1. Good anti - jamming ability Super low frequency power supply interference, electrical spark interference, inverter motor interference, control signal interference etc. that below tens of kilohertz are found in the elevator environment, the use of WIFI high-frequency transmission, can effectively avoid the interference of elevator environment. At the same time the device supports extended frequency, can avoid the same frequency interference in the traditional WIFI. 2. Short construction period In the absence of a large amount of wiring work, so greatly shorten the construction period, save a lot of human resources. 3. Embedded TDMA technology NZC110-EXT devices is embedded with TDMA technology, 20M/40MHz bandwidth, intelligent rate control, Auto ACK Time-out adjust. It makes thedevice have longer transmission distance, higher throughput and better point-to-multi-point performance. 4. Embedded hardware watchdog NZC110-EXT is embedded with hardware watchdog, which is used to monitor the working status of the device. Once the system is not working properly, the device can be rebooted to guarantee the stability of the system. 5. More Non-standard channels availability Currently most of the WIFI devices are working at standard 802.11 2.4GHz frequency. However, standard 802.11 2.4GHz only provide limited channels, and there is serious interference if there are a lot of 2.4GHz WIFI devices nearby. NZC110-EXT support more channels near 2.4GHz band, and spread the band to non-standard frequency part. The advantage of working at the non-standard band is to avoid the interference in the standard channels, and the wireless throughput can be improved. 2 User Manual of NZC110-EXT Note: Please confirm whether those non-standard channels are permitted locally before using them. 1.2 Electrical Specifications NZC110-EXT electrical specifications as shown below:

Mode: You can keep the default 802.11g+n mode to guarantee optimal transmission rate. 32 User Manual of NZC110-EXT HT Mode: Channel width selection, the device supports 20/40+/40-MHz bandwidth. In general, the wider the bandwidth is, the greater the data throughput rate. Max Transmission Rate: it can be used to limit the max transmission rate of a device. Click on Device Configuration->Advanced Settings, you can configure the advanced settings of the device in this section. Figure 5-21 Advanced Settings Country CodeDifferent countries allows different channels, you can choose the country code to allow the device works at the channels only permitted in the particular country. When you set Compliance Test mode, the frequency will extend to 2312-
2732MHz. Aggregation: It enables several data frames of 802.11 to be aggregated and transmitted out, thus improve the throughput. The larger the set value, the higher the throughput. 33 User Manual of NZC110-EXT VAP Isolation: The device supports multiple VAP; if this feature is enabled, and when the client1 is connected to VAP1, the client1 will not be able to communicate the client2 which is connected to VAP2. TDMA Currently, most of the outdoor bridge products are developed based on 802.11 protocols, however, it has the limitations of short-distance, hidden node problems, and poor point-to-multi-point performance. TDMA technologies developed and patented by Tongda, utilizing a series of advanced technologies such as TDMA, intelligent rate control, Auto ACK Time-out Adjust, having the advantage of long transmission range, high date rate and robust transmission. TDMA technology solves the problems of hidden-node problem in the 802.11 network infra-structure. Intelligent rate control algorithm can be adapted to quick channel quality variations, while stabilize the wireless throughput, thus suitable for long-distance transmission. ACK Time-out Auto Adjust can automatically detect the distances of the devices, and adjust the wireless parameters to achieve the best link quality. To use the TDMA, the user needs to enable TDMA mode in the AP device, and set a priority level in the station device. When several stations are connected to one AP, different clients demand different throughput. If the client demands higher throughput, its priority level can be set to High, otherwise set to Low. When the client demands the same throughput, their priority level can be set to the same level. Note: When using TDMA mode, the TDMA button need to be enabled at AP devices in the web-based configuration menu. The devices from other vendors cannot be connected to NZC110-EXT in the TDMA mode. When TDMA is enabled, your phone or laptop cannot be able to connect to the device. Auto ACK-Timeout AdjustIt is suggested to enable this function, so that the distance between 2 devices can be detected and all the related parameters can be optimized to achieve the best link quality. 