Still, 3G is drifting and it has empowered the broadband web on expensive sales in the greater part of the advanced cells utilized today with all such offices like surfing, checking messages, watch recordings etc. There comes 4G which has guaranteed with various noteworthy advantages and innovation far higher than the 3G. It’s been being developed for a couple of years from now and it is at last prepared to cut its dispatch on an expansive scale.

 

4G-The Latest Technology

4G-The Latest Technology

Points of interest:

The principle favorable position of 4G innovation is the much quicker information transmission rates. The 4G spaces are required to be ten circumstances more prominent than the 3G, with “ultra-broadband” office. With a much higher exchange rates the clients of cell phones will have results. A few exercises with overwhelming information utilization, for example, gushing video or music will stack at much quicker rates with less buffering time. It empowers high determination and brilliant video and sound inside satisfactory load times.

It has monstrous ramifications of advanced communications. The video calling from telephones and tablets are a great deal more reasonable progressing because of the expanded data transfer capacity, without the need of the Wi-Fi extends.

Organize Coverage of 4G:

For utilizing 4G, clients must be inside the 4G scope zone. The created nation like the United States and the United Kingdom gets the genuinely wide scope. While other created nations are anticipating 66% by mid-2013. For the most part, real metropolitan urban communities in USA and Europe are sitting tight for the entry of 4G administrations. Littler towns and some rustic territories may need to sit tight for a more extended time.

Will a WiFi Repeater be Solution for our Problems??

A WiFi repeater or extender is used to extend the coverage area of your WiFi network. It works by receiving your existing WiFi signal, amplifying it and then transmitting the boosted signal. With a WiFi repeater you can effectively double the coverage area of your WiFi network – reaching far corners of your home or office, different floors, or even extend coverage to your yard.
WiFi boosters, repeaters, and extenders are mostly the same thing – basically the devices to improve WiFi coverage. There isn’t a clearly defined difference between devices that manufacturers describe as “repeaters” and devices described as “extenders”. However, not all WiFi extenders work in the exact same way. There are several different kinds of devices available and below we aim to explain what those differences are and how they work, so that you can choose the best WiFi repeater for your circumstances.
One of the best options for a new router is the Archer C9 AC1900 Router from TP-LINK which offers 802.11ac, the next generation of WiFi. It’s a dual band router with ultrafast dual core processors and four gigabit ethernet ports for use with Smart TVs or game consoles. It comes with unique Beam forming technology. This technology allows the routers to concentrate the WiFi signal towards your WiFi devices. By targeting the WiFi signal to where it’s being used, the speed and performance of your network is greatly increased.
WiFi Repeater effectively contains two wireless routers, similar to the wireless router you already have in your home or office. One of these wireless routers picks up the existing WiFi network. It then transfers the signal to the other wireless router, which transmits the boosted signal.

WiFi Repeaters are very easy to install. All you have to do is place the repeater in a location that can receive your existing WiFi network, and then attach the power supply. You can then log into the WiFi repeater via your computer, and input the login details and password of your existing WiFi network, to allow the WiFi repeater to connect and extend.
A major advantage of this repeater being it creates a second network. If your first network is not available, your device will connect to the second. But in some parts of your house, your device will be able to detect both networks at the same time. This means that if you wish to change from the original network to the boosted network you will have to disconnect and then reconnect.
All WiFi repeaters have some speed loss, but some are much worse than others. WiFi repeaters work by receiving wireless signal and rebroadcasting it, but single band repeaters have to receive, then retransmit each packet of data using the same radio on the same channel. This can cost single band repeaters 50% of their bandwidth.
One final feature that helps reduce speed loss is dual radios. If the device has dual radios, it can speak to the main router on lower channels, and then rebroadcast on higher channels. The Hawking Smart Wifi Repeater Pro (HAW2R1) uses two Wi-Fi radios. One Wi-Fi radio receives the signal and the other radio rebroadcasts the boosted signal. This clever design allows the boosted signal to utilize a different WiFi channel, which greatly increases performance compared to single radio repeaters. The Smart Repeater Pro also has a very powerful high gain antenna that can pick up even very weak WiFi signals, and it rebroadcasts that signal on two powerful 3dBi omni-directional antennas.

Now Say Bye to Disturbed WiFi!!

An amazing and fantastic solution to relentless wifi addiction is finally been discovered. You can buy a wifi range extender for your laptop, like the TP-Link N300 Wifi Antenna. This ingenious little piece of computer equipment like really rocks. It increases the laptop’s WiFi signal strength 3 to 5 times. With this anyone will be able to locate many more open wireless networks than with computer’s internal wireless card. A folding directional antenna helps pick up the best signal and maximizes my chances for connecting to the internet in remote locations.

