802.11n, 2x2 MIMO, and 20 MHz frequency bandwidth: 144 Mbit/s.802.11n, single MIMO, and 20 MHz frequency bandwidth: 72 Mbit/s.For 802.11n/ac, the maximum speeds supported in different MIMO modes and at different frequency bandwidths are as follows: The maximum transmission speed supported by a wireless router is subject to the wireless protocol it supports. Frequency band: 2.4 GHz and 5.0 GHz (5.0 GHz is optional and is a future trend.).You can check its wired interface parameters in Interface Description > GE electrical interface in the Huawei ARS Product Documentation. To transmit traffic at a speed of higher than 100 Mbit/s, the router must have a 1000 Mbit/s interface.įor wired interface parameters supported by AR routers, check the router product documentation or official website. Table 1-2 Hardware requirements for the 100 Mbit/s WiFi speedĪ 100 Mbit/s interface can transmit only traffic at a speed of lower than 100 Mbit/s. When the theoretical WiFi speed is 200 Mbit/s, the theoretical WiFi download speed is 25 MB/s. This speed refers to the speed for file downloading or video streaming by STAs, in MB/s.Īs 1 byte equals 8 bits, the theoretical WiFi download speed and the theoretical WiFi speed are in the proportion of 1:8. If the downlink speed is 200 Mbit/s and the wireless link speed is 150 Mbit/s, the theoretical Wi-Fi speed is 150 Mbit/s. The theoretical Wi-Fi speed is the smaller value between the downlink speed and the wireless link speed. This speed refers to the maximum data transmission speed when a STA accesses the Internet through a WLAN, in Mbit/s.
After they set up a wireless link, they will negotiate the wireless link speed to 150 Mbit/s. The wireless link speed is the maximum transmission speed that is supported by both the STA and router.Īssume that a wireless router supports a transmission speed of 300 Mbit/s and the wireless network adapter of a STA supports a transmission speed of 150 Mbit/s. After a STA connects to a WLAN, it negotiates the wireless link speed with the associated wireless router, in Mbit/s. This speed is also referred to the wireless link speed, as shown in Figure 1-2. Wireless link speed negotiated between a wireless router and a STA When a user subscribes to a 200 Mbit/s broadband package, it means that 200 Mbit/s is the downlink speed. In this document, the downlink speed is the bandwidth that a user subscribes to from a broadband carrier. Table 1-1 List of terms related to the WiFi speedĪs shown in Figure 1-2, the downlink speed is the speed at which the Internet sends traffic to you for such services as browser opening or file downloading, and is expressed in Mbit/s. Info: system is rebooting ,please wait.įor details about how to log in to an AR router using the CLI, see How to Log In to the AR Router Through the Console Port (CLI) and How to Log In to the Router Through the Mini USB Port (CLI) in How to Log In to an AR Router Through the Web and CLI. Warning: The WorkMode Change will be activated after board reboot. If the AR router does not work in Fat AP mode, run the set workmode wlan command to set the working mode to Fat AP.Wlan Config WorkMode = ap // ap indicates the Fat AP mode, and ac indicates the AC mode. If you are not sure whether the default configuration has been modified, log in to the router and run the display workmode wlan command to check its working mode.By default, an AR router with the letter W contained in its model name works in Fat AP mode, and that without the letter W contained in its model name works in AC mode.
