Caution
Cautions against unpacking and assembling the product components
- Do not give excessive shock on the product.
- Check each connector and screw very carefully when reassembling after the
components are unpacked once. The reassembled product shall not have any
spaces between the housing and the base.
Cautions against mounting the 8WLI card
The 8WL card can be installed in the OfficeServ 500 System. Do not use this card on
other systems.
Cautions against installing the desk WBS24
When putting the WBS24 on the desk, do not install the WBS24 at an unstable
location or on a smaller prop than the WBS24 system.
Caution when setting the WBS24 SECOND IP
To use the Internet network, the first three digits of the IP assigned to the WBS24 and
the first three digits of the SECOND WBS IP of the WBS24 must be identical. If the IP
assigned to the WBS24 and the Station is 168.219.149.xxx, then the SECOND WBS
IP of the WBS24 shall be 168.xxx.xxx.xxx.
Cautions against the roaming of the WBS24
If the PC is roamed to another WBS24 while upgrading, the upgrade will be
interrupted and the flash memory will not be functioning. Accordingly, locate the PC
as close as possible from the WBS24. To prevent roaming to another WBS24, it is
recommended that all of the WBS24 power should be turned off for safety.
Prevention of executing the ‘flo’ command
If the ‘flo’ command is executed, the power of all base stations connected to the 8WLI
card is turned off and their wireless LAN function will be interrupted.
CAUTION

Cautions against handling the board
When connecting a line cord after a board is dismantled, do not place a board near
metal and conductive objects.
Prevention of Electrostatic Hazards
When handling an electric component, wear an anti-static wrist strap or discharge the
electrostatics from your body by touching a grounded object periodically.

Overview
This chapter describes the general introduction of wireless LAN, functions of
OfficeServ 500 wireless LAN, components of OfficeServ 500 wireless LAN, and
specifications for WBS24, 8WLI Card and WIP-5000M mobile phone.
1 Overview of Wireless LAN
The LAN can be distinguished into two different kinds, wired LAN and wireless
LAN, depending on the mobility and presence of stations.
The wireless LAN converts data between personal computers or between servers into
radio waves or optic signals, and transfers/receives them wirelessly. When installing a
network, either radio frequency(RF) or light is used to install a network from hub to
client.
Advantages of Wireless LAN
The advantage of using LAN are described as follows :
 Installation and maintenance are simple that the relevant personnel and
equipment can be easily replaced. There is no need to do additional power line
work.
 It is easy to install a network in an emergency situation
 It supports full user mobility in such applications as mobile station and portable
terminal.
 It solves cabling problems on the open sites where wiring is difficult, such as
exhibition, seminar, registrar, temporary building, and construction site.
 It solves the problems of network stoppage during natural disasters.
 It provides user mobility for mobile station and portable terminals in such areas
as the department stores, museums and factories.

CHAPTER 1.Overview OfficeServ 500 Wireless LAN Service Manual/Ed.00
Page 1-2 © SAMSUNG Electronics Co., Ltd.
2 Overview of OfficeServ 500 Wireless LAN
The OfficeServ 500 system, which is the key telephone system of Samsung, offers
voice or data service in a wireless LAN and can simultaneously send/receive voice
and data.
The wireless LAN service is offered through WLAN Base Station 2.4 GHz(WBS24),
which is an Access Point(AP) device. The WBS24 is classified into two types as
follows :
Wireless LAN Service Through the WBS24 (Combo)
The WBS24(Combo) interfaces with the OfficeServ 500 system through LAN and
offers the voice/data service.
 WBS24(Combo) : Offers the voice service through the 8WLI card that functions
as the wireless LAN. One 8WLI card supports up to eight WBS24(Combo)s.
 The WIP-5000M is used as a terminal for the voice service.
 Laptops on which a wireless LAN card is mounted or PDAs are used for the data
service.
Wireless LAN Service Through the WBS24(Basic)
The WBS24(Basic) interfaces with the IP network through LAN and offers the
voice/data service.
 WBS24(Basic) : MGI1/2/3 or ITM3, which functions as a VOIP gateway, offers
the voice data.
 The WIP-5000M is used as a terminal for the voice service.
 Laptops on which a wireless LAN card is mounted or PDAs are used for the data
service.
Major Functions
The wireless LAN of OfficeServ 500 System has the following features :
 Wireless Standard : IEEE 802.11b
 Data rate : 11 Mbps(Max), 5.5 Mbps, 2 Mbps, 1 Mbps
 Modulation : CCK, BPSK, QPSK
 Network architecture : Ad-hoc, Infrastructure
 Security Function : WEB 64/128-bit encryption
 Output Power : Max. 100mW(NIC Card 70mW)
 Channels : 13 channels(Korea)/11 channels(USA)
 Interface : PCMCIA
 Frequency : 2400~2483.5 MHz
 Antenna Gain : 2.0 dBi
 Beam-Width : Omni directional(Dipole)
 Diversity Support

OfficeServ 500 Wireless LAN Service Manual/Ed.00 CHAPTER 3. Installation
© SAMSUNG Electronics Co., Ltd. Page 1-3
 The voice service is provided even in no-wired LAN environment.
 The quality of service(QoS) is guaranteed using the exclusive voice path.
 Since the OfficeServ 500 System supplies power remotely to the WBS24, no
separate electric wiring work is needed.
 The transmission distance between the OfficeServ 500 System and the WBS24
is 600 meters, so the cell can be easily designed.
 Since the built-in phone function is supported, a phone number can be assigned
instead of an IP address when registering a user.
 The call path generation/maintenance and handover functions are provided.
 The echo cancellation and voice codec(G.729, G.723.1) functions are provided.
 The system supports the back-up battery, so the phone conversation can be
maintained during an electric failure.
 Even if the ISM band is used, the VoIP is supported. So, there are almost no
interferences.
 Easy upgrade
 AP O & M function
Extension of the transmission distance
In case of the wired LAN, the transmission distance is only 100 meters in maximum.
To extend the distance, either hub or repeater is needed.

3.1 OfficeServ 500 System
3.1.1 Overview
The OfficeServ 500 System is the primary device of phone that provides the wireless
LAN service.
With the application of the most advanced technologies like VoIP and LAN, the
OfficeServ 500 can connect various multimedia devices in offices where Internet is
actively used. The OfficeServ 500 is the up-to-date digital exchange system that can
be also used as the phone system or PABX system.
The OfficeServ 500 System can be composed of two types, OfficeServ-M and
