In three years or so, the Wi-Fi specification is scheduled to get an upgrade that will turn wireless devices into sensors capable of gathering data about the people and objects bathed in their signals. In this WiFi is following the footsteps of Bluetooth that got location features already some years ago. “When 802.11bf will be →
I have written about running audio signals over CAT 5/6/7 wires normally designed to carry Ethernet traffic. But is is possible to run Ethernet over audio cabling terminated with XLR connectors? Gearspace discussion at topic “Ethernet over XLR – Can I do this ???” had following question: We recently moved into an old recording studio →
FTP is 50 years old article tells: The 16th of April 1971 is not only the date when the Rolling Stone first released Brown Sugar, it is also marked with the publication of RFC 114 marking the birthday of FTP. Back in those days, the Vietnam war is at the forefront of the news, TCP/IP →
An audio multicore cable (often colloquially referred to as a multicore, snake cable or snake) is a thick cable which usually contains 4–64 individual audio cables inside a common, sturdy outer jacket. Audio multicore cables are used to convey many audio signals between two locations, such as in audio recording, sound reinforcement, PA systems and →
I saw today changes made to telecom infrastructure in Helsinki Finland. A huge arm thick telephone cable (800 ot 1000 pair according to installers) that was pulled out of cable pipe with help of excavator. It was being replaced with modern optical cable 192 fibers in it that the installers were pulling in. →
I have have had for many years Mastech MS6811 cable tester. This tester model seems to be still selling typically at 15-30 Euros price range (and sometimes at higher price). Besides Mastech brands it is sold with different brand names for example AXIOMET and Sinometer. The MS6811 is designed to detect the most common wiring →
NOYAFA NF-8209 Network Cable Tester is used to measure cable continuity. It enables the measurement of connection errors in UTP / STP twisted pairs. The device is manufactured by SHENZHEN NOYAFA TECHNOLOGY CO., LTD and sold with several different brand names. NF-8209 Main features： 1. Two scan modes selectable: AC filter & Non AC filter. →
Copper interconnections are easy but have speed limits and traditional fiber-optic cables don’t work well directly with the silicon chips. New hair-thin polymer ribbon was able to transmit data on three channels at a speed of 105 gigabit per second over polymer ribbon 30 centimeters long and 0.4 millimeter wide, with far greater energy-efficiency than →
Fiber maybe for some fastest backbone runs and longest runs properly protected and handled with proper care. But in many applications the main media is copper cable where the media selection is between unshielded (UTP) and shielded (STP) varieties. I have some copper comments on UTP vs STP. STP is nice in locations where good →
Here is maybe simplest power over Ethernet (PoE) powered LED Christmas light. This circuit provides powering of LED light string from IEEE 803.2af compatible standard power supply. On the up there is the IEEE 802.3af PoE power supply that feeds 48V DC power to RJ-45 connector when it detects a PoE needing device connected. I →
