Summary:
|
In order to achieve sustainable growth under the constraints of the environment and resources, it is necessary to radically change conventional waste and recycling measures. Conventional waste countermeasures have mainly been recycling (reuse as a raw material), but in addition to this, reduction (control of waste generation) and reuse are also important.
For example, twisted pair cables, such as 4-pairs of unshielded twisted pair (UTP) or shielded twisted pair (STP) cables, are used in various local area networks (LANs), a large amount of copper resources are still required to provide Internet services around the world. If fewer number of pairs can achieve the same communication performance as 4-pair type, the resource saving in the network can be realized.
This Supplement provides various examples of resource saving in building systems, factories, plants and home applications due to the progress of ICT technologies, one of which is an example of resource saving in the home network by using the Single-pair Ethernet (SPE) technology.
