Now-a-days, most of us are interested in the wireless medium when compared to wired medium like earphones (that is wired earphones to wireless earphones (or) true wireless earphones (tws)) and t.v antennas, cell phones, and any wireless computer networks. In this article, we are going to cover how the career will be in the wireless medium which is nothing but wireless communication in mobile networks mostly.
INTRODUCTION:
In general, Wireless Communication is the electromagnetic transfer of information between two or more points that are not connected by an electrical conductor. The most common wireless technologies use radio waves.
TYPES OF WIRELESS NETWORKS:
Basically, there are three types of wireless networks. They are:
- WWAN (Wireless Wide Area Network)
- WLAN (Wireless Local Area Network)
- WPAN (Wireless Personal Area Network)
In addition to this, another network called WMAN (Metropolitan Area Network)is also considered as a wireless network

PURPOSE OF WIRELESS COMMUNICATIONS:
- Wireless networks are nothing but computer networks that are not joined by cables of any kind.
- By using these wireless networks we can avoid the costly process of introducing cables into buildings or as a connection between different equipment locations.
ADVANTAGES:
- Cheaper to install and easy to maintain.
- Data transmission is faster at high speed.
- It is mostly secure.
- The wireless network can be accessed from anywhere and anytime.
- It gives rise to new opportunities.
APPLICATIONS:
- Security systems
- Television remote control
- Wi-Fi
- Cell phones
- Wireless power transfer
- Computer interface devices
- Various wireless communication-based projects.
FUTURE SCOPE:
Wireless communications is a wide field with a good number of opportunities than IT. At present we have stepped into the 5G concepts, some countries like the U.K already using these 5G networks, which means ample opportunities abroad in the future in the wireless communication sector.
CAREER DEFINITION FOR A WIRELESS COMMUNICATION ENGINEER:
Wireless communication engineers are electrical engineers that specialize in developing, manufacturing, and testing wireless technologies, such as cell phones, the satellite systems that support them, and wireless computer networks. This field of wireless communication engineering changes rapidly as new technologies develop. Wireless communication engineers must constantly update their skill sets to stay up-to-date.

WIRELESS NETWORK ENGINEERS NEED THESE SKILLS:
If you're interested in becoming a wireless network engineer, strong analytical skills and problem-solving skills are required, and you need to be knowledgeable about all aspects of network technology. By owning a background in wireless equipment, standards, protocols, and WLAN design is considered perfect.
Candidates also must be strong communicators in order to engage successfully with network technicians, vendors, and managers. Employees typically look for a bachelor’s degree in computer science, engineering, or a related field (or equivalent work experience), plus five or more years in LAN/WAN engineering and design work, including several years of specialization in wireless technologies such as Wi-Fi, WiMax and WAP. Professional certifications like Certified Wireless Network Professional (CWNP) are also valuable.
TYPICAL DUTIES FOR A WIRELESS NETWORK ENGINEER INCLUDE:
- Researching, designing, and implementing wireless networks, including all engineering requirements and resource requirements for network hardware and software
- Making suggestions for wireless network optimization, additions, and upgrades to meet business requirements.
- Conducting and recording radio frequency (RF) coverage and site overviews.
- Documenting network infrastructure and design.
JOB OPPORTUNITIES IN THE WIRELESS COMMUNICATION ENGINEERING:
There are plenty of job opportunities in these industries. To properly line up our career goals and training, we need to have a better understanding of the job titles and job profiles in wireless communications offers. More importantly, we should know about our strengths and personal attributes and choose the right job accordingly. Let us look at the various job opportunities and designations in wireless communications.
- RESEARCH ENGINEER: The role of a research engineer is to research and develop state of the art broadband wireless technologies. At present these engineers are focused on the design, development, and performance of 4G/5G systems.
- DEVELOPMENT ENGINEER: The role of development engineer in wireless communications involves the development of core network subsystems of 5G systems at the present case scenario.
- SYSTEM ENGINEER: The role of the system engineer in this wireless communications involves doing the simulation of various algorithms.
- LEAD ENGINEER: The role of a lead engineer involves developing and dealing with large software codebases, translating high-level requirements for new features, and solving debug issues in the 5G-NR domain.
- DIGITAL SIGNAL PROCESSING (DSP) ENGINEER: The role of a DSP engineer involves developing digital signal processing applications. He is also responsible for handling all the DSP applications after development.
PAYSCALE:
The average salary of wireless communication engineer India is approximately 3-7L/yr.
