5G netwerk in ontwikkeling

Vergeet het 4G netwerk. Zuid-Korea is de eerste die een 5G netwerk ontwikkeld, Japan, China, de VS en Europa volgen.

Bedrijven zoals Samsung en Huawei zijn druk bezig met de ontwikkeling van 5G technologie die overal ter wereld zal kunnen worden gebruikt.

Voorlopig wordt de 5de generatie draadloze netwerken erkend als Tactile Internet, 5th generation mobile networks of 5th generation wireless systems.

De snelheid zal fenomenaal zijn. Terwijl het 4G netwerk een maximum haalt van 100 Megabits per seconde (12,5 Megabyte) zal het 5G netwerk een snelheid van 10 Gigabits per seconde (1,25 Gigabyte) bereiken. Dat is 100 keer rapper dan het 4G netwerk.

Een film van ongeveer 1 GB zal in een kleine seconde kunnen gedownload worden op uw Smartphone of computer.

Het kan nog sneller
Britse wetenschappers van de Surrey universiteit zijn erin geslaagd om een recordsnelheid te bevestigen over een 5G netwerk van honderd meter. Hierbij behaalden ze een snelheid van maar liefst 1 Terabit per seconde, dit is maar liefst 65.000 keer sneller dan een 3G netwerk.

Toekomst
Het is nog even wachten tot we zulke snelheden zullen ervaren met onze Smartphones en computers.
Volgens een Zuid-Koreaans IT bedrijf zal het 5G netwerk er rond 2020 al kunnen zijn. Maar laten we eerst eens het 4G netwerk overal toepassen voor we 5G gaan gebruiken.

5G network under development

Forget the 4G network. South-Korea is the first to develop a 5G network, Japan, China, the US and Europe follows.

Company's like Samsung and Huawei are bussy to developing 5G Wireless Technologies that can be used all over the world.

For now, the 5de generation mobile networks are called Tactile Internet, the 5th generation mobile networks or the 5th generation wireless systems.

The speed would be phenomenal. While a 4G network can reach a speed from 100 Megabits per second (12,5 Megabyte), the 5G network can reach a speed of 10 Gigabits per second (1,25 Gigabyte). That's about 100 times faster than the 4G network.

A movie from about 1 GB will be downloaded in seconds to your Smartphone or computer.

It may even go faster
British scientists of the Surrey University have reached a record speed on a 5G network of hundred meters. They achieved a speed up to 1 Terabit per second, this is 65,000 times faster than a 3G network.

Future
It's will get som time until we experience such speeds with our smartphones and computers.
According to a South Korean IT company, 5G network will be available in 2020. But first let's use the 4G network before we apply the 5G network.

Network cable speed recognition and what type of network cable do you need in which case

There are plenty of networking opportunities and network cables available. But there are so many types of network cables that it's difficult to know witch type of network cable you exactly need.

Witch network cable do I need?
If you want to work with Cat5e and Cat6 than you need a 1000 Mbps network switch (Ethernet Switch) for a remarkable improvement in the throughput of the data. Several network cables with category Cat5 connection to a 1000 Mbit switch goes also. For example, with 10 PCs connected to a network with Cat5 network cables you can get maximum speed of 100 Mbits 1 computer can still reach there maxiumum speed of the 1000 Mbit swich.

A 1 GB network that does not mean there goes 1GB over the cable, but the data goes in pairs added together,250 MB in 1 pair.

Types of data speeds of network cable
Cat4 10 MBit = 1,25 MByte

Cat5 100 MBit = 12,5 MByte

Cat5e 150 MBit = 18,75 MByte

Cat6 250 MBit = 31,25 Mbyte

On this site you can calculate from Megabytes to MBits and vise versa:

Specifications of network cables
UTP: Unshielded Twisted Pair, the normal network cables.
STP: Shielded Twisted Pair, network cables for in noisy environment.

With Cat5 you have UTP and FTP cables. If you aren't routing the cable along power cables, transformers, fluorescent fixture, etc. than you can use UTP cable. Otherwise you have FTP and FTP cable connectors. In FTP, the equipment must also support FTP. In FTP, the wires and the cable is shielded. The veins of Cat6 cables are always shielded. Cat6 cables are much more expensive. In CAT4 you often see that there are only 2 pairs, 4 threads can be used. Cat4 2 pairs are also used for the transmission of the signals. Cat5 also send the data in 2 pairs. In Cat5e all 4 pairs are used.

Conditions for network cabling 
The cable can't be longer than 7 meters from the connection to the computer..
The (thicker) network cable between the 2 connection boxes is allowed up to maximum 100 meters.

What are Cross linked network cables?
Cross linked cables are used to connect 2 computers with each other without using a hub or router to connect with. These network cables are not suitable for network connections.

This applies to all types of straight network cables. Whether it's CAT4, 5, 5e or 6. Doesn't matter if it are UTP or STP cables. Cross-link cables are in most cases not work unless you have a special NIC that can switch itself (as in certain IBM notebooks). From Cat5 you can not extend the cables with coupling connectors to use patch cables.

The future: Cat7

There is a Cat7 network cable in development.

These cables would theoretically transfer data of 10GB.
These aren't yet fully developed so fiber optic cables are currently the only good solution for such data rates.

How to make a VPN connection in Windows 7

You want to connect to the files on the server of your work but are at home or somewhere else? Well below you can find how to make a secure connection to your corporate network over the Internet.

1. Click the Start button of Windows 7.
