Broadcom unveils new Wi-Fi 7 chip combo for routers and phones
Broadcom Inc. has introduced three new Wi-Fi 7 chips that can be used to equip routers and phones with wireless networking capabilities.
Wi-Fi 7 is the latest version of the wireless networking technology of the same name. It can deliver up to 46 GB per second of bandwidth, double the previously supported maximum bandwidth. The technology also promises to significantly reduce connection latency.
"By adding these three new products, Broadcom enables its customers to build a diverse portfolio of high-performance Wi-Fi 7 products across a broad range of markets," said Vijay Nagarajan, Broadcom's vice president of wireless communications and connectivity marketing.
The first two Wi-Fi 7 chips from Broadcom, the BCM6765 and BCM47722, were designed for use in networking equipment. The former chip is optimized to power home routers. The BCM47722 targets access points, the networking devices that businesses use to provide Wi-Fi connectivity in offices.
The two chips have a similar design. Both feature a quad-core central processing unit based on Arm Ltd.'s processor architecture of the same name. Additionally, both the BCM6765 and BCM47722 include two built-in radios for sending data over a wireless connection.
The chips also include a number of supporting components, according to Broadcom. These components are designed to improve the reliability of a user's Wi-Fi connection.
Wireless signals are weakened as they travel within the router's circuits or wirelessly to the user's cell phone. Therefore, the signal usually has to be enhanced before it can be processed. Broadcom's new chip includes a built-in power amplifier that boosts incoming data transmission for easier processing.
When a Wi-Fi signal passes through components such as power amplifiers, its quality sometimes degrades, which can cause network problems. Routers use a technique called digital predistortion to mitigate such errors. Broadcom's new Wi-Fi 7 chips can delegate the task of performing digital pre-distortion to an external component called a front-end module, an arrangement the company says can reduce power consumption.
The set of radio frequencies that a phone uses to send data to a Wi-Fi router is called a channel. The speed of data transfer is measured using a metric called channel width. Wi-Fi 7 offers twice the channel width of previous-generation Wi-Fi 6E technology, or 320 MHz, which is one reason for its faster speeds.
Broadcom says its BCM6765 and BCM47722 chips both support 320 MHz Wi-Fi connections. They also support multi-link operation, another enhancement introduced with Wi-Fi 7. The technology speeds up connections by allowing devices to transmit data over multiple channels, or sets of frequencies, instead of just one as before.
Broadcom's two new chips share many core features, but not all. The BCM47722 is a chip that powers enterprise-class Wi-Fi access points and provides several features not included in the consumer-oriented BCM6765.
The enterprise-oriented BCM47722 not only supports Wi-Fi 7, but also supports many other networking protocols, including Bluetooth Low Energy, Thread, and Zigbee. Like Wi-Fi 7, these three protocols enable devices to transmit data wirelessly. But they use much less power, making them better suited for low-power connected devices like industrial sensors.
The BCM47722 is also forward compatible with upcoming Bluetooth channel detection technology, Broadcom said. As part of the Bluetooth wireless protocol, the latter technology will make it possible to determine the location of connected devices with high precision. It is designed for use cases such as tracking the location of fulfillment center warehouse robots.
The third chip that Broadcom introduced today is called the BCM4390 . It's not designed to power routers, but smartphones and tablets. Phone makers can use the chip to add Wi-Fi 7 support to their devices.
Broadcom said, BCM4390 also supports Zigbee and Threat low-power wireless network technology. In addition, it is compatible with both versions of the Bluetooth wireless protocol. The chip supports the standard version of the technology as well as Bluetooth Low Energy, a more power-efficient implementation optimized for tasks like syncing data between a user's phone and smartwatch.
In addition, Broadcom is a world-leading semiconductor company that provides products for wired communications, wireless communications, enterprise storage and industrial markets. The following are the 20 main chips and their functions commonly used by Broadcom in communication equipment.
