4. Configuration: 3G Router Mode 4.5.1 Regulatory Domain Wireless Settings -> Regulatory Domain The Regulatory Domain decides what channels and Tx output power levels are available for your country. In most cases, the Regulatory Domain is already selected correctly for your country. Please note that using the wrong Regulatory Domain is strictly prohibited. If you live inside EU, you must use the ETSI Regulatory Domain. If you live in United States, you must use FCC domain.
4. Configuration: 3G Router Mode 4.5.3 Channel Wireless Settings -> Channel The channel is the frequency range used by radio. In 802.11g/b standard, there are maximum of 14 Channels. However, the available channels in each country are dependant on the local regulation. If you are living in Europe, you can use channel 1 to 13. If you are living in the United States, you can use channel 1 to 11. Each wireless channel takes between 22 to 25MHz of frequency width. But the channels are only 5MHz apart.
4. Configuration: 3G Router Mode Procedure to make encryption Step1: Select your SSID: If you have enabled the “Multiple SSID” function, there will be more than one SSID to choose from.

If you need to find the IP address, please go to Status->Client Table menu. Power Saving: Modulation: Show the which MCS level is used in 11n mode Channel Width: wdith. RSSI(dBm): The signal strength of the client device. Time(Sec): The connected time of the wireless client.
4. Configuration: 3G Router Mode Decline BA Request: Enable this option to decline the Block ACK requests by other devices. BG Protection: The 802.11g standard includes a protection mechanism to ensure mixed 802.11b and 802.11g operation. If there is no such kind of mechanism exists, the two kinds of standards may mutually interfere and decrease network’s performance.. Beacon Interval: The device broadcasts beacon frames regularly to announce its existence.
4. Configuration: 3G Router Mode must be transmitted following the RTS/CTS handshake exchange mechanism. The RTS threshold should have a value between 256-2347 bytes, with a default of 2347. It is recommended that this value does not deviate from the default too much. Short Preamble: A preamble is a signal used in wireless environment to synchronize the transmitting timing including Synchronization and Start frame delimiter.
4. Configuration: 3G Router Mode AC Type The queue and associated priorities and parameters for transmission are as follows: Data 0 (Best Effort, BE): Medium priority queue, medium throughput anddel ay. Most traditional IP data is sent to this queue. Data 1 (Background, BK): Lowest priority queue, high throughput. Bulk data that requires maximum throughput and is not time-sensitive is sent to this queue (FTP data, for example): Data 2 (Video, VI): High priority queue, minimum delay.
4. Configuration: 3G Router Mode Contention Window increases exponentially up to a specified limit Maximum Contention Window. The random delay avoids most of the collisions that would occur if multiple APs got access to the medium at the same time and tried to transmit data simultaneously. The more active users you have on a network, the more significant the performance gains of the backoff timer will be in reducing the number of collisions and retransmissions.
4. Configuration: 3G Router Mode 4.5.10 WDS Settings (Repeater) This is known as WDS Repeater function. Enable this setting to allow remote WDS equipped AP to extend the wireless signal of Air3G.

If encryption key is required, the AP will prompt you to enter the encryption information. 7.2.4 Advance Settings BG Protection: The 802.11g standard includes a protection mechanism to ensure mixed 802.11b and 802.11g operation. If there is no such kind of mechanism exists, the two kinds of standards may mutually interfere and decrease network’s performance..
7. Client Mode Channel Width: You can choose 20MHz or 20/40MHz channel width. Choose 20MHz for compliance with laws in some countries. 40MHz offers faster performance than 20MHz Guard Interval: Guard interval is placed at the beginning of each transmission. It is used to reduce the interference effect of multi-path transmissions. The use of long Guard Interval may perform better in interference or multipath environment. However, it can reduce the performance.

A set of protocols developed by the IETF to support secure exchange of packets at the IP layer. IPsec has been deployed widely to implement Virtual Private Networks (VPNs). IPsec supports two encryption modes: Transport and Tunnel. Transport mode encrypts only the data of each packet, but leaves the header untouched.
12. Wireless Network Glossary increase the receiver sensitivity and to focus available power at intended Rx. NAT Network Address Translation. A network algorithm used by Routers to enables several PCs to share single IP address provided by the ISP. The IP that a router gets from the ISP side is called Real IP, the IP assigned to PC under the NAT environment is called Private IP. Node A network connection end point, typically a computer. Packet A unit of data sent over a network.
