1. DBMDBM is the absolute value of power. The formula is: 10lgp (power value/1 MW ).[Example 1] If the transmit power P is 1 MW, it is converted to dBm and then 0dbm.[Example 2] for 40 W power, the converted value in dBm unit should be:10lg (40 W/1 MW) = 10lg (40000) = 10lg4 + 10lg10 + 10lg1000 = 46dbm. 2. DBI and DBDDBI and DBD are the obtained Gain values (power gain). Both are relative values, but the reference standards are different. The reference of DBI is a full-direction

relaxing. The middle of the front-row central armrest is placed in the middle of the front-row seat, while the majority of the back-row central armrest is a foldable armrest, placed in the center of the back-to-back. ●Body Color It is the color of the vehicle body painted at the factory. We usually divide the color of the body into three categories: monochrome, two-color, and color trim. Currently, most cars are in a single color (also called the same color), while Mini and smart cars are in

BRF6100 is the TI company recently introduced to follow the Bluetooth V1.1 standard wireless signal transceiver chip, its upgrade model BRF6150 support V1.2 Standard, BRF6100 main features are: Digital wireless processor in-chip DRP (Digitalradioprocessor), CNC oscillator, Chip RF transceiver switch switch, bui

channel. This frame structure is subdivided into several time slots. In the TDD mode, it is easy to switch between the upper and lower links flexibly. The salient advantage of this pattern is that the time slot allocation between the top/downlink links can be changed by a flexible conversion point to meet different business requirements. In this way, using TD-SCDMA technology, all 3G symmetric and asymmetric services can be realized by changing the switching point of the upper/down link flexibl

think that dbm is the maximum value of 0, meaning that the receiver of the transmitter launched all the wireless signal received, that is, the wireless router fired how much power, the reception of the wireless network card to obtain how much power. Of course, this is measured in an ideal state, in practice, even if the wireless network card next to the wireless router transmitter antenna will not achieve the effect of dbm 0. So the measured dbm val

one, human factors The distance between the wireless router and the network card is too long, in this case can only be solved by a different configuration of the appropriate antenna. The wireless router and the network card have the obstacle influence, sometimes also can cause the disconnection breakdown, for instance the indoor complex environment, the wall, the furniture influence. So try not to go through walls over three floors as much as possib

multi-dimensional transmission scheme: one single RF channel is used to send and receive two or more signal streams. As a result, the wireless communication system can transmit data twice or more in a channel. In the system, use more than one high-integration RF upconverter) and antenna to transmit these multiple signals, and there is also more than one high-integration RF downconverter) and the antenna to

If nearby neighbors use the same channel as ours, our wireless signals will be affected. We can also use the Network Stumbler software for scanning to see which wireless signals exist nearby and which channel is used. Then modify our own wireless channels to avoid duplication with other channels. In addition, you should note that the signal of a channel will interf
