CSW2201
CSW2201-23L LR-WiFi Module
CSW2201-23L uses a USB 2.0 Device interface to add long-range video, control and telemetry to existing Linux equipment without redesigning an SDIO interface. It supports IEEE 802.11b/g/n, private LR-WiFi and dual-stream 802.11n MIMO. Applicable drivers and matching endpoints/antennas are required; it is not a long-range hotspot for direct phone Wi-Fi access.
Key specifications
- Wireless protocols
- IEEE 802.11b/g/n; private LR-WiFi
- Host interface
- USB 2.0 Device; applicable host driver required
- Band variants
- The 23L overview lists 2.3–2.3835 GHz while another table lists 2.4 GHz; confirm SKU, band and compliance with the controlled project document
- Nominal PHY rate
- 802.11n HT20 up to 144.4 Mbps / HT40 up to 300 Mbps; not LR-WiFi application throughput
- Supply
- 3.3 V ± 0.2 V; datasheet maximum current 600 mA, subject to hardware confirmation
- RF reference
- RX sensitivity down to -94 dBm; TX approximately 17.5 dBm, subject to mode and regional limits
- Dimensions
- 12.9 × 12.2 × 1.75 mm; datasheet tolerance ±0.2 mm
- Topology
- AP / STA; Mesh requires matching firmware and project configuration
- Historical test reference
- A historical 2.4 GHz CSW2201 test recorded UDP throughput of 12.6 / 8.78 Mbps at 900 / 1000 m; not a guarantee for the 23L variant
- Test conditions
- Static open line of sight, 2427 MHz, 2.5 dB antenna gain, antenna heights 2 / 1.5 m, 600-second iperf UDP test; results vary by environment
