1. What are the main driving forces of wireless evolution to higher generations?
2. In terms of capacity growth imposed on mobile networks what is the estimated growth by
2020?
3. What is your data rate expectationby 5G?
4. What are massive MIMIO?
5. What are the main areas in mobile communication systems which we can utilize to cope with
the required demands? Explain each factor in detail.
6. What aremmWave and cmWave?
Solution
Note: As there are multiple questions, only first 4 are answered.
1. The main driving forces of wireless evolution in higher generations are:
a. Speed: Provide more bandwidth to the end user
b. Coverage: Any wireless station or access point should cover larger geographical area and be
able to support higher number of users
c. Security: Should have better security to prevent misuse by hackers or data leaks.
d. Energy and cost efficiency: Provide more connectivity, coverage and bandwidth with lower
energy expenditure and lower equipment cost.
e. Support Internet of Things: Devices should be able to communicate between each other as
well as with humans.
2. In terms of capacity, mobile networks are expected to operate at more than 10Ghz speed and
support millions of users simultaneously by 2020.
3. The data rate expectation for 5G is more than 100 Mbps for each end user. There is no
standards defined till now however.
4. Massive MIMO is a large scale antenna system which deploys thousands of antennas that
operate together in a coherent and adaptive manner. Large number of antennas help to focus
transmission and reception of signal in every small region of space. It brings about huge
improvement in energy efficiency and supports thousands of users simultaneously. Massive
MIMO generally used a large number of inexpensive and low power components..
