Wi-Fi

UWB is Radio Frequency technology that transmits binary data, using low energy and short duration impulses over a wide spectrum of frequencies. It delivers data over 15 to 100 meters and does not require a dedicated radio frequency. For example, a UWB signal centered at 5GHz typically extends across 4GHz and 6GHz. At longer distances, UWB data rates drop considerably.

The key difference among UWB and Bluetooth are of range, power, consumption and intended use. It is basically meant for short distances up to (10m). It is low power consuming than UWB.

Since FireWire is meant to deliver high speed, it is also designed to work with high power drain services. It therefore can provide much more power to the devices that connect to it. It can deliver up to 60 watts of energy. So the only difference here is of power it uses more power than UWB.

Wi-Fi really wasn't built to move audio and video, it was built for data traffic where if there's delay, while UWB is better suited for multimedia for a couple of reasons, i.e. for starters, it's throughput for surpasses that of Wi-Fi.

Some of the providers for wireless are as follows:

★ Wireless Internet- Nationwide Coverage Unlimited

★ Faster Internet on Mobile

★ New 3G BlackBerry

★ Aircel Pocket Internet

★ Reliance 3G Online Offer

★ Cisco Managed Switches

And many more.

Brand assets are available here for wireless, brand assets can also be applied to m-branding. In particular, three of the assets can be targeted directly for improvement with the m-branding methods that are available today. These are brand awareness, brand associations and brand loyalty.

The IEEE 802.11 generation is actually only the earliest standard, allowing 1-2 Mbps of bandwidth. Amendments have be made to the original standard in order to optimize bandwidth (these include the 802.11a, 802.11b and 802.11g standards, which are also called 802.11 physical standards) or to better specify components in order to ensure improved security or compatibility.

Infrastructure mode, network includes an access point when the wireless clients connect to an access point, which in turn bridges to a network. Infrastructure network can pass information through a central information hub which can be both, hardware or software device on a computer. So under this devices in a wireless network are set up to communicate through an access point.

Ad-Hoc is Latin meaning "for this purpose" so these are the networks which are basically created for some purpose. So these are the group of workstations which communicate directly witch each other to exchange information. An Ad-Hoc network is also called as a peer to peer network.

Wi-Fi is technically referred to as the 802.11 protocol. Over time, Wi-Fi has improved, giving rise to different variations of the protocol.

802.11a - This version operates at 54Mbps. It is considered as the favorite wireless LAN protocol for IP telephony.

Basically there are many standards of Wi-Fi in the industry but some popular of them are 802.11a, 802.11b, 802.11g/n. With the support of these Wi-Fi protocols we can communicate/interact among the devices at the speed of 5Ghz to 2.4Ghz dual band communication.

If we have Wi-Fi nic card so firstly we have to install their drivers and after installation if we have Wi-Fi access point then we can see the signal strength in the right corner below just open that and find the access point to connect, if access point is configured with the security, type the key to connect and enjoy the service.
