"Wi-Fi 8 introduces a technology known as Seamless Multi-Link Device (SMD) to address this issue. Instead of first disconnecting from the existing connection and then establishing a new one, a device with SMD first connects to the next access point before releasing the old connection. According to Broadcom, this approach results in approximately 25 percent less packet loss and a similar reduction in latency."
"The BCM4918 acts as the main processor for Wi-Fi 8 access points. It is a system-on-a-chip with a quad-core ARMv8 CPU and the Broadcom Neural Engine for AI and machine learning applications. This combination makes it possible to run AI models locally on the access point, for example for network monitoring and automatic resolution of connection problems. The chip is also equipped with specialized networking engines and a Dual Issue Runner Packet Processor, which can process data packets without CPU intervention."
Broadcom introduced a new Wi‑Fi 8 platform comprised of the BCM4918 network processor and radio chips BCM6714 and BCM6719 for premium access points. Wi‑Fi 8 shifts emphasis from peak throughput to stable, low‑latency connections for environments vulnerable to interruptions, such as industrial wireless communications. Seamless Multi‑Link Device (SMD) roaming lets a device connect to the next access point before releasing the current one, cutting packet loss and latency by roughly 25 percent. The BCM4918 combines a quad‑core ARMv8 CPU, Broadcom Neural Engine for local AI, specialized networking engines, and a packet processor to maintain high throughput and low latency. The platform includes hardware support for cryptographic protocols to enhance security.
