The fusion splicers now available are much easier to operate, and reliable, repeatable, very-low-loss splices are the norm. In addition to providing simply faster speeds, they predict that 5G networks also will need to meet the needs of new use cases, such as the Internet of Things as well as broadcast-like services and lifeline communication in times of natural disaster.

The IS-54 speech coder uses the technique called vector sum excited linear prediction (VSELP) coding. This is a special type of speech coder within a large class known as code-excited linear prediction (CELP) coders. The speech coding rate of 7.95 kb/s achieves a reconstructed speech quality similar to that of the analog AMPS system using frequency modulation. The 7.95-kb/s signal is then passed through a channel coder that loads the bit rate up to 13 kb/s Hearing, the determining factor for high-fidelity transmission: Requirements for ideal high-fidelity transmission systems based on measurements of ... / Bell Telephone System.
