Femtocells come in a variety of types and classifications, each designed to address specific network requirements and use cases. From residential femtocells that boost indoor coverage for home users to enterprise femtocells that serve large office environments, understanding the different types of femtocells is crucial for selecting the right solution.

This page provides an overview of femtocell classifications, their features, and their applications in modern cellular networks. There are various types of femtocells based on different standard technologies such as WiMAX, 2G, 3G, 4G (or LTE), etc. The femtocells are classified into class 1, class 2, and class 3 as follows.

Femtocell Class 1

The features of Femtocell class 1 are as follows:

  • It works similarly to WiFi access points (APs).
  • Transmit power (EIRP): 20 dBm or less.
  • Application: Enterprise or residential.
  • Installation: Should be handled by the end user.
  • Voice calls per channel: Typically about 4 to 6.
  • Data services: Supported.

Femtocell Class 2

The features of Femtocell class 2 are as follows:

  • Transmit power (EIRP): 24 dBm.
  • Number of users: About 6 to 12.
  • Installation: Usually handled by the femtocell service operator, though the end user can also install with assistance.

Femtocell Class 3

The features of Femtocell class 3 are as follows:

  • It has high transmit power to provide a larger coverage range.
  • It supports more users than class 1 and class 2 femtocell types.
  • Installation is taken care of by the service operator for authorized end users.
  • This type of femtocell can be deployed both indoors and outdoors, depending on the application.

Conclusion

The diverse range of femtocell types enables tailored solutions for different environments, enhancing coverage and capacity in both residential and commercial settings. By understanding the features and applications of each type, network operators can make informed decisions on femtocell deployment, ultimately improving the quality of service. As femtocell technology evolves, new types and categories will continue to emerge, offering even more specialized solutions for cellular connectivity.
