A Single Wire Multiswitch or SWM system is a satellite dish with SWM technology built into it, or a multiswitch with SWM Technology. SWM Dishes are identified as having a single output, and are the only such units to require a power supply. Examples of SWM dishes are the SL3-SWM and SL5-SWM.
A SWM Switch takes all four outputs from a satellite dish, and combines them into a single output, which can be divided up with splitters, if need be. The benefit of this system is only having to run one line to a DVR, which normally requires two lines. It also allows for a distribution with splitters, similar to how cable TV is setup.
Another benefit of SWM comes with the addition of a DECA Adapter that feeds internet into one of the outputs from a SWM system. This enables every receiver to have a network connection through a single coax. With the combination of a SWM technology and DECA, you get a DIRECTV-connected home that features multi-room viewing (MRV). This enables a house with a HD-DVR to be controlled by other HD receivers in the building.
There are many other benefits that come with having a DIRECTV SWM system, which include:
- Cable distribution is easier using splitters, which saves the amount of cable needed. This, in turn, saves you money.
- Less cable used means no more cutting multiple holes into your walls, which is typical of older setups.
- SWM makes it possible to use smaller client devices that save power.
- It allows for sharing network information, which enables interactive features.
- SWM lets the client schedule recordings on the DVR.
- All current DVRs feature built-in Broadband DECA so an external one is needed only for older equipment or cases where the DVR can’t reach your home network.
