as a communications engineer

Xiaozaojun has been asked the following questions countless times:

every time

Xiaozaojun will explain it tirelessly

As time goes by, it becomes darker and darker.

Simply, I am too lazy to explain

Now, it’s the annual school recruitment season again

Looking at many young people

Submitted a resume for a communications position

But I don't know what these positions are specifically about.

obviously inappropriate

So, today Xiaozaojun will explain it seriously.

What does a communications engineer do?

Communications Engineer

As the name suggests, he is a communications engineer.

What is communication?

The Beijing Post edition of "Principles of Communication" wrote:

“Communication is the exchange of information.”

This sentence speaks out the essence of communication

Communication goals

It is to realize the transmission of information

in our lives

Communication is everywhere

Base stations, optical fibers, microwaves, satellites, Wi-Fi...

All are part of communication

Because it is so huge

Therefore, the process of learning it is extremely painful. . .

Our Communications (CT) Industry

Although not as famous as the IT industry

But it has always been a brother industry

From overall view

Communication is usually divided into wired communication and wireless communication

Let’s talk about “wireless communication” first

Everyone has consumer electronics such as mobile phones and pads

These products have communication capabilities

We often call it "communication terminal"

Engineers who develop, manufacture, and repair communication terminals

They are all called "terminal engineers"

The device responsible for connecting the terminal to the communication network

It is "access network equipment"

What can connect mobile phones to communication networks?

Yes, it is the base station

Engineers responsible for installing and maintaining base stations

That's "base station engineer"

If you need to improve the wireless signal in an area

Then, the location, number of base stations, orientation of antennas, etc.

All require precise calculations

There is a group of dedicated people responsible for this work

Called "Network Planning and Optimization Engineer"

(referred to as "network planning and optimization engineer")

In the operator's computer room

There are some devices for core data processing and exchange

Called: Core Network Equipment

Responsible for opening and maintaining core network equipment

" Core Network Engineer"

Between base station and core network

Between core networks

All data needs to be transferred

Device responsible for transmitting data

Called: bearer network equipment (transmission network)

Responsible for installation and maintenance of bearer network equipment

Called "Bearing Network Engineer"

Also often called a "transmission engineer"

Familiar switches, routers, firewalls and other equipment

All belong to: data communication (data communication) equipment

Positions that service, install and maintain this type of equipment

Called "Data Communication Engineer"

Some remote areas

Microwave technology or satellite technology may also be used to transmit data

Microwave engineers and satellite transmission engineers

Also belongs to "Bearer Network Engineer (Transmission Engineer)"

(Note: Satellite communications are only one type of satellite applications)

Business products:

In the core network, there are many functional products

Exists to achieve a specific function

For example, SMS, ring tones, smart network (for prepaid phones)

These products are called business products

The people responsible for these products are called "business product engineers" .

Let’s talk about wired communication

Wired communications, also known as fixed-line communications (fixed network communications)

The main difference between it and wireless communication is the terminal and access network

Main business of wired (fixed network) communications

It is fixed telephone, broadband access and IPTV, etc.

Engineers who come to your home to install these services

We are commonly known as: "Telecom Master"

A more accurate name would be: "Installation and Maintenance Engineer"

In terms of transmission network and core network

The difference between wired and wireless is not that big

I won’t repeat the introduction here.

Finally, let’s add a few more common positions:

Communication projects, especially overseas communication projects

Generally, they are Turn-Key projects.

Equipment manufacturers have to start from scratch

Complete civil construction, computer room decoration, equipment installation, wiring, etc.

All construction work

During the construction

Responsible for guiding and supervising the construction of the engineering team

It’s called: “Project Supervision”

(Somewhat similar to "senior supervisor")

After the equipment is debugged and delivered, it is in the operation stage

Special personnel are required to perform maintenance and check the operating status.

Deal with hidden dangers and solve problems in a timely manner

This seemingly simple task

It is the responsibility of the "operation and maintenance engineer"

Base station and equipment room equipment

They all use electricity

So you need a power source and a battery (to deal with power outages)

Engineers responsible for installing and maintaining power battery equipment

Called "Power (Energy) Engineer"

Power supplies, air conditioners, etc., are all supporting products for the computer room.

Therefore, such positions

Also known as "Supporting Product Engineer"

Okay, common positions related to communications

These are the above

Does everyone understand?

In the future, if someone asks you:

“What exactly does a communications engineer do?”

Please use this article to smash him to death, don't be polite!
