Wireless Network

Wireless Network, electronics

It refers to any type of computer network that uses wireless (usually, but not always radio waves) for network connections.

It is a method by which homes, telecommunications networks and enterprise (business) installations avoid the costly process of introducing cables into a building, or as a connection between various equipment locations. Wireless telecommunications networks are generally implemented and administered using radio communication. This implementation takes place at the physical level (layer) of the OSI model network structure.

Types of wireless networks:

Wireless personal area networks (WPANs) interconnect devices within a relatively small area, that is generally within a person's reach.

Wireless local area network (WLAN) links two or more devices over a short distance using a wireless distribution method, usually providing a connection through an access point for Internet access.

Wireless mesh network is a wireless network made up of radio nodes organized in a mesh topology. Each node forwards messages on behalf of the other nodes.

Wireless metropolitan area networks are a type of wireless network that connects several wireless LANs.

Wireless wide area networks are wireless networks that typically cover large areas, such as between neighboring towns and cities, or city and suburb. These networks can be used to connect branch offices of business or as a public internet access system. The wireless connections between access points are usually point to point microwave links using parabolic dishes on the 2.4 GHz band, rather than omnidirectional antennas used with smaller networks.

Cellular network or mobile network is a radio network distributed over land areas called cells, each served by at least one fixed-location transceiver, known as a cell site or base station. In a cellular network, each cell characteristically uses a different set of radio frequencies from all their immediate neighbouring cells to avoid any interference.

Samsung Breakthrough in Mobile Data Speed

5G, Samsung Electronics

Samsung Electronics reported that they made a breakthrough in mobile technologies, they said that they have increase the data transmission of the fifth-generation networks 100x than fourth-generation (4G) technology.

"Samsung's latest innovation is expected to invigorate research into 5G cellular communications across the world," said Samsung today. “The company believes it will trigger the creation of international alliances and the timely commercialization of related mobile broadband services.”

5G technology will allow users to transmit huge data files, like high-quality digital movies, “practically without limitation,” they said. With this technology, split seconds movie downloads will be a reality.

The European Union announced earlier this year a plan to invest €50 million, or $65 million, in research to deliver 5G mobile technology by 2020.

HTC One Mini

HTC One Mini
HTC has finally come up with a smartphone that can compete with other smartphone in the market today. The HTC One Mini has a impressive hardware and powerful software. At the launch of HTC One, people were impressed by the metal design, it looks durable and classy. The ultra-pixel camera was impressive. HTC One Mini or also known as M4 is the small version of HTC One just like the Samsung Galaxy S4 Mini. HTC One Mini is likely to be release in June.

The phone is similar to the HTC One, it has the same dual loudspeaker placement, volume buttons and MicroSD card slot. However, the M4 has a flash above it's camera unlike the HTC One

Since this is a small variant, I believe that the processor will be downgraded to dual-core insted of a quad-core. It would have a Ultrapixel camera, and expected to have a 1700 mAh battery.
