This webinar uses Wireless InSite’s MIMO simulation capability to predict the multipath and channel characteristics for a Massive MIMO system in an urban small cell. Watch the full webinar on our website! #UrbanSmallCells #5g #mimo

National Telecommunications and Information Administration (NTIA) will hold a virtual workshop on Wednesday, November 6, 2024, from 10:30 a.m. to 12 p.m. ET. on lunar propagation models. The workshop will feature a presentation by NTIA’s Institute for Telecommunication Sciences (ITS) and a panel discussion among lunar propagation experts from NTIA, the National Aeronautics and Space Administration (NASA), the Federal Communications Commission and industry. Greg Skidmore from Remcom Inc. will be joining as a panelist to share our expertise on challenges facing lunar propagation and how we can predict channel characteristics in challenging #Artemis missions for #LunaNet

🎃 𝗛𝗮𝗽𝗽𝘆 𝗛𝗮𝗹𝗹𝗼𝘄𝗲𝗲𝗻! I was curious how electric fields between two headphones travel around/through the human head. Does it travel around the head or through the head? I simulated 4 scenarios in Remcom Inc.'s XFdtd 𝗦𝗰𝗲𝗻𝗮𝗿𝗶𝗼 𝗔:  The realistic case I experience when wearing headphones (sort of spooky already #blackmagic) 𝗦𝗰𝗲𝗻𝗮𝗿𝗶𝗼 𝗕: The human is split in half by a perfect electric conductor (PEC) (𝗭𝗼𝗶𝗸𝘀!) 😱 𝗦𝗰𝗲𝗻𝗮𝗿𝗶𝗼 𝗖: A PEC plate surrounding the head (to couple, waves must travel through the body) 𝗦𝗰𝗲𝗻𝗮𝗿𝗶𝗼 𝗗: (the most disturbing) PEC plate splitting the human in half, but freespace surrounds the head 𝗔: 𝗥𝗲𝗮𝗹𝗶𝘀𝘁𝗶𝗰 𝗖𝗮𝘀𝗲 (𝘄𝗮𝘃𝗲𝘀 𝘁𝗵𝗿𝗼𝘂𝗴𝗵 𝗮𝗻𝗱 𝗮𝗿𝗼𝘂𝗻𝗱 𝗵𝗲𝗮𝗱) S11 = -9.123 dB S21 = -57.120 dB 𝗕: 𝗣𝗘𝗖 𝘀𝗽𝗹𝗶𝘁 𝗵𝘂𝗺𝗮𝗻 (𝗽𝘂𝗿𝗲𝗹𝘆 𝗱𝗲𝗰𝗼𝘂𝗽𝗹𝗲𝗱) S11 = -9.09 dB S21 = -inf 𝗖: 𝗣𝗘𝗖 𝗔𝗿𝗼𝘂𝗻𝗱 𝗛𝗲𝗮𝗱 (𝘄𝗮𝘃𝗲𝘀 𝘁𝗵𝗿𝗼𝘂𝗴𝗵 𝗵𝗲𝗮𝗱) S11 = -9.1 dB S21 = -87.358 dB 𝗗: 𝗣𝗘𝗖 𝗔𝗿𝗼𝘂𝗻𝗱 𝗛𝗲𝗮𝗱 (𝘄𝗮𝘃𝗲𝘀 𝗮𝗿𝗼𝘂𝗻𝗱 𝗵𝗲𝗮𝗱) S11 = -9.17 dB S21 = -57.042 dB 𝗖𝗼𝗻𝗰𝗹𝘂𝘀𝗶𝗼𝗻𝘀: Most of the fields travel around the head, although there is a small amount of coupling through the tissue. 𝗠𝗼𝗿𝗲 𝗗𝗲𝘁𝗮𝗶𝗹𝘀: The antennas are curved PIFA antennas designed by my friend Hugh Smith The human is Silicon Type II at 2.44 GHz The eyes are also Silicon Type II. The human model is only 1 material. #Remcom #electromagnetics #antennas #onbody

Wireless InSite supports the simulation of RF interactions with engineered electromagnetic surfaces (EES). This allows modeling of passive metasurfaces designed to optimize wireless communication coverage by manipulating how signals propagate through a scene.

XFdtd's transient EM/circuit co-simulation capability combines a time-domain circuit solver with its full wave electromagnetic solver and uses co-simulation to update complex circuit structures at each timestep in an FDTD simulation. Visit our website for more details!

In this presentation, learn how WaveFarer Radar Simulation Software uses ray-tracing to simulate virtual drive scenarios and predict radar returns as a system moves through an environment with vehicles, roadway structures, pedestrians, and other objects. #radar #raytracing #automotive

In this month's newsletter, Wireless InSite simulates radar altimeter interference for a landing aircraft due to emissions from 5G base stations. Plus, a closer look at #NASA's LunaNet project and Remcom's participation in the effort!

In this example, we look at the measurements of propagation path loss at 910 MHz in Ottawa, Canada 🇨🇦 #wireless #propagation
