GSM repeater & signal booster extends 2G/3G/4G cellular coverage in your house or building

If your WiFi router range does not cover some of your rooms what do you do? You install a WiFi repeater or some of the more recent WiFi mesh networking solutions. What I did not know is that you can do something similar for cellular connectivity if you don’t quite get a reliable signal from your telco’s base station. Specifically, I’ve just come across a 900 MHz GSM repeater & signal booster that claims to be able to extend the 2G, 3G, and 4G cellular signal in a 100 to 300 m2 area, and sold for $59 on Banggood. Here are the specifications listed for the GSM repeater: Operating Frequency Band – GSM Uplink: 890-915Mhz Downlink: 935-960Mhz Gain: 70dbm Outdoor Directional Antenna Gain – 8dB Compatible with 2G / 3G / 4G cell phone signal Power Supply – 12V DC via 110-240V DC adapter Dimensions – 135 x 105 x […]

Arm CPU Roadmap to 2022 – Matterhorn and 64-bit only Makalu CPU Cores

Arm Roadmap Peak Performance Matterhorn & Makalu

The Arm DevSummit 2020, previously known as Arm TechCon, is taking place virtually this week until Friday 9th, and besides some expected discussions about NVIDIA’s purchase of Arm, there have been some technical announcements, notably a high-performance CPU roadmap for the next two years, which will see Matterhorn (Cortex-A79?) in 2021, and Makalu (Cortex-A80?), the first 64-bit only Arm processor, in 2022. The company did not provide many details about the new cores, but they expected a peak performance uplift of up to 30% from the Cortex-A78 to the future Makalu generations. It should be noted that while performance keeps improving, the curve has flattened a bit. But the main announcement is that starting from 2022, all high-end Arm CPU cores (i.e. the “big” cores) will be 64-bit. So far, most Cortex-A cores supported both 32-bit (Aarch32) and 64-bit (Aarch64) architecture, and as we noted four years ago, the latter […]
