tivo antenna

TiVo people use the Java SDK to write applications that run on the TiVo (actually the code that runs on the server and visualization on the user's TV), and emulators that enable you to run and debug applications on your computer. Here's how to simply set up NetBeans to run/debug the TiVo application. These instructions are for the current NetBeans 4.1 developmen

In the Last Post, "LTE Physical Transmission Resources (3)-time-frequency resources," the final mention of Pcfich and other downstream physical channels, this blog post originally wanted to write Pcfich channel, but in preparation for writing Pcfich, found the need to use the antenna port related content, and these content is not yet written. So this paper first write the antenna port and downlink reference

Mobile phone antennas can be divided into PIFA antennas and Single Pole antennas. As debugging becomes more difficult, a new IFA antenna is added. PIFA AntennaPIFA antenna has the same requirements on antenna height and area. Generally, the dual-band height must be above 5mm. The proposed height of PIFA antenna must b

In general, our common antenna tests in engineering practice are divided into the following types: Near-Field Test In the near-field antenna test, the distance from the test probe to the plane of the tested antenna port is about 3 λ 5 λ. In this case, the antenna test is near-field test.The near-field

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

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 rapid development of modern Wireless communication technology, Wireless Local Area network (WLAN) is widely used. WLAN uses wireless communication technology to transmit data, voice and video signals in the air, so that users can exchange information anytime, anywhere. Worldwide Interoperability for MicrowaveAccess (WiMAX) is a new broadband wireless access technology that provides high-speed internet-oriented connections, and the data transmission distance is up to 50 km. Currently, WL

Recently saw a classmate in order to enhance the mobile phone GPS signal, the antenna DIY to the outside, pulled a very long antenna, their own in the suspicion that this is in line with the principle of antenna design, can really make the signal enhancement? So find the following article to learn.1. RFID Fundamentals RFID (radio frequency identification) is a

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

The antenna pattern is also called the Radiation Direction map (radiation pattern), the far-field direction map (Far-field pattern). The antenna gain is not obtained from the pattern above, and the directional coefficients are obtained from the direction graph. Antenna gain = directional coefficient * antenna efficienc

The most striking reason so they got the job, is their discovery of a new, highly noise resistant,

1. Is the effect of placing an external antenna in the trunk of the car station worse than that in the middle of the roof?A: There are four main indicators of the vehicle's antenna: maximum withstand power, center frequency, bandwidth, and standing wave ratio.The first indicator is generally not taken into consideration, because generally, the maximum withstand power of the external

When you are using a wireless network, you are sure to experience wireless network signal quality problems. To solve these problems, in addition to reducing the shielding, reduce the interference of the same band equipment, the most effective way is to replace the high gain antenna, with the antenna to enhance the transmission effect of wireless network, coverage. However, the purchase of wireless gain

CST dipole antenna simulation, half-wave dipole antenna One. In this paper, a 2013-version of a dipole antenna with a CST simulation frequency of 1GHz is used. The simulation steps are 1. Select an antenna engineering template for CST 2. Set the default units 3. Materials for setting the background (air chamber, etc.)

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 MIMO Modelin this sectio

13.56 MHzSmall-sized Magnetic AntennaThe launch is catching up with the NFC heat wave. I don't understand why there are two standards in China: 2.4g and 13.56mhz. the backend protocols are easy to unify. Isn't it because of the differences in antennas? 13.56mhz is indeed a headache, and the traditional design volume is unacceptable: ApproachingBusiness card sizeAnd also consider pastingMAGNETIC FILM. Prevents the reader from sendingSignal received metal reflection from the mobile phone

Wireless client and wireless AP in a different building, far away, in order to receive the signal, the use of the plate gain antenna, but still no signal. In general, adding an external gain antenna will increase the distance of the network connection, the network terminal has no signal, the directional fault may be directional antenna. You can adjust the

In wireless networking, we need Wireless antennas to help increase the coverage area. Especially in office buildings, we often see long, mushroom-like wireless antennas, which are used to enhance wireless signals. For wireless antenna products, let's take a look at the following introduction. For many wireless users, the deployment of every wireless lan wlan is not a simple task. The home network may be a good solution. For some enterprise networks, d
