Introduction
In this article, we will answer these questions and more. We will explain what mobile communication is, what are the principles of mobile communication, and who is Gordon L. Stuber and what is his solution to the problems of mobile communication. We will also discuss the main components and advantages of the Stuber solution, which is a comprehensive approach to mobile communication that covers all aspects from the physical layer to the application layer.
What is mobile communication?
Mobile communication is the transmission and reception of information between two or more devices that are not physically connected by wires or cables. Mobile communication can use different types of media, such as radio waves, microwaves, infrared, optical, or satellite signals. Mobile communication can also use different types of networks, such as cellular, wireless LAN, Bluetooth, Wi-Fi, WiMAX, or 5G.
What are the principles of mobile communication?
The principles of mobile communication are the fundamental concepts and techniques that enable mobile communication to work. Some of these principles are:
Frequency division multiple access (FDMA): This principle divides the available frequency spectrum into several channels that can be used by different users or devices simultaneously.
Time division multiple access (TDMA): This principle divides each channel into several time slots that can be used by different users or devices sequentially.
Code division multiple access (CDMA): This principle assigns a unique code to each user or device that can be used to modulate and demodulate the signal in a shared channel.
Orthogonal frequency division multiplexing (OFDM): This principle splits the signal into several subcarriers that are orthogonal to each other and can be transmitted in parallel over a single channel.
Multipath propagation: This principle describes how a signal can travel from a transmitter to a receiver through multiple paths that have different lengths, directions, and reflections.
Diversity techniques: These techniques improve the quality and reliability of a signal by using multiple antennas, frequencies, codes, or paths.
Handover techniques: These techniques enable a seamless transition of a user or device from one network or cell to another without interrupting the communication.
Power control techniques: These techniques adjust the transmission power of a user or device according to the channel conditions and interference levels.
Who is Gordon L. Stuber and what is his solution?
Gordon L. Stuber is a professor emeritus at Georgia Institute of Technology and an expert in wireless communications. He has authored or co-authored over 300 papers and several books on the topic, including the widely used textbook "Principles of Mobile Communication". He has also received many awards and honors for his contributions to the field, such as the IEEE Fellow, the IEEE Vehicular Technology Society James R. Evans Avant Garde Award, and the IEEE Communications Society Edwin Howard Armstrong Achievement Award.
One of his most notable achievements is the development of a comprehensive solution to the challenges of mobile communication, which he presented in his book "Principles of Mobile Communication" and in his paper "A Comprehensive Approach to Mobile Communication" published in 2017. This solution, which we will call the Stuber solution, is a systematic and integrated framework that covers all aspects of mobile communication from the physical layer to the application layer. The Stuber solution aims to provide high performance, reliability, scalability, flexibility, security, and privacy for mobile communication.
The Stuber Solution: A Comprehensive Approach to Mobile Communication
The Stuber solution is based on four main pillars: (1) a unified physical layer design, (2) a cross-layer optimization approach, (3) a network function virtualization and software-defined networking architecture, and (4) a distributed and cooperative application layer design. These pillars are supported by several sub-components that we will describe in more detail below.
The main components of the Stuber solution
The physical layer
The physical layer is responsible for transmitting and receiving signals over the wireless channel. The Stuber solution proposes a unified physical layer design that can adapt to different scenarios and requirements. The unified physical layer design consists of three sub-components:
A flexible waveform design: This design allows the use of different waveforms, such as OFDM, filter bank multicarrier (FBMC), or generalized frequency division multiplexing (GFDM), depending on the channel conditions and application needs.
A dynamic spectrum access scheme: This scheme enables the efficient and fair use of the available spectrum resources by allowing multiple users or devices to share the same spectrum band in a cognitive and cooperative manner.
A massive multiple-input multiple-output (MIMO) system: This system employs a large number of antennas at both the transmitter and receiver sides to achieve high data rates, diversity gains, beamforming gains, and interference suppression.
The link layer
The link layer is responsible for providing reliable and efficient data transmission over the wireless link. The Stuber solution proposes a cross-layer optimization approach that can coordinate and optimize the operations of different layers. The cross-layer optimization approach consists of three sub-components:
A joint source-channel coding scheme: This scheme combines the functions of source coding (compression) and channel coding (error correction) to achieve optimal trade-offs between data rate, distortion, and error probability.
A cooperative diversity scheme: This scheme exploits the spatial diversity of multiple users or devices by allowing them to cooperate in transmitting or receiving data over the wireless channel.
A hybrid automatic repeat request (HARQ) scheme: This scheme improves the reliability and efficiency of data transmission by combining forward error correction (FEC) and retransmission techniques.
The network layer
The network layer is responsible for providing connectivity and routing among different nodes in the wireless network. The Stuber solution proposes a network function virtualization and software-defined networking architecture that can enable flexible and scalable network management and control. The network function virtualization and software-defined networking architecture consists of three sub-components:
A network function virtualization (NFV) platform: This platform allows the implementation of various network functions, such as firewalls, load balancers, or mobility managers, as software modules that can run on general-purpose hardware devices.
A software-defined networking (SDN) controller: This controller acts as a centralized entity that can monitor and control the behavior and configuration of different network devices and functions.
A heterogeneous network integration scheme: This scheme enables the seamless integration and interoperability of different types of wireless networks, such as cellular, Wi-Fi, or satellite networks.
The transport layer
The transport layer is responsible for providing end-to-end data delivery and quality of service among different applications. The Stuber solution proposes a cross-layer optimization approach that can coordinate and optimize the operations of different layers. The cross-layer optimization approach consists of three sub-components:
A congestion control scheme: This scheme regulates the data rate and window size of each sender according to the network conditions and feedback signals from the receivers.

A quality of service (QoS) provisioning scheme: This scheme provides different levels of service quality to different applications according to their priorities, preferences, and constraints.
The application layer
The application layer is responsible for providing various services and functionalities to the end users. The Stuber solution proposes a distributed and cooperative application layer design that can enhance the user experience and satisfaction. The distributed and cooperative application layer design consists of three sub-components:
A peer-to-peer (P2P) communication scheme: This scheme enables direct communication among users or devices without relying on centralized servers or intermediaries.
A content delivery network (CDN) scheme: This scheme improves the efficiency and quality of content delivery by caching and distributing content across multiple nodes in the network.
A social network analysis (SNA) scheme: This scheme leverages the social relationships and interactions among users or devices to provide personalized and context-aware services and recommendations.
