Now, wireless designers are faced with the arduous task of designing world-class products. Many wireless technical standards define the technical indicators of power, but ignore the specific steps of Power Measurement. Therefore, designers often encounter Errors During measurement. Because the ofdm rf waveforms used in IEEE 802.16 are complex, more errors occur when measuring mobile WiMAX signals. This article describes important information about

The antennas are clear to everyone. We used to build antennas on the roof to receive TV signals. However, with the development of the times, we have seldom seen strange TV antennas, instead of Various wireless antennas. What is a wireless antenna? Of course it is an antenna related to wireless signals. What is a wireless antenna? Before answering this question, l

With the popularization of 3G technology and the development of wireless standards and technologies such as LTE, NFC, Bluetooth 4.0, cmms B, and MIMO, mobile Terminals need to integrate multi-band main antennas (supporting 2g, 3G, LTE and other multi-standard), as well as GPS, BT, WiFi, NFC, wireless charging and other antennas. As a result, terminal antenna engineers are facing huge challenges: Antenna siz

Each wireless technology has its own advantages and disadvantages. Various kinds of publicity are also emerging. Therefore, this article only compares the wireless WINMAX technology with other wireless technologies, so this article mainly compares with the 3G wireless technology. WiMAX to 3G 3G is an ITU specification that supports high-speed wireless communication. This global wireless connection is compatible with GSM, TDMA, and CDMA. The next gener

The antenna theory of the experts is simple: http://www.52rd.com/bbs/Detail_RD.BBS_187060_42_1_3.html The problem must be analyzed in essence. The above two images can be used for analysis. Antenna evolution can be analyzed by transmission lines. The transmission lines are represented by the same axis. The same axis is divided into core, insulation layer, and shielding network. When the complete Coa

With the development of global 4G networks in full swing in recent years, how to simplify the deployment of remote adjustment antennas and improve their reliability has become a new concern of operators for the antenna feed system. Due to its inherent requirements for on-site access, low operation and maintenance efficiency, and affected antenna radiation performance, the method of mechanical tilting optimi

First of all, a misunderstanding is: the more the antenna coverage, the more the antenna signal stronger MIMO (Multiple-entry) is the technology of multiple antennas is from the 802.11N protocol only after the 802.11a,b,g have not. That is to say, the first generation of routers (802.11n ago) will never have more than one antenna. And you bought a new 3-day line

Reference: 1. wikipedia The dipole antenna is the simplest and most widely used class of antenna. It consists of identical conductive elements such as metal wires or rods, which is usually bilaterally symmetrical. Each side of the feedline to the transmitter or receiver was connected to one of the conductors. Dipoles is resonant antennas, meaning that the elements serve as resonators, with standing waves

Smart antenna is a kind of bidirectional antenna installed in the base station, which obtains directivity through a set of fixed antenna units with programmable electronic phase relation, and simultaneously obtains the directional characteristic of each link between the base station and the mobile station. The principle of the smart

In the previous article, we introduced what is a wireless antenna and the two basic parameters of the antenna. Next we will introduce in detail what are the outdoor wireless antennas. We have already introduced indoor wireless antennas. We will not repeat them here. Outdoor wireless antenna 1. Omnidirectional Antenna A

WiMAX is a new technology that has been heating up since 2006 and is able to provide "last mile" broadband connectivity in a region wider than wifi, this allows enterprise customers to enjoy class T1 services and the access capability of resident users equivalent to cable x/

An antenna (antenna) is a transducer that transforms a traveling wave propagating on a transmission line into an electromagnetic wave propagating in a unbounded medium (usually a free space), or in reverse. A component used in radio equipment to transmit or receive electromagnetic waves. Radio communications, radio, television, radar, navigation, electronic confrontation, remote sensing, radio astronomy and

0 In the design of various communication devices and terminal electronic products, more and more embedded systems are used to make the products have more powerful functions, as are WiMAX wireless communication devices. Therefore, when designing and developing security technologies in modern network and communication technologies, they must be integrated with embedded technologies. In this paper, a solution of WiMA
