What is Wi-Fi HaLow?
Since its introduction in 2017, Wi-Fi HaLow, also known as 802.11ah, complements traditional Wi-Fi to expand WLAN network with its ultra-low power long range, and secure Wi-Fi connection to support long-range application and large-scale IoT network.

Frequently Asked Questions
In which countries can the SX-NEWAH be used?
The SX-NEWAH(US) obtained the modular certificate for US and Canada. The antenna gain must be 3.4dB or less to apply the certification for your product.
Silex is aiming to make the Wi-Fi HaLow module available in EU and Japan. We will communicate the availability in these regions as the regulatory settlement progresses.
Silex provides the certification service for usage with different antennas or different regions.
How far can a Wi-Fi HaLow radio reach?
We've seen mega-bit-per-second data throughput over a mile at 23dBm transmission power in a relatively clean environment.
The distance will depend on the height of the device placement, radio interference from other devices operating in sub-GHz band (LoRaWAN, RFID, etc.), transmission power, and other factors. Silex will work with customers to assess the viability of Wi-Fi HaLow for specific use cases.
What data throughput can I expect with my embedded system enabled by the SX-NEWAH?
We observe over 8Mbps TCP data throughput with our evaluation Linux driver running on the Raspberry Pi when operating in 4MHz channel bandwidth. With 2MHz channel bandwidth, it will be around 4Mbps. With 1MHz channel bandwidth, it will be 2Mbps TCP throughput.
The throughput will also depend on the CPU's performance in your embedded system. With the i.MX6 ULL operating at a little over 500MHz, the TCP throughput is bounded at around 5Mbps when operating in 4MHz channel bandwidth. With 1MHz/2MHz channel bandwidth, we don't observe much difference between i.MX6 ULL and Raspberry Pi platform.
Outside of the United States, some regions define the duty cycle for radio transmission. The data throughput will be the function of the duty cycle when it applies.
The outdoor performance check with silex EVK is available in the blog.
What do I need to integrate Wi-Fi HaLow network into my existing network infrastructure?
A Wi-Fi HaLow access point is required to associate Wi-Fi HaLow stations. Since Wi-Fi HaLow operates in sub-GHz frequency band, Wi-Fi HaLow stations cannot be connected to legacy Wi-Fi access point or router operating in 2.4G/5GHz band.
Silex offers the AP-100AH that can be easily plugged into an Ethernet switch or router so that the Wi-Fi HaLow wireless LAN can be integrated into your network.
How many Wi-Fi HaLow stations can be connected to a single access point using the SX-NEWAH?
What operating system does the SX-NEWAH support?
The product will include a Linux based driver supporting kernel version v4.14 or FreeRTOS based driver. If any of these do not meet your needs, Silex also specializes in porting drivers to various operating systems and OS versions. Please reach out to us for information on how we can help meet your needs based on your specific OS requirement.
What evaluation platforms are available for SX-NEWAH?
For more detail, please visit the SX-NEWAH Evaluation page HERE.
How can I get the evaluation image?
SX-NEWAH-EVK comes with a SD card with pre-loaded Linux evaluation image.
If you have only SX-NEWAH evaluation board and need the evaluation Linux image for Raspberry Pi, please request it from this page selecting "SX-NEWAH Evaluation Linux Driver Image".
If you need the FreeRTOS evaluation driver image, please request it from this page selecting "SX-NEWAH Evaluation FreeeRTOS Driver Image".
Silex support team is going to send the download instruction no later than 7 days after the request. Please allow us to take a couple of days to review the request.
Is a SX-NEWAH in mini-PCIe card form-factor available?
Does Silex's Wi-Fi HaLow solution support the power saving modes?
Can the SX-NEWAH be driven from a USB host interface of my host controller?
Yes, it can be by using USB to SPI converter IC. Silex has developed a Linux driver for FTDI FT232H USB-SPI converter IC.
Please refer to the application note: How to Set Up the FTDI USB to SPI Bridge for the SX-NEWAH.
Which antennas are recommended?

Can two BR-100AH be connected directly?
The BR-100AH can be connected to the Wi-Fi HaLow access point such as the AP-100AH. The BR-100AH cannot connect to another BR-100AH directly.
Can the AP-100AH and the BR-100AH be interchangeable?
