IPQ5322 and IPQ5312 WiFi 7 Chipset Solutions Technical Analysis

Technical Analysis of Qualcomm IPQ5322 and IPQ5312 WiFi 7 Chipset Solutions 1. Background and Positioning

WiFi 7 (IEEE 802.11be), the evolution of WiFi 6/6E, is designed to deliver higher bandwidth, lower latency, and improved concurrency. Key enhancements include:

• 320 MHz channel bandwidth, doubling throughput compared to WiFi 6.

• MLO (Multi-Link Operation), enabling simultaneous transmission across multiple bands.

• 4096-QAM modulation, improving spectral efficiency.

• Enhanced OFDMA and MU-MIMO, supporting higher client density.

Against this backdrop, Qualcomm introduced the IPQ53xx series network processors, targeting mid-range to upper mid-range WiFi 7 applications. Within this series, IPQ5322 and IPQ5312 are two key models designed for different levels of routers, APs, and CPEs.
