Ke Hobane'ng ha Wi-Fi e Matla a Tlase

Historically, Wi-Fi has been a power-intensive wireless technology, prohibiting its use in energy-efficient and resource-constrained applications. However, the dramatic growth of IoT and the evolution of the energy-efficient Wi-Fi 6 protocol generation are coinciding and changing the course for low-power Wi-Fi. With Wi-Fi 6, finally there is a simple, battery-friendly, and high-throughput way for developers to connect smart IoT devices to the cloud without bridges and protocol translations.

Wi-Fi Challenges in the IoT
Buyers seek energy-efficient, sustainable, and cost-effective products. To reflect the increasing awareness of green initiatives, new energy regulations are constantly enforced, increasing product development costs. The main challenge for the designers and developers of Wi-Fi IoT devices and smart appliances lies in power consumption.

Mohopolo oa Moqapi oa Matla a Tlase oa Wi-Fi
The concept of low-power Wi-Fi design can be divided into three groups. First, low-power Wi-Fi design begins from the functional requirements of your IoT application. The second groupcontains the advanced low-power features and capabilities that SiWx917 can offer for IoT device makers. The SiWx917 features can be divided into multiple sections covering the product architecture, power management, peripherals, memory, and more. Finally, in the core of the low-power Wi-Fi design concept there is the Wi-Fi protocol, providing many settings to play with when optimizing the power consumption for the IoT application. These three areas of low-power Wi-Fi design finally constitute the overall energy efficiency for your IoT device.

Examples of Power-Gating Options ho SiWx917

MCU power-gating: In the PS0 shutdown, PS1, and PS4/3/2 sleep modes, the CPU is power-gated, reducing power consumption significantly. During MCU power-gating, SRAM can be retained in the sleep mode, but not in the shutdown mode.

SRAM power-gating: In the total SRAM of 672kB, there is a specific section from where designated portions can be power-gated, dividing it into multiple power domains.
Peripheral power-gating: In lower power states, unnecessary peripherals can be power-gated.

Tshupa-nako
Clock-gating is a power-saving technique that allows the device to selectively disable clock signals to specific blocks to reduce power consumption when they are not in use. As opposed to power-gating, clock-gating enables faster wake-up of the blocks that are in standby while power-gating saves more energy but comes with a wake-up latency penalty. The exact implementation and control of clock-gating may vary depending on the specific operating mode and the current power state of the SiWx917.

Network Wireless Processor

The NWP on the SiWx917 is an independent processor that runs the wireless protocols, networking stacks such as TCP/IP, TLS, and MQTT, and security engine, offloading these tasks from the application MCU. It also serves various protocol keep alive protocols, allowing the application MCU sleep longer. The NWP has several power modes designed to help developers optimize power consumption based on network activity and application requirements.
On high level, NWP’s power states can be divided into active/high-performance states and sleep/low-power states. The active states can be in one of the three modes: transmit, receive, or listen. The sleep states can be either connected or unconnected, depending on whether the device should maintain its connection on the Wi-Fi network. For unconnected sleep, the NWP can be in two possible states: with SRAM retention or without SRAM retention. When in connected sleep state, NWP always retains RAM and wakes up based on the DTIM or TWT interval configurations. The NWP can assume three alternative power save profiles (PSP), e etsang qeto ea hore na e fumana joang data e buffered ho AP ka mor'a hore e fumane beacon e nang le TIM bit set.
Max PSP: Data retrieved via power save polling (PS-Poll) frames. Saves power but increases delay and reduces throughput.
Fast PSP: Streamlined data retrieval without polling. Client transitions to the active state and sends a null data frame to the AP for data retrieval.
Enhanced Max PSP: If the AP acknowledges PS-Poll but does not deliver buffered data within 20 ms due to e.g. an interoperability issue, the NWP switches to the active state, and sends null data frame, and waits for Monitor Interval time to retrieve the buffered data.

Matla a Matlatage le Frequency Scaling
Matla a matlatage and frequency scaling allows adjusting the clock frequency of the SiWx917 processor and other blocks on the chip to balance between power consumption and performance for the application – for instance, using a high-performance mode when executing computationally intensive tasks and switching to a power-save mode during idle periods to conserve energy. The SiWx917 can be configured as either power-save or performance mode. After each state change, the clock sets into power-save mode by default.

