Broadband Wireless Access (BWA) is a technology that provides high-speed wireless connectivity to users. It is used for delivering broadband services to customers in a wireless manner, without the need for cables or wires. BWA is a wireless technology that provides high-speed data and voice services, which can be used for internet, voice, video, and data communications.
BWA can be categorized into two types, which are fixed and mobile. Fixed BWA is used to provide wireless connectivity to a specific location, such as a building, campus, or community, whereas mobile BWA is used for providing wireless connectivity on-the-go, such as in a vehicle or while walking.
In this article, we will discuss the technical aspects of BWA, including its various types, technologies, and applications.
Types of Broadband Wireless Access
As mentioned earlier, BWA can be classified into two types, which are fixed and mobile. Both types of BWA have their own unique features and applications.
Fixed Broadband Wireless Access
Fixed BWA is used to provide wireless connectivity to a specific location, such as a building, campus, or community. It is commonly used as an alternative to wired networks, such as cable or DSL. Fixed BWA is used to provide high-speed data and voice services to customers, without the need for cables or wires. This technology is commonly used in rural areas where it is difficult to provide wired networks.
The technology used for fixed BWA is generally based on IEEE 802.16 standards, which is also known as WiMAX (Worldwide Interoperability for Microwave Access). WiMAX is a wireless technology that provides broadband connectivity over long distances. It can provide high-speed data and voice services to customers in a wireless manner. WiMAX is designed to provide a range of up to 50 km, with data rates of up to 75 Mbps.
Mobile Broadband Wireless Access
Mobile BWA is used for providing wireless connectivity on-the-go, such as in a vehicle or while walking. It is commonly used for mobile devices, such as smartphones, tablets, and laptops. Mobile BWA is used to provide high-speed data and voice services to customers, without the need for cables or wires. This technology is commonly used in urban areas where it is difficult to provide wired networks.
The technology used for mobile BWA is generally based on cellular networks, such as 3G, 4G, and 5G. Cellular networks provide wireless connectivity to mobile devices over long distances. They can provide high-speed data and voice services to customers in a wireless manner. Cellular networks are designed to provide a range of up to 50 km, with data rates of up to 1 Gbps.
Technologies Used in Broadband Wireless Access
There are various technologies used in BWA, which are discussed below:
WiMAX
WiMAX is a wireless technology that provides broadband connectivity over long distances. It can provide high-speed data and voice services to customers in a wireless manner. WiMAX is designed to provide a range of up to 50 km, with data rates of up to 75 Mbps. WiMAX is based on IEEE 802.16 standards, which provide interoperability between different vendors’ equipment.
Wi-Fi
Wi-Fi is a wireless technology that provides wireless connectivity within a short distance, typically within a building or a campus. Wi-Fi is commonly used for providing wireless connectivity to mobile devices, such as smartphones, tablets, and laptops. Wi-Fi is based on IEEE 802.11 standards, which provide interoperability between different vendors’ equipment.
3G
3G is a cellular technology that provides wireless connectivity to mobile devices. It can provide high-speed data and voice services to customers in a wireless manner. 3G is designed to provide a range of up to 50 km, with data rates of up to 2 Mbps. 3G is based on CDMA (Code Division Multiple Access) and WCDMA (Wideband Code Division Multiple Access) standards, which provide interoperability between different vendors’ equipment.
4G
4G is a cellular technology that provides wireless connectivity to mobile devices. It can provide high-speed data and voice services to customers in a wireless manner. 4G is designed to provide a range of up to 50 km, with data rates of up to 1 Gbps. 4G is based on LTE (Long Term Evolution) standards, which provide interoperability between different vendors’ equipment.
5G
5G is a cellular technology that provides wireless connectivity to mobile devices. It can provide high-speed data and voice services to customers in a wireless manner. 5G is designed to provide a range of up to 50 km, with data rates of up to 10 Gbps. 5G is based on NR (New Radio) standards, which provide interoperability between different vendors’ equipment.
Applications of Broadband Wireless Access
There are various applications of BWA, which are discussed below:
Internet Access
BWA is commonly used for providing internet access to customers. It can provide high-speed internet services to customers in a wireless manner, without the need for cables or wires. BWA can be used as an alternative to wired networks, such as cable or DSL. BWA is commonly used in rural areas where it is difficult to provide wired networks.
Voice Services
BWA can also be used for providing voice services to customers. It can provide high-quality voice services in a wireless manner, without the need for cables or wires. BWA can be used as an alternative to traditional phone networks, such as PSTN (Public Switched Telephone Network).
Video Services
BWA can also be used for providing video services to customers. It can provide high-quality video services in a wireless manner, without the need for cables or wires. BWA can be used for streaming video services, such as Netflix, YouTube, and Amazon Prime Video.
Public Safety Services
BWA can also be used for providing public safety services, such as emergency communication and surveillance. BWA can provide high-speed data and voice services to emergency responders, such as police, firefighters, and ambulance services. BWA can also be used for surveillance, such as video cameras and drones.
