Netgear has announced availability of its 3DHD wireless home theater networking kit, capable of delivering jitter-free 1080p HD video streams throughout the home with no new wires.
The growing popularity of Internet-capable TVs and other home-theater equipment, including Blu-ray players, video game consoles and digital media adapters, often presents consumers with a big hurdle: The home router or gateway which provides an Internet connection is in one room of the house while the home theater system is in another – sometimes separated by several walls or even on different floors. Running Ethernet cables through the house is expensive and time-consuming.
Netgear 3DHD wireless technology includes:
- Four transmitters and four receivers built into each 3DHD wireless adapter for Multiple Input Multiple Output transmission (4×4 MIMO), significantly increasing Wi-Fi range and reliability.
- Dynamic digital beam forming to steer and target Wi-Fi signals toward the receiver rather than broadcasting the signals in all directions, boosting range.
- Space Time Block Coding (STBC) to send multiple and redundant copies of the same data across different paths, minimizing packet loss and improving video reliability.
- A feedback control loop that allows the transmitter to adjust its activity based on responses from the receiver, for reliable video streaming even in a changing or high-interference wireless environment.
The result is carrier-grade range and reliability, capable of sending multiple HD video streams across the home through multiple walls – such as the two simultaneous HD video streams required for 3DHD movies and broadcasts – with virtually no data loss. The 3DHD wireless technology is robust enough to provide a reliable wireless bridge in homes as large as 5,000 square feet.
