History of Wireless Technologies

The development of Wireless technology owes it all to Michael Faraday – for discovering the principle of electromagnetic induction, to James Maxwell – for the Maxwell’s equations and to Guglielmo Marconi – for transmitting a wireless signal over one and a half miles. The sole purpose of Wi-Fi technology is wireless communication, through which information can be transferred between two or more points that are not connected by electrical conductors.Wireless technologies were in use since the advent of radios, which use electromagnetic transmissions. Eventually, consumer electronics manufacturers started thinking about the possibilities of automating domestic microcontroller based devices. Timely and reliable relay of sensor data and controller commands were soon achieved, which led to the discovery of Wireless communications that we see everywhere now.HistoryWith the radios being used for wireless communications in the World war era, scientists and inventors started focusing on means to developing wireless phones. The radio soon became available for consumers and by mid 1980s, wireless phones or mobile phones started to appear. In the late 1990s, mobile phones gained huge prominence with over 50 million users worldwide. Then the concept of wireless internet and its possibilities were taken into account. Eventually, the wireless internet technology came into existence. This gave a boost to the growth of wireless technology, which comes in many forms at present.Applications of Wireless TechnologyThe rapid progress of wireless technology led to the invention of mobile phones which uses radio waves to enable communication from different locations around the world. The application of wireless tech now ranges from wireless data communications in various fields including medicine, military etc to wireless energy transfers and wireless interface of computer peripherals. Point to point, point to multipoint, broadcasting etc are all possible and easy now with the use of wireless.The most widely used Wi-Fi tech is the Bluetooth, which uses short wavelength radio transmissions to connect and communicate with other compatible electronic devices. This technology has grown to a phase where wireless keyboards, mouse and other peripherals can be connected to a computer. Wireless technologies are used:· While traveling· In Hotels· In Business· In Mobile and voice communication· In Home networking· In Navigation systems· In Video game consoles· In quality control systemsThe greatest benefit of Wireless like Wi-Fi is the portability. For distances between devices where cabling isn’t an option, technologies like Wi-Fi can be used. Wi-fi communications can also provide as a backup communications link in case of network failures. One can even use wireless technologies to use data services even if he’s stuck in the middle of the ocean. However, Wireless still have slower response times compared to wired communications and interfaces. But this gap is getting narrower with each passing year.Progress of Wireless technologyWireless data communications now come in technologies namely Wi-Fi (a wireless local area network), cellular data services such as GPRS, EDGE and 3G, and mobile satellite communications. Point-to-point communication was a big deal decades ago. But now, point-to-multipoint and wireless data streaming to multiple wirelessly connected devices are possible. Personal network of computers can now be created using Wi-Fi, which also allows data services to be shared by multiple systems connected to the network.Wireless technologies with faster speeds at 5 ghz and transmission capabilities were quite expensive when they were invented. But now, almost all mobile handsets and mini computers come with technologies like Wi-Fi and Bluetooth, although with variable data transfer speeds. Wireless have grown to such a level, where even mobile handsets can act as Wi-Fi hotspots, enabling other handsets or computers connected to a particular Wi-Fi hotspot enabled handset, can share cellular data services and other information. Streaming audio and video data wirelessly from the cell phone to a TV or computer is a walk in the park now.Wireless Technology today, are robust, easy to use, and are portable as there are no cables involved. Apart from local area networks, even Metropolitan Area networks have started using Wi-fi tech (WMAN) and Customer Premises Equipment ( CPE ). Aviation, Transportation and the Military use wireless technologies in the form of Satellite communications. Without using interconnecting wires, wireless technologies are also used in transferring energy from a power source to a load, given that the load doesn’t have a built-in power source.However, the fact that ‘nothing comes without a drawback’ or ‘nothing is perfect’ also applies to Wi-fi technology. Wireless technologies still have limitations, but scientists are currently working on it to remove the drawbacks and add to the benefits. The main limitation is that Wireless technologies such as Bluetooth and Wi-Fi can only be used in a limited area. The wireless signals can be broadcasted only to a particular distance. Devices outside of this range won’t be able to use Wi-Fi or Bluetooth. But the distance limitation is becoming reduced every year. There are also a few security limitations which hackers can exploit to cause harm in a wireless network. But Wireless technologies with better security features have started to come out. So this is not going to be a problem for long.Speaking of progress, Wi-Fi technology is not limited to powerful computers and mobile handsets. The technology has progressed enough that Wi-Fi enabled TVs and microwaves have started appearing in the markets. The latest and the most talked-about wireless technology is the NFC or Near Field Communication, which lets users exchange data by tapping their devices together. Using wireless technologies are not as expensive as it used to be in the last decade. With each passing year, newer and better wireless technologies arrive with greater benefits.

How to Utilize Colors strategically in website design

Color can be a powerful tool for website design. It can draw attention, convey emotion, inspire an atmosphere of desire, or directing conversation all these and more are accomplished through the clever and well-planned application of color. Similar to layouts and style of your words the color visitors will see on your website will determine the way they feel about it and whether or whether they’ll return.

What makes color important for Website Design

Colors can increase the visibility of your brand and can also entice visitors to your website to engage. The impression they form subconsciously about your company could be based on your website’s color scheme. So when a web design firm is first deciding to design your site, they first look at two aspects – the feelings your brand wants to create, and the cultural and philosophical contexts that it would like to be in line with. This is the initial step to choosing the right colors for the design of your website.

Color Psychology – colors trigger emotions
Psychology of color is the term used to describe the impact that color can influence a person’s feelings behaviours, feelings, and moods. Although the rules are not fixed in stone, we are drawn to certain colors because they affect our feelings. The context here is crucial. Red could mean fear and risk to certain people, but enthusiasm and passion to other people. When using colors in web design, it should blend seamlessly with aspects of the website including copy, typography, and images.

