Wireless communication protocols have evolved rapidly since the introduction of 802.11 Legacy over a decade ago. Over the last 10 years we have seen efficiency and performance increases on all fronts‚ which have lead to greater range and faster transfer speeds. With Legacy 802.11 protocols‚ speeds maxed out at around 2 Mbits/sec and indoor range was only about 20 meters. In 1999‚ the 802.11 protocol got a couple of amendments in the form of 802.11a and 802.11b. Both offered higher speeds and slightly

What risks and safeguards are associated with wireless communication? What is “war driving” or “war flying”? Are you comfortable (or would you use) a wireless “hot spot” to do computer work? What safeguards might you use in accessing an unprotected (public) wireless communications? Are you more at risk using a wireless connection via laptop or a connection via a smart phone? Transmissions over wireless networks can be intercepted by any suitable device within the transmission radius. If a network

The aim of this report is to research wireless antennas and differences between them. Antennas are included 3 types: omnidirectional‚ semi-directional‚ and highly-directional. Any antenna has three fundamental properties: gain‚ directional and polarization. Omnidirectional Antennas. We can use this antenna in a: point-multipoint link‚ warehouse‚ hotspot‚ trade show‚ airport. The omnidirectional antennas transmit a signal in all directions‚ it is known dipole ("non-directional") antenna. The

Wired or Wireless‚ What’s the Difference? The main difference between a wired and wireless data communication infrastructure is the existence of physical cabling. The same‚ or similar techniques are employed for both types of data communication infrastructure in terms of the core elements of essential network services. The basic difference between a wired and a wireless network is self-explanatory. A wired network uses wires to communicate whereas a wireless network uses radiowaves. Let us look
