I believe many of my friends have heard of MIMO wireless technology, which marks the 802.11n technology. Its Reference improves the existing network performance, increases the throughput, and increases the capacity. The principles of this document are described in detail. A mimo (Multiple-InputMultiple-Out-put) system is a technology used for 802.11n. 802.11n is the next generation 802.11 standard and can i

MIMO technology can be used as a bridge to connect old and new wireless technologies, so that the two can develop and integrate harmoniously. So it is already an important technology in the next generation of wireless broadband mobile communication systems. The following will give you an in-depth analysis of its development. MIMO technology has become one of the key technologies in the wireless communicatio

Major advantages of 802.11ac: multi-user MIMO The one thousand Mbit/s Wi-Fi technology of 802.11ac means faster speeds for Wi-Fi clients than 802.11n. 11ac is actually composed of several important technologies, including the multi-user MIMO technology. 11ac is divided into two phases: Wave 1 and Wave 2. It is expected that 11ac will implement Wave 2 in the second half of this year, while multi-user

MIMO technology can greatly improve the coverage range and transmission rate of WLAN. When multimedia applications with low latency and high bandwidth requirements, such as home broadband network connections and real-time HDTV wireless communication, and applications with scattered and shared content for entertainment devices become more and more common, wireless communication technology is also required to improve its efficiency under the condition o

LTE user documentation(if there are inappropriate places, please correct me!) )9 PHY Error ModelThe physical error model consists of a data error model and a downlink control error model, both of which are activated by default. You can use the Ns-3 property system to activate, specifically:Config::setdefault ("ns3::ltespectrumphy::ctrlerrormodelenabled", Booleanvalue ( False)); Config::setdefault ("ns3::ltespectrumphy::D ataerrormodelenabled", Booleanvalue ( false));Ten

The combination of MIMO and OFDM technologies is considered as the core technology of the next generation high-speed wireless LAN. This paper comprehensively analyzes the application of MIMO and OFDM technology in Wireless LAN, discusses the key technologies of MIMO and OFDM, and looks forward to its development prospects. 1. Introduction As a new communication

NXP Semiconductors, formerly known as Philips semiconductor, has announced that the company uses a full range of transceiver products using WiMAX 2x2 MIMO (Multiple Input Multiple Output, Multiple inputs and Multiple outputs) technology, this series of products is specifically designed for mobile and handheld applications. To fully support the adoption of mobile WiMAX technology, the new series of NXP Semiconductors adopt 2x2

MIMO is called multi-input multi-output.First, let's look at the concept of gain and how to calculate it:There are two important concepts in spread spectrum communication systems: processing gain and anti-interference tolerance.Processing gain is used to illustrate the improvement of signal-to-noise ratio of communication system, and is a performance index of system interference. Generally, the ratio of the spread spectrum signal bandwidth W to the in

"Note one: Single-carrier and Multicarrier transmission"MIMO-OFDM technology is the key technology of 3g-lte,wimax communication system and WLAN such as ieee802.11a,ieee802.11n and so on, as a communication dog, these should be knowledge that must be mastered. However, the undergraduate communication course is boring and disconnected from the actual system, in class, the teacher always lists a lot of professional terminology, what is said, but the con

The multiple input multiple output (Multiple-input, Multiple-output;mimo) technology provides an excellent way to extend the range of the Wireless area Network (WLAN), and has recently become the focus. MIMO technology began in 1985, but only now applies to wafer-level devices to dramatically improve transmission range and capacity. Since MIMO is not a single co

802.11n Frequently Asked Questions While 802.11n technology brings enormous benefits in terms of increased coverage, throughput and capacity, it also requires careful planning and optimization for organizations to fully realize its benefits. this comprehensive FAQ attempts to demystify 802.11n and offers guidance on important issues facing organizations with regards to 802.11n adoption. General Q: What is 802.11n?IEEE 802.11n is the next generation wireless LAN standard. the excitement about 802

combination of cooperative diversity technology and MIMO technology. This article analyzes network coding in wireless networks and other application technologies from the perspective of physical layer, such as combining them with MIMO, making full use of redundancy and improving system throughput, based on the complex environment of the network in the future, this paper describes its further research direc

communications--mimo (Multiple-input Multiple-output, more than one) To take a look at an example, someone said, why I bought a new 3-day cable support 802.11AC protocol wireless router, resulting in signal strength, coverage and even speed did not go up? Not enough antennas? I'm telling you, 300 is useless, check your acceptance terminal support does not support AC Agreement bar. For example, you use the iphone 3, this phone can only support 11a/b/

5G has high performance, low latency and high capacity characteristics according to 3GPP definition, and these advantages are mainly embodied in millimeter wave, small base station, massive MIMO, Full-duplex and beamforming technology. Among them, massive MIMO and beamforming are closely related. 1, millimeter wave There are generally two ways to increase the transmission rate of wireless transmission, one

2.4G band, not susceptible to interference, there is better data throughput performance. However, the 5G signal is more easily absorbed by the wall, and the transmission distance is less than 802.11b/G. 802.11n Standard This standard is a change worthy of writing. It can be spread simultaneously in the 2.4/5ghz band, the maximum transfer rate of a single channel is increased to 72.2mbit/s, and 20mhz/40mhz Two bandwidth options are provided, and MIMO

said the situation is based on the basic signal good, There is no same frequency conflict (the wireless environment is relatively clean) in the case of the typical speed, this value basically you hold your computer near the router in the case of the same frequency interference is not too large to click on the network properties can be seen, very intuitive.To put it simply, the simplest way to differentiate a NIC is to differentiate it by the maximum negotiation speed. Simply say that my wireles

If you spend some time in your local computer shopping district, you must have seen many of the pre-n and Draft-n wireless products that have been hastily launched. Before you rush out of your wallet to buy these new products, it is recommended that you take a few minutes and have a good look at what you are buying. Mimo One of the great advantages of 802.11n is MIMO.
