Wi-Fi stands for wireless fidelity. Wi-Fi is the wireless network that used to connect the internet without wires. It’s based upon the radio technology. Many computers can be connected to each other through Wi-Fi and we can share files data and many of the other things through Wi-Fi. A Wi-Fi network operated just like a wired network, but without the restriction of wires, it not only enable user to share the data but it also provide easy connection to the internet and business network while travelling. It is the best wireless technology so far in the world. It is fairly easy to set up a Wi-Fi enable network at home or at office.

DISADVANTAGES OF THE Wi-Fi TECHNOLOGY

As we know the most beneficial technology has some of its disadvantage the same is for the Wi-Fi technology let us look some of the disadvantages of the Wi-Fi:-
1. The Wi-Fi band that is used in Wi-Fi is 2.4GHz does not required any license in most of the countries provide that it stay below the limit of

2. 100mW and one accept interference from other device; including interference which cause the user device to no longer function.

3. Power consumption in the Wi-Fi technology is quite high as compare to other device that led to use the excess battery and liberation of heat.

4. The Wi-Fi has unlicensed 2.4GHz spectrum which may cause degradation in performance because it often crowed with other device such as Bluetooth, microwave ovens, cordless phone etc.

5. Wi-Fi network also have a very limited range. A home Wi-Fi router might have a range of45m indoors and 90m outdoors.

6. The most common wireless encryption standard, WEP has been showed to be breakable even after correctly configured.

7. The Wi-Fi modem use dangerous electromagnetic radiation to send the signals to your computer through walls. This electromagnetic radiation can harm you and cause many of the

    I would say the average user does not take advantage of this feature in the first place, and as far as battery degradation goes, Samsung offers battery replacement for free (not including shipping) if your battery capacity falls under 80% within the first year which is a nice safety net to have. Although the Note5 sports a smaller battery than the Note 4, from my experience and many other user 's experiences the Note5 actually lasts longer! This is due to improvements in optimization and display efficiency. And just like the Note 4, the Note5 also charges very fast, in an hour I get about 80% charge from 0 meaning that most users should not have an issue with the battery…

    Many people are concerned about the dangers that cell phones pose, and they are told that keeping it a greater distance from their heads and using devices such as headphones can diminish much of the radiation; all of which is true. Unfortunately, since the technology industry has made the invention of wireless headphones, if people use their cell phones in conjunction with these devices, the radiation dosage can be even greater than normal. Using Bluetooth, the main type of wireless communication between devices, can have just as much electromagnetic radiation as talking on the phone. One team realized this and began to test the power density rating and the specific absorption rate (SAR), both of which measure radiation dosages. This team…
