Interconnect and low power are key to wearables

The strong impact of wearable devices has triggered a new round of market looting by major manufacturers. In order to seize business opportunities, major manufacturers have laid out various new products or solutions for wearable devices. The combination of wearable devices and people is closer than previous products, which requires wearable devices to adopt a new human-machine interaction technology to achieve a harmonious human-machine, which is the current research on wearable devices. Hot issues and difficulties that must be overcome.

The human-machine interaction of wearable devices is mainly reflected in the interconnection of products, not only to consider the interconnection with the data hub, but also to integrate with existing personal communication terminals (such as smart phones, tablets, etc.). This requires that the connectivity of wearable devices must be more flexible and adaptable, and that the integration with existing personal communication terminals needs to be fully considered. This interconnection puts more emphasis on the wireless network of wearable devices. High requirements. For example, it is necessary to be able to perform decentralized control. This is because each communication terminal has certain computing processing power and storage capacity (and with the development of very large scale integrated circuits, the performance in this area is bound to be further improved), and it is more human. The user can select the appropriate primary communication device to control the entire network according to different applications, convenience levels, and personal preferences.

Jeff Baer, ​​director of business development at Broadcom's Embedded Wireless and Wireless Connectivity Division, said that the wearable market needs to be low-power, location-aware, and interconnectable whenever and wherever possible. The ability to connect these products to smart devices is critical because it not only provides a window into which these devices collect data, but also serves as a central hub for sending this data to the cloud. The use of wireless technology to send and receive this data on smartphones and tablets can greatly reduce the data processing needs and power consumption requirements of wearable devices, while also reducing costs and costs for manufacturers and consumers. Wireless connectivity has become the key to enabling the great potential of the wearable market to be released.

To this end, Broadcom has released a portfolio of embedded device Internet wireless connectivity (WICEDTM) products, including:

· WICED Direct integrates Wi-Fi DirectTM into the WICED platform, enabling OEMs to quickly develop wearable products and seamlessly communicate with the cloud via smart mobile devices.

Bluetooth Smart System Single-Chip (SoC), BCM20732, connects battery-powered devices such as heart rate monitors, electronic pedometers, door locks, lighting, proximity detection alarms

· Wi-Fi System Single-Chip (SoC), BCM4390, integrates WiFi functionality into low-power consumer electronics including sports, fitness, security, and security applications, as well as slow cookers Or lighting, etc.

· The WICED Intelligent Development Kit, which integrates the Bluetooth Smart System Single-Chip (SoC) and embedded WiFi, assists OEMs in developing wireless connectivity for all types of battery-powered devices.

Utilize Broadcom's Embedded Device Internet Wireless Connectivity (WICEDTM) portfolio to enable connectivity between different product types through Wi-Fi, Bluetooth and Bluetooth low energy technologies in smart home, logistics, consumer electronics, surveillance, healthcare, etc. The field can be widely used.

Compact and portable is an important feature of wearable devices, and for reasons of size, the challenge of power consumption is of particular concern for these resource-constrained, battery-operated products. The average working time of a battery cycle depends on the capacity of the battery on the one hand and the energy consumption of the device and the efficiency of use of the power supply on the other hand.

About low-power Jeff Baer said Broadcom's embedded Wi-Fi solution not only has the industry's highest level of integration, but also significantly reduces power consumption. "With as little power as possible to accomplish as many communication tasks as possible," Broadcom's chips are designed for this purpose, and the chips consume only the power needed to perform a specific task, making wearables extremely high. effect.
