What’s the Difference Between WiFi 2,4 GHz and 5 GHz?

  • by

Some of the most recent wireless routers and WiFi modem-routers are dualband, that is they let you set up two wireless independent networks that work on completely different frequency spectrums. The two WiFi networks, 2,4 GHz and 5 GHz, can generally work at the same time, so much so that each one have a different SSID with which it appears on mobile nearby devices.

Acronym for Service Set Identifier, the SSID is the name with which a WiFi network appears to its users. By doing a scan through a software like inSSIDer or even air-cracking, you’ll get the list of the SSIDs corresponding to the wireless networks available nearby, along with their features. By default, many routers use the name and the model of the device itself as SSID: it’s highly suggested to change it, even if it’s actually superfluous to block its spread across the ether (broadcasting) because the SSID of an hidden network could be found in a pretty simple way.

But what’s the difference between WiFi 2,4 GHz and 5 GHz?

The introduction of the 5 GHz band solves, firstly, the problem about the crowded wifi networks. In densely populous areas, apartment buildings, in areas with large presence of offices and commercial activities is actually something common, to find lots of WiFi networks, especially if you consider both the ones that reveal their SSID and the ones that hide it.

Top 10 most attractive ultrabooks on the market

  • by

Ultrabooks are one of the most attractive categories of personal computers and next to the 2-in-1 laptops and gaming dedicated computers, they are the ones pushing a market that’s been going downward in recent years. Ultrabooks stand out for their focus on mobility, with thin and light designs; some in convertible formats; use of premium chassis materials such as aluminum, magnesium or carbon fiber; great battery life; HD displays with sizes between 12 and 14 inches; SSDs for storage and sufficient processing and graphics card power. Today we dedicate our article to the most interesting models for sale and -thanks to the presentations at IFA 2016- others that will arrive starting this month. Attractive but not cheap, they require a minimum investment that stands at the barrier of 1,000 dollars and upward. (The numerical position is random and does not respond to any selection criteria)

Nvidia GTX 1060 vs GTX 960 vs GTX 970 vs GTX 980 vs GTX 1070 vs AMD RX 480 vs R9 390: Specs and Benchmark Comparison, which model should I choose?

  • by

Just a few weeks after the launch of AMD’s affordable Radeon RX 480, Nvidia counters with its proposal for the mainstream market. The new GeForce GTX 1060 is more expensive than the two Radeon RX 480 models and loses two gigabytes of VRAM compared to AMD’s 8GB, but Nvidia promise to compensate with more power, and performance levels like those of a GTX 980. A couple of years ago that meant an investment of almost six hundred euros. Today, thanks to this new card, just a little more than three hundred. It is an interesting offer, but does the GTX 1060 meets all it promises?

Based on the new GP106 chip using Pascal architecture, Nvidia processor has much in common with its equivalent of the previous generation, the GM206. The company took the model that uses the current top performance and reduced its CUDA cores by half, putting it at 1280 shaders. This gave us a good product (Though not a great one) with the GTX 960, but Nvidia has taken measures this time to improve performance, and as our tests show the leap is considerable.

  • by

Recently, HP presents a laptop perfectly designed for demanding gamers that want to move around a lot.

On this occasion we review the OMEN 15-ax043dx , a computer with outstanding features for its price range and one that will allow you to go anywhere and still be able to enjoy your favorite games without much trouble.

This laptop is a great computer for those gamers looking for both power and portability in a single device. Usually, portable computers benefit more the latter than the former, but in the case of the OMEN 15-ax043dx we see that the that the scale leans a little more towards quality because it is slightly larger and heavier than average. Its dimensions are approximately 38 cm in width, 25 cm in depth and 2.5 in height (when the laptop is closed) and it weighs practically two kilograms, although depending on the characteristics you set up, it may vary slightly.

It has red accents (very typical in recent brand gamer laptop designs) although fewer than in other computers, like Asus GL552JX. This laptop feels sturdy and well manufactured so you’ll hardly have manufacturing problems with external parts, as long as you take care of your system as you should.

iOS 10, iPhone 7 and the new MacBook Pros at the September 7th Keynote

iOS 10, iPhone 7 and the new MacBook Pros at the September 7th Keynote

A week from now, Apple will have another one of their highly anticipated presentations where they will without a doubt update their smartphone line. The iPhone promises interesting changes and a more powerful processor, but it won’t come alone.

iPhone 7 or iPhone 6 SE

It still isn’t clear what the name of Apple’s new phone will be, but we do know for certain some of the new features and changes it will bring to the table. One of the main ones will be the addition of a double sensor which will allow you to take pictures with more depth of field options and new hardware effects with which we will be able to mess around. The main sensor will also certainly improve to compete with other flagship smartphone cameras like the new seventh generation Samsung Galaxy.

New Apple

Another change, and a very polemic one for that matter, is that the new iPhone will get rid of the headphone jack. An analog connection that’s still appreciated by many people but that is easily adaptable to the digital jack on the phone. This will allow the new iPhone to gain a bit more room on the inside, and will take it one step further into the future, forgetting about analog remains.
