    what is ka band technology

    L/Ku/Ka-band satellites – what does it all mean?

    t. e. The Ka band (pronounced as either "kay-ay band" or "ka band") is a portion of the microwave part of the electromagnetic spectrum defined as frequencies in the range –40 gigahertz (GHz), i.e. wavelengths from slightly over one centimeter down to funslovestory.comncy range: –40 GHz. Ka-Band Represents the Future of Space Communications The SCaN Testbed, operating aboard the International Space Station, features two S-band and one Ka-band software defined radios, which will .

    Kacific1 is a next-generation geostationary satellite operating in the Ka-band frequency spectrum. The satellite, which launched in Decemberstreams low-cost, high-speed, reliable, and stable broadband via 56 powerful spot beams.

    Wide reaching coverage extends over 25 countries in Asia Pacific with populations spread across their many islands, mountainous and rural regions. Utilising advanced ground segment technologies, Kacific1 delivers fast internet speeds with a robust quality of service on a small user terminals at a jaw dropping price per month.

    Designed and built by Boeing, the Kacific1 payload is supported by the reliable MP platform. Kacific1 launched atop a two-stage SpaceX Falcon9 rocket into geostationary orbit. By launching other follow-on satellites into different orbital positions, Kacific will be able to provide additional capacity in the Kacific1 coverage areas requiring more, as well as increase the total coverage how to make money by google adwords. Kacific1 is a High Throughput Satellite HTS because it reuses the same spectrum frequencies multiple times in the 56 spot beams.

    This stands in contrast to traditional FSS satellites with wide area beams that can use the spectrum only once. What is ka band technology a sense, an HTS is similar to a mobile cellular system that reuses frequencies between cells.

    Consequently, the total HTS throughput is much higher than an FSS satellite resulting in greater spectral efficiency and therefore lower cost per bandwidth. Modern technologies such as adaptive coding and modulation ACMsignal pre-distortion and uplink power control are used to increase the throughput and overall availability, and, ultimately, improve the quality of service and user experience.

    Kacific1 uses Ka-band technology and spectrum. Because the satellite antennas concentrate the spot beams for frequency reuse, the resulting beams are also high power — resulting in availabilities between Such availabilities are entirely suitable for internet services and in many places exceed the availability of terrestrial networks or even mobile networks.

    Kacific1 is a geostationary satellite, orbiting at 35,km above the equator. Satellites placed in the geostationary orbit offer a very stable and consistent service and user experience. The signal of a geostationary satellite always comes from the same location in the sky and therefore only requires a simple antenna, with no moving parts for reception and transmission. The signal acquisition does not require any complicated terminal handover from one satellite to another, as is the case with satellite constellations using lower orbits.

    These constellations require tracking of moving satellites by ground terminal, which can lead to service issues such as temporary blockages due to landscape and failures of tracking mechanisms. The handover process from one satellite in the constellation to the next introduces a source of instability that is absent in a geostationary satellite system.

    Geostationary satellite latency is suitable for nearly all regular internet usage, such as video streaming, voice calls over IP, general browsing and even for distribution via 3G or 4G networks. Geostationary satellites have been used for decades and are still the most efficient and cost-effective way to deliver telecommunication signals from space.

    The addition of powerful HTS technologies tremendously enhances the ability of geostationary satellites to deliver high-speed internet.

    Ka-band technology opens up the market to a new range of frequencies that is more cost-effective than other bands providing higher quality, better performance and higher speed services. Focused power HTS Ka-band beams are much more focused, resulting in high powered spot beams lit over specific funslovestory.comted Reading Time: 1 min. Ka is the newest and most common band and and you’ll find it on , , and GHz. It has the smallest antennas (because it uses the highest frequencies). Ka falses are also pretty rare so if your detector alerts to Ka, pay attention. Ka-Band. Kacific1 uses Ka-band technology and spectrum. Because the satellite antennas concentrate the spot beams for frequency reuse, the resulting beams are also high power – resulting in availabilities between % and % (depending on the location of the service and the size of the user antenna). Such availabilities are entirely Estimated Reading Time: 4 mins.

    In the world of satellite broadband Internet , Ka-band technology is expanding its footprint in North America as well as the Middle East, Africa and Asia. At the core of the migration to Ka-band is the additional capacity available on Ka-band satellites versus the existing Ku-band satellites.

    As businesses and governmental agencies continue to rely on media-rich applications, the appetite for more and more bandwidth is increasing. Streaming video, VoIP calls and web browsing are increasingly becoming part of the standard business profile. As a result, additional bandwidth is on the menu.

    And in those regions of the world where terrestrial broadband service is not available or because Ku-band networks are saturated, Ka-band service has become the service of choice. Ka-band offers opportunities in the retail, hospitality, government, communications, telemedicine and distance education markets.

    But the biggest driver of entities seeking additional bandwidth is the high-speed Internet customer seeking speeds required to stream movies and other entertainment and the myriad of data-rich applications in the entertainment marketplace. Ka-Band is a relative newcomer to the field because the spectrum has long suffered from a susceptibility to interference from rain and other weather conditions.

    However, the latest generation of Ka-Band satellites feature technology that helps mitigate the rain-fade problem. Now playing on a more level playing field, Ka-band can now better compete with its Ku-band competitors. Over the next several years, satellites with both bands will be put into orbit, expanding the opportunities for the delivery of satellite Internet broadband services. Because of the high stakes, many in the industry are comparing the Ku-band and Ka-band technologies.

    Experts in the field say the primary difference between the Ka-band and Ku-band has more to do with spot beam size than frequency band. Spot beam systems are by their nature limited in coverage. Each spot beam generally covers at most a few thousand square kilometers. However, some high-throughput satellite HTS systems provide large fields of spot beams that collectively create continental and even global coverage , whereas others offer only a relatively small number of fixed or steerable spots in targeted areas.

    Ku-band spot beams and Ka-band large spots beams are similar in beam width and so are generally comparable in system coverage. Ka-band small spot beams, however, generally cover only about percent of the area covered by a large spot beam and these spacecraft tend to offer less total spot beam coverage. While Ku-band satellite service is available all over the world, Ka-band service is relatively sparse.

    Many Ka-based systems are proprietary or closed networks that require specific modem technology or configurations. In the event of a failure on an HTS spacecraft resulting in loss of service, Ku-band systems usually have an alternate backup system.

    That backup alternative is less likely on a Ka-band system, which would require additional ground terminal hardware and onsite electronics. Because they are less common in the marketplace, Ka-band VSAT hardware tend to be more expensive than their Ku-band competitors with similar capabilities.

    Concerted efforts to market Ka-band have been successful. How much of the perception about Ka-band advantages is real remains to be proven.

    Some would argue the Ka vs. Ku debate echoes the discussion in the s about the then-emerging Ku-band and the legacy C-band systems. Many in the industry predicted the demise of the C-band systems.

    In fact, C-band continues to maintain a presence in industrial, military and maritime applications where atmospheric interference is a major consideration. A general school of thought exists that says all frequency bands in existence have a place in satellite communications, with some bands are preferred over others in specific applications.
