HP Trembler Half Mini Card 802.11 module
This HP 588551-001 Trembler Half Mini Card provides 802.11B/G/N wireless connectivity in a compact form factor. It suits laptops or embedded systems that accept a half-mini card slot. The module supports a 1x1 antenna configuration for basic wireless networking needs.
Practical limits of 802.11B/G/N 1x1
The 1x1 antenna design restricts throughput to a single spatial stream, limiting maximum link rates compared to multi-stream devices. Older 802.11B and G rates reduce efficiency on modern networks. This card will not meet the needs of buyers who require higher bandwidth or multi-stream performance.
