Why should you care, well they are both a type of electromagnetic interference that can cause poor performance issues as well as a partial or complete loss of your broadband service. They are invisible to the naked eye and as a general rule cannot be heard or felt without special equipment.
REIN- Repetitive Electrical Impulse Noise / Random Electrical Impulse Noise
SHINE- Single High Impulse Noise Event (Single High-level Impulse Noise Event)
Essentially both rein and shine are a type of powerful radio wave that exists in the same frequency range as that used by your broadband service. Generally, both rein & shine are the by-products of faulty or poorly designed electrical equipment, electrical equipment that either generates or uses a lot of power. In the case of rein the equipment will often be faulty & cause a fairly consistent electromagnetic output whilst it is on. With shine the electromagnetic interference is generally associated with the exact time the equipment is switched on or off.
Leisure appliances (TVs, Skybox, satellite receiver, digital receiver)
Other appliances (Laptops, Routers, Access points, Switches, Hubs, Repeaters, transmitters)
3 Phase power usage
Railway lines
Electric fences
Electric gates
Electric motors
Christmas tree lights / some external lighting including
Mobile / Temporary lighting
Security systems
Security lighting
High power switching equipment
Digital Communication Transmitters
Data cables in close parallel proximity to power cables
Credit card payment machines, and electronic cash registers.
Dispersing machines
Major structural works – road/building/infrastructure
Emergency services / military communications
Cars, motorcycles etc
The list above demonstrates the nature of some of the types of equipment that can cause rein or shine. Whilst it is not an exhaustive list it can be seen that many of the potential sources would reside within a domestic or business customer's property. As such you may be required to do some diagnostic testing to identify the source of interference or try to prove that any interference does not come from within your property.
It is worth noting that even if the source of the interference is external to your property, it still may not be the responsibility of your service provider to identify & resolve it. One example would be if the origin of the interference was faulty equipment in a nearby property.
Your service provider may be able to offer some assistance with the help of Openreach or an independent service such as Burytec. If you have done as much as you can to try to track down the interference & you feel that you are making very little progress you could try an analog radio tuner set to AM 612 KHz. As you move closer to the source the sound on the radio should become significantly louder.
Many cases of interference can be tracked down by a process of elimination and using monitoring techniques to pinpoint specific times when service failure coincides with the active state of a particular item of electrical equipment.
Several network service monitoring programs are available that can record useful uptime information on a graph, this makes it very easy to identify any patterns.
