Compex WiFi 7 Dual Band Dual Concurrent Modules

Compex Systems (Compex) is set to take wireless connectivity to the next level with the latest expansion of its popular dual-band Wi-Fi 7 module lineup. Introducing the new M.2 variants, including WLTB7002E25 with an M.2 B+M Key and the WLTE7002E25 with an M.2 E Key, these additions complement the Compex’s existing WLE7002E25, which features the popular standard mini PCIe form factor. Together, these Wi-Fi 7 modules offer comprehensive solutions with enhanced performance, flexibility, and compatibility — all at competitive Wi-Fi 6 prices. Powered by Qualcomm’s QCN6224, QCN6274 and QCN9274 Waikiki series radio chipsets, the WLE/WLTE/WLTB7002E25 are dual-band concurrent 2.4+5GHz Wi-Fi 7 (802.11be) modules, offering wider signal coverage by transmitting both bands concurrently, reducing latency with Multi-Link Operation (MLO) support, featuring OFDMA and 4096 QAMs. Delivering up to 20dBm per chain, these 2×2 MU-MIMO models are ideal for enterprise, industrial, cybersecurity, transportation, and SMB applications. “Our expanded Wi-Fi 7 module lineup […]

WiFi 7 access point and client M.2 modules are cheaper than I thought

WiFi 7 M.2 modules

We have already seen WiFi 7 mini PCIe and M.2 modules from Compex for business customers, but I’ve recently noticed AsiaRF AW7991-AE2 M.2 module rated BE5000 offers an affordable alternative design for access points for just $58 plus shipping. But adding WiFi 7 to a consumer device can be cheaper than I expected as Intel BE200 or MediaTek MT7925-based M.2 modules can be purchased for around $20 to $30. Let’s have a look at some of the options available. AsiaRF AW7991-AE2 dual-band WiFi 7 “access point” M.2 module AsiaRF AW7991-AE2 specifications: SoC – MediaTek MT7991AV (Filogic 660?) with 32bit RISC-V MCU for Wi-Fi protocol and Wi-Fi offload Chipset – MT7976C WiFI 6 3×3 MIMO chipset System Memory –  8MB WLAN IEEE 802.11a/b/g/n/ac/ax/be compliant Frequency bands 2.4GHz – Bandwidth: 20/40MHz; 2T2R 2ss 5GHz – Bandwidth:20/40/80/160MHz; T3R 3ss Dual-Band Dual Concurrent (DBDC) Supports up to 4096-QAM Data rate of up to 688Mbps […]

GEEKOM GT1 Mega review with Ubuntu 24.10 – Part 3: Linux on an Intel Core Ultra 9 185H “Meteor Lake” mini PC

GEEKOM GT1 Mega Ubuntu 24.10 Linux review

We’ve already had a look at GEEKOM GT1 Mega’s hardware with an unboxing and a teardown before following up with a thorough review of the Intel Core 9 Ultra 185H mini PC with Windows 11 Pro. After being interrupted by some Raspberry Pi reviews, I finally had the time to test the GEEKOM GT1 Mega with Ubuntu 24.10 to check out how well (or not) it works with a recent Linux distribution. I’ve tested the features of the Meteor Lake mini PC in Linux, ran some benchmarks, evaluated storage and network performance, played 4K and 8K videos on YouTube at various frame rates, went through a stress test to check its thermal design, and finally measured the mini PC’s fan noise and power consumption. Ubuntu 24.10 installation I would usually review mini PCs with the latest Ubuntu LTS version which would currently be Ubuntu 24.04.1. However, since the Intel Core […]

Wi-Fi 8 (802.11bn) to focus on reliability and efficiency while maintaining Wi-Fi 7 performance

WiFi 4 vs WiFi 5 vs WiFi 6 vs WiFi 7 vs WiFi 8

Wi-Fi 7 (802.11be) routers and modules have only been launched recently, but engineers are already working on Wi-Fi 8 (802.11bn) “Ultra High Reliability (UHR)”, and MediaTek shared some details in a whitepaper detailing some of the improvements of the new standard for its upcoming Filogic Wi-Fi 8 SoCs. Surprisingly, there aren’t any enhancements to the maximum performance with Wi-Fi 8 still offering up to 320 MHz channel bandwidth, 23 Gbps maximum PHY rate, and support for 2.4 GHz, 5GHz, and 6GHz frequency bands, as well as up to 8 spatial streams. The Wi-Fi 8 improvements are all meant to improve Wi-Fi reliability, network efficiency, and power consumption in IoT use cases, which will end up improving the overall WLAN performance when many nodes are connected. Wi-Fi 8 new features: Coordinated Target Wait Time (TWT) allows low-power IoT devices to negotiate specific times for transmission with access points in order to […]
