A perfect match 🙌 Our #MFT1500 with the Terrasat Communication, Inc. Intelligent Block UpConverter (#IBUC) is an unique combination that brings exceptional performance in SatCom! 📡 This easily deployable multi-band modular FlyAway satellite terminal #MFT1500 supports your missions and is the terminal of choice! The #MFT1500 terminal distinguishes itself through its operational wind resiliency: It can withstand and operate under very high wind speeds and during severe storms comparable to deployable ground station requirements, nevertheless it is optimized for portability and product longevity. 🌬     #ndsatcom #mft1500 #mft #installingreliability #satellite #communication #satellitecommunications #satcom #defence #government #SKYWAN #makingmissionspossible

Significant challenges still remain when considering the rollout of next-generation antennas within satcom. In this article for Satcom Digital, Helen Weedon, discusses what needs to be done to deliver a coordinated and successful approach to these new technologies. Read more: https://lnkd.in/e2HwRrCM

I would like to provide insight to a few things that are often overlooked when broadcasters talk about new ATSC 3.0 datacasting opportunities. Too often, what is being discussed sounds great but is not practical. My goal isn't to suggest that this is nearly impossible to implement, rather, I would like to point out the real-world scenarios of these discussions. While this chart shows 54-890 MHz, in the USA, there are a total of 35 broadcast channels. Each channel is 6 MHz for a total of 210 MHz of spectrum. 5 of these channels are VHF-Lo and 7 of these channels are VHF-Hi. These channels are unusable for mobile operations because the antenna size required for cell phones is too large. In a best-case scenario, the antenna size required for channel 13 would be just over 1' long and for channel 2, just over 4' long. UHF is better, but there's only 22 of those channels available. The antenna size required for channel 36 is just over 6" and just under 6" for channel 14. You might be saying to yourself, "OK, so VHF in 3.0 does not work for mobile but UHF looks promising". The original post below makes three very aggressive assumptions- 1) It was assumed that every channel is available for use. In any populated area, they are not, as most populated areas share these same frequencies with other adjacent markets. In my home market of Chicago only 9 of the 22 UHF channels are being used for full power stations. The adjacent markets of Milwaukee, Rockford, and South Bend utilize the remaining 13 UHF channels. 2) This post also assumes 9 Mbps for every MHz, which is 54 Mbps for a full channel. This calculation is extremely aggressive. Not only would this level of bandwidth completely eliminate the possibility of data to a cell phone or car, but it would also absolutely require an outdoor antenna to be connected to the receiving device. This alone eliminates a majority of the potential use cases that are being pitched. 3) These aggressive assumptions assume that all spectrum is being used for datacasting purposes. As a licensee of a broadcast station, we are required to serve the public. We can make money while fulfilling this obligation, but we are not permitted to eliminate our primary linear service at the expense of potential business opportunities. What does all of this mean in the end? VHF is not practical for mobile datacasting due to the large antennas required. UHF is practical, but there are anywhere from 3-12 full power channels available in a given market. 54 Mbps is not practical for most use cases due to the laboratory conditions required. A more practical number for reliable mobile operation, assuming one linear channel, is 3-10 Mbps. In the end, assuming 10 Mbps per channel in a market that has 12 channels, assuming all are participating in a shared datacasting agreement, this would yield 120 Mbps- Far less than the 1.9 Gbps positioned. Most of us have more than 120 Mbps in our homes today. Comments welcome.

One of the limitations of legacy radios is monitoring only one frequency at a time. In a situation where interference occurs on one or more frequencies in a row, it can take minutes to establish a connection, which is a critical delay in many scenarios.   KNL’s CNHF radios tackle this issue by listening to 4000 call channels simultaneously and when interference is detected, the radios switch to an interference-free channel in less than 500 milliseconds!     Fast link establishment means that a communication channel can be established anytime, anywhere, even in the case of severe interference on multiple frequencies.   Learn more: https://lnkd.in/dxderQHx   #KNL #GetConnected #CNHF #Manpack #TacticalCommunications
