Chapter 1
Introducing the Extricom Wireless
LAN S stem
Wireless LAN (WLAN) enables mobile users to connect their laptops, PDAs, and wireless phones
to the enterprise network instantly and effortlessly anywhere in the enterprise. However, using
WLAN in a large enterprise has been hindered by the challenges of current WLAN technology,
such as poor coverage, low capacity, high latency mobility, and expensive site-survey and
maintenance costs.
Extricom’s WLAN introduces a completely new, patent-pending, Interference-FreeTM architecture
that eliminates the coverage and capacity limitations and tradeoffs of traditional WLAN
architecture. The need for cell planning and site surveys, a highly expensive aspect of owning a
WLAN, is also eliminated. In addition, Extricom’s novel approach does away with most of the
WLAN maintenance. Extricom’s WLAN is specifically designed to provide increased network
capacity, seamless mobility, high level of security, and easy installation and configuration.
Overview of the Extricom WLAN S stem
The Extricom WLAN consists of a wireless switch (EXSW-800) and Access Points (EXRP20). The
Extricom WLAN system architecture replaces the concept of a cell planning based Access Point
(AP) deployment topology with blankets of continuous coverage for the entire enterprise.
Blanket coverage provides full coverage of a WLAN deployment area with multiple channel
blankets. In this channel blankets based system, every AP throughout the deployment area uses the
same channels. This kind of solution is enabled by Extricom’s advanced technology.
Figure 1. Two Channel Blanket Coverage

4 Introducing the Extricom Wireless LAN System
The Extricom WLAN system is centrally controlled by the switch, where the system intelligence is
located. Controlling the system is straightforward and easy to install and configure. The minimal
configuration required is performed via a dedicated, secured Web interface.
Features and Benefits
Extricom’s WLAN system solution offers the following features (* = Future capabilities):


Ease of deployment - No cell planning, no RF site surveys
Extricom’s patent-pending Interference-Free™ architecture requires no cell planning, and
allows ubiquitous placement of APs wherever convenient. There is no need for RF site surveys
or maintenance, eliminating a significant cost of deploying and owning a WLAN.


Uplink Access Point diversity
Extricom’s patent-pending uplink AP diversity selects the best AP to process a client’s packets
on a per packet basis. APs may be added at will, providing complete coverage, while avoiding
co-channel interference.


Multiple channels
Extricom’s Interference-Free architecture provides multiple channels everywhere in the
enterprise. The result is multiplied, aggregate capacity in separate channels that can also support
separating voice from data traffic. Furthermore, Extricom’s solution supports multiple channels
in the same frequency band at each AP (for example, channel 1, 6 in 2.4 GHz frequency band).


Zero-latency roaming
In an Extricom WLAN, the client remains on the same channel everywhere in the enterprise.
Inter-AP handoffs occur without any delays or packet loss, permitting a highly secure WLAN
(using advanced encryption and authentication methods), without affecting user mobility.


WiFi collaboration
Extricom’s patented WiFi Collaboration TM technology overcomes the difficulties of using RF
for data networks. By placing multiple APs on the same channel and making intelligent
decisions at the Wireless Switch, an Extricom WLAN avoids interferences, is very tolerant to
RF instabilities, and transparently provides network redundancy.


Dense Access Point deployment
In an Extricom WLAN, APs can be deployed densely without increasing the interference. This
allows users to always be close to an AP. The result is high data rates and reduced power
consumption for hand held-devices. Furthermore, Extricom’s system allows you to define a
transmitted data rate that is guaranteed to be the minimal data rate transmitted by the APs
throughout the coverage area of the enterprise. Extricom’s ability to provide a dense AP
deployment allows these minimal data rates to be defined with high values while still providing
excellent coverage.


Wire-line quality VoWLAN
Extricom’s Interference-Free architecture is perfectly suited for VoWLAN providing
zero-latency mobility, voice and data separation, reduced power consumption, and high RF
resiliency, all together resulting in superior voice performance. In addition, voice packets are
transmitted with SIFS and short preamble. Voice packets are broadcast in the downlink and are
bundled for a user-defined amount of time.

The Extricom EXSW-800 WLAN Switch User Guide 5


IEEE 802.11i support
Extricom’s products support WEP-64, WEP-128, WPA-TKIP encryption. The authentication
modes supported are: RADIUS (802.1x) and WPA Pre-Shared Key (PSK).


