What Is Wireless?
Wireless
The word wireless is dictionary defined as "having no wires". In networking terminology, wireless is the term used to describe any computer network where there is no physical wired connection between sender and receiver, but rather the network is connected by radio waves and/or microwaves to maintain communications. Wireless networking utilizes specific equipment such as NICs, APs and routers in place of wires (copper or optical fiber) for connectivity.
What Is WLAN?
WLAN
Acronym for wireless local-area network. Also referred to as LAWN. A type of local-area network that uses high-frequency radio waves rather than wires to communicate between nodes.
What Is Wi-Fi?
Wi-Fi
Wi-Fi is the name of a popular wireless networking technology that uses radio waves to provide wireless high-speed Internet and network connections. A common misconception is that the term Wi-Fi is short for "wireless fidelity," however this is not the case. Wi-Fi is simply a trademarked term meaning IEEE 802.11x.
The Wi-Fi Alliance, the organization that owns the Wi-Fi (registered trademark) term specifically defines Wi-Fi as any "wireless local area network (WLAN) products that are based on the Institute of Electrical and Electronics Engineers' (IEEE) 802.11 standards."
Initially, Wi-Fi was used in place of only the 2.4GHz 802.11b standard, however the Wi-Fi Alliance has expanded the generic use of the Wi-Fi term to include any type of network or WLAN product based on any of the 802.11 standards, including 802.11b, 802.11a, dual-band, and so on, in an attempt to stop confusion about wireless LAN interoperability.
How Wi-Fi Works
Wi-Fi works with no physical wired connection between sender and receiver by using radio frequency (RF) technology, a frequency within the electromagnetic spectrum associated with radio wave propagation. When an RF current is supplied to an antenna, an electromagnetic field is created that then is able to propagate through space. The cornerstone of any wireless network is an access point (AP). The primary job of an access point is to broadcast a wireless signal that computers can detect and "tune" into. In order to connect to an access point and join a wireless network, computers and devices must be equipped with wireless network adapters.
Wi-Fi Support
Wi-Fi is supported by many applications and devices including video game consoles, home networks, PDAs, mobile phones, major operating systems, and other types of consumer electronics. Any products that are tested and approved as "Wi-Fi Certified" (a registered trademark) by the Wi-Fi Alliance are certified as interoperable with each other, even if they are from different manufacturers. For example, a user with a Wi-Fi Certified product can use any brand of access point with any other brand of client hardware that also is also "Wi-Fi Certified". Products that pass this certification are required to carry an identifying seal on their packaging that states "Wi-Fi Certified" and indicates the radio frequency band used (2.5GHz for 802.11b, 802.11g, or 802.11n, and 5GHz for 802.11a).
Wi-Fi Alliance
An organization made up of leading wireless equipment and software providers with the missions of certifying all 802.11-based products for interoperability and promoting the term Wi-Fi as the global brand name across all markets for any 802.11-based wireless LAN products.
While all 802.11a/b/g products are called Wi-Fi, only products that have passed the Wi-Fi Alliance testing are allowed to refer to their products as "Wi-Fi Certified" (a registered trademark). Products that pass are required to carry an identifying seal on their packaging that states "Wi-Fi Certified" and indicates the radio frequency band used (2.5GHz for 802.11b or 11g, 5GHz for 802.11a)
This group was formerly known as the Wireless Ethernet Compatibility Alliance (WECA) but changed its name in October 2002 to better reflect the Wi-Fi brand it wants to build.

WiFi Internet Sharing via WiFi Notes:
If hotel rooms are supposed to become my home away from home then there is one thing that I absolutely hate: the unfriendly wifi.
1. I dislike paying extra for wifi
2. I dislike having to log on with superlong codes each time I need to use wifi
3. I dislike having to buy wifi for each of my devices separately!
The first two are unfortunately not going to go away until hotels come to their senses but the third can be resolved by without relying on the hotels.
This is a guide to creating your own wifi in a room where the only Internet connection is wifi (i.e. no Ethernet). You will need laptop, wireless router, Ethernet cable. I have done this with my Apple equipment. I am sure you can do this in other connections but I have not tried it. I have not done this all too often and remembering these settings are the reason I wrote this guide.
Begin by Logging into the wifi with your laptop.
Go to sharing (Settings->sharing->Internet Sharing) Select from wifi share via Ethernet and turn it on. When troubleshooting turning sharing on/off again has sometimes resolved the problem.
Connect your Wireless router to the computer. I use the new small Airport Express its lightweight for travel. Connect you Ethernet cable from the laptop to the Ethernet WAN port.

Go to the Airport Utility (Applications -> Utilities -> Airport Utility)
Base Station: pick a name and password for the base station. This is not the wifi net or password but the way to log into the base station to make changes if need be.
Network: You are creating a wireless network. Pick name for that wifi and password. Chose Bridge mode.
Note some situations may not like you doing all this so picking a wifi name that screams out whom you are may be unwise. Obviously be wise about passwords as well.
Internet Connection: This is the hotel wifi that you logged into in the beginning of this guide.
The update and you are away. You should now log all your devices onto the wifi you have created and they are all sharing the internet connection that you are paying for.
