The difference between 300M and 450M for a wireless router The 150M, 300M, 450M, and other parameters of the wireless router refer to the maximum bandwidth, in Mbps, that is, 150Mbps, 300Mbps, and 450Mbps. This parameter refers to the maximum speed at which all wireless devices connected to the router send and receive data at the same time. 300M router, supports 300mbps=37.5mb/s maximum data exchange speed

From the past few weeks, the first batch of 802.11AC wireless products have started to be listed. In essence, 802.11AC is the current smartphone and notebook computer mainstream 802.11n standard enhanced version, simply from the download speed can have a significant increase, or even to the original 802.11n several times the speed. The working principle of 802.11AC 802.11AC core technology is mainly based on 802.11a, continue to work in the 5.0GHz band to ensure backward compatibil

The router's M is the short name of Mbps, the bit rate is used to describe the speed of data transmission of a unit, the greater the bit rate, the faster the data flow. Theoretically 150Mbps speed, the rate of transmission per second is 18.75mb/s. 300Mbps speed, the rate of transmission per second is 37.5mb/s, then how are these calculated? Note: The velocity of the data is variable, and the bit rate is only an average reference value. 1M speed, theo

Connect the Wireless Music box with the old speakers, using the iphone, Android phone, pad Music app, through the Airpaly, Dlan, Qplay function can push music to play on the speakers. At the same time, a wide range of compatible music App,ios support Baidu Music, QQ music, Watercress FM, cool dog mu

speed, respectively, corresponding to their respective protocols: 11Mbps (802.11B), 22Mbps (802.11 Super B), 54Mbps (802.11g/802.11a), 108Mbps (802.11 Super G), 125Mbps (802.11 high Speed-g), 300Mbps (802.11n). 11Mbps (802.11B) is the slowest of all wireless and, of course, the most popular wireless protocol, supported by almost all wireless routers and wireless cards. This protocol is included in most network adapters with 802.11G protocols. Unless

As shown in the following illustration: Solution: If you encounter this problem, you can set it below and the connection speed can be increased to nearly 300Mbps. 1. Set the wireless router to use channel binding (40MHZ). By implementing channel binding on a wireless router, routers can use 2 channels at the same time (the default is 20MHz). Channel bindings are also referred to as blending modes. 2. The following ada

In the 2.4G encounter bottleneck, the IEEE snow of 5G again mountain. At this point the 5G signal poor, through the dual-frequency design has been well resolved. Starting from the 802.11n in 2009, Wi-Fi devices support both 2.4G and 5G dual-band. The 2.4G is backwards compatible with old equipment, ensuring good wall signals and 5G for faster speeds.

generally stipulate only the transmission range and maximum transmission power of the signal. For a system operating on a global scale, its chosen band must meet all the requirements at the same time so that any user can access it, so the required elements must be minimized. In the case of satisfying the rule, the wireless frequency band can be freely connected, at this time, the anti-interference problem becomes very important. Because the 2.45GHZ ISM band is open band, use any of these freque

the points, the information extraction will not be affected. The data transmission rate of OFDM is also related to the number of subcarriers. Subcarriers In the OFDM system can select modulation modes based on the channel conditions and switch between modulation modes. The principle of selection and switching is the balance between spectrum utilization and bit error rate. In general communication systems, in order to maintain a certain degree of reli

type of the phase parameter. When the phase parameter response is used, the receiving and sending frequency of the server must be strictly multiple. ③ BeaconType: The radar only receives signals sent by the signal receiver on the aircraft, and can only capture the target.In order to expand the measurement range of the flight area, multiple radars are often configured along the navigation area column to achieve the tracking and measurement of the target, which is called the radar chain, that is

frequency domain description (spectrum). in engineering practice, the signal must have a stable time domain description within the period of symbol, that is to say, the frequency domain description of a signal changes with the change of the symbol cycle, and there are different stable descriptions in different symbol periods. 3. In both theoretical analysis and engineering practice, it is assumed that the signals in the time domain are cyclical and t

Ultra-Wideband Wireless Technology is favored by more and more emerging wireless technologies due to its high transmission rate, low power, and small scale features. However, its very high modulation bandwidth (usually higher than 500 MHz) and relative bandwidth (> 20%) pose many challenges to the development and testing of the ultra-wideband product. The traditional general testing method is insufficient in the face of the physical layer characteristics of UWB.First, signal reception and analys

802.11ac has made great strides in improving Wi-Fi performance by using a wider channel, a more efficient modulation mode (by transmitting data in RF waves), and multi-user connections (so-called multi-user MIMO. In fact, this kind of progress will come in a wave in the future. However, the new 2nd wave chip is different from the 1st wave device (please read the hardware upgrade) Remember that not all 802.11ac access points are the same. Many access points using the Broadcom chip are limited, fo

In the data communication system or computer network system, the bandwidth or capacity of the transmission media will often be greater than the demand for the transmission of a single signal, in order to effectively use the communication line, hope that a channel simultaneously transmission multi-channel signals, this is called Multiplexing Technology (multiplexing). Multiplexing technology can combine multiple signals to transmit on a physical channel, which can greatly save the installation an
