More and more routers begin to adopt modular management and upgrade. The advantage of this is that their products can be reasonably restructured according to different user needs, so that the product can play the maximum effect, in addition, the customer can invest the minimum amount of money to win the customer's approval. 1. Mature Wi-Fi solutions such as WLAN802.11n and 802.11ac can be integrated into access product devices through its integrated PCIe interface and corresponding driver softwa

How can the three major carriers innovate their networks when they face the "4G 4G" challenge? 4G development in 2015 is about to enter the fourth quarter. At the latest "LTE Network Innovation Seminar" sponsored by the TD Industry Alliance, a group of the latest statistics published by the Secretary-General of the TD Alliance shows that, with the three major carriers working together to build 4G networks and accelerate 4G commercialization this year

December 4, the Ministry of Industry issued a notice that to China Mobile, China Telecom and Unicom issued "lte/fourth generation digital cellular mobile communications Business (TD-LTE)" Business license. Thus, China's formal entry into the 4G commercial era. According to the Ministry of Public announcement, China Mobile, China Telecom and Unicom have access to td-

realizes by FFT. More descriptions will be made in the sections below.According to the ancient tradition, F represents the frequency domain, F represents the time domain, so can be seen from Equation 1-2, the amplitude of the modulation above each sub-carrier, is the frequency domain information. A similar argument is that OFDM transmits a frequency domain signal. This is a bit awkward, but many tutorials or articles use this way of explaining how the reader understands it. If purely from the f

modulation above each sub-carrier, is the frequency domain information. A similar argument is that OFDM transmits a frequency domain signal. This is a bit awkward, but many tutorials or articles use this way of explaining how the reader understands it. If purely from the formula or sub-carrier view, this statement is actually very straightforward elaboration.The above 1.1-1.3 extension, as shown:Figure VII: The OFDM system diagram on the time domain1.4 Is there another step? Actually, there is.

The Internet of things wireless communication technology, mainly divided into two categories: ZigBee, WiFi, Bluetooth, Z-wave and other short-distance communication technology, the other is Lpwan (low-power wide-area Network, low-power WAN), that is, WAN communication technology. Lpwa can be divided into two categories: one is working in the unlicensed spectrum of Lora, Sigfox and other technologies, the other is working under the authorization spectrum, 3GPP support 2/3/4g Cellular communicatio

The 4G era is already coming, and for users, 4G means faster transfer speeds and a better mobile network experience. But for operators, how to deploy 4G has become a big problem. As we all know, 4G LTE is now the most advanced mobile broadband solution in the world and the fastest-growing wireless communication technology in history. For operators, in order to occupy a place in the 4G era, in addition to actively promote
