All three devices include what Linksys dubbed "SpeedBooster," technology built on Broadcom Corp.'s Afterburner, to increase wireless data-transmission speeds and throughput.
SpeedBooster-equipped products will deliver the faster speeds, said Linksys, a division of router and switch maker Cisco Systems, while its backward-compatible support for traditional 802.11b/g gear--including equipment made by other manufacturers--will automatically downshift the hardware to match slower speeds.
The trio also sports new support for additional security protocols, including Wi-Fi Protected Access and IEEE 802.1x.
The SpeedBooster line will be available in late April, with prices of $129.99 for the router and $99.99 for the notebook and PCI adapters.
