Wi-fi is a wireless data networking protocol, which allows for PCs and laptops to access the internet, within a given area or "hotspot", via a high frequency wireless local area network (WLAN). The term Wi-Fi was coined by the Wireless Ethernet Compatibility Alliance (WECA) as another name for IEEE 802.11b networking standard. WECA is still involved in certifying new wireless modems in order to verify that they are fully compatible with the standard. |

   Wi-Fi vs. WiMax - Wi Do I Care?
Wi-Fi vs. WiMax - Wi Do I Care? Wi Fi Fo Fum, I think I smell the blood...oops wrong tale. This story doesn't involve giants, but it does involve giant leaps forward in technology that will affect us all. |

This story doesn't involve giants, but it does involve giant leaps forward in technology that will affect us all. Wi-Fi Hotspot Security You've set up your Boingo account, you're hanging out at the Home Turf sports bar in LAX and you figure you'll do a little business or check your e-mail while sipping a Chardonnay. Well, that's the point of all this; being able to take care of a few things while in a relaxing atmosphere. Free Wi-Fi Hotspots 'TANSTAAFL', the acronym for 'There Ain't No Such Thing As A Free Lunch', may be familiar to those of you who have taken a college economics class or two. Whenever you hear the word 'Free' in association with a product or service it's a good idea to keep it in mind because, in truth, nothing is free. Someone, somewhere, somehow, is bearing an economic cost; and so it is with free Wi-Fi hotspots. For the most part any of the free Wi-Fi hotspots you'll come across will have some sort of quid pro quo associated with them. 802.11 Topologies Excel in Higher Education Wi-Fi's real security risks and rumored performance lags seem to be small obstacles to its acceptance among institutions of higher education. With increasing frequency, extending the campus LAN means going wireless. The topologies are often similar from campus to campus, applying one and sometimes two of the IEEE's 802.11x wireless protocols. Most often, 802.11b is the standard selected, either as a precursor to the coming 802.11g (with which it is backward compatible) or because it is so broadly available, having been first on the market. But some campuses have also chosen 802.11a. |