Below are some colors and the emotions they bring. While they aren’t fixed in stone, these are generalizations and can have an impact on the people who are watching. This will help you determine the color of your choice in accordance with how you would like your viewers to feel and the actions you would like them to do.

Cultural Context
While various colors could have different meanings for individuals, colors can are also associated with cultural significance. In many Western countries, it is believed that black symbolizes mourning and death, while the same color is used in a variety of Eastern nations.

The color Red is thought to be associated with focus and pressure in Western culture, while many Eastern cultures believe it is associated with luck. It is important to consider the context when making a selection of colors. Most of the time, you’ll prefer to select the colors of your company based on the audience you want to reach. Based on the location where your market is located the colors displayed on your site could convey significant messages in different ways.

However, it’s not always the case particularly when it comes to massive and well-known brands that have images already embedded in our consciousness. The red color of Coca-Cola or KFC, for example, will typically have no negative associations anymore, considering the extent to which well-known and loved they are.

The Basics of Color Theory

Theory of Color is an established set of rules that can be helpful in understanding and creating complementary colors and combinations. These basic principles can assist you in creating a color colour scheme that is appropriate to your company’s specific requirements.

Primary Colors: They are three in total – blue, red and yellow.

Secondary Colors: These colors are created using primary color combinations like the green (yellow and blue) and orange (yellow and red) along with purple (blue plus red).

Tertiary Colors: These are colors made by mixing primary with secondary color.

Shades, Tints Tones: The colors listed above are referred to by some as “pure shades”. But, these colors can be used to create other colors. Tints are created by adding white to pure colors, which makes them less intense and lighter. Shades are created by adding a lack and making them heavier and more powerful. It is possible to use white and black in different levels to create tones using pure hues.

Contrast: Contrast is the perception of the difference between two hues when put next to each other. The greater the contrast, the more the two colours stand out from one another. This is a crucial idea since different levels of contrast can make an entirely different look to your site. A text that is colored and placed with a background that is low in contrast could cause issues with reading. Contrast may also make certain elements stand out (or even deflect attention from particular elements when used effectively) in your website and can make them stand out visually.

Color Models

When designing graphic designs, color is defined using color models. This is due to the fact that it is possible to find millions of different colors and it’s impossible to list every single one. The standards were developed to allow us to easily define colors by using numbers.

RGB Model: The model that is used when working with designs on the screen. RGB refers to Red as well as Green and Blue. The three colors are assigned a value of zero to 255, and the different combinations give us different shades. The colors are typically displayed as color codes, six-digit hexadecimal code numbers. It’s an “additive” color model.

CMYK Model: This model is utilized to print for printing purposes. It is a combination of Cyan, Magenta, Yellow and Black Each color is described using its proportion of these colors. It is a “subtractive” colour model.

the LAB Model: The word LAB means lightness, A channel as well as B channel. It’s a more complicated model. It includes the lightness factor, which is a range of zero to 100, an A component that is located on the red-green axis, and a B component that is located on the blue and yellow axis. This means that the color description is more akin to human perception when compared to RGB and CMYK models.

Making Color Palettes

The first color you select for your website is the primary color of your company’s branding (Red is the color of Coca Cola, for example). This is where the psychology of color is particularly useful. The color you choose is in accordance with the feelings and the personality you want to communicate. Following that, you build your color palette with the colors that complement the base color. This is the time when the color wheel is used.

Color Wheel: A color wheel can be described as an instrument that is used to illustrate the connection between different colors. It’s basically an abstract drawing that arranges different hues of color within a circle.

With the aid of a color wheel, you have are five primary types of color palettes you can make with the help of color wheel

Analogous Palette: Analogous colors are put on top of each other in the form of a color wheel. They are in low contrast against each other and work well together, giving an elegant effect.

Monochromatic Palette: The palettes are made up of one hue that is distinctive, and is complemented by elements of various colors and hues. The palette is appealing to look at. To prevent an uninteresting look it’s beneficial to add different colors, or even complimentary elements to your website.

The HTML0 Triad Palette – This palette is composed of three colors, which are evenly spaced from each other on the wheel of color. This method should be employed with care, and not only to select colours that go well with each other and blend well but also to utilize the colors in a way that doesn’t appear too cluttered and loud.

Complementary Palette: The Complementary palette is made up of colors that are on opposite sides of the spectrum of colors. This is a great way to create striking art designs that attract attention to certain parts of your site.

Split-complementary Palette: The palette is similar to complement palettes, but it has another color placed beside one of the colors that complement each other on the wheel of color. If used correctly this design can be effective in creating a natural appearance without too much sound.

Effective Tools to Inspire

Inspiration for new colors can be found everywhere from competitor websites to nature, and the beautiful outdoors. It’s also beneficial to keep abreast of the new trends in branding. Here are some helpful tools to help you get going with fresh color concepts right away.

Pinterest The website Pinterest is a wealth of color palette concepts developed by designers from all over the globe. They can be an incredible source of ideas.

Pantone: The color Pantone has been the leading company in the area of color. It is an index of color that determines the various shades of the various hues. The most recent trends in color in fashion and design generally stem from pantone.

color-scheme Creation Websites: There are many dedicated color websites for designers that can assist you in creating colors and play around with the palettes in any way you would like. This is a fantastic opportunity to try out and create new palettes for yourself. Websites such as Adobe Color Wheel, Color Collective along with Design Seeds can be great for quick ideas.


While color alone may not be the sole factor in website design, it does play an important role. If used properly and in a way that is appropriate, the color(s) that you use be a defining factor for your company’s image. Utilizing the tricks and tips that were mentioned earlier, you will not have any issues using colors in your web design to get the most impact.