Power save
Full power conservation management is enabled for associated mobile devices over unicast,
multicast, and broadcast frames. For multicast and broadcast frames, the DTIM (Delivery
Traffic Indicator Message) can be determined via a Web interface.


2-Channel support within a single band
2 channels within a single band are supported for all bands, as defined in 802.11a, b, and g. This
enables the Extricom system to transmit on 2 different channels within the same band.


Centralized configuration
New switches can be added to the network via a single Web interface either manually by the
user, or automatically using an Extricom protocol.


System redundancy
Extricom enables full redundancy by connecting two switches in parallel to different APs over
the same area. The switchover parameters are user-configurable, and the Active to Standby
switchover is seamless to the user.


Enhanced SNMP traps
The Extricom system supports SNMP traps, enabling the user to determine the status of the
system, including the status of Access Points and Redundancy statuses.
Summar
The Extricom WLAN is perfectly suited for any enterprise WLAN deployment. It eliminates the
cost and complexity of cell planning and site surveys. The enterprise is completely covered with a
high-capacity, wireless network that seamlessly scales up as new areas of coverage are needed.
Additionally, the Extricom WLAN system provides seamless mobility, a high level of security, and
easy installation and configuration.

6 Introducing the Extricom Wireless LAN System
Overview of the Extricom Switches
The Extricom EXSW-800 switches provide central control and configuration of the WLAN. The
switches implement the Interference-Free architecture in the Extricom WLAN. With the
EXSW-800 switch you can connect up to 8 Access Points, providing two blankets of continuous
coverage for the entire enterprise.
Figure 2. Extricom EXSW-800 Switch
The switch avoids co-channel interference, overcoming the limitations of traditional WLAN
systems. Wi-Fi Collaboration technology enables the switch to dynamically adapt to the changing
RF environment and control the APs on a packet-by-packet basis. The need for WiFi cell planning
and RF site surveys is eliminated.
Configuring the entire enterprise deployment can be as simple as configuring a single AP, greatly
reducing the effort required to deploy and maintain the WLAN.
The minimal configuration required for the switch is performed via a dedicated secured Web
interface.

The Extricom EXSW-800 WLAN Switch User Guide 7
Overview of the Extricom Access Points
Extricom’s Access Points (EXRP20) enable Extricom’s Interference-Free architecture. This
architecture provides complete enterprise WLAN coverage, while eliminating co-channel
interference. APs can be placed as close together as necessary to provide high-quality, high-speed
connectivity from all locations within the enterprise.
Figure 3. Extricom Access Point
Each Access Point contains two standard 802.11a/b/g radios supporting two simultaneous channels.
Specifically, Extricom’s APs can also support two different channels (frequencies) in the same band
(for example, channel 1, 6 in the 2.4 GHz band), or alternatively, two frequencies from different
frequency bands). These plug and play APs contain no software, and therefore require no specific
user configuration or maintenance. If stolen, they do not pose a security risk. Since the APs are
powered by the standard 802.3af Power over Ethernet (PoE), only a single CAT-5 cable connection
is required to support two simultaneous radios.

Extricom APs only function in when they are directly connected to Extricom
switches.

8 Introducing the Extricom Wireless LAN System
A T pical Extricom Wireless Network Topolog
Extricom’s switch is connected to the wired LAN, and the APs spread throughout the enterprise.
Figure 4 displays a typical Extricom enterprise topology, consisting of an Extricom switch and
eight APs.
Figure 4. Typical Extricom Typology
Extricom uses standard WLAN protocols (IEEE 802.11). As a result, any 802.11a/b/g standard
client can work seamlessly with the Extricom system.
Extricom uses standard Ethernet connections to the wired LAN network. APs are connected to the
Extricom switch using standard CAT-5 Ethernet cabling and are powered by the standard compliant
IEE 802.3af Power over Ethernet (PoE).

10 Installing the Extricom WLAN System
Determining the Location of the Extricom Access
Points
Before installing the switch and Access Points, plan the placement of the APs. Before permanently
mounting the APs, it is recommended to test the network (using a laptop client) to identify potential
problems such as coverage holes. If such a problem exists, Extricom’s advanced technology enables
you to easily add or relocate the APs without any need for frequency or cell planning.
The APs should be placed in a stable, secure location, such as on top of a closet or bookshelf, or
mounted on a wall.
The switch should be placed near the distribution point of the LAN line. This is usually in the
communication cabinet of your enterprise.
