A recent addition to the Wi-Fi standard is the Wi-Fi Protected Access solution (WPA).
Together, the physical and access control layers, along with extensions intended to implement extra features (such as WAP for security) make up the 802. (...)
Using Wi Fi on the road (09/02/2010)
(...) So let's try to build out a public infrastructure so that everyone can use Wi-Fi and charge whatever the market will bear.
The capitalistic, entrepreneurial side of Wi-Fi is what you may meet when you access the Internet via Wi-Fi in public venues such as Starbucks, Borders, hotels, and airports. There will be no free lunches in these venues! On the other hand, some businesses have found that offering free Wi-Fi is a great way to entice customers to stick around for a while and spend more money. (...)

Close review of what is GSM (08/09/2010)
(...) It is said to be as Dual SIM till it can hold and read 2 SIM's whether it would be a dual SIM TV phone or anything like that. If a cell phone supports two SIM's, it doesn't mean that both of them will be active at the same time! You would need a dual standby function in order to make this possible. Most of us must be thinking that a Dual SIM is useless as it is not able to support both SIM's in a single interval of time, but this is not strictly true as only the dual SIM function can: * Help to keep your personal and business contacts separate from each other as well as keeping them in the same place.

Being able to properly integrate information from the two types of network connections can be tricky, yet many software packages allow you to integrate these into one, especially those that are network performance management applications. NPMs are generally pretty flexible systems that allow you to configure them as a networking engineer might require them, and wireless networking is no different.
There’s really no reason to separate this data. (...)
Ultraviolet Radiation (06/24/2010)
(...)
Unlike x-rays, however, ultraviolet is not penetrating. The thick atmospheric blanket of ozone stops them well; a thick blanket of cotton, or even a thin shirt, does quite a good job. Consequently, the effects of ultraviolet on the human body are limited to the places that sunlight can reach-the skin and the eyes. (...)
Microwave Radiation (06/24/2010)
(...) Consequently, organs inside a body can be heated (potentially killed) by microwave beams. The thermal energy of microwaves is also known to cause cataracts.
Wavelengths longer than microwaves (those typical of VHF television, FM, and standard broadcast radio signals) also cause thermal effects by transferring energy to materials, but they are not as reactive with biological tissue. (...)
Low Frequency Radiation (06/24/2010)

In the laboratory, the potential biological effects of ELF at levels below those which would cause the heating of tissue have been extensively investigated for about the last decade. The results of that research are beginning to show that far from being innocuous and non-interactive with biological tissue, ELF electrical and magnetic fields can be subtly active with both beneficial and harmful effects. On the positive side, ELF fields are used in treating bone fractures. (...)
