Dynamic SMPS

Introduced in Wi-Fi CERTIFIED 6 Release 2, dynamic SMPS enables turning on and off receiver chains much more rapidly, offering better power savings. The data transmission sequence starts as a single spatial stream and Request to Send/Clear to Send (RTS/CTS). After receiving the packet, the addressed station (STA) goes to maximum capability. The IoT device that this is not addressed to goes into sleep mode.

20 MHz Station (20 MHz STA)

Wi-Fi 6 introduced 20 MHz STA, a power-saving device category for IoT devices. A typical channel has eight slices, and depending on need, pieces are assigned to IoT devices. Devices benefit from less contention, longer battery life, and lower latency.

In technical terms, a 20 MHz channel using orthogonal frequency-division multiplexing (OFDM) technology has 242 tones or useful subcarriers. They are sub-divided into smaller groups called Resource Units (RUs). The RU can be as small as 26 tones. The access point (AP) can now assign these smaller RU concurrently to IoT devices needing only a small bandwidth.

Broadcast target wake time (TWT)

The AP creates wake-up schedule groups and lets IoT devices join them. It is helpful in broadcast traffic scenarios and helps the IoT devices sleep between Wi-Fi transactions, conserving battery life, achieving low latency, and improving airtime efficiency.

Basic Service Set (BSS) Max Idle period

An IoT device associated with an AP must wake up to receive a Delivery Traffic Indication Message (DTIM) for beacons and group transmissions before the AP declares it a bad connection and disassociates. The BSS Max Idle feature permits an IoT device to doze for up to 80 hours, increasing the timeout for inactive connections and improving battery life.

Wi-Fi CERTIFIED 6 delivers IoT and IIoT advantages

Wi-Fi CERTIFIED 6 Release 2 aggregates the best in power-saving features.  Its technological features position Wi-Fi CERTIFIED 6 Release 2 as a powerful support to IoT and IIoT devices and services - reduced wake time for IoT devices, less contention, longer battery life, and lower latency. Wi-Fi CERTIFIED 6 Release 2 provides numerous advantages to the worlds of IoT and IIoT.

He has over 25 years of experience in SoC architecture, embedded software, broadband, and wireless. Saju has an MS in Software Systems from BITS Pilani, India, and CWNA and CWAP wireless certifications.

MaxLinear offers Wi-Fi SoCs and Wi-Fi reference designs and are designed to meet the IEEE 802.11ax standard and have achieved Wi-Fi 6, Wi-Fi 6E, and Wi-Fi 6R2 certification. They support multi-Gigabit Wi-Fi and offer up to 4 streams of 6GHz spectrum with 160 MHz channel support creating higher capacity. In addition, these SoCs provide the ability to connect up to 256 clients simultaneously, enabling a high-quality user experience for a growing number of connected devices. These Wi-Fi SoCs are optimized for the AnyWAN™ SoCs and the Puma™ 7 Family to fully offload the wireless traffic with zero CPU utilization. It frees up the CPU performance for advanced services such as security, analytics, photo/video hosting, and parental controls while delivering a consistent user experience. 

In 2021, Wi-Fi Alliance^®introduced QuickTrack as a new path for Wi-Fi CERTIFIED^™ testing. QuickTrack provides a simpler, lower cost option to achieve Wi-Fi^® product certification. QuickTrack allows members to build products based on Qualified Solutions — modules, chipsets, and other solutions which have undergone prerequisite testing. This testing can be completed at an Authorized Test Laboratory (ATL) or member testing site.

With more than 4.4 billion Wi-Fi devices shipping this year alone, interoperability among products is more important than ever. Users and enterprises will have more devices and will expect these devices to work well together, regardless of brand. QuickTrack has numerous benefits for product developers that want to bring quality Wi-Fi devices to market more quickly while:

• Lowering testing costs by reducing time needed to complete testing
• Avoiding redundant testing of core Wi-Fi components previously tested in a Qualified Solution
• Ensuring Wi-Fi CERTIFIED products continue to meet certification requirements throughout the product life cycle

Members may download the QuickTrack Test Tool software to a QuickTrack Test Tool platform, such as a computer or laptop. This tool allows members to run prescribed conformance testing on products, helping reduce costs associated with test bed purchases. Member companies can integrate the QuickTrack Test Tool into product development quality testing processes, and members may use the QuickTrack Test Tool to gain Wi-Fi CERTIFIED status for products.

Members can choose the best certification option to meet their needs: QuickTrack, FlexTrack, and Derivative paths provide options in testing methods and test locations. All Wi-Fi Alliance certification paths require WPA3™ security, ensuring members can bring secure, interoperable products to market using a testing option that works best for their company.
