Fluctuating blood pressure often signals health problems. For older adults and patients with hypertension, it is even more important to monitor and track their blood pressure regularly. Thus, many doctors and experts suggest that people at higher risk should buy blood pressure monitors to check their blood pressure at home.

There are two types of blood pressure monitors: manual and digital meters. Manual meters, including mercury and aneroid manometers, are used in conjunction with a stethoscope. Since taking a blood pressure manually is relatively complicated, manual meters may not be the best choice for non-trained users.

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.

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?

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.
