hField Technologies Wi-Fire Wi-Fi Adapter

We sometimes get so caught up in the excitement of the next big thing we throw the baby out with the bathwater. Based on the performance of the Wi-Fire Wi-Fi adapter, that might just be the case with IEEE 802.11g wireless routers.

If you value range over throughput, this is the Wi-Fi adapter for you. This ungainly device doesn’t rely on MIMO or IEEE 8011.n, it doesn’t even require a PCMCIA slot. When we plugged it into the notebook USB 2.0 port, it delivered unbelievable range with a year-old Asus WL700gE router equipped with a single antenna.

Indoors, the Wi-Fire performed no better than Linksys WPC600N adapter, and no 802.11g router can match the maximum throughput of an 802.11n model. But the Wi-Fire lived up to its name when it moved the notebook outdoors, delivering TCP throughput of 15Mb/s.

The speed constantly as when moved the notebook ever further away, 350 feet from the router, with the signal passing through an insulated, double thick interior wall and a steel garage door, the Wi-Fire delivered TCP throughput of 14.5Mb/s. Maximum range dropped to 135 feet on the other side of the house, but throughput remained steady at 13.2Mb/s.

The antenna is extremely directional, which wouldn’t be a problem if it weren’t mounted so loosely to its plastic stand. You can set it on a tabletop or clip it to your notebook screen, but after you’ve painstakingly located the reception sweet spot, the simple act of breathing is enough to move it out of position.
