    Description

    Experience Level: Intermediate
    Part I: Encoding and error control
    Sam is a computer science student and working on a new micro robot design. The robot
    continuously sends every two seconds a status string comprising the accelerometer
    reading (4 bits), ultrasound obstacle detection (6 bits), motor functionality (4 bits) and
    battery power level (2 bits).
    a) Calculate the data rate required for robot to remote controller communication
    b) Explain 3 types of suitable encoding techniques could be used to encode the
    status string.
    c) At a certain instance, the sensors provided data as acceleration 5 m/s2
    ,
    obstacle at 48 cm, all motors working (i.e. motor functionality 1111), and
    battery is 75%.
    i. Write the status string in binary for this instance
    ii. Represent the status string on ASK, FSK, and PSK encoding techniques
    d) Calculate the CRC for the status string derived in c) with polynomial divisor
    11001101
    e) Briefly explain some other error control and
    MITS5003 Wireless Networks and Communication
    i. For 48 subscribers what should be the subcarrier bandwidth ( fb ) ?
    ii. Propose a suitable subcarrier bit time of T to achieve orthogonality
    iii. Explain how OFDM overcomes the issue of inter symbol interference
    (ISI)
    Part III: Wi-Fi
    Prime Living is a real estate company based in Victoria and you work form them as a consultant
    network engineer. The company has decided to open a new office in South Eastern suburbs and the
    floor plan of the building is shown below. The office consists of 5 rooms and on average 8 employees
    work at each room. The lounge is used by both staff and customers and on average about 25 devices
    connect to Wi-Fi. The clients wants you to design the network for them with at least 100 Mbps data
    rate for all wireless connections. As resources you’ve got one distribution system and few access
    points of 10 m range.

    MITS5003 Wireless Networks and Communication
    a) Design the network specifying the locations of access points and distributions
    system showing the backbone network.
    b) Calculate the BSS and ESS sizes
    c) Calculate the throughput for the DS
    d) Recommend a suitable IEEE substandard for the network and give reasons for
    your choice
    e) Recommend suitable security strategies for the network
