FAP (Femtocell Access Point)

Last updated on 

Introduction

Femtocell Access Point (FAP) is a small, low-power cellular base station that is designed to provide enhanced coverage and capacity for mobile communication in indoor or small areas. FAP is used to improve the quality of service and user experience for mobile subscribers in a specific area by providing a dedicated coverage and capacity. In this article, we will explain FAP in detail, including its working, types, applications, advantages, and disadvantages.

Working of FAP

FAP works by connecting to a mobile operator's network via a broadband internet connection such as DSL or cable modem. Once connected, FAP creates a small cellular network in the coverage area, providing an additional layer of coverage and capacity. When a mobile device enters the coverage area, it automatically connects to the FAP, and all voice and data traffic is routed through the FAP and back to the mobile operator's network.

The FAP acts as a miniature cellular base station, with its own radio transceiver, antenna, and signaling processing equipment. The FAP typically operates on licensed frequency bands assigned by the mobile operator and supports the same radio access technologies (RATs) as the mobile operator's network.

Types of FAP

There are two types of FAP: closed and open. A closed FAP is a proprietary device that is provided by the mobile operator to its subscribers. It is designed to work only with the mobile operator's network and cannot be used with any other network. An open FAP, on the other hand, is a device that can be used with any mobile operator's network. It is typically sold by third-party vendors and supports multiple mobile operators' networks.

Applications of FAP

FAP is primarily used in indoor or small areas where mobile coverage is poor or non-existent. Some of the common applications of FAP are:

  1. Residential areas: FAP is used in residential areas to provide enhanced coverage and capacity for mobile devices. It is particularly useful in multi-story buildings where mobile signals can be weak or non-existent.
  2. Commercial buildings: FAP is used in commercial buildings such as offices, shopping malls, and hospitals to provide dedicated coverage and capacity for mobile devices.
  3. Rural areas: FAP is used in rural areas where mobile coverage is poor or non-existent. It can be deployed in a small village or a remote area to provide mobile connectivity.
  4. Disaster recovery: FAP is used in disaster recovery scenarios where the mobile network infrastructure has been damaged or destroyed. It can be quickly deployed to provide emergency mobile connectivity.

Advantages of FAP

FAP offers several advantages over traditional cellular networks. Some of the advantages are:

  1. Enhanced coverage and capacity: FAP provides enhanced coverage and capacity in indoor or small areas where mobile coverage is poor or non-existent. It helps to improve the quality of service and user experience for mobile subscribers.
  2. Low cost: FAP is a low-cost solution compared to traditional cellular networks. It is particularly useful in residential areas where the cost of deploying a traditional cellular network can be prohibitive.
  3. Easy to deploy: FAP is easy to deploy, and it can be quickly installed by a non-technical person. It does not require any special skills or equipment.
  4. Increased security: FAP provides increased security for mobile communication as it creates a dedicated network for mobile devices. It reduces the risk of eavesdropping and interception of mobile traffic.

Disadvantages of FAP

FAP also has some disadvantages that need to be considered before deploying it. Some of the disadvantages are:

  1. Limited coverage: FAP has limited coverage and is designed to provide coverage in small or indoor areas. It cannot be used to provide coverage in large areas such as a city or a town.
  2. Limited capacity: FAP has limited capacity and can only support a limited number of simultaneous users. This can be a problem in areas where there is high demand for mobile connectivity.
  3. Dependent on broadband connection: FAP is dependent on a broadband internet connection to connect to the mobile operator's network. If the broadband connection fails or is slow, it can affect the quality of service and user experience for mobile subscribers.
  4. Interference with other networks: FAP can interfere with other cellular networks operating in the same frequency band. This can cause signal degradation and affect the quality of service for mobile subscribers.

Conclusion

FAP is a small, low-power cellular base station that is designed to provide enhanced coverage and capacity for mobile communication in indoor or small areas. It is a cost-effective solution that helps to improve the quality of service and user experience for mobile subscribers. FAP offers several advantages over traditional cellular networks, including enhanced coverage and capacity, low cost, easy deployment, and increased security. However, FAP also has some disadvantages, including limited coverage and capacity, dependence on broadband connection, interference with other networks, and the need for careful planning and management to ensure optimal performance.
