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-

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 domain　　1.4 still have this step? Actually, there is. "Small white" you can think first, the unexpected words first look down,

Actually, there is. "Small white" you can think first, the unexpected words first look down, because this needs to be considered in the frequency domain, so I wrote in the back. "also refer to [1]"The above-mentioned time domain analysis with LTE implementation, the followi

Nginx If support =,!= logical comparison, but does not support if This example uses the Set-misc-nginx-module Copy Code code as follows: Location =/test/{ Default_type html; Set_random $a 0 9; # $a randomly fetched from 0-9 if ($a Echo ' A: $a is LTE 4 '; } if ($a >= 5) {# $a if > 5 that's the wrong notation.

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

today, let's elaborate on the evolution of GSM,TD to LTE :Let's take a look at the next evolution:2G,3G network in the architecture has four physical devices, LTE in the network architecture only eNodeB and access gate two physical devices, removed the original 3G network support circuit switching (circuit-switch) function, transform the IP routing network of the packet, The complexity of the core network i

1. Create an array In programming languages, values and strings are called scalar variables, and a scalar variable can only represent a single numeric value or string. For example, $YDTX = the variable $ydtx in "mobile communication" is a scalar variable, and how do we use a variable to represent multiple values or strings in practice? For example, how to express "Communication base", "communication equipment", "Test Optimization", "3G", "LTE" and man
