defined in 802.11h. European standards require that sites operating in the 5 GHz band must be able to control the transmission power of radio waves to avoid interference with other users using the 5 GHz band. Transmission Power Control also helps avoid interference with other wireless local networks. Transmission distance is a function of transmission power: the higher the transmission power of the site, the farther the transmission distance will be, and the more likely it will interfere with n

initialized by Usb_fill_bulk_urb () and submitted to the USB core, which is the 3rd, 4 steps of the USB read data operation process. In the Usb_fill_bulk_urb () function, initialize the URB completion function Usb_read_port_complete (), and the function Usb_read_port_complete () is called only when the URB commit is complete. The pseudo code is as follows:Static u32 usb_read_port (struct intf_hdl *pintfhdl, u32 addr, u32 cnt, U8 *rmem) {struct recv_buf*precvbuf = (struct recv_b UF *) Rmem;_adap

because recently do a smart home project, the first to communicate with the socket, in order to first use UDP to judge the intranet outside the network to establish links, and then use TCP real-time communication. first understand the definition Advantages of http://www.360doc.com/content/14/0325/09/1317564_363500997.shtml TCP: Reliable, stableTCP is a reliable embodiment of TCP in the transfer of data,

Huawei glory, a ZTE, a sister with a cool pie, aFake Android, all test OK. Two air conditioning tests are normal. Perfect! A large number of test processes have been found to be in the receiving area. Generally there is a 5M above, if you add some driving circuit effect will be better, but if not the effect of the result is very good. so Easy to put, so that we can use the phone as our external energy remote control. It's the home appliance. http://w

Common Raspberry Pi interface number is divided into two kinds of 26-pin a 40-pin, according to their own PI can!Pin definition is divided into two, the first is more common, the second relatively less use, at least I am, but in the next article will use the second serial communication definition!The first type of definition:The second definition:Three, Raspberry Pi GPIO pin identificationMany small partners may not know how to count Gpio pins and see!
