A Matrix relay is a device that helps you extend the range of your wireless network, allowing you to operate at greater ranges or within a blackout zone. They come in a variety of shapes and sizes, from small handheld personal devices no larger than a credstick to massive systems that require a semi trailer to move. Hackers have discovered that these also work really well as signal boosters, allowing them to cut through Noise caused by jamming and distance.
A Matrix Relay that is connected to your PAN essentially allows you to be in two (or more) places at once, as far as the Matrix is concerned. Setting one up requires a Major Action, and if you wish to conceal activating it that requires a Stealth (Palming) + Agility test.
If you move away from your Matrix Relay, determine if there is any Noise directly between you and your wireless relay due to distance, jamming, or other effects. If the Noise level exceeds the Matrix Relay's rating, then you are out of range. You benefit from a stronger signal if you're not at the edge of the relay's range. If the relay's Rating exceeds the Noise affecting your connection to it, reduce all further Noise penalties by that amount.
If you're within 100 Meters of your Matrix Relay, its full Rating is available to boost your signal. Reduce your Noise level by the Matrix Relay's Rating while it is active.
A Matrix Relay can be restricted by its owner for personal use. If access is allowed, a number of users equal to it's (Rating x 3) may connect to one.
