An Insight into Technical Wireless Spectrum
We have presented a quick overview of some of the most essential wireless technologies. Nonetheless, the precise number might always be disputed owing to ongoing developments:
Cellular Networks (3G/4G/5G)
Cellular networks are the backbone of mobile communication. They are perfect for smartphones and tablets, offer broad coverage, and offer quick data rates. However, they are subject to changes in signal intensity and can be costly.
Low Power Wide Area Network (LPWAN)
Smart meters, wearables, and industrial sensors are ideal for low-power wide area networks (LPWANs). These networks are designed to transfer small data packets regularly. They are wide-ranging and reasonably priced. However, the data transfer rates are slower.

Millimeter Wave (mmWave)
Using high-frequency waves, mmWave is a specialized radar technology. It provides remarkable speed and capacity for 5G networks. However, its range is constrained, and obstacles can cause problems.
LoRaWAN
LoRaWAN is a low-power, long-range communication technology. It works well for distant applications that need to send tiny quantities of data over great distances. However, its drawback is lower data rates compared to alternative solutions.
Radio Frequency (RF)
The basis of many wireless technologies is RF. It can pass through barriers and transmit data over great distances. However, it can be costly to deploy and subject to intervention.

Zigbee
Zigbee is perfect for smart home devices and sensor networks. It uses mesh networking to provide long-range connectivity. Despite its high network capacity and low power consumption, interference may occur.
Satellite Communication
Satellite communication reaches locations outside of terrestrial networks. It provides worldwide coverage for data, phone, and video conversations. However, high prices, latency (delays), and data limitations on some plans are disadvantages.
Wi-Fi
Wi-Fi is a widely used technology that gives computers, cellphones, and other devices in a router’s range high-speed internet access. Drawbacks may include latency, security issues, and data restrictions.
Bluetooth
This popular option is for speakers and headphones. It allows short-range connectivity between devices for voice calls and data transmission. However, its range is constrained, and power consumption exceeds some alternatives.
Bluetooth Low Energy (BLE)
BLE extends battery life but has constraints on data transmission speed and range. It is designed for low-power applications such as wearables and sensors.
Radio Frequency Identification (RFID)
RFID tags wirelessly transfer data, which is used to track items and automate data collection. Despite their efficiency, they can be costly to deploy and provide security issues.
Broadcast Radio
With the emergence of new media forms, broadcast radio, a free and easily accessible means for audio content transmission, has declined. Its information is limited and interferes more with other media platforms than with other information.
Infrared
Infrared technology sends data across short distances using infrared light. However, it can’t pass through walls and is easily interfered with. Its efficacy and range are restricted.
The Bottom Line
Learning how many types of wireless technologies are there is a never-ending process. This is just a small portion of the enormous variety of wireless technologies reshaping your environment. Each of them has special benefits that meet your demands. Knowing these choices allows you to select the best technology for your needs.
