Adding SDIO Support in ath10k Driver – Another Silex Initiative for Mass Market Wi-Fi

Posted by Safi Khan on 2017-08-16 07:48:05

Customer feedback is important to us at Silex and whenever we can do something extra that makes them happy, it makes us happy! A recent example of our customer focus at Silex is the ath10k initiative. I want to share  the technical details of this initiative and how our engineering team overcame some of the challenges to making this work. We have had a long history of supporting open-source drivers for Qualcomm Atheros low power Wi-Fi radios dating back to ath5k for some of our legacy modules. Since then, we have supported ath6k, ath9k, and now finally, I want to talk about ath10k.

60GHz WiFi (WiGig) for the Rest of Us – SX-PCEAD 802.11ad Module from Silex Brings 4.6Gbps Speeds to New Markets and Applications

Posted by Safi Khan on 2017-08-14 06:40:48

The SX-PCEAD implements the IEEE802.11ad WiFi/WiGig standard in 60GHz band for high speed communication. It is based on the QCA6320 chipset from Qualcomm Technologies, Inc.. The 60GHz frequency band supports much wider bandwidths than those of the 2.4GHz or the 5GHz bands. Thus it can achieve a maximum PHY data rate of 4.6Gbps using 2GHz bandwidth. Signals in 60GHz band do not easily penetrate walls etc. so it is an ideal technology for short range in-room use cases such as IP docking, transferring multimedia content such as 4K videos and images, video streaming and projection, insanely fast movie downloads from kiosks, high resolution medical imaging, etc.

Add Ultra Low Power WiFi Using UART AT Command Set

Posted by Safi Khan on 2017-08-04 19:38:57

Silex has released a new version (12.2.x) of our UART AT Command Set for Qualcomm's Ultra Low Power WiFi IoT Soc QCA4010. Our new product is called SX-ULPGN-EVK-AT. The SX-ULPGN-EVK-AT is an evaluation kit for our SX-ULPGN module based on the QCA4010. 

Using our new SX-ULPGN-EVK-AT, customers can quickly evaluate our AT Command Set. They can add a serial-to-Wi-Fi converter for their existing MCU based designs without porting any host driver. SX-ULPGN can offload the host MCU by performing all of the Wi-Fi related tasks such as low power WiFi network stack, security, and authentication.

Top Features:

JTAG OTA Programming Station and AP Modes
Open System WPA-PSK, WPA2-PSK None, WEP, TKIP, and AES(CCMP) Enrollee (PIN/PBC)
IPv4, IPv6, DNS, SNTP, HTTP SSL/TLS, DHCP, and WPS IEEE802.11 Power Save Mode
Suspend (Store Recall, Power Off Suspend(Sleep Wakeup, Host Deep Sleep) TCP/IP Offload

Silex Technology Introduces Next Generation Ethernet to WiFi Bridge and USB to WiFi USB Device Server

Posted by Safi Khan on 2017-03-28 09:03:07

Santa Ana, CA., March 28, 2017 – Silex Technology America, Inc., a global leader in wired and wireless networking solutions, today introduced the BR-310AC and the DS-520AN respectively. The BR-310AC is a wireless bridge which enables any Ethernet device to become an 802.11a/b/g/n/ac wireless network device, giving the freedom to place it anywhere in your facility. The DS-520AN allows any USB device to be used over a dual-band wireless or gigabit wired network as though it was connected to a computer, thus eliminating the 5m USB cable limit.

Catching the Perfect Wave of 802.11ac

Posted by Safi Khan on 2016-12-12 20:37:06

Time to Move to Reliable, Next-Generation, Enterprise Wi-Fi Networks

802.11ac has quickly become the current Wi-Fi standard as 802.11n gradually moves closer to being a legacy standard. It is therefore important to understand the key features and benefits of 802.11ac. This paper explains the top reasons to move to 11ac and helps you understand how Silex is bringing an extremely reliable, next-generation, enterprise-grade SDIO Wi-Fi module "SX-SDMAC" based on industry-leading Wave2 MU-MIMO 802.11ac technology.

11ac is the first Wi-Fi standard to cross the gigabit-per-second throughput barrier. It increases the throughput and capacity of a Wi-Fi Access Point (AP).

Silex Releases Version 1.5.4 of the SX-ULPGN UART AT Command Set

Posted by Safi Khan on 2016-10-31 23:19:15

The SX-ULPGN is an ultra-low-power hostless Wi-Fi IoT module with 802.11 b/g/n support. This low power Wi-Fi IoT module is based on QCA4010 System-on-Chip (SoC) from Qualcomm. Our close relationship with Qualcomm and other partners enables us to provide support for our modules that is not available elsewhere.

The SX-ULPGN also supports a hosted mode for external MCUs with the Silex UART AT Command Set for a cost-effective serial-to-Wi-Fi connectivity addition to already designed IoT solutions with host MCUs.

Based on positive feedback and requests for additional features from our customers, we have now released an update to the UART AT Command Set (Version 1.5.4). This new version adds commonly used networking features like HTTP client and access to peripherals like ADC, PWM, and GPIOs of the SX-ULPGN and make them available to the external Host.

Some of the key features of the Silex AT Command Set are highlighted below:

  • No Host Driver Required for Rapid Customer Enablement
  • Expands SX-ULPGN's Market Reach into Cost-Effective Hosted MCU Based IoT Solutions

Hosted or Hostless IoT Wi-Fi Devices? The Decision is Critical

Posted by Safi Khan on 2016-08-08 18:16:31

The Internet of Things (IoT) is a quickly growing market segment, and IoT applications often require smaller size, lower cost, andlower power consumption to address many small-but-constant battery operated applications such as home automation controls, sensors, and medical devices. As a result, these devices offer a unique variety of connectivity options beyond what were available to once-typical wireless devices. One of these options involves choosing to create either a hosted or a hostless IoT Wi-Fi device.
