WIT-400HE Installation Manual Date: 15/M ar/2012 This Document Contains proprietary information and may not be reproduced or copied without express Written permission of a duly authorized representative of Ericsson-LG Co.Ltd. 9 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. Rank AP Max retry counter Simultaneous Call Reject afterFull Assoc Roaming MultipleSSID Power control WPA Best Cisco – AP1231G O 12 X O O O O Good Cisco – AP1121G O 10 X O O O O 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
WIT-400HE Installation Manual Date: 15/M ar/2012 This Document Contains proprietary information and may not be reproduced or copied without express Written permission of a duly authorized representative of Ericsson-LG Co.Ltd. 10Linksys 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
WIT-400HE Installation Manual Date: 15/M ar/2012 This Document Contains proprietary information and may not be reproduced or copied without express Written permission of a duly authorized representative of Ericsson-LG Co.Ltd. 11 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. No Item Description 1 802.11 b/g 802.11 b/g should be supported 2 Simultaneous call Minimum 4 simultaneous calls should be supported 3 Reject access when full traffic It can be adjusted in the admin program 4 Max retry counter It can be set in the admin program or should not be transmitted 5 Continuous call Long term call(longer 12 hours) should be supported 6 Roaming within same kind of AP Seamless handover/roaming should be supported 7 Traffic distance Longer than 200 meters 8 Antenna diversity More than 2 antennas9 AP manager AP manager can some configuration like channel, SSID, WEP key, and so on. 10 WDS Wireless Distribution System should be supported 11 External antenna Connector type should be supported 12 European CE Type Approval CE should be approved for European market13 USA UL Type Approval UL should be approved for USA market14 USA FCC Type Approval FCC should be approved for USA market 15 Canada CSA Type Approval CSA should be approved for Canada market 16 Korea MIC Type Approval MIC should be approved for Korea market 17 WiFi certification WiFi should be certified for mutual compatibility 18 RF power control Fixed power and auto power should be supported 19 DHCP, NAT DHCP and NAT should be supported 20 Price Low price 21 QoS Voice packet should be handled with high priority

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.

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
WIT-400HE Installation Manual Date: 15/M ar/2012 This Document Contains proprietary information and may not be reproduced or copied without express Written permission of a duly authorized representative of Ericsson-LG Co.Ltd. 14message 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. Cisco (1) Open a page “Network Interfaces > Settings” . You can see a edit box “DTIM”. (2) Enter 3. WIT-400HE

Cell Planning 5.1 Access Point Requirements To determine the number of Access Point in a system, you should consider Access Point broadcast range. 5.2 Access Point Range In a typical office environment, each Access Point has a broadcast range of 50 meters and supports an area of 8,000 square meters, but a broadcast range depends entirely upon office environment. Where the absence of any obstruction provides perfect line of sight conditions between the Access Point and wireless terminal users and if there are no atmospheric limitations, the range may increase to 200 meters. If you want to use AP supported 802.11b/g/n mixed mode, this range may decrease to 100 meters because of the characteristics of AP. The following Access Point broadcast ranges can be used as a rough guide to plan the Access Point positions: z In line of sight, the b/g Access Point has a range of up to 200m(open area). z In hall, the Access Point has a range of 40-70m. z In buildings, the Access Point has a range of about 25-40m. It assumes that walls are made of light brick, plasterboard or wallboard with metal frames. Normal electrical wiring, central heating pipes, office furniture and desktop computer equipment have no significant effect. <Figure .1> Access Point Service Area 5.3 Access Point Positioning The radio coverage area that a single AP provides is not sufficient to serve the entire WLAN in many

The solution is to increase the radio coverage area. A. RF channel Specification The IEEE 802.11 b/g standard establishes several requirements for the RF transmission characteristics of an 802.11 radio. These channels have a center frequency separation of only 5 MHz and an overall channel bandwidth (or frequency occupation) of 22MHz. So it has overlapping channels for each channel as shown in figure below. This is true for 802.11b products running 1, 2, 5.5, or 11 Mbps as well as the newer 802.11g products running up to 54 Mbps. B. Channel Allocation and cell planning When planning a WLAN cell, you should ensure that the channels that the adjacent APs use are non-overlapping. Non-overlapping channels are frequency bands that do not have a frequency that is common to each other. For example in the 2.4GHz range there are three channels that are non-overlapping (channels 1, 6 and 11). Therefore, when you deploy a secondary AP to extend the Radio coverage, you can use the channel 1 for the first AP, channel 6 for the next adjacent AP and channel 11 for the third AP as shown in figure below and then start with channel 1. If you use overlapping channels, radio frequency interference can occur, which leads to connectivity issues and in poor throughput. Also, you should ensure that you do not place the APs too close each other. Too many APs in the same vicinity create radio congestion and RF interference that can reduce data throughput. A careful site survey can determine the best placement of APs for maximum radio coverage and optimized throughput. 1 channel 6 channel11 channel1 channel 6 channel11 channel

QoS Checklist After you finish the installation of the system and AP, please check the voice quality by the following items. If you find any problem on the following list, you can improve QoS by the trouble shooting guide of each case. No. Check list Trouble shooting guide 1 Can you make 8 calls at the same time without voice break? (The AP should guarantee 8 calls simultaneously) - Review the cell planning - Check the channel of the adjacent APs. It should be separated more than 5 channels between adjacent APs. - If the AP is not in the recommended list, please compare with the recommended one. - If the above solution doesn’t improve the voice quality, please change codec type to G.729 in system admin. 2 Can you make long time call with good voice condition? - Review the cell planning - Check the channel of the adjacent APs. It should be separated more than 5 channels between adjacent APs. 3 Can you talk across the roaming area? (WIT-400HE guarantees roaming time less than 500ms in well designed WLAN network.) - Review the cell planning. The adjacent cell is overlapped enough? - Check the AP support seamless roaming. We don’t guarantee if it’s not the recommended one. 4 Can you talk without voice break moving in the office? - Review the cell planning. The APs cover all the area that you are moving? .- Check the AP connected with the phone.5 Can you talk comfortable with the outside subscriber? - Check the trunk status of the system. - If volume is too low, you can adjust gain in the system admin.