There are 2 primary situations when having a wifi antenna helps greatly. The first is when an individual staying at a hotel, guesthouse, or hostel and the wifi signal doesn’t reach my room.
Maybe there’s only one router, and it’s in a public area. Connecting the external wifi antenna allows only to work from the comfort of the room with a powerful signal. The range seems to be a few hundred yards depending on how many walls/buildings are in between.
The other situation is when one finds the perfect cafe to work at (ambience, coffee, prices, food, comfort), but their wifi connection sucks. However maybe there is a cafe down the street with a much better connection. Using my wifi antenna, one can connect to the 2nd cafe’s fast wifi, while working from the cafe he/she actually prefers.
It may not seem like much, but finding a decent workspace with good wifi is very important for my productivity when working on the road.
WiFi Antenna Booster
The extended range of this external wifi card has saved my ass on quite a few occasions while traveling. Because the boosted wifi signal is so much stronger, I’m frequently using it even when my internal card sees some of the same connections.
A 20% network signal suddenly becomes a 99% signal after hooking up my TP-Link wifi antenna.
Wi-Fi is a technology for WLAN based on the IEEE 802.11 (a,b,g) specifications. Wireless fidelity is a popular technology that exchanges data’s through wireless networks with access point. An access point is similar to a network HUB transmitting data’s between connected wireless devices and a connected wired device, like an Ethernet hub or switch. The distance covered by of one or more inter-connected access point (hotspots) can extend from an area of few meters to as large as many kilometers. Coverage in the larger area may require a group of access points with overlapping coverage. An access point (AP) broadcasts its SSID (Service Set Identifier, “Network name”) through packets broadcasted every 100 ms at 1 Mbit/s.
The wireless network is formed by connecting all wireless clients to the access point (AP). Access points are important for providing heightened wireless security and for extending the physical range of service a wireless user can access by using WEP and WAP. The range of the WI-FI can be increased by re positioning the router or access point (AP) to avoid obstructions and radio interference. The range can also be increased by adding another access point (or router).Ad hoc does not use any intermediary device such as Access Point. Infra Structure and Extended modes use Access Point as interface between wireless clients. WI-FI signal boosters are WI-FI amplifiers that are attached to access point or routers. This booster boosts the signal strength to 600%. The need for reliability, uninterrupted and seamless communication is one of the top priorities of every house. Repeaters should be used for better performance and high resolution. Repeaters are the networking devices that help to repeat the signal or increase the reach of existing wireless network; this can be used in remote place where signal strength is too low and unreachable.
DEMERITS OF EXISTING SYSTEM
In the existing system, Omni-directional antennas can be used in access point to access internet. Omni directional antenna can be accessible in all directions of 360 degrees. It is as well called the “non-directional” antenna because it does not favour any particular direction. Omni directional antenna provides access range up to 100-300 feet indoor and 500 feet outdoor. Antennas are electrical conductors that radiate electromagnetic energy into space. By using Omni directional antenna coverage area become smaller as it can be accessible in all directions.

How Harmful is the Radiation from Cell Phones?

The radiation from cell phones is so scary that can enter all the way into their midbrain, where tumours are more deadly. Sadly, children and teens are at greatest risk—both for parotid gland tumours and brain tumours—as their thinner skull bones allow for greater penetration of cell phone radiation. In addition, children’s cells reproduce more quickly, so they’re more susceptible to aggressive cell growth. Children also face a far greater lifetime exposure. According to experts, those who begin using cell phones heavily as teenagers have 4 to 5 times more brain cancer as young adults!

Pregnant women would also be wise to avoid cell phones as much as possible. In 2008, researchers analyzed data from nearly 13,000 children and found that exposure to cell phones while in the womb, and also during childhood, were linked to behavioral difficulties. Using handsets just two or three times a day during pregnancy was enough to raise the risk of their babies developing hyperactivity and difficulties with conduct, emotions, and relationships by the time they reached school age—and the risk became even greater if the children also used the phones themselves before the age of seven.
Overall, the study revealed that mothers who used mobile phones were 54 percent more likely to have children with behavioral problems. Later on, when the children began using cell phones themselves, they were:
80 percent more likely to suffer from behavioral difficulties
25 percent more at risk from emotional problems
34 percent more likely to suffer from difficulties relating to their peers
35 percent more likely to be hyperactive
49 percent more prone to problems with conduct
It’s important to realize and note that as long as your cell phone is on, it emits radiation intermittently, even when you are not actually making a call. So wearing a cell phone on your hip for 15 hours a day is giving that area of your body nearly continuous radiation exposure.
Previous studies have found that cell phone radiation can affect men’s sperm count, and the quality and motility of their sperm, and this may be a far greater issue than its effect on bone density.
Men in particular may want to reconsider carrying their cell phones on their belts or in their pocket, in close proximity of their reproductive organs. In addition, you have a number of other sensitive organs in that general area, including liver, kidneys, colon and bladder—all of which are susceptible to radiation.
