K u band satellites are also used for backhauls and particularly for satellite from remote locations back to a television network's studio for editing and broadcasting. The band is split by the International Telecommunication Union ITU into multiple segments that vary by geographical region. NBC was the first television network to uplink a majority of its affiliate feeds via K u band in Some frequencies in this radio band are employed in radar guns used by law enforcement to detect vehicles speeding, especially in Europe.

There are more than 22 FSS K u band satellites orbiting over North America, each carrying 12 to 48 transponders20 to watts per transponder, and requiring a 0.

The Segments in those regions are represented by ITU Region 1 and they are, the In Europe K u band is used from Australia is part of ITU Region 3 and the Australian regulatory environment provides a class license that covers downlinking from This statement has made many people unsure about using K u -band 11 — 18 GHz in Indonesia.

Using frequencies higher than 10 GHz in a heavy rain area usually gives poor results. This problem can be solved by using an appropriate link budget when designing the wireless communication link. Higher power can overcome the loss to rain fade.

Measurements of rain attenuation in Indonesia have been done for satellite communication links in Padang, Cibinong, Surabaya and Bandung. ITU-R P. This model can create a Use of the K u -band for satellite communications in tropical regions like Indonesia is becoming more frequent. Several satellites above Indonesia have K u -band transpondersand even K a band transponders. Other ITU allocations have been made within the K u band to the fixed service microwave towersradio astronomy service, space research service, mobile service, mobile satellite service, radiolocation service radaramateur radio serviceand radionavigation.

However, not all of these services are actually operating in this band and others are only minor users. Compared with C-bandK u band is not similarly restricted in power to avoid interference with terrestrial microwave systems, and the power of its uplinks and downlinks can be increased.

This higher power also translates into smaller receiving dishes and points out a generalization between a satellite's transmission and a dish's size. As the power increases, the size of an antenna's dish will decrease. A major attraction of the band over lower frequency microwave bands is that the shorter wavelengths allow sufficient angular resolution to separate the signals of different communication satellites to be achieved with smaller terrestrial parabolic antennas.

From the Rayleigh criterionthe diameter of a parabolic dish required to create a radiation pattern with a given angular beamwidth gain is proportional to the wavelengthand thus inversely proportional to the frequency. Note the inverse linear correlation between dish size and frequency. As power levels on both C and K u band satellites have increased over the years, dish beam-width has become much more critical than gain.The Ku-band of the electromagnetic spectrum has been in use for quite sometime, while the capability of the Ka-band has only recently begun to be exploited.

But which one of them is better suited for the future of satellite communication? Let's find out. As more of the world migrates towards using wireless technology each day, optimal, high-speed, and reliable wireless connectivity has become the need of the hour. Would you like to write for us?

Well, we're looking for good writers who want to spread the word. Get in touch with us and we'll talk HTS technology boasts an unprecedented bandwidth capability, and is widely viewed as the future of satellite communications. In recent years owing to the explosion in Internet based applications, the demands for higher satellite capacity has skyrocketed.

The capacity of the lower Ku-band of the spectrum is falling short, and investments are now being made in the use of the Ka-band. These bands are not interchangeable, and each has its own advantages and disadvantages, which makes it suitable for one set of applications and unsuitable for another.

In the following sections, we shall examine the differences between Ka-band and Ku-band. But, before that, we shall learn more about the HTS systems. In the High Throughput Satellites system, the coverage area is divided into small regions known as spots. Each spot is then served by a spot beam.

This is unlike the conventional system where one large beam is used to serve the entire area of coverage. This allows these beams to provide high signal strength as well as gain. Thus overall performance is better than that of the conventional system. Newer advanced technology also allows more accurate antennas to be built and thus the spots can be made smaller. This makes it possible to reuse frequencies multiple times, making HTS satellites more efficient.

