A brief introduction to Bluetooth applications: BT Pointer and its interoperability issues

Allion Labs / Flash Liu

Bluetooth is a personal wireless communication technology commonly used in the connections of PCs, smartphones, and personal mobile devices for information transfer and exchange. The Bluetooth SIG introduced the newest Bluetooth 5.0 in 2016, boasting an effective transmission distance of 300 meters and speed of 2Mbps.

Ever since Bluetooth 4.0’s adoption of the Low Energy Technology, products that support Bluetooth have gradually increased. In recent years, the application of Bluetooth has expanded from general computer-related merchandise to medical and home care, vehicle-mounted devices, and IoT smart home appliances, etc.

Operating your Wi-Fi network on the 5GHz band? Make sure you deploy DFS first!

Allion Labs/ Flash Liu

The under-capacity, over-crowdedness and poor efficiency of the 2.4GHz band have long been common knowledge. The number of channels on the 5GHz is greater than that one the 2.4GHz. However, a large portion of these channels is DFS channels. The advantage of the 5GHz is reduced by more than half if the DFS channels are not in use.
What exactly is DFS? Why is it so influential?

How much do you know about Bluetooth Intellectual Property?

Intro
Since the release of Bluetooth 5 in 2016, it has been widely adopted by the global IoT community to make all kinds of smart devices. Bluetooth 5 delivers a faster solution as its transmission speed is 4.2 times faster than the previous versions, with its range quadruples while boosting the capacity of message broadcasting by 8 times.

Additionally, Bluetooth 5 supports indoor positioning and navigation. By integrating with Wi-Fi technology, Bluetooth 5 can locate objects indoor and is accurate to within 100 m. Whether it is data synchronization With features such as high-performance, low-power, low-cost, better security, and easy-to-develop, Bluetooth 5 has become the priority of many smart home appliance vendors.

But, before we move on, do you know that Bluetooth logo is an intellectual property?

Everything you need to know about Wi-Fi

Wi-Fi has become an indispensable part of our lives. Before Wi-Fi was invented, wireless connections were conducted via infrared technologies. Users had to carry their devices with them and sit next to each other so that the data could be transferred wirelessly. With Wi-Fi, users can now transfer data wirelessly even if they are a few meters, or even hundred meters away from each other. This “wireless” experience has definitely brought convenience and fun to users worldwide.

The Evolution of Wi-Fi
The application of Wi-Fi was first established by the IEEE, which ratified the CSIRO invented Wi-Fi—802.11 as the industry’s standard Wi-Fi technology in 1999. Since then, all Wi-Fi technologies are based on the 802.11 standard, and the Wi-Fi Alliance has become the key player in promoting and solving issues related to Wi-Fi connection and interoperability. Thanks to the early established standardization, the Wi-Fi technology has advanced significantly in just 20 years and made a huge impact on our lives.

The Key to Better Gaming Displays—Getting Your Displays Tested and Certified

The gaming industry is growing fast with new technologies, and the gaming appliance market is also booming as the gaming industry grows. For instance, the demand of high-quality displays has been soaring these days.

According to a report released by WitsView, Trendforce, the global unit shipments of gaming displays in 2017 was 2.5 million, with an annual growth of 80%. The shipments are expected to increase by 1 million by the end of 2018, with a total of 3.7 million units on the market.

The fast-growing gaming market surely has brought more opportunities for the peripheral appliance and display vendors. However, quality has also become customers’ prior concern and thus it is important that vendors put more emphasis on quality assurance and look out for potential risks.

Can Your Smart Assistants Work With Other Devices? A Test Analysis from Allion’s Interoperability Validation

As we mentioned in last article: Smart Enough? The Three Most Frequent Issues in Smart Assistant Applications, smart assistant can be vocally activated to provide entertainment support, help search information, and control other smart devices in houses, offices, or hotel rooms. Generally, a smart assistant, to complete these tasks, has to work with other devices, such as going online with wireless access points (AP) or synchronizing with smart phones via Bluetooth. However, we found several interoperability issues after paring up six smart assistants with 20 APs and 20 smart phones. In this article, we argue that, even for the products that have been certified by Wi-Fi and Bluetooth, interoperability issues can occur during the complex matches among the various products in the market.

Smart Enough? The Three Most Frequent Issues in Smart Assistant Applications

Voice recognition has become the prevalent technology for remote authentication. To fulfill people’s imaginations for “convenience,” tech giants such as Amazon, Google, and Apple started to develop their own voice recognition systems and have invented and brought “Smart Assistant” to the market.

Generally, a smart assistant can be vocally activated to provide entertainment support (e.g. music and radio), help search information (e.g. wiki, translation, and recipe), and control other smart devices in houses, offices, or hotel rooms. These clever helpers later become the focus for those manufacturers who attempt to step further in the IoT era. Read more

Protect Your Eyes in a Better way – Allion Test Report of Blue Light Filter Apps

With the flourishing of display technology nowadays, digital device makers tend to produce bright and vivid screen by using LED backlighting technology. However, you should be careful since this “eye-killer” can emit very strong blue light rays, which harm your eyes. In fact, studies have shown that prolonged exposure over time of blue light will cause digital eye strain, such as dry and irritated eyes. Although there are a large numbers of blue light filter apps (also known as Night Mode) that allow users to protect eyes, their efficiencies are still questioned. In this article, Allion argues that these apps can be useful tools for filtering out blue light. First, we will explain what blue light is. Then we will run tests after activating these apps.

Validate your Smart Device with Real World Factors: Allion’s Heat Map Analysis Program

According to research firm IHS Markit, the number of IoT devices will increase on average 12% each year from 27 billion in 2017 to 125 billion in 2030. As more devices go on the Net, the limited wireless channels have become more congested that brings plenty of connectivity issues to the real-world and further deteriorates user’s experiences.

Unlike one-to-one communication of traditional devices, communication of IoT devices has become one-to-many. The performance of IoT devices should involve in three factors: product capability, network connectivity and user environment/ behavior. Vendors thus need a new methodology to verify products before launching to the market. This article will discuss a new methodology of IoT device validation “Heat Map Analysis”, which is used to perceive real-world factors and further discover and resolve common wireless connectivity issues.
