Question

a) Discuss the benefits of wireless network communication with a simple example. [3 Marks]

b) Explain why wireless network communication is slower than wired network communication on most occasions. [2 Marks]

c) Wireless bridges are gaining popularity in connecting discrete campuses or business premises. Discuss the advantages and disadvantages of wireless bridges. [5 Marks]

Answer 1

a)

Wireless communication includes move of data with no physical association between at least two points. On account of this nonattendance of any 'physical framework', Wireless communication has certain benefits.

Wireless communication has a several benefits;

Cost viability

Wireless communication involves the utilization of association wires. In remote network, correspondence doesn't need expand physical framework or maintenance rehearses. Consequently the expense is decreased.

Example: Any network giving Wireless communication administrations doesn't acquire a ton of expenses, and thus, it can accuse efficiently of respect to its client charges.

Flexibility

Wireless communication empowers individuals to impart paying little heed to their location. It isn't important to be in an office or some pay phone so as to pass and get messages.

Excavators in the outback can depend on satellite phones to call their friends and family, and in this way, help improve their overall government assistance by keeping them in contact with the individuals who mean the most to them.

Convenience

Wireless communication gadgets like cell phones are very straightforward and in this way permit anybody to utilize them, any place they might be. There is no compelling reason to genuinely interface anything so as to get or pass messages.

Example: Wireless communication administrations can likewise be found in Internet innovations, for example, Wi-Fi. With no network links hampering development, we would now be able to interface with nearly anybody, anyplace, whenever.

Speed

Improvement can likewise be found in speed. The network availability were significantly better in precision and speed.

Example: A remote distant can work a framework quicker than a wired one. The wireless control of a machine can undoubtedly stop its working if something turns out badly, though direct activity can't act so quick.

Accessibility

The wireless innovation helps simple availability as the far off zones where ground lines can't be appropriately laid, are in effect effortlessly associated with the network.

Example: In rural region, online training is currently conceivable. Instructors no longer need to make a trip to distant to show their exercises. On account of live gushing of their instructive modules.

Consistent network

Consistent network likewise guarantees that individuals can react to crises moderately rapidly.

Example: A wireless mobile can guarantee you a steady network however you move here and there or while you travel, though a wired land line can't.

b)

Wireless network communication is slower than wired network communication due to the following factors:

• Distance between Wi-Fi router/modem and your device is too far
• Wi-Fi signal interrupted by “blockers”
• Interrupted from other Wi-Fi Routers/Modems
• Multiple users present in a wireless network

c)

The advantage of wireless bridge (rather than a connector in the far off PC or other wireless devices) is greater power, which implies more prominent separation and better throughput.

• It helps in expansion of physical network
• It lessens network traffic with minor division
• It makes separate collision domains, Henceforth it increments accessible transfer speed to singular hubs as less hubs share a collision domains
• Reduces collisions

While there are numerous advantages to implementing a wireless bridge, there are additionally a few drawbacks. They include:

• More muddled bandwidth management
• Possibly greater security risk
• Necessity of line-of-sight path between bridges
• At certain separations, antennae might be needed to improve signal levels