The Ku band refers to the band of electromagnetic frequencies in the range of GHz. It is located directly below the K-band. This band is mainly used for fixed as well as broadcast satellite communication services. It is also used in specific applications such as in communications between space shuttle and the International Space Station ISSas well as radar applications.

Whether traveling for business or pleasure, your passengers want — no, expect — the same user experience at 35, feet that they enjoy on the ground, in their home or office. While other satellite communications options like the L-Band and Swiftbroadband are still widely used in general aviation, the choice for high-speed in-flight Wi-Fi capabilities boils down to either an older, more established Ku-Band system or the newer, faster Ka-Band solution.

The choice is best left up to the technical experts and frankly most owners and operators rely happily on their flight operations department to make the call.

The best option depends largely on the aircraft, its size and mission. Given passenger expectations, most aircraft flying today are probably ready for a connectivity upgrade.

Even aircraft that rolled off the assembly line early in this decade are often equipped with only air-to-ground systems or low-speed voice and data capabilities. The best equipped operate on the Ku-band and probably connect with top speeds in the mbps range — too slow to satisfy most discriminating business aviation passengers.

Performance of Ku-Band systems has improved in recent years with typical speeds now around 18 mbps. Each satellite in the Inmarsat 5 constellation operates 89 highly efficient Ka-Band spot beams, giving the network reliable global coverage, except at the poles.

With the addition of three more satellites, the first of which will launch inJet ConneX will provide even greater bandwidth and additional coverage for the busiest regions of the world.

Displaying 1 to 17 of 17 products.The Ku band Kurtz-under band is primarily used for satellite communications, particularly for editing and broadcasting satellite television.

This band is split into multiple segments broken down into geographical regions, as the ITU International Telecommunication Union determines. The Ku band is a portion of the electromagnetic spectrum in the microwave range of frequencies ranging from The first commercial television network to extensively utilize the Ku Band for most of its affiliate feeds was NBC, back in Each requires a 0.

The These direct broadcast satellites typically carry 16 to 32 transponders. Each provides 27 MHz in bandwidth and consumes to watts each, accommodating receiver antennas down to mm 18 inches.

This problem can be combated, however, by deploying an appropriate link budget strategy when designing the satellite network and allocating a higher power consumption to overcome rain fade loss. In terms of end-viewer TV reception, it takes heavy rainfalls in excess of mm per hour to have a noticeable effect. Also, the Ku band satellites typically require considerably more power to transmit than the C band satellites.

The Ku band downlink uses frequencies between Services that can be found on the Ku-band include educational networks, business networks, sports backhauls, tele-conferences, mobile news truck feeds, international programming, various SCPC Single Channel Per Carrier transmissions of analog audio, as well as FM audio services. As for the coax cable recommended, RG-6 is optimal for low loss in the frequency range, which is what Ku-band LNB processes.

However, if RG is the only viable option, it will work in a pinch. A 4 section dish is more optimal than an 8 section dish. The fewer the sections, the more accurate the parabola shape is and the more difficult it is for the dish to become warped the smaller the number of seams the better.

As far as dish mounts go, the H2H Horizon-to-Horizon dish mount is more desirable than a polar mount. This is due to the fact that the Ku-band demands that the dish antenna system is well targeted and able to closely follow the orbital arc, which the H2H mount does quite admirably when compared to a polar mount. Also, bear in mind that the user will be adjusting both the azimuth and elevation, which can be a bit tricky occasionally. Some tape and string is all that is required to do a quick warpage check.

Make sure that both strings are tight. If the strings come together anywhere but the direct center, the dish has sustained warp damage and needs to be bent back into proper parabola shape for optimal performance.

If they connect in the center of the dish, it is likely that the dish is not warped. Therefore, use either the tri-supports or quad supports as they will greatly assist in keeping the Ku-band feed horn highly stable, even in high winds. When the button hook feed moves in the wind, Ku-band reception can easily drop out. By putting guy wires on the button hook feed, the user will create the much needed support in the event that the user is unable to obtain a tri support or quad support.