SRAM Partitioning
The SiWx917 features a total of 672kB of SRAM which can be segregated into different areas based on power to reduce current consumption. In addition to the regular SRAM areas, there are two main power-saving areas: low-power (LP) SRAM of 320 kB and ULP SRAM of 8 kB. Both are further partitioned into multiple domains consisting of one or several banks allowing flexible and energy-efficient power management. The power of these SRAM domains can be controlled flexibly in different ways depending on the power state. In the Sleep mode and PS1, both the LP SRAM and ULP SRAM can be retained. Neither LP SRAM nor ULP SRAM can be retained in the PS0 shutdown mode.

TIMs are present in every beacon indicating that there is pending data for the client in the AP.

If the LI is set, the client wakes up upon the LI interval to check whether there is data for them on the AP. If the LI is not set, the client wakes up per the DTIM interval set by the AP.
The client goes back to sleep after the data is retrieved.
Also, the data retrieval process defined by the power save profile (PSP) ho NWP e ama tšebeliso ea matla.

Nako e Lebeletsoeng ea ho Tsoha (TWT)
In the legacy power save modes such as DTIM, Wi-Fi 4 clients go to sleep and wake up at predefined intervals to check for incoming data and transfer data regardless of the wake-up schedules of other clients. With Target Wake Time (TWT) in Wi-Fi 6, the clients negotiate the wakeup scheduling with the AP, ensuring no two clients wake up at the same time. This method helps avoid packet collisions, thus reducing retransmissions and, in turn, reducing the current consumption for all the clients. The multicast TWT feature enables to set several devices to be awake at the same time. In general, TWT allows Wi-Fi clients to remain in sleep for longer durations, increases power efficiency on connected clients, and reduces network congestion.

Ho lokisa TWT ka bomong ho SiWx917

Manual TWT Configuration: The TWT parameters such as sleep duration, wake-up duration, and wake interval are calculated based on the TWT specification parameters configured in the application.
Automatic (Auto) TWT: A Silicon Labs implementation that configures TWT parameters automatically based on the application requirements such as the average throughput and RX latency. Based on these inputs, the NWP configures the TWT parameters and negotiates them with the AP. The Auto-TWT also checks if the TWT is optimal for a specific combination of latency and throughput parameters. If deemed inefficient, legacy listen Interval-based power saving (DTIM) is enabled instead of the TWT. Auto-TWT is recommended for better throughput, interoperability, power efficiency.

A Wi-Fi 6 client that has subscribed to a TWT agreement should not transmit outside of its service period (SP) to reduce the risk of media contention with other devices. Adhering to the TWT improves the energy efficiency of the device, and other Wi-Fi 6 devices in the network with a TWT agreement.
If a Wi-Fi 6 device is expected to transmit frequently with a short notification time (e.g.
a few seconds), a short TWT interval is recommended. If the occurrence of low-latency transmissions is very sporadic (e.g. fire alarm), transmitting outside the SP could turn out to be a more energy-efficient solution. However, in this case a power consumption penalty should be factored in due to potential media contention with other devices.
If a Wi-Fi 6 device is expected to receive a large amount of data (e.g. firmware update), TWT teardown or re-negotiation of TWT agreement should be considered. The additional procedure increases power overhead, but due to rare occasions, the impact on the overall power consumption is limited.

Ho Sebelisa DTIM le TWT Neng?
Leha Wi-Fi 6 le TWT hangata li khothaletsoa lits'ebetsong tsa IoT tsa matla a tlase, mekhoa ea ho boloka matla a Wi-Fi joalo ka DTIM le eona e na le sebaka sa eona. Tafole e ka tlase e fana ka malebela a hore na u khetha mokhoa ofe.

Ho Sebelisa DTIM Neng?

Wi-Fi 6 and TWT is not always supported or enabled by Wi-Fi routers. However, DTIM is a legacy functionality that is generally supported on Wi-Fi routers.
When the network traffic is very low, the overhead of negotiating and maintaining TWT
(depending on TWT settings) is not worthwhile. DTIM does not require negotiation.

When there is a lot of unpredictable network traffic
Use DTIM when there are many devices not supporting TWT, because they can potentially collide with the service period of TWT-enabled clients.

Ho Sebelisa TWT Neng?

When the IoT application or use case can tolerate a long sleep time, TWT can save energy
When there are a lot of TWT-enabled clients in the network and the wake-up times can be arranged so that they won’t overlap. This ensures a more efficient radio resource utilization, saving power.
