Qualcomm announced two WiFi solutions that support next-generation standards --802.11ax, including network infrastructure IPQ8074 system-level chip (SOC) and QCA6290 for the client terminal, according to Qualcomm, they are the first Publish companies that support end-to-end commercial solutions for 802.11ax.
WiFi has almost become an indispensable part of mass life, but with the increase in the number of devices on the connection network, the situation of the WiFi network is more serious.
Rahul Patel, general manager of Qualcomm connection technology department, "WiFi network will become more crowded, we focus on R & D products with higher capacity utilization, improve user connection experience, this is undoubted to be a blessing for consumers .
Next generation Wi-Fi standard 802.11ax, not only can expand network capacity and can increase the utilization of Wi-Fi spectrum. Qualcomm is about to launch a new standard WiFi chip supports routers and client connections. According to Qualcomm Provide information, new products will increase WiFi network capacity through high-order modulation and advanced scheduling, making its cellular technology play an important role in a new generation of WiFi chips.
In addition, Qualcomm represents the impact between users by scheduling, which can alleviate the network crowding problem of WiFi users in the uplink.
What is the performance of IPQ8074 and QCA6290?
According to Lei Feng.com, IPQ8074 is a business-oriented router SOC, which can achieve more than 4 times user throughput for WiFi terminals, with a rate of 4.8Gbps; it adopts MU-MIMO 12 stream solution: 8x8 5GHz plus 4x4 2.4GHz, all multi-input multi-output communication systems are available in uplink and downlinks.
The chipset uses self-organizing network technology to reduce harmful interference with intensive areas with multiple overlapping WiFi access points. Patel representation, by scheduling, IPQ8074 router can improve the performance of all WiFi access points in a region, even if it is not 802.11 AX WiFi access point can also be improved.
A 14nm design process, integrated 11AX RF, MAC and baseband, plus quad-core 64-bit A53 CPU and dual-core network accelerator to provide full-load sharing 11AX subsystems.
The QCA6290 is the SOC for consumer equipment. It is manufactured with 28nm process and supports 2x2 802.11ax connections, parallel dual-frequency operations, and QCA6290 provides 4 times throughput compared to the current most advanced WiFi chip.
In addition, the QCA6290 can provide up to 1.8 Gbps peak speed, and power consumption can be reduced by two-thirds of the Power consumption of 2,000 Gbps by binding 2.4 gHz and 5 GHz band (1024-QAM).
Lei Feng.com IoT Technology comments also understand that IPQ8074 and QCA6290 will be sampled in the first half of 2017, and IPQ8074 router may be in the market this year.
WiFi's three new technologies achieve better connection
First, optimize orthogonal frequency division multiple access technology
The orthogonal frequency division multiple access is part of the LTE standard, and now Qualcomm introduces the technology into WiFi. It is well known that the current WiFi router uses the time division multiplexing algorithm, which can serve the different clients at different times; and the orthogonal frequency division multiplexing can not only divide the bands into multiple sub-bands, but each sub-band is given to one User-specific, you can also optimize multi-user communication.
Patel said: "If you have a 20 MHz client and a 40 MHz client, and you have 80 MHz channels to make the client run, the channel will be divided into 20 MHz and 40 MHz, support two customers. End work at the same time. "
Second, high-order modulation method
802.11 AX also brought higher order modulation for WiFi, using 1024 orthogonal amplitude modulation. Patel said that 1024 QAM's higher speed will make a significant increase in performance and throughput in terms of performance and throughput.
Third, wake-up technology
802.11 AX can make WiFi access points and user equipment with a more lasting battery life. 802.11 AX allows when the device is negotiated and how long it is waken, and or receives data. Therefore, the device is in a sleep state when there is no need to work.
