我們公司在今年九月滿10週年了，在上週有一場活動在慶祝公司的第10年生日，這是當天的開場影片。

This is the original version and it can't indeed support read back features. We already integrate the Power Detector into the TMYTEK GUI and it support raw data read back function. May I know the series number of the Developer Kit you own? Could you please provide your contact information so that we can assist you better?😄

Warm greetings, In this instance, the 2.5 GHz intermediate frequency (IF) signal serves merely as a carrier frequency. Depending on your baseband equipment, it can be modified to a different frequency. Regarding whether the 2.5 GHz is the same mid-band frequency used by Vi and BSNL for 4G in India, and by T-Mobile for 5G in the USA, the answer is yes. The 2.5 GHz band is commonly used for these purposes in different regions. For the total bandwidth used in this context, it can vary depending on the specific baseband equipment and configuration. Please provide your contact details (e-mail or other) so we can offer further information and assist with your research.👍 Thank you.😀

@@TMYTEK Hi Warm greetings to you too, I am simply a computer science engineering student in India and have keen interest in technology. I don't have any research purpose or project but thanks for offering help and assist. I understand that block of MHz can be different in same n41 band. Right now I can only wonder how extra-ordinary 6G is going to be. From 2G GPRS to 3G H+ to 4G to CA LTE & now to NR. The progress I have experienced in less than 2 decade, I am so greatful for it. Thanks for making our lives better, you are doing good job in research. I hope to be part of that one day too.

Dear friend, thank you for watching this interesting video and raising your relevant question. At the 01:48 mark in the video, the speaker mentions the keyword "measure distance". This "measure distance" actually refers to the sensing part. The video demonstrates an example of a wireless communication system, and to complete wireless transmission, apart from sending and receiving communication data, a sensing step is also needed to obtain the distance information between the transmitter and receiver. Determining the distance between the transmitter and receiver is crucial for evaluating the transmission conditions of the wireless channel. The farther the distance, the more obstacles and attenuation the radio waves will encounter during propagation, resulting in a higher bit error rate (BER). Therefore, accurately measuring the distance between the transmitter and receiver is essential for analyzing and compensating for channel effects. In summary, although the focus of the video is to demonstrate data transmission and BER degradation in a wireless communication system, the "measure distance" step actually corresponds to the sensing distance function, which is an indispensable and important component of a wireless system. I hope this explanation helps you better understand this example. If you have any other questions, feel free to ask.

Hallo, dies ist ein Video, das mit Adobe After Effects erstellt wurde. Sie können relevante Informationen auf der Adobe-Website nachschlagen :)

😊Thank you for your attention and guidance, and for paying close attention to the details. In the video, the MIMO setup is indeed a suitable application for the experiment. However, due to practical constraints in the setup environment, a quick and easy method was chosen for implementation. We can schedule a time to connect and discuss in more depth.😃 👉calendly.com/tmytek-livedemobooking/tmytek-live-demo-reservation-2023

@@TMYTEK This is not the question I asked. Rather, are you able to make a comparison without resorting to highly directional antennas at the end nodes? I would posit that the reference case will be closer to the RIS case if you employ omnidirectional antennas at the end nodes.

😄Thank you for your attention and guidance, I understand your question, and the idea of using omnidirectional antennas is indeed worth considering. In the actual experiment, we chose to use directional antennas due to certain constraints. Nevertheless, your suggestion for comparing the reference case and the RIS case using omnidirectional antennas at the end nodes is valid. You can refer to the video starting from 👉03:00, which showcases another field experiment using omnidirectional antennas at the ends. This approach provides a reference case that is closer to the RIS scenario, allowing for a more comprehensive understanding of the performance under different setups.😃@@JamesRains-u8b

Hi Sir, Thanks for you interested in our product. Regarding to Beamforming, it must have multi channels which own gain controller and phase shifter independently. And, it must be calibrated for exact beam controlling. You can refer to anther video that is the latest BBox One 5G, and you will find the function block of a Beamformer. *th-cam.com/video/QlBB1dQ2s-Y/w-d-xo.html* If you have any questions or require further support, please don't hesitate to reach out to us at *E-mail: sales@tmytek.com* We look forward to hearing from you!🙂

@@TMYTEK Thank you so much. Yes, I underestand; it's very interesting. But, I ask for 2*2 MIMO base station that supports beamforming. For 2*2 MIMO antennas, there is two independent port (port1, port 2), to the best of my knowledge, each port has array of antennas! So, it's 2*2 MIMO base station based on Beamforming? It's worth to mention also, this 2*2 MIMO operates at millimeter wave such as 28 GHz for 5G NR. It's feasible that? what do you think! Do you have any idea about that?

@Bst Anis Dear Bst Anis, We apologize for the delayed response to your comment. We appreciate your interest in our content and * will strive to* respond promptly in the future. Acroding your question, it depends on your beamforming topology, i.e., digital/analog/hybrid beamforming. BBox series only has one RF COM port to connect one data stream to each BBox; it is feasible for hybrid beamforming. As a result, you will need multiple BBoxes for 2x2 MIMO application. For more information, you are very welcome to visit our website: www.tmytek.com/products/beamformers/bbox , and contact us (sales@tmytek.com) for more detail, i.e., datasheet and application note. We look forward to hearing from you and are always here to help you succeed!😄

Glad you liked it😊

Thanks for your suggestion. Actually, it's the best method for radiation pattern test by using RF absorbing material. We had do some test in CATR, the test results were slight affected with or without absorbing material. In general, the antenna type is patch antenna, so the backward radiation is very small. And, the metal of BBOX housing wouldn't impact radiation pattern test. Contact us for a free-spirited discussion? 😃 👉calendly.com/support-tmytek2021/20210916

The 28-GHz coaxial collinear antenna is used in this kit, and it is an omni-directional antenna with vertical polarization.
