What is Mimo and where is it used?
MIMO is also planned to be used in Mobile radio telephone standards such as recent 3GPP and 3GPP2. In 3GPP, High-Speed Packet Access plus (HSPA+) and Long Term Evolution (LTE) standards take MIMO into account.
What is the research on multi-user MIMO technology?
Recently, results of research on multi-user MIMO technology have been emerging. While full multi-user MIMO (or network MIMO) can have a higher potential, practically, the research on (partial) multi-user MIMO (or multi-user and multi-antenna MIMO) technology is more active.
What are the advantages of Massive MIMO in a rich scattering environment?
In a rich scattering environment, the full advantages of the massive MIMO system can be exploited using simple beamforming strategies such as maximum ratio transmission (MRT), maximum ratio-combining (MRC) or zero forcing (ZF). To achieve these benefits of massive MIMO, accurate CSI must be available perfectly.
What is MIMO routing?
Routing a cluster by a cluster in each hop, where the number of nodes in each cluster is larger or equal to one. MIMO routing is different from conventional (SISO) routing since conventional routing protocols route node-by-node in each hop.

Are neck massagers safe?
Whether neck massagers are safe or not is an on-going debate. It's important to keep in mind that, if used correctly, a neck massager would do you no harm. However, if you use it for too long or crank up the heat too high, the massager can lead to physical damage.
Are back massagers safe?
Back massagers are safe—so long as you are utilizing them correctly. Healing Arts founder and chiropractor Dr. Alicia Armitstead says that handheld and stationary iterations can address light to moderate muscle pain.
Do self massagers work?
Personal massagers won't improve your game “People often ask me if a handheld massager will improve athletic performance,” says Dr. Calabrese. “The research is clear that these devices have not been proven to improve speed or endurance. In general, they are not used as performance enhancement tool.”
Can I use massager everyday?
You can enjoy a relaxation massage once a year or two days in a row or even twice a day for relaxation without harm. You can benefit from massage sessions once every week or two to keep your muscles, joints and tissues pliable and in good shape.
Can electric massagers cause nerve damage?
Yes, you can damage nerves by massaging your neck, but it's rare and rarely serious.

What is a MIMO?
In radio, multiple-input and multiple-output, or MIMO ( / ˈmaɪmoʊ, ˈmiːmoʊ / ), is a method for multiplying the capacity of a radio link using multiple transmission and receiving antennas to exploit multipath propagation.
What is MIMO in wireless?
At one time, in wireless the term "MIMO" referred to the use of multiple antennas at the transmitter and the receiver. In modern usage, "MIMO" specifically refers to a practical technique for sending and receiving more than one data signal simultaneously over the same radio channel by exploiting multipath propagation .
What is MIMO signal testing?
MIMO signal testing focuses first on the transmitter/receiver system. The random phases of the sub-carrier signals can produce instantaneous power levels that cause the amplifier to compress, momentarily causing distortion and ultimately symbol errors. Signals with a high PAR ( peak-to-average ratio) can cause amplifiers to compress unpredictably during transmission. OFDM signals are very dynamic and compression problems can be hard to detect because of their noise-like nature.
When was MIMO first used?
MIMO is often traced back to 1970s research papers concerning multi-channel digital transmission systems and interference (crosstalk) between wire pairs in a cable bundle: AR Kaye and DA George (1970), Branderburg and Wyner (1974), and W. van Etten (1975, 1976). Although these are not examples of exploiting multipath propagation to send multiple information streams, some of the mathematical techniques for dealing with mutual interference proved useful to MIMO development. In the mid-1980s Jack Salz at Bell Laboratories took this research a step further, investigating multi-user systems operating over "mutually cross-coupled linear networks with additive noise sources" such as time-division multiplexing and dually-polarized radio systems.
Is MIMO a multi-user technology?
Recently, results of research on multi-user MIMO technology have been emerging. While full multi-user MIMO (or network MIMO) can have a higher potential, practically, the research on (partial) multi-user MIMO (or multi-user and multi-antenna MIMO) technology is more active.
Can MIMO be used for wired communication?
Given the nature of MIMO, it is not limited to wireless communication. It can be used for wire line communication as well. For example, a new type of DSL technology (gigabit DSL) has been proposed based on binder MIMO channels.
