The C-band and Ku band of the electromagnetic spectrum have been around for a long time. Spot beam systems are by their nature limited in coverage. Ku-band uses frequencies in the 12 to 18 GHz range, while Ka-band uses frequencies in the 26.5 to 40 GHz range. Compared to this, the use of frequencies in the Ka-band has only recently started gathering steam. The frequency band 12.5 GHz to 18 GHz is referred as Ku Band. It supports antennas with smaller sizes compare to Ku band. This band is mainly used for fixed as well as broadcast satellite communication services. Similarly, the KA-Sat launched in 2010 serves only Europe, the Mediterranean basin, and small regions in the Middle East. Considering the higher bandwidth requirements of today, one can even say that it is a necessity. The "u" comes from a German term referring to "under" whereas the "a" in Ka- Band refers to "above" or the top part of K-Band. The Ku band frequency range is 11.7 – 12.2 GHz (or 11700 to 12220 MHz) Notice how these frequencies are higher than the C band frequency range. We'll assume you're ok with this, but you can opt-out if you wish. Since there are a number of satellites currently in orbit which function on the Ku-band, there won’t be a problem finding a backup satellite to maintain a continuous link in case the main satellite develops a fault. Each spot beam generally covers at most a few thousan… Both Ku-band and Ka-band signals suffer from rain fade; however, the fading is larger for Ka-band signals owing to their higher frequencies. Even though the technological shift towards higher frequency signals will continue to push many more applications to communicate in the Ka-band in the future, the Ku-band, like the C-band and the L-band before it, will continue to remain important and reliable options. Let’s find out. Two thirds of all locations see only a single I-5 satellite and are thus covered by only a single Global Service spot beam. It is also used in specific applications such as in communications between space shuttle and the International Space Station (ISS), as well as radar applications. Since wavelength is inversely proportional to frequency, the wavelengths of signals in the Ka-band are much smaller than those of the Ku-band. It is one of the major technologies used today for high-speed satellite Internet. Just click on the icons to download a compatible browser. The Ku-band satellites are often placed as little as two degrees apart from each other in the Earth’s orbit. But here’s a dirty little secret. These Ku-band satellites utilize continental scale wide beams. In short, passengers can access anything available on the internet, in real-time, wherever they fly. What are the main differences between Ka band and Ku band? A solution that might be fine for a twin-turbine that flies a few hundred miles isn’t going to cut it for a heavy-iron business jet that makes frequent flights overseas with the CEO onboard. But which one of them is better suited for the future of satellite communication? This is the most noticeable difference. !Want to remember the correct order of Ku, K and Ka radar bands? These upgrades will allow users to access the Wideband Global SATCOM (WGS) system. This is unlike the conventional system where one large beam is used to serve the entire area of coverage. This makes it possible to reuse frequencies multiple times, making HTS satellites more efficient. The Ka-band satellites are placed further apart from each other, and therefore, the chances of antennas transmitting to non-targeted satellites and interference between signals is much less. “a” from “Unter” (under) and “Above”, respectively. But the real difference lies in a superior customer experience that will delight business-jet passengers, especially those who’ve lived through the frustrations of slow and unreliable in-flight Wi-Fi service. Ku-band utilises approximately 12-18GHz, and; Ka-band services uses the 26.5-40GHz segment of the electromagnetic spectrum. Did you know that your internet browser is out of date?

Not surprisingly “Ka” stands for “Kurz above”. NASA’s Kepler mission utilizes frequencies in this band to down-link scientific data collected by the space telescope. Ku Band VSAT. But, before that, we shall learn more about the HTS systems. This fact, coupled with the frequency-reuse capability of the multiple spot beam technology of the HTS, increases the usable spectrum that is available. This makes them more susceptible to bad weather and other atmospheric disruptions. From a commercial point of view, Ku-band is better for satellite applications that need smaller bandwidth, as the equipment is cheaper than C-band. The middle portion of K-Band is a bit of a mystery. We hope you enjoy this website. There is a lot of chatter in the marketplace right now regarding the pros and cons of Ka- vs. Ku-band. Obviously, none of these are a viable option for ships or intercontinental airplanes, which need to traverse the non-covered oceanic zone. Ku-band satellites, on the other hand, are more in number and have a much wider coverage area in comparison to Ka-band satellites. The Ku band refers to the band of electromagnetic frequencies in the range of 12-18 GHz. With the addition of three more satellites, the first of which will launch in 2019, Jet ConneX will provide even greater bandwidth and additional coverage for the busiest regions of the world. Following frequencies are used in uplink and downlink in Ku band VSAT. Each spot beam covers an area that is only about 1% to 2 % the size of the conventional beam. Summary: Your passengers couldn’t care less. For now, debate continues on the relative merits of Ku-Band and Ka-Band solutions. K band is … This page is not available in English. Some Physicists Believe the Universe is a Hologram, Everything We Know About Pluto’s Red Whale. But which one of them is better suited for the future of satellite communication? We apologize in advance for any inconvenience. Ku-band is under that in the frequency of 12 – 18 GHz. The best option depends largely on the aircraft, its size and mission. The frequencies in the Ka-band are nearly double that of the frequencies in the Ku-band. The frequencies in the Ka-band are nearly double that of the frequencies in the Ku-band. Ku-Band options simply can’t deliver comparable levels of service and performance. Chances are your most important customers are ambivalent at best. Given passenger expectations, most aircraft flying today are probably ready for a connectivity upgrade. The technical details obviously set the Honeywell-Inmarsat Ka-Band solution apart from even the best Ku-Band options. PM WIN-T is procuring Ka- and X-band upgrade kits for existing Ku-band terminals. Hence, smaller-sized antennas can be used for the systems that operate on the Ka-band as compared to the ones used for the Ku-band. 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. 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. Rains drops are known to absorb signals having frequency above 11 GHz. However, that doesn’t mean that it will abolish the Ku-band operations. We have the largest Ku-band VSAT coverage, so you can get the global or regional network coverage your business needs. There are four Inmarsat I-5 GX satellites to cover the entire globe. Krysti joined Honeywell in October 2018 and specializes in all aspects of digital marketing and strategy, including search engine optimization (SEO), search engine marketing (SEM), paid social, display advertising, retargeting, content syndication, audience analysis and developing data-driven content strategies. However, in comparison, there are far fewer satellites that function in the Ka-band of the spectrum, and the ones that do, are often part of a closed network. As such, there are an extensive number of satellites and services which use frequencies in these bands. This band is located directly above the K-band. One major difference is the frequency of each band, which affects the quality of the connection provided. The current Ka-band satellites are incapable of providing coverage to them. We have scheduled maintenance on March 13, from 8.00 AM MST to 8.30 AM MST during which Techpub Module is not available, followed by March 13 from 11:00 PM MST to March 14 03:00 AM MST during which OrderStatus application will be intermittently available. For example, the ViaSat-1 launched in 2011, only provides coverage to North America. Following are the advantages of K Band: It supports high throughput compare to Ku band. Because of the high stakes, many in the industry are comparing the Ku-band and Ka-band technologies. Thus overall performance is better than that of the conventional system. If you need proof, just watch the eyes glaze over when we start to explain wavelengths to a business jet traveler who wants nothing more than in-flight Wi-Fi that is fast, reliable and available anywhere in the world. A smaller dish size and a K u band system's freedom from terrestrial operations simplifies finding a suitable dish site. 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.
