IT Management Assignment help on : Wireless & Mobile Com Networks & Technologies
(Ass 11)
- FDD: FDD is an important technique that helps the transmitter and the receiver to operate at different level of frequencies. For instance: in case of mobile wireless networks, it carries data and information from the mobile phones and it also includes the cellular systems.
- TDD: Time division duplex describes the single frequency to transmit the signals in different directions such as in the downstream as well as in the upstream directions. (Netkrom.com, 2012)
- Channel spreading: Channel spreading is useful for high accessibility in the Wi-Fi channels and also it helps to access the important points through Google. It is important for TV channels and other programs. (Khan, 2012)
- Dispreading: Dispreading is helpful to achieve the original signal and it consists of multiple signals that help to consider the important bit. For example: It helps to expand itself and it spread in different ways.
- Modulation: Modulation is the process of important signal for physical transmission and it is helpful for transmitting signal. Thus it is also known as the important process of conveying or spreading the message.
- Demodulation: It is the important activity of information bearing and also it is used in the relation and connection of radio receivers. It also detects the absence or presence of radio wave.
(Ass 12) Terrestrial infrastructures offer the specialized and high value stakes with comprehensive solutions to the clients. It also helps to implement the most complex and the efficient as well as innovative solutions. Thus it is a realistic approach of meeting demands with the help of sustainable and high development and driven policy. (Munyasya, 2009)
Terrestrial infrastructure is useful for new technology and also it helps to meet the continued demands.
There are different standards applicable in the terrestrial infrastructure such as:-
These standards are identified for interoperability among the systems and it also supports the data accessibility with video and multimedia systems. This also meets the standards for internetworking between the connection of radio and also between the other networks of transmission. So, this can strongly promote the information transfer with proper communication systems. (Fas.org, 1998)
(Ass 13) To list and to describe the functional building blocks of a basic digital wireless communication system, there are certain important points such as:-
The digital wireless communication system is useful for the binary data and it helps to transmit the data to the important path for the communication channel thus it also helps to support and implement the function of communication system. There are many designs to consider in building the system and each block of this system carry the high amount of requirements with the desired level of quality.
(Ass 14) Some limitations of wireless networks are as discussed below:-
Wireless networks are connected with the infrastructure and also it is used for providing wireless signals to the commercial areas. The ad hoc wireless signals are not highly strong when and it is easy to catch the wired signals but when the wireless signals are transferred, they are blocked with different types of obstacles and also there are a fear of unauthorized users and are a big concern for people with respect to information. The initial set up is also very complex and complicated. It is difficult in terms of set up and also it contains huge risks of security and other networks. It also possesses problems in terms of malicious traffic and also in terms of installation and other operation related issues. (Sthrath.ac.uk, 2012)
(5) The four important possible criteria’s for classifying the wireless networks are as follows:-
1. Link state routing: It includes the information about the neighbours and it has the fast changes. The node can be constructed and there will be the important mechanism of classifying the wireless network.
2. Pre-computed routing is known as proactive routing and it is the important method to meet the destination and to classify the wireless networks.
3. Flat structures: In this method, the network is at the same level and has the same function to classify the wireless network.
4. Decentralized computation: This helps to maintain the global and the complete information of the network topology and also it belongs to this category for classification. (Zou, 2012)
(Ass 31) The common examples of wireless equipments globally today are as follows:-
Cellular phones and pagers: This helps to provide the connectivity and relation with the important applications for both the business as personal uses.
Cordless sets for telephone: This is used for limited ranges in terms of devices.
Two way radios: Two way radios help in important information such as in terms of business and military communications.
Satellite television: It helps million of viewers to connect from different channels.
Global system of positioning: This mainly helps the car drivers, pilots and captains of boat and ship to locate anywhere in this earth. (Techtarget.com, 2012)
(Ass 32) The advantages of DSS are as follows:-
In terms of interference, privacy and noise rejection, the advantages are as follows:-
It is helpful for savings of time and increasing the productivity of employees. It enhances high level of effectiveness and also it improves the interpersonal communication with computerised decision support. This way, it also increases the satisfaction and promotes the learning so as it increases the organizational control.
(Ass 33) To define the following terms, there are certain important discussions such as:-
Telemetry: It is a technology that helps to measure the data and it is used in complex systems to operate properly. It helps in optimizing the performance with proper visualization.
Very small aperture terminals: It is a type of two way satellite that helps in using for the wireless transmission of real time data and information.
Spectrum planning: It provides the engineering as well as mapping devices and services that helps to meet with the capabilities.
Mobile telephone switching office: Mobile telephone switching office has a computer, a switch and is helpful to know as the cellular system. It connects to the long distance and provides important information. (Javvin.com, 2012)
Fixed wireless access: It has a high speed internet access that connects to the service providers and also it helps to maintain the internet providers.
Home radio frequency networks: It is a wireless network that supports the windows operating system and also it is positioned as the important and global extension of digitally enhanced cordless telephony.
(Ass 34) The element that needs to be considered whether a wireless or wired-line network should be implemented is known as:-
There is a requirement of proper inspection, proper control with trust and sensitivity and also it requires proper access control to consider the benefits of use for the wireless or wired line networks. (Phifer, 2012)
(Ass 35) The service or application provided by the wireless broadband network is high speed internet access and computer networking. It provides the multi level services and also proposes the strong performance, reliability and interconnectivity.
