Understanding Wi-Fi Direct

We all know that a traditional Wi-Fi network is based on the presence of a wireless access point or a router and these access points basically perform three functions: physical support for wireless and wired networking, routing between devices on the network, and adding and removing devices from the network. But what would you say if one told you about a technology, a Wi-Fi technology, which does not require any router or AP, you would get pleasantly surprised. That is what the new age technology called Wi-Fi direct is all about.

Wi-Fi Direct

Wi-Fi direct is a standard, which has been developed by Wi-Fi Alliance. The standard allows two or more devices to interact directly without the presence of wireless access points or routers. The said devices can then perform several tasks such as printing, syncing, share files and many more. With Wi-Fi direct enabled devices you can play games with your partner without the physical connection between the two devices of yours. And when I say devices they could be anything from smartphones to laptops to cameras to printers to projectors to TVs.

Wi-Fi Direct

But one has to keep this fact in mind that the Wi-Fi direct has not been developed with the intention of replacing the existing standard because the Wi-Fi direct has its own set of bottlenecks such as it is not as secure as the normal standard, then it is a little difficult to control and regulate.

The main function of Wi-Fi direct is mobile sharing with less effort. Let us take an example: if we have to display some of the pics that is on our mobile phone to our Wi-Fi direct enabled TV, with the help of the said standard we can do the same without getting involved in the quagmire of passwords and establishing connection, which we need in the older standard.

What is ActiveSync?

ActiveSync is a mobile data synchronization technology and protocol developed by Microsoft. It is a program, which allows mobile devices to be synchronized. It is a bridge for data transfers between computers and mobile devices. It helps mobile devices in transferring documents, files, photos, contacts, calendars, and emails to and from the computer with ease. With ActiveSync, mobile phone is transformed into a pocket PC.

Microsoft provides two types of technology for data synchronization.

Desktop ActiveSync:

Data and information of handheld devices are synchronized with a desktop computer.  Apart from with limited backup/restore functionality, and the ability to install and uninstall mobile device applications, ActiveSync also provides for the manual transfer of files to a mobile device. Users need to connect the mobile device with the desktop to synchronize the data. Supported mobile devices can be Smartphones and PDAs running Windows Mobile, or the Windows CE operating system and other operating system.

It is to be noted that all Personal information manager (PIM) data including Email, Calendar, and Contacts can be synchronized with the ActiveSync but Tasks. Synchronization of Tasks is allowed only on Windows Mobile 5.0 devices.

ActiveSync doesn’t support all features of Outlook. Contacts grouped into subfolders are not transferred with ActiveSync.

Exchange ActiveSync:

Exchange ActiveSync provides push synchronization of contacts, calendars, tasks, and email between ActiveSync-enabled servers and mobile devices. It synchronizes directly with Microsoft Exchange Server and lets users keep e-mail, calendar data, tasks and contact information updated wirelessly via Wi-Fi or cellular network.

It is a proprietary protocol, which is licensed to a number of mobile manufacturing companies such as Apple, Palm, and Google. These companies can incorporate Exchange ActiveSync in their devices.

Many brands including Apple, Nokia, Sony Ericsson, and Sony offer products that are compatible with Exchange ActiveSync.
