Direct-to-cell technology uses LEO satellites as spaceborne cell towers. It delivers LTE services to existing smartphones without hardware changes, bridging global coverage gaps. What Attendees will Learn How DTC works as a spaceborne cell tower โ LEO satellites carry LTE eNodeB payloads in regenerative mode. How they serve unmodified phones using quasi-earth-fixed multi-beam antennas. How the satellite compensates for Doppler shift and time delay on thenetwork side. Why Doppler shift and round-trip time are critical challenges โ A LEO satelliteโs high velocity causes carrier frequency offsets in OFDMA systems. Pre-compensation at a reference point helps, but cell-edge users still face residual Doppler. How spectrum sharing and regulation shape DTC deployment โ DTC has no dedicated spectrum allocation. It relies on spectrum sharing between terrestrial and satellite operators or re-farmed MSS bands. How national regulations like the FCC SCS framework govern access. Where DTC fits in the evolution toward 5G NTN and 6G โ DTC is an interim technology offering fast time-to-market satellite services. It bridges the gap until 3GPP NR-NTN matures. How NR-NTN will bring purpose-built NTN features and international spectrum frameworks. Download this free whitepaper now!

The website, which compares human beings to extraterrestrials, touts arrest numbers from the Trump administrationโs sweeping immigration crackdown. But some of its details are really out there.
A group of lawmakers and a former Pentagon whistleblower are spearheading a new drive for the government's full disclosure about extraterrestrials.
Somewhere, a guy wearing a tinfoil hat is having a really tough night. Anyone who rushed to Aliens.gov on Thursday expecting UFO disclosure was in for a rude awakening. Because the website has nothing to do with extraterrestrials, but rather, illegal immigrants. The website โ which looks like something a guy named Randy would show ...
This sponsored article is brought to you by Master Bond. Outgassing is the release of volatile substances from a cured adhesive over time. These released materials, which may include residual solvents, unreacted monomers, or other chemical species, can deposit on nearby surfaces, causing contamination that interferes with sensitive components. What Is Outgassing and How Is It Measured? The industry standard for measuring outgassing is ASTM E595, developed by NASA. This test exposes a cured sample to 125 ยฐC at high vacuum (10โปโต to 10โปโถ torr) for 24 hours, measuring Total Mass Loss (TML) and Collected Volatile Condensable Materials (CVCM). To meet NASA low outgassing requirements, materials must exhibit less than 1 percent TML and less than 0.1 percent CVCM. Optical assemblies need contamination-free bonding and prevention of fogging the optics to maintain clarity. High-vacuum scientific equipment, semiconductor manufacturing tools, and aerospace electronics also demand low outgassing materials. Key Applications Low outgassing adhesives are essential wherever contamination could compromise performance and this is particularly relevant for space and satellite systems. Optical assemblies, including cameras, telescopes, and laser systems, need contamination-free bonding and prevention of fogging the optics to maintain clarity. High-vacuum scientific equipment, semiconductor manufacturing tools, and aerospace electronics also demand low outgassing materials. Even terrestrial optical devices benefit from reduced outgassing to ensure long-term reliability. EP30-2 is a versatile system can be used in a variety of applications in aerospace, electronic, optical and specialty OEM industries, especially when optical clarity and low outgassing are important criteria.Master Bond Ensuring Low Outgassing Performance Through Proper Handling Achieving specified outgassing performance requires attention to storage, mixing, and curing. For two-part systems, use the correct mix ratio and mix thoroughly to ensure complete reaction. Follow recommended cure schedules โ adding heat, even at modest temperatures of 150-200 ยฐF, significantly improves cross-linking and reduces outgassing. For UV-curable adhesives, ensure complete cure by using the correct lamp wavelength (typically 365 nm), adequate intensity, and proper exposure time with no shadowed areas. Troubleshooting Outgassing Issues If contamination appears on optical surfaces or outgassing test results are higher than expected, an incomplete cure might be one of the root causes. The first step is to verify that the adhesive has fully hardened to its specified Shore hardness. The next step is to consider adding or extending heat cure to improve cross-linking. Master Bond Product Recommendations Master Bond offers a range of adhesives meeting NASA low outgassing requirements. EP30-2 and EP21TCHT-1 are some examples of two-part epoxy systems that have been successfully deployed in demanding vacuum applications, including ultra-high vacuum environments. For applications requiring UV cure, Master Bond provides specialty UV formulations such as UV16 meeting ASTM E595, as well as dual-cure systems (UV plus heat) such as UV22DC80-10F for assemblies where shadows prevent complete UV exposure. These dual-cure products initiate with UV light and complete curing with heat as low as 180 ยฐF (80 ยฐC).
The Pentagon's budget is so vast that a soldier believes the extraterrestrial machine shooting lasers at them might be taxpayerโfunded.
A comprehensive review of how spectrum congestion, dynamic sharing, and cognitive radio systems are reshaping RF coexistence testing for military and commercial applications. What Attendees will Learn Why spectrum congestion threatens wireless reliability โ Explore how over 30 billion connected devices, more than 4,000 allocation changes worldwide, and the expansion from 11 to over 80 cellular bands are intensifying contention for finite RF spectrum resources. How real-world coexistence failures affect safety-critical systems โ Understand the interference risks between 5G C band transmitters and aircraft radar altimeters, and between terrestrial L band networks and GPS receivers that were not designed for adjacent high-power signals. Why tiered spectrum sharing frameworks are essential โ Examine how CBRS uses a cloud-based Spectrum Access System (SAS) and environmental sensing to dynamically protect incumbent Navy radar while enabling commercial cellular services across three priority tiers. What coexistence test architectures look like in practice โ Learn how controlled environment testing with anechoic chambers, over-the-air signal generation, and standards such as ANSI C63.27 enable repeatable evaluation of RF device performance under real-world interference conditions.
