The advantages of Wifi Projectors in modern businesses

There are many projectors that are being manufactured with the wifi functionality. Basically wireless or wifi is used so as to describe how a projector receives a picture from the source. But for every projector, there has to be at least a power cable and therefore from that point of view the wifi projector  is not wireless.

Advantages of being wireless are many. Removal of cabling issues, easy switching between multiple PC sources, increasing in mobility are some of the advantages of being wireless.

While using a wireless wifi projector there exist a small gap between the source and the projector itself. The gap is due to the processing time in order to interpret the wireless signal.

The significant limitation, however, is that certain wireless projectors are unable to display full motion video in real time. It is because they are limited by the bandwidth of the connection. However, in wireless communications the next big thing will make full motion video possible as well as make wireless connections easy and convenient. 

However there are a number of limitations of using wireless wifi projector. Delay in using the projectors and it is attributed to the processing time that is involved in interpreting the wireless signal. Also there are certain projectors like the business and the education types that fail to show complete motion video in real time and this is because of the bandwidth of the connection.

An important wifi projector that can be used as home cinema projectors are the Epson projector. These projectors are very good as these are more or less wire less. However an important aspect about Epsom projector is that they are Widi and not Wifi. Widi is a direct wireless connection between source and the Epsom home cinema projector. Moreover this projector can be well connected to home wireless network.

One needs a wireless adapter for the projector. Also to use the projectors often a wireless card is required. As far as security aspect is concerned in wireless technology security can be ensured by signal encryption. Signal encryption is a software option that usually comes with the projector software. This undoubtedly protects data but the display refresh rate gets slowed.

In modern world wireless technology is becoming significant in the wifi projector market. Almost all institutions and offices now use projectors and projector technology for their business.
