A microwave system is a system of equipment used for microwave data transmission. The typical microwave system includes radios located high at the top of microwave towers, which are used for the transmission of microwave communications using line of sight microwave radio technology.The microwave systems are used and applied in TV,video,telephone communications, VoIP applications, extension of Fast Ethernet segment with VLAN support, Data transmission services for alternative IT operators. In microwave communication systems, it is necessary to interconnect points which are some distance apart from each other.For this purpose usually two types of transmission lines are used in microwaves. These transmission lines are: Coaxial cables and Waveguides.
Advantages of microwave systems
-Low-cost
point-to-point connection of two sides(Capital cost is generally lower).
-Installation is
quicker and easier.
-Additional service
may be provided quickly and cheaply.
-Irregular ground
difficulties are erased.
-Equalization need
only be applied for the equipment as the frequency characteristics of the
transmission path are typically constant over the transmission bandwidths(ranging
between 300MHz and 300GHz).
Disadvantages of
microwave systems:
-Adverse weather
conditions can cause severe fading and beam bending.
-It is difficult to
provide short distance branch circuits to intermediate exchanges or
subscribers.
-Restriction to
line-of-sight operation on conventional links.
-The problem of
suitable access to repeater stations from main highways and provision of
accommodation for maintenance.The provision of power supplies for the
repeaters.
-The high level of
linearity required in the repeaters poses difficulty in designing.
