IPQ4019, IPQ4029, IPQ4018 and IPQ4028 Different Wi-Fi standards - offering a choice of different performance levels

802.11ac and 802.11n are two different Wi-Fi standards that have some important differences in speed, frequency bands, antenna technology, and more. Here are the main differences:

Speed:
802.11n: This standard supports up to 600 Mbps (theoretical), but typically speeds range from 150 Mbps to 300 Mbps, depending on the device and environment.
802.11ac: The 802.11ac standard supports higher speeds, up to 1.3 Gbps (theoretical), with actual speeds typically ranging from 500 Mbps to 1 Gbps, depending on the device and environment.

Frequency band:
802.11n: Typically operates in two bands, 2.4 GHz and 5 GHz, but performs poorly in the 2.4 GHz band because it suffers from interference and congestion.
802.11ac: Mainly works in the 5 GHz band, which is relatively less crowded and provides higher performance and speed.

Antenna technology:
802.11n: Often uses multi-antenna technologies such as MIMO (multiple input multiple output) to improve signal coverage and performance.
802.11ac further improves MIMO technology and introduces more antennas, such as MU-MIMO (multi-user multiple input multiple output), to provide better multi-device support and performance.

Beamforming technology:
802.11n: Usually does not support beamforming technology, the signal transmission is more uniform.
802.11ac: Introduces beamforming technology that can adjust the direction of the signal to improve coverage and speed.

Number of devices connected simultaneously:
802.11n: Generally supports relatively few simultaneous connected devices.
802.11ac: Through MU-MIMO technology, it can support more simultaneous connected devices and provide better multi-device performance.
Overall, 802.11ac offers higher speeds, better coverage, less interference, and better multi-device performance than 802.11n.
There are many of these two types of WiFi chips on the market, but the performance and quality of chips from different suppliers are all differences, let's take a look at the well-known Qualcomm chips before the comparison difference:

IPQ4019, IPQ4029, IPQ4018, and IPQ4028 are a series of network processor chips from Qualcomm that are primarily used to build high-performance wireless routers, networking devices, and embedded systems. Here's a quick rundown of them:
