Wireless cellular tower for a 5G signal.

What are the Types of Cellular Wireless Tech and Their Best Uses?

Wi-Fi is changing the world as we know it, especially as it comes into contact with hardware (or the Internet of Things). Because of IoT’s diverse and multifaceted nature, you will find a wide range of communication solutions among different techs.

So let’s look at one of the most powerful wireless services, cellular towers, and the different phases this service went through.

Types of Wireless Services – Cellular Technology

The currently established consumer mobile market relies heavily on cellular networks, especially now, with 5G offering browsing speeds of 60 Mbps to 1 Gbps. Although cellular networks are relatively costly, they provide a very convenient solution for the public when outdoors.

Organizations use cellular networks much more extensively, especially when keeping an eye on the front-line workers and their communication with headquarters.

However, the high-power requirement for cellular networks often makes it unviable for use in battery-operated IoT applications.

5G uses quite a lot of power because of the sheer speed and signal strength its tower generates. It’s widely being adopted by organizations across the US and the government for tasks, such as:

  • Real-time video surveillance
  • Employee safety
  • Mobile delivery of data sets
  • Remote control of delivery drones
  • Fleet management
  • Industrial automation, especially those that are time-sensitive, and more.

Cellular technology uses a lot of power because it has many interconnected transmitters instead of one large one. This, in turn, allows for higher bandwidth, better speeds, and a much stronger signal being generated.

Here are different types of cellular technology being adopted by IoT and other wireless services.


A prime example of technology still using GSM (Global System for Mobile) communication systems is the ICS (Industrial Control Systems) and SCADA (Supervisory Control and Data Acquisition) control system architecture.

GSM is the original “2G” network from 1991. It has global coverage and is used primarily in industrial controls.


Geared mostly towards the US only, Code Division Multiple Access (CDMA) is also used in industrial control modules or other short-range communicational needs.


The third generation of GSM or 3G could transfer up to 200,000 bits (0.025 Mb) per second initially. However, later versions got upgraded to 8 Mbps. The 3G network may shut down soon as it is being replaced by 4G and 5G.

3G cellular signals are used by some IoT engineers when testing machinery because it is relatively cost-effective.


This is the fourth generation of GSM, and it’s widely used for commercial communications still. It received the HSP (High-Speed Packet Access), LTE (Long Term Evolution), AWS (Advanced Wireless Services), XLTE, and VoLTE upgrades over time to support the commercial and industrial requirements, especially for long-range communication.

Later versions could swap seamlessly between Wi-Fi and cellular networks during communications.

The Narrowband IoT 4G wireless services have been used most extensively by organizations because of the raw power of these signals and ranges. Construction sites and surveyors often use narrowband when headed to remote sites.

Applications of cellular wireless services include:

  • Healthcare
  • Utility (specifically electrical)
  • Agriculture
  • Energy sector
  • Wearables
  • Self-driving/connected cars
  • Smart cities or self-sustaining cities (almost every bit of technology is interconnected with cellular, not Wi-Fi)
  • Manufacturing plants, and more.
