Network infrastructure setup
Network infrastructure setup relates to both hardware and software resource sharing and the capacity of the network components to share mediums effectively while also providing excellent signal transmission and link management. In order to setup a network infrastructure let us concentrate on the first and most important step involved in its establishing i.e. the setting up of a network’s physical layer. This layer is responsible for providing all the mechanical, electrical, practical and technical means of physical connections and interfaces between the various components and ports of a network.
If your organization is equipped with wireless facilities, which in actual is now fast becoming an essential constituent of any business or firm, then there are quite a few rules concerning the various network components that one should be aware of. These essential components that form a part of wireless network infrastructure setup have been described below in detail:
Station Types: Typically, wireless networks have some predefined characteristics concerning the various network terminals. These help in classifying a station type and may be any one or more of the following:
• Station types may be identified on the type of the terminal whether it is a source or a sink or merely a relay station or a complex combination of the two.
• The type of data being transmitted or received by the terminal, its functionality all help in determining the station type.
Channel Media: The next step involved in setting up a wireless network infrastructure is determining the channel medium which in turn helps define the bandwidth and geographical span of the LAN in use.
As wireless LANs are usually designed in the ISM bands, which implies that they are synchronized for the amount of radiation per device, these bands are exceedingly susceptible to interference and security breaches.
Physical Link: Establishment of a physical link for a WLAN is possible in more than one way. This is possible due to the fact that a wireless channel is a shared medium.
One may choose from either ad hoc or infrastructure LAN mechanisms. The former mechanism allows a wireless link to be established between the wireless terminals directly. The latter type makes use of a central access point in order to establish the connection.
Signal Conditioning. In order to maximize the bandwidth utilization and enable fast and easy recognition of the receiving signal by the receiver device it is necessary to employ signal conditioning in the network infrastructure. There are a number of signal conditioning techniques that are available, for example: base-band modulation schemes, such as NRZ-I, Manchester, and differential Manchester. However, if you plan to setup an infrastructure for a wireless network then it is important to mention that the use of base-band modulation techniques is not recommended as wireless channels do not allow frequencies close to zero Hz to travel efficiently through them.
