The Effects Of 4G
The Effects Of 4G:
The introduction of 4G will allow everyone to browse the internet of their mobile phones much faster and will diminish "Buffering." However, this was said about 3G when it came out and within quite a short period of time, the amount of time it took for the majority of the population to get it, it became very slow, hence the need for the move to 4G. So basically, 4G will be very good, but we will soon need "5G" or something else that will allow fast browsing.
4G has and will benefit companies and businesses also, because of the huge usage of emails etc that help businesses in contacting their partners and othe businesses.

Voice Over IP (VoIP)
-Voice over IP (VoIP, or voice over Internet
Protocol) commonly refers to the communication protocols, technologies,
methodologies, and transmission techniques involved in the delivery of voice
communications and multimedia sessions over Internet Protocol (IP) networks,
such as the Internet.
-Early providers of voice over IP services offered business models (and technical solutions) that mirrored the architecture of the legacy telephone network. Second generation providers, such as Skype have built closed networks for private user bases, offering the benefit of free calls and convenience, while denying their users the ability to call out to other networks. This has severely limited the ability of users to mix-and-match third-party hardware and software. Third generation providers, such as Google Talk have adopted the concept of Federated VoIP – which is a complete departure from the architecture of the legacy networks. These solutions typically allow arbitrary and dynamic interconnection between any two domains on the Internet whenever a user wishes to place a call.
-VoIP systems employ session control protocols to control the set-up and tear-down of calls as well as audio codecs which encode speech allowing transmission over an IP network as digital audio via an audio stream.
-VoIP is available on many smartphones and Internet devices so that users of portable devices that are not phones, may place calls or send SMS text messages over 3G or Wi-Fi.
