3G HSPA

In 2006, Ericsson was selected to build a 3G/WCDMA network in Indonesia. It provided higher data rates and enhance the end-user experience through High-Speed Packet Access (HSPA). The telecom company also provided business consulting services. Ericsson supplied radio access products and was responsible for the performance and improvement of the radio network, as well as providing operations and maintenance services. The 3G network deployment included Java, Bali and Lombok, with a focus on six major cities.

High-Speed Packet Access (HSPA)

High-Speed Packet Access (HSPA) is a collection of mobile telephony protocols that extend and improve the performance of existing 3G mobile telecommunication networks. HSPA enhances the widely used UMTS (Universal Mobile Telecommunications System) standards, significantly increasing data transmission speeds. It comprises two main technologies: High-Speed Downlink Packet Access (HSDPA) and High-Speed Uplink Packet Access (HSUPA). HSDPA, often referred to as 3.5G, boosts the download speeds, while HSUPA enhances upload speeds. Together, they allow much faster data transfer rates, lower latency, and better network efficiency, enhancing the user experience for mobile internet and multimedia services. As an evolution of 3G technology, HSPA has played a critical role in the transition towards 4G networks and beyond.

WCDMA (Wideband Code Division Multiple Access)

WCDMA (Wideband Code Division Multiple Access) is a type of 3G (third generation) mobile telecommunications technology that falls under the UMTS (Universal Mobile Telecommunications System) standard. WCDMA is a wideband spread spectrum technology that allows many users to access the same frequency band simultaneously. It uses code division to separate the signals and allocates a unique code to each user in the same frequency band. WCDMA networks offer significant improvements over earlier 2G networks, including higher data transfer rates, better network efficiency, and improved quality of service. These improvements allow for advanced services like video calling, mobile internet access, and multimedia streaming. WCDMA's more efficient use of the radio spectrum also enables it to support a greater number of users at once compared to 2G technologies.
