North America accounted for 83% of LTE device shipments in 2011, according to Signals and Systems Telecom.
WSJ: U.K.'s 4G Auction a Missed Opportunity for Real Competition
The fact is the marketplace is littered with dozens of novelty watches, all of which tell time well, and which do such things as receive Global Positioning Systems signals, change the channel on TV sets, take pictures and store contact lists like a personal digital assistant.
With most other VoIP systems, voice signals are sent onto the Internet from their origin.
For example, advanced thermostats could turn down ventilation systems based on price signals from utilities, while dishwashers would know to operate only in the wee hours of the morning.
After the Supreme Court decided that cable-TV systems could retransmit broadcast signals without violating copyright laws, Congress in 1976 revised the law to require broadcasters to provide compulsory licenses to their cable counterparts.

These include the frontal cortex (where decisions are made), the motor cortex (which controls muscle activity), the somatosensory cortex (where the sense of touch is located) and the part of the parietal cortex that regulates kinaesthesia (the sense of bodily motion, which is built up from signals from the muscles and the vestibular systems of the ears).
Some cable programmers argued that the FCC's order would make it harder for them to gain access to cable systems if both analog and digital signals of local stations had to be offered.
All planes have batteries, but the Dreamliner needs especially powerful ones because its control systems are driven entirely by electrical signals in place of the hydraulic controls seen on earlier generations of jet.
Under the Federal Communications Commission's requirement, cable operators must either switch to all-digital systems, or carry both the digital and analog signals of local stations in the first three years after the February 2009 conversion.
The software includes an auto-recognition feature that identifies any device plugged into a laptop, from an electrocardiogram machine to an electron microscope, and translates the signals into a form that can be received by hospital computer systems at the other end.
He argues that with antilock brake and stability systems, 100 percent reliability is possible because they merely survey signals from within the car: wheel speed, pressure applied to the brake pedal, and so on.

But he spent three years reverse engineering the flight navigation software that receives ACARS signals to find bugs that allowed him to send his own commands to the systems, either from a software-defined radio that can be tuned to use ACARS or from a compromised airline system.
These systems allow carriers to move data up to 1, 600 kilometers before the signals must be goosed up again.
Home energy management systems allow communication between digital devices and major appliances so customers can respond to price signals sent from the utility.

EnterpriseMobility will allow office workers to remain connected to their company's information systems with the aid of base stations that are placed around the office, picking up radio signals from a number of devices, including Bluetooth-enabled PCs, headsets and Palm handheld devices, Ostergaard said.
He thinks this will have far-reaching implications for the networks, crippling them in their negotiations with cable and satellite systems, which only in the last few years have agreed to start paying fees to retransmit their signals.
