The field of telecommunications specially wireless communications exists since the fog signals were used to carry difference type of indications whether in the days of natural disasters or in the times of war. The modern wireless communications systems include, the very popular, Cellular communications, WiFi, Bluetooth, Local Area Networks, Wide Area Networks, Personal Area Networks and many more.
For a student to purse his/her higher studies in the field of wireless communications, it is highly recommended that one should have a solid background in Probability and Stochastic Signal Processing. The book which is extensively used to study these topics is "Probability, Random Variables, and Stochastic Processes" by Athanasios Papoulis. The write has shared the power point slides, solution manual, supplementary material and much more on a web link

The recommended books for the concepts of digital communications are best explained in the following books.
Finally, the most important topics related with cellular communication networks, local area networks, wide area networks, wireless channels, equalizers, channel coding and much more can be found in

Student having degree in Wireless communications can contribute as a:
1) Radio Frequency Engineer
2) Wireless System Engineer
3) Communication and Networking Systems Engineer
4) Network Administrator
5) Systems Administrator
6) Data Communication Analyst
I found following sites very informative for the students of communication engineering.
150 Mbps with double LTE connections [1]
300 Mbps for LTE-Advanced
40ms and 60ms [1]
The advent of smartphones in the market has given a thrust to the research community working on next generation of cellular communications.
It is expected that 25 billion devices will be connected with each other by 2020.
5G network is expected to 66 times greater than 4G. Some more requirements are as follow.
Applications:
Augmented Reality and Virtual Reality.
Self driving cars
Smart Cities
Robotics
Internet of Things (IoT)
Technologies:
Software Defined Networking
Massive MIMO
Beamforming
Device to device communications
Millimeter waves (30 - 300GHz)
Beam Division Multiple Access
Small Cells
Multi-cell handover
Requirement:
Round Trip Time (RTT) of 1 ms.
latency of 1ms to 10ms
The heart to realize this is with the help of (multiple-input multiple-output) MIMO and carrier aggregation.
The
recent decades have witnessed a massive growth in the field of wireless
communications where hundreds of thousands of nodes get connected to exchange
information through wireless medium. To accommodate that surge, the mobile
communications standard from its first generation to fourth generation have
successfully been deployed throughout the world. However, this does not meet
the capacity requirement to make machine-to-machine (M2M) communications and
Internet of Things (IoT) type of communication possible, where billions of
devices will be talking to each other without wires.
To
realize such type of communications a data rate in Gbps will be required and to
achieve that target rate a new generation of mobiles, formally called Fifth
Generation (5G) of Mobile Communication has been announced. 5G in turn will
exploit the enhanced version of multiple-input multiple-output (MIMO) called massive
(MIMO) to achieve the target data rate of 10Gbps. This new idea, instead of a
single antenna, uses more than one antenna both at the transmitting as well as
receiving end.
Some of the resources to explore further the field of massive MIMO are:
