The demand for 802.11ac Netcom equipment with 4 & TImes; 4 multiple input multiple output (MIMO) specifications will rapidly increase. In order to avoid the deployment of 802.11ac routers and access points (AP), which are hindered by the concrete wall of the building, the telecommunications operators in France and the United States have caused a decline in the quality of telecommunications services. They are scheduled to introduce 4 & TImes; 4 MIMO 802.11 in 2014 Ac-standard high-end routers and access points have driven the market heat of related equipment.
Sam Heidari, CEO of Quantenna CommunicaTIons, said that consumer electronics, mobile devices and personal computers (PCs) are equipped with 1,080p and ultra-high resolution (UHD) screens, and as 1,080p and UHD video content surges, end users The demand for transmitting high-quality images through various networked devices will become more ardent, and it is expected to incentivize telecom operators to accelerate the expansion of 802.11ac routers and access points in response to the huge network data traffic in the future; The quality of audio-visual services, to pay more attention to revenue and profit.
Sam Heidari, CEO of Quantenna
Optimistic about the market prospects of 802.11ac routers and access points, chip makers such as Broadcom, Qualcomm Atheros, and Quantenna have competed to launch corresponding chip solutions. Heidari pointed out that most routers and access points that support 802.11ac are equipped with 3 & TImes; 3 MIMO chips. However, in fact, the 4 × 4 MIMO 802.11ac chip solution is superior in terms of coverage, data transmission rate and reliability. , Can better meet the performance requirements of telecommunications operators for 802.11ac routers and access points.
It is reported that the 4 × 4 MIMO 802.11ac chip solution QSR1000 recently released by Quantenna conforms to the 802.11ac Wave 2 specification, including transmission speeds up to 1.7 Gbit / s, with dynamic digital beamforming (Dynamic Digital Beamforming), and four spatial data streams ( Spatial Stream) and multi-user (Multi-user) MIMO technology, so the transmission speed is faster, the transmission distance can be up to 300 feet and the reliability is higher.
Heidari emphasized that the QSR1000's close to 2Gbit / s transmission rate allows different devices to transmit 1,080p and UHD resolution content to each other, and can transmit signals to multiple corners and brick walls to any corner, greatly improving the reliability of the product. In addition, the solution is also compatible with 802.11ac solutions of 1 × 1, 2 × 2, and 3 × 3 MIMO. Not only is it suitable for high-end routers and access points, set-top boxes and Pay TV will also become locked The main application.
Heidari revealed that in 2012, French and American telecom operators have adopted Quantenna's 802.11n chip routers and access points to build wireless local area network (Wi-Fi) infrastructure; currently Netcom manufacturers have built in QSR1000 routers and The access point is getting certification from French and American telecom operators. It is expected that after 8-9 months, if the product successfully passes the certification, the telecom operators will fully introduce 4 × 4 MIMO 802.11 in the Wi-Fi infrastructure in France and the United States. ac chip solution.
