Dahua 5.8GHz Wireless AP/CPE User Manual 4. TDMA Currently, most long-distance wireless broadband network bridge products developed from 802.11 WLAN technologies. The built-in operation system integrated TDMA20M/40MHz bandwidth flexible configuration, rate control, Auto ACK-Timeout Adjust and several other industry-leading technology, which is an ideal product of long-distance wireless broadband access. Among those, TDMA effectively solved the problem of hidden node which bothers large-scale point-to-multipoint WLAN. 20M/40MHz bandwidth flexible configuration achieved a balance between scarce wireless bandwidth resource and complex working scenario: narrower wireless bandwidth configuration is used in the situation where there are less free wireless channels and a single user wireless access rate requirement is not high;
wider wireless bandwidth configuration is used under the situation where there are more free wireless channels and single user wireless access rate requirement is high. Besides the narrower wireless bandwidth configuration is more effective in the environment with block. Operation system adopts advanced rate control algorithm which can quickly adapt to channel quality change and at the same time keep the rate stable as much as possible, which is very suitable for long-distance wireless transmission. Auto ACK-Timeout Adjust technology can auto detect the distance between access point and client;
adjust wireless parameter to optimize the device performance. See Figure 12 for client TDMA. Figure 12 When you enable TDMA function, AP end needs to enable TDMA, client needs to set a priority. Different clients ask for different demand for bandwidth when one AP links to several clients, but the setting of priority is done according to clients demand of bandwidth for current device. We recommend users to set priority as high if the demand for bandwidth id high, otherwise, priority should be set as low priority. Anyway, all the clients priority can be set same if they have the same demand for bandwidth. Attention: The TDMA of AP and client should both be open when you want to enable TDMA function.

(3) The crystal head of network cable is insecure or cable sequence error (remake the crystal head) 2. Forgot IP address and unable to restore factory default Please press Reset button for 5-10 seconds, try to input 192.168.1.36 IP to log in the device after all the LED lights are on. 3. Why cant fine wireless access point in my computer?
Solution: wireless system is connected with max working rate, the exact rate depends on distance and
- 38 -
Dahua 5.8GHz Wireless AP/CPE User Manual environment. Users can detect the following steps to make sure the max possible connection rate is obtained.
(1) The location of wireless access point Try to adjust the location and direction of wireless access point.
(2) Wireless channel The interference could be obviously improved if you use other communication channel;
(3) Wireless interference Other devices may also cause interference, so try to shut off other devices and check if the situation is improved. Users also can shield the devices which cause interference or adjust the position. 4. The signal intensity is too low.
(1) It is not visible between CPE and AP due to bigger blocks.
(2) The surface plate of CPE doesnt face AP directly; the vertical angle between AP and CPE is not suitable.
(3) CPE is installed on the window, which may cause interference.
(4) The distance between AP and CPE is too far. 5. Why is the signal intensity high but the throughput capacity low?
Reasons:
(1) Too much interference or multipath interference.
(2) Something is wrong with the device Ethernet port. 6. Frequent packet loss, serious packet loss with several devices in the same area, it will be better when communication channel is changed. Same frequency interference will be caused if several DH-PFM88X are used in the same area without separate the channels of two devices. Users are recommended to separate the frequencies of them so as not to make the communication channels overlapped. It is recommended to make the frequency
- 39 -
Dahua 5.8GHz Wireless AP/CPE User Manual difference between two devices over 20M if the width of communication channel is 20M. 7. Packet loss and big time delay for ping device address of the computer
(1) Port isolation for AP which connects the same POE switch.
(2) Bad pressing and connection for cable crystal head (remake crystal head) 8. Users often lose connection and the speed is low.
(1) Too many users of AP access.
(2) Weak AP signal.
(3) Too many serious interference signals in the surrounding, client and AP are not binded.
(4) Check user number and if the upper level network bandwidth is already full. 13. Construction attention for wireless bridge and monitoring. 13.1 Construction attention 1. The horizontal direction and vertical angle of antenna Try to make the AP antenna on the base station slope down a certain angle because the antenna between base station and wireless bridge is directional. Meanwhile, try to make AP and client antenna aim each other horizontally. 2. Height for setting antenna There are some certain requirements for the distance between two points and height for setting antenna during the actual wireless communication between two points due to the fact that the earth is a sphere. Please refer to the following sheet for more details. Frequency 5.8GHz 3Km 5m 5Km 7m 10Km 11m 15Km 16m

Dahua 5.8GHz Wireless AP/CPE User Manual 3. Geographical environment Place for the farthest distance of communication is sea level and clear flat land, which is the generally-used geographical condition to evaluate the communication distance of wireless communication devices. The second farthest are places like rural area, hill, riverbed and other half obstacle, half open environment. The shortest communication distance is place like city building complex or among mountains. In a word, the more intensive the obstacles are, the more influence it will cause to wireless communication distance, especially to metal objects. Therefore, make sure the client and access point are directly visible during the actual construction;
4. Electromagnetic environment Direct current dynamo, grid system, switching power, electric welding machine, high frequency electronics, computer, single chip and other devices all can cause different levels of influence to communication distance of communication devices. 5. Climatic condition The communication distance will be longer if the air is dry; the communication distance will be shorter if the air is wet (especially rainy, snowy weather) 6. Try to avoid same frequency and adjacent frequency interference Users need to search what frequencies that other devices are using first when setting the frequency of access point, which has to avoid these frequencies as far as possible. Meanwhile, the access point frequency has to be separated a certain distance from the surrounding frequencies which are being used in order to prevent adjacent frequency interference. For example, when communication channel width is 20M, so it has to be separated over 20M from the frequency being used. Meanwhile, the frequency between each AP should be set like this. 13.2 Test Situation Testing distance: 3.5 km Test environment: The test place is located between Beicai Town and Zhangjiang Town in Pudong New
