Wireless internet connectivity (wi-fi or WiFi) has become a standard feature on smartphones. Being able to set your smartphone up as a wireless hotspot is almost also becoming commonplace.
Keeping your hotspot secure is important, so that only authorised persons can use it. There are two broad encryption protocols: WEP and WPA. Both require a password, but are there any differences between the two? Yes; there are.
WEP (wired equivalent privacy) is the older and less secured option. WPA (wi-fi protected access) is newer and more secure. In other words, WPA is better than WEP. WPA2 is built on WPA and is even more secure.
Both protocols are not compatible, so pay attention when getting and connecting your devices.
Setting up a hotspot on BlackBerry OS7 devices is strictly based on WPA2. On Android 4.0 devices, options for WEP, WPA, and WPA2 are there, so you can make a choice. On the Nokia N9, the JoikuSpot-based hotspot supports WEP only.
I am not sure that many people bother about these details, but for those of you who are interested, now you know. Cheers!