34 User Manual of NZC110-EXT 5.2.2 Interface Configuration Per network settings like encryption or operation mode are grouped in the Interface Configuration. Figure 5-22 Interface Configuration General Setup ESSID: Name of a wireless. It is used to control the access to the wireless network, only the same ESSID can communicate with each other to establish a local area network. Mode: There are totally 4 wireless modes, including: Client, Access Point, Client (WDS) and Access Point (WDS). Access Point: Access point. Client: A client device that can connect to an AP. Client (WDS): Use WDS feature to link multiple APs in a network, all associated stations from any AP can communicate with each other like in ad-hoc mode. Client (WDS) means this device is a client in WDS mode. Access Point (WDS) Use WDS feature to link multiple APs in a network, all associated stations from any AP can communicate with each other like in ad-hoc mode. WDS AP means this device is an AP in WDS mode. Network: Choose the network(s) you want to attach to this wireless interface or fill out the create field to define a new network. 35 User Manual of NZC110-EXT Hide ESSID: to hide the broadcast name of the wireless network to avoid being connected to others. Check this function; others will not be able to search the SSID. Figure 5-23 Interface Configuration Wireless Security Security: User can set the security based on needs to guarantee the wireless security. The wireless encryption of the device to be connected to each other must be set to the same encryption. Figure 5-24 Interface Configuration MAC Address MAC - Address Filter: used to control communication between the device and other devices. Allow listed only: only the list of devices that are allowed to connect to the access point and the other device does not allow access to the access point. Allow all except listed: allow the device to connect to the access point outside the list, and the other device does not allow access to the access point. 36 User Manual of NZC110-EXT Figure 5-25 Interface Configuration Advanced Settings Station Isolation: Enable this function, STA cant communicate with each other. Max Station Limit: You can set the number of STA that connect to AP.
Firewall The firewall creates zones over your network interfaces to control network traffic flow. The default settings of firewall zone as shown below. 37 User Manual of NZC110-EXT Figure 5-26 Firewall Click "modify" or "add" to define the generic properties of the zone. In the port trigger section, the forwarding rules for the current area and other areas can be modified. For example, click on Edit button of LAN zone; as shown below, this section defines common properties of "lan". The input and output options set the default policies for traffic entering and leaving this zone while the forward option describes the policy for forwarded traffic between different networks within the zone. A covered network specifies which available networks are member of this zone. 38 User Manual of NZC110-EXT Figure 5-27 Zone The options below control the forwarding policies between this zone (lan) and other zones. Destination zones cover forwarded traffic originating from "lan". Source zones match forwarded traffic from other zones targeted at "lan". The forwarding rule is unidirectional, e.g. a forward from lan to wan does not imply a permission to forward from wan to lan as well. Figure 5-28 Inter-Zone Forwarding
VLAN VLANs are often used to separate different network segments. The VLAN function allows user to create multiple virtual local area network. As shown in figure, we add a VLAN on port ath0 (wireless network port). The VLAN ID is 10. The range of VLAN ID is 2~4094. Each VLAN ID represents a different VLAN. 39 User Manual of NZC110-EXT Figure 5-29 VLAN Settings Bridge function is needed to use together with VLAN. As show below, we add VLAN 10 on port eth0 and ath0, they are eth0.10 and ath0.10 Figure 5-30 Add VLAN ID Then we create a new interface and put eth0.10 and ath0.10 into the same bridge in Network->Interfaces page as shown below. 40 User Manual of NZC110-EXT Figure 5-31 Binding VLAN Interfaces The packets from eth0.10 or ath0.10 will be added a VLAN label which ID is 10. That requires: the opposite wireless connection side must support VLAN 10, the device which connects with eth0 is also need to support VLAN 10 (such as a VLAN Switch). Common connection mode as shown below:
