Micro waveadvantages
cheaper
Freedom from acquisition rights and other governmental
requirements
Ease of communication
Ability to communicate
through oceans
No use of cables
Microwave disadvantages
insecure
Susceptible to weatherEffects like rain
Cost of design high Implementation
tricky
Antenna may split up in different
pathway
Radio wave
Offers mobility
Cheaper
Offers ease of communication
Freedom from land acquisition rights
advantages
Insecure communication
Reduce signal strength
disadvantages
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
Satellite disadvantages
Over crowding of bandwidths
High investments cost
High atmospheric losses
other unguided media
Infrared It uses infrared lights Used in everyday life like remotes , automotivegarage doors and wireless speakerCommon in pda’sLaserIt is a line of sight transmission Point to point transmissionIt can be adversely affected by weather
