SX-582 - The Next Generation Embedded Intelligent Wireless Module

Posted by Babar Hashim on 2017-02-02 01:25:47


SX-582
is a high-performance Serial/Ethernet to Wi-Fi embedded module, based on the Qualcomm Atheros AR6234 system in package (SiP) solution, that provides dual band 802.11n wireless connectivity for device manufacturers who want to add robust and secure Wi-Fi.

It features a 32-bit 454 MHz Freescale i.MX28 processor with an 802.11a/b/g/n radio, a complete TCP/IP network protocol stack, and an optimized QCA6004 wireless radio driver and security supplicant in a self-contained hardware package. A major advantage of the SX-582 is enterprise security, including WPA2 with 802.1x authentication, which enables it to be used on almost any customer’s network without compromising security. We have also added multi-client bridge support to the product as a standard feature.

Code RED - Radio Equipment Directive, that is!

Posted by Ron Tozaki on 2017-01-31 01:44:35

ALERT… Come June 13, 2017 the current directive regulating radio equipment will be repealed and new requirements will come into law and all new products will need to comply with the updated directive. We are now less than 6 months away and have to make sure that all products being sold or placed into service in Europe MUST comply to RED (Radio Equipment Directive).

 

Summary of Changes?

Please note that to sell Wi-Fi products into the EU you must be compliant to RED and not R&TTE. One must understand what is being changed so necessary steps can be taken to get Wi-Fi products in compliance. The four basic standards for WIFI are changing.  They will be officially harmonized and listed in the Official Journal as follows:

As shown above, the 5 GHz standard will not be official until after the mandatory June 13, 2017 transition date so you must obtain an EU-type examination certificate from a Notified Body (NB) which will be an added expense to you.

Why thermal profiles are important for the integration of embedded Wi-Fi radios?

Posted by Babar Hashim on 2016-12-28 16:00:00

What is thermal profiling?

A thermal profile is a complex set of time-temperature data typically associated with the measurement of thermal temperatures. At Silex for thermal profile analysis of our radios we generate heat within the DUT (radio), but running high frequency of data through the radio until the desired steady thermal state is reached. Once the desired steady state is reached the thermal profiles are captured by a FLIR camera.

Power Save Options for Wi-Fi Radios

Posted by Babar Hashim on 2016-12-20 03:49:36

Power Save has always been a part of the 802.11 standard since 1999. The devices it had targeted were a lot different from the wireless devices used today. Back then these devices were primarily laptops with big batteries moving between conference rooms. No thought was made that Wi-Fi could and would be added to small hand held devices being used in all aspects of our life. With the addition of Wi-Fi to mobile devices like cell phones, the power save requirements have changed.

               There is now a greater focus on power saving in Wi-Fi than any previous stage of its existence. The advancements in hardware and application have shaped the power save options available today in 802.11. Let’s look at the some of the techniques used to save power consumption.

               There are four basic operations that a radio can perform that leads to power consumption. Power consumed by each activity increases in the given order (1-4). By controlling how long the radio operates between the below states, a user has some control on how much power his radio consumes.

  • Asleep
  • Idle & awake
  • Receiving
  • Transmitting

Test, Fix, and Enhance: Developing Reliable Enterprise Wi-Fi Solutions

Posted by Keith Sugawara on 2016-12-16 10:37:45

As we all know, all software will have some bugs. Some problems are fairly easy to discover, but others only occur in specific situations, making it difficult to reproduce them or even discover that they exist. At Silex Technology, we test our software in as many scenarios as possible so we can identify and resolve problems before our product gets into the hands of our customers.

 
Sometimes, bug fixes and feature enhancements require modification to the radio source code. As one of 15 Qualcomm Atheros Authorized Design Centers (ADCs), Silex Technology is one of the few companies in the world enabled with radio source code access. This allows us to make tweaks and modifications for reliability and performance that is not available to most of our competitors.

 

Silex Technology brings stability to the Qualcomm Atheros technology used in consumer mobiletechnology today to ensure it can be used in critical, always-on enterprise devices.

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).
