We terminate fiber optic cable two ways – with connectors that can mate two fibers to create a temporary joint and/or connect the fiber to a piece of network gear or with splices which create a permanent joint between the two fibers. According to Which field-termination method best fits your fiber-optic LAN? article over the →

Or perhaps it’s the other way around. The internet continues to create new business and social opportunities that massively scale and widely interconnect. The increasing depth and volume of personal and corporate data make it a more rewarding target for cyber crooks and →
http://charleshughsmith.blogspot.fi/2017/09/are-facebook-and-google-new-colonial.html?m=1 To qualify as colonial powers, Facebook and Google must effectively limit the choices and power of users, and punish or coerce those who question or resist their power. The phrase that captures this broad narrative is: When an online service is free, you’re not the customer. You’re the product. In other words, if you’re not →
http://www.iflscience.com/technology/scientists-have-managed-to-store-light-as-sound-for-the-first-time/ A team of researchers from the University of Sydney has managed to convert the digital information carried by light waves into sound waves inside a microchip. As reported in Nature Communications, the researchers were able to build a chip that slows down light by turning it into sound waves. “The information in our chip in acoustic →
Fifer optics power meter is an important tool for debugging fiber optics networks. I have earlier tested a cheap commercial fiber optic power meter a at Fiber optics power meter posting. Hardware hackers ares famous for building their own test equipment. The basic operation of optical power meter is quite simple: take a suitable detector, →

Cisco predicts that by 2021, a 5G connection will generate 4.7 times more traffic than the average 4G connection. 5G will be a quantum leap from today’s LTE-Advanced networks. →

Such characteristics are bandwidth, delay (including jitter), packet loss, packet corruption and reordering. Linux has the tc queue discipline ‘netem’ for quite some time now. Netem is capable of emulating all →

Ericsson, Qualcomm, and Verizon claim to be the first to have achieved 1 Gbps using commercial silicon and commercial infrastructure. →
I have created a new category for 5G telecommunications technology topics. New postings related to 5G technologies will be posted under this category. I have also tried to tag older postings related to 5G to this 5G category. 5th generation mobile networks or 5th generation wireless systems, abbreviated 5G, are the proposed next telecommunications standards →
