MSDSL. Два мегабита по двум проводам

Приветствую всех!

Не так давно я уже рассказывал про ADSL и всё, что с ним связано. Когда-то давно благодаря этой технологии многие впервые смогли выйти в интернеты на высокой скорости, а кто-то до сих пор пользуется таким подключением из-за дешевизны или за неимением альтернатив.

Но ADSL — технология асимметричная: скорости приёма и отдачи отличаются, а модем подключается только к провайдерскому оборудованию (DSLAM). Сегодня же мы поговорим кое о чём куда менее известном среди простых пользователей: о симметричных системах. Узнаем, как выглядит их оборудование, где оно применялось и как заставить его работать. Как водится, будет много интересного.

u-blox ALMA-B2 Bluetooth 6.0 and 802.15.4 module features Nordic nRF54LM20 Edge AI wireless MCU

u-blox has recently announced the ALMA-B2 standalone BLE 6.0 and 802.15.4 module family built around the Nordic Semi nRF54LM20 Cortex-M33 wireless microcontroller with a dedicated NPU for low-latency Edge AI applications. There are four specific product variants in the u-blox ALMA-B2 series: ALMA-B201, ALMA-B206, ALMA-B211, and ALMA-B216, all of which support Bluetooth 6.0 and Bluetooth Channel Sounding for distance measurement. They also support IEEE 802.15.4, including Thread, Zigbee, and Matter, as well as Nordic’s proprietary 2.4 GHz protocol and NFC. The company also mentions that the nRF54LM20B-based ALMA-B211 and ALMA-B216 variants include an Axon NPU that performs machine learning tasks up...

Qualcomm Snapdragon C to power cheaper, entry-level Arm Windows laptops selling for $300 and up

The Qualcomm Snapdragon C (Compute) Arm SoC is designed for entry-level Arm Windows laptops, or “mobile PCs” in marketing speak, with prices starting at $300, which should compete against entry-level laptops using Intel Alder Lake-N or Twin Lake processors. The company didn’t provide many technical details, but we do know the Snapdragon C comes with an NPU for AI acceleration, and said it’s based on Kryo mobile cores rather than the more recent Oryon cores at a media event. Qualcomm still promises all-day battery life, smooth web browsing, video streaming, and productivity for students, families, and small businesses. I’m not...

AMD launches Versal Prime Gen 2 2VM3454, 2VM3254, and 2VM3104 adaptive SoCs in compact 23x23mm packages

AMD has added three new chips to its Versal Prime Series Gen 2 lineup: the Versal 2VM3454, 2VM3254, and 2VM3104. Designed for space-constrained applications like Pro AV, broadcast, and industrial IoT, these new devices deliver up to 100K DMIPS of scalar compute in packages as small as 23 x 23 mm. AMD started shipping the first production units of the Versal Prime Gen2 Series with the 2VM3858 device late last year. The 2VM3558 has since entered full production, while the 2VM3358 is currently sampling. These new devices are designed to provide an optimized footprint and processing subsystem compared to the...

Tuning in FM Radio on a 3D Printer Heatbed

Pooch from Repkord dropped by my studio while he was in St. Louis, and asked a simple question:

Can a 3D printer's heatbed act as an antenna?

A fair question, as many an antenna is embedded in a PCB these days... and the traces on a PCB heatbed like the one used in Prusa's Core One look kinda like an antenna, if you squint the right way.

Really, anything (or anyone) can be an antenna, given enough power.
