Page 2: Guided media

Micro waveadvantages

cheaper

Freedom from acquisition rights and other governmental

requirements

Ease of communication

Ability to communicate

through oceans

No use of cables

Page 3: Guided media

Microwave disadvantages

insecure

Susceptible to weatherEffects like rain

Cost of design high Implementation

tricky

Antenna may split up in different

pathway

Page 4: Guided media

Radio wave

Offers mobility

Cheaper

Offers ease of communication

Freedom from land acquisition rights

advantages

Insecure communication

Reduce signal strength

disadvantages

Page 5: Guided media

Satellitesadvantages

Area coverage is large

Maintenance easy

Can cover large areas of the earth

Useful in sparsely populated areas c loses

Disadvantages

High atmospheric loses

High investment

costs

Page 6: Guided media

Satellite disadvantages

Over crowding of bandwidths

High investments cost

High atmospheric losses
