA-3166 is equipped

with embedded omni-directional antennas,

external antennas can be attached to the ZyXEL

NWA-3100, 3160 and 35x0 models.

Hybrid Access Point

The ZyXEL NWA-3166 can be implemented in

stand-alone AP architecture or as a controller-

Hybrid Access Point for 802.11a/b/g/n

managed solution for other NWA series units.

Up to 24 managed access points are supported

(ZyXEL NWA-3160, NWA-35x0 and NWA-3166).

As a result, this model provides a scalable

and inexpensive alternative to traditional and

expensive controller systems. Besides controller

management, the ZyXEL NWA-3166 can also

be implemented as a stand-alone AP. Client APs

allow full  exibility in con guration according

to relevant functions from the controller.

Communication with the client APs is e ected via

secure tunnels using CAPWAP protocols.

Advanced Features

Thanks to wireless PoE (Power over Ethernet)

support, power from conspicuous wall plugs

is no longer required. In addition, Quality of

Service along with a pre-de ned VoIP pro le

are available together with guest access and

the option of Layer 2 isolation. Up to 16 virtual

wireless networks (multi SSID) combined with

VLAN tagging (802.11Q) enable the simultaneous

connectivity of several user groups using only

one access point. Furthermore, the ZyXEL

NWA-3166 also features an internal or external

RADIUS authentication function.
