The WIT-400HE is only 802.11b/g compliant, its maximum frequency is 2.4GHz and 54 Mbps maximum
bandwidth. For more detail information of cell planning, please refer to the manual of AP.
1.3 Access Point
The following is a list of APs that have been made an imperative experimentation with the WIT-400HE
and the result.

counter
Simultaneous
Call

Full Assoc Roaming Multiple SSID

Max retry counter : It’s the maximum retry counter of data packet from AP to client. If the retry counter
of a packet exceeds the limit, the packet is discarded. If the AP don’t support max retry counter, it can
make network busy by excessive retransmit when a user goes to out-of-range in conversation.
When the receiving packet rate is very low during 10 seconds, WIT-400HE disconnects the call to prevent
excessive retransmit of packets.
The simultaneous calls are estimated in idle network configuration, so it can be decreased by the
network condition. When the AP is commonly used for data and voice, the bandwidth for voice call will be
decreased. If you use overlapping channels, radio frequency interference can occur, which leads to
connectivity issues and in poor throughput.
Reject after Full Assoc. : This feature support to restrict the number of association simultaneously for
load balancing.
Roaming : It means that the call in conversation is not disconnected when it reams to other AP. To
support seamless roaming, the signal range of each AP should be overlapped.
If you need to use roaming feature, we strongly recommend Cisco AP. The other APs above support
roaming but they are unstable. We received report that the phone is muted sometimes after roaming with

Linksys AP. We found that sometime the AP doesn’t send packets after roaming in our laboratory
investigation.
O : We strongly recommend.
∆: It supports roaming feature, but it’s unstable or not verified enough.
X : It doesn’t support roaming feature.
Multiple SSID : The AP supports multiple SSID.
AP TX Power Control : It can control the signal range of AP. It’s very important to install multiple APs in
small area. The frequency of adjacent APs is overlapped too much, you can decrease the transmit power
to reduce the interference of radio frequency.
WPA : It make wireless network more securely protected. It authenticates with the server and changes
the encryption key dynamically.
IPOne AP is made in Korea.
Note: In case using AP supported 802.11n, we recommend Cisco Aironet 1250 Series AP. However, you
must reconsider cell plan include because of the characteristics of 802.11n MIMO AP. We recommend
you contact the Access Point technical support team
1.3.1 Which one is better
Depending on the internal implementation of IEEE802.11b/g protocol inside of the APs, roaming across
two contiguous regions may be affected. Cisco is currently showing most optimized seamless roaming.
CISCO APs are strongly recommended to customers. IPOne is estimated that it’s less than CISCO
but it performed good as we can recommend. Other APs did work well in low traffic, but it’s
unstable in high voice traffic, more than 8 calls simultaneously. Other APs also don’t support
transmit power control.
If you need to use multiple APs, we strongly recommend Cisco AP. The other APs are unstable for the
roaming feature.
The most important thing to select AP is the environment of the site to install. The number of
simultaneous voice call should be considered carefully to support stable voice quality. We also
recommend that the association number of an AP doesn’t exceed 30 clients to prevent poor voice quality.
We can suggest as follows in each conditions.
(1) 20 ~ 30 clients in an AP (less than 12 calls simultaneously)
A. Cisco-AP1231G
(2) 10 ~ 20 clients in an AP (less than 10 calls simultaneously)
A. Cisco-AP1231G
B. Cisco-AP1121G
(3) Less than 10 clients in an AP (less than 8 calls simultaneously)
A. Cisco-AP1121G

1.3.2 How to set up multiple APs
Our recommendation is that one AP(Access Point) is used for one cell area. If you would install
more than two APs for a cell, we recommend you to use the same SSID for each AP. And the APs
should have different RF channel far away than 5 channels each other. For example, AP1 has RF
channel 1, then AP2 should have RF channel 6. If the RF channel number of the APs is overlapped
near within 5 channels, the retransmission for data communication may be increased. As the
result of this the standby time of WIT-400HE may be decreased and the voice quality will be very
poor. So, you should check this carefully.
If you want to increase the capacity of wireless network by increasing APs, you need to control
the transmit power level of APs not to overlap too much. If the radio frequency is overlapped too
much, it can decrease the throughput of the APs.
Please refer to “6. Cell Planning” chapter to get the detail information for installing multiple APs
1.3.3 Recommended AP specification for WIT-400HE
There are many kinds of Access Point in the world. To recommend proper Access Point for WIT-400HE,
LG-Ericsson specified as the following. An Access point has more satisfied item, it is better to WIT-400HE.
When you purchase an AP, you’d better to refer to this list.

1.4 iPECS System
The iPECS System is a call controller of the WIT-400HE. WIT-400HE can be registered within a same
LAN subnet or other subnet which is routed to the system network.
2. Wireless Environment Setup
This section describes AP(Access Point) configuration for normal operation of WIT-400HE. The AP
should be plugged into a switch/hub for connectivity with the subnet of office.
2.1 Basic IEEE 802.11b/g network diagram
The following figure exhibits network infrastructure of 802.11b/g compliant network diagram.
APs are connected to a HUB in subnet, since WIT-400HE is able to access the Internet. The iPECS LIK
and WIT-400HE system work on top of this context.
2.2 Where iPECS System is positioned in the 802.11b/g network.
The following is a basic configuration of IEEE802.11b/g environment to enable WIT-400HE and the
iPECS System.

(1) WIT-400HE / AP:
- IEEE 802.11b/g network
- SSID / DTIM interval configuration within AP
(2) AP / iPECS LIK:
- Direct connection : AP PoE of iPECS System
- Indirect connection : AP HUB PoE of iPECS System
2.3 AP Configuration
Depending on vendors of AP, the following two parameters should be carefully set up.
2.3.1 SSID
SSID is for authentication use. An AP can have an arbitrary SSID value for example “wireless”. In this
case, WIT-400HE with “wireless” SSID can communicate with that AP. It is important to use accurate
SSID on both WIT-400HE and AP.
Recommendation)
(1) If you are free of security, please just use one SSID for all APs and WIT-400HE.
(2) If you are using WIT-400HE in a wireless environment with predetermined SSID, please
change the SSID of your WIT-400HE.
2.3.2 DTIM (Delivery Traffic Indication MessageData Traffic Indication Map) & Beacon
DTIM is related to an interval of packet transmission. By an inherent nature of the iPECS LIK, WIT-400HE
frequently uses multicast message for the communication with the iPECS LIK. The delivery of multicast

message is affected by the DTIM parameter.
Beacon is an indication of packets buffered in AP which are to be delivered to each wireless station, WIT-
400HE. The information of DTIM is contained in a beacon message. Therefore, DTIM configuration can
be affected by the beacon interval. The following is illustrating the relationship of beacon and DTIM:
Recommendation)
(1) DTIM should be less than 200 msec.
(2) If AP doesn’t support DTIM configuration, more special care needs to be taken for Beacon
interval setup. Otherwise, Use the smallest DTIM interval that AP can support.
2.3.3 Configuration
This section enumerates how you set up both SSID and DTIM in AP.
