Description
Laptops are the historical CSI experimental host: Intel-equipped ThinkPads / Dells from the early 2010s ship the intel-5300 in their mini-PCIe slot, which is exactly the hardware Halperin's CSI Tool needs. Most legacy CSI datasets were collected with a laptop running Linux + the patched iwlwifi driver acting as the receiver (monitor mode) while another laptop or AP transmitted. Modern usage is rarer — Raspberry Pi + Nexmon is cheaper and more deployable — but laptops remain the common platform for ad-hoc CSI experiments where a researcher walks around with a receiver.
Specs / capabilities
- Mini-PCIe / M.2 slots fit Intel 5300, Atheros AR9xxx, and modern Intel AX200/AX210 NICs
- Linux distros run the Halperin / Atheros / PicoScenes toolchains directly
- Battery-powered → mobile receiver
- USB ports for external SDR / paired sensors
Quirks / known issues
- Vendor BIOS whitelist may reject swapped Wi-Fi cards (older ThinkPads)
- Suspend / resume often breaks CSI capture sessions
- Modern (post-2018) laptops increasingly solder Wi-Fi modules → no swap-in CSI NIC
Used by (papers)
- Pre-2019 CSI papers using ThinkPad / Dell laptops as Tx/Rx hosts
