QCA9880 QCA9882 What’s the difference?|802.11ac Qualcomm Atheros Network card Wallys

The Qualcomm Atheros QCA9880 s a highly integrated wireless local area network (WLAN) system-on-chip (SoC) for 5 GHz 802.11ac or 2.4/5 GHz 802.11n WLAN applications. The QCA9880 integrates an on-board CPU for low-level setup of WLAN physical layer (PHY) and RF to offload the host processor for other tasks. It enables high-performance 3x3 MIMO with three spatial streams for wireless applications demanding the highest robust link quality and maximum throughput and range. The QCA9880 integrates a multi-protocol MAC, PHY, analog-to-digital/digital-to-analog converters (ADC/DAC), 3x3 MIMO radio transceivers, and PCI Express interface in an all-CMOS device for low power consumption and small form-factor applications.

The QCA9880 implements half-duplex OFDM, CCK, and DSSS PHY, supporting 1.3 GBps for 802.11ac 80 MHz channel operation. It supports 802.11n up to 216.7 Mbps for 20 MHz and 450 Mbps for 40 MHz channel operations, and IEEE 802.11a/b/g data rates. Additional features include Maximal Likelihood (ML) decoding, Low-Density Parity Check (LDPC), Maximal Ratio Combining (MRC), Space Time Block Code (STBC), and On-Chip One-Time Programmable (OTP) memory to eliminate the need for an external flash and to further reduce the external component count and BOM cost. The QCA9880 supports 802.11 wireless MAC protocol, 802.11i security, Rx/Tx filtering, error recovery, and 802.11e quality of service (QoS).

QCA9880 and QCA9882 are both Wi-Fi chipsets manufactured by Qualcomm Atheros. The main difference between the two lies in their capabilities and features. Here's a comparison:

1. Wi-Fi Standards: Both chipsets support the 802.11ac Wi-Fi standard.

2.Spatial Streams: The QCA9880 supports up to 3 spatial streams, while the QCA9882 supports up to 2 spatial streams. Spatial streams refer to the number of independent data streams that can be transmitted and received simultaneously, affecting overall data throughput.

3.Channel Width: Both chipsets support channel widths up to 80 MHz. Wider channel widths can provide higher data rates but may require more spectrum availability.

It's important to note that specific features and capabilities may vary depending on the implementation and firmware of the chipset. It's recommended to refer to the official documentation or datasheets provided by Qualcomm Atheros for more details.

Here is a comparison of the data rates and coverage for the DR900VX, DR600VX, and QCA9882 DR882 modules:

DR900VX:

Data Rates: Up to 1.3Gbps

Coverage: Reliable coverage with extended range and improved signal strength due to 3x3 MIMO technology and high output power.

DR600VX:

Data Rates: Up to 867Mbps

Coverage: Reliable coverage suitable for most standard-sized environments.

QCA9882 DR882:

Data Rates: Comparable to DR600VX (up to 867Mbps)

Coverage: Extended coverage and improved signal strength due to the high-power radio card.

Overall, the DR900VX offers the highest data rates, making it suitable for applications requiring fast and high-bandwidth connectivity. The DR600VX and QCA9882 DR882 modules offer slightly lower data rates but still provide reliable performance for most common wireless networking needs. The coverage of all three modules is generally satisfactory, with the DR900VX and DR882 offering extended coverage capabilities due to their specific features.
