From the dictionary:   

n : a local area network that uses high frequency radio signals to transmit and receive data over   distances of a few hundred feet; uses ethernet protocol [syn: wireless local area network, area   network, WLAN, wireless fidelity, WiFi] <networking> Either of two different incompatible   radio-based LAN protocols, namely 802.11b (which speaks DSSS at 2.4GHz) and (which   speaks OFDM at 5GHz). The term was invented by the marketing departments of wi-fi   equipment manufacturers. It is, notionally, short for"wireless fidelity", on the analogy of hi-fi for   "highfidelity" audio.

Ok, So what the heck does that mean?

  It just means that if you have a wireless network card installed you can access the internet at   Shenandoah Valley KOA from your campsite, laundry or about anywhere else on SVKOA   property wireless internet cards can be bought for under $50 at any electronic store if you do not   already have one. They are very easily installed. Keep up with the eBay auctions, chat with friends   and loved ones, or just surf the web, free.

  Remember to pack your laptop on your next camping trip to SVKOA.
