WCDMA 3G

In 2006, Nokia supported Ukrtelecom's Utel branch in opening the first WCDMA 3G/HSDPA network in Ukraine, enabling the operator to provide new end-user services including high speed data transfer for WAP, Internet access, video calls, and streaming for video and audio. High performance Nokia HSPA is a software upgrade to Nokia WCDMA networks that is made up of two key technologies: HSDPA (High Speed Downlink Packet Access) and HSUPA (High Speed Uplink Packet Access), enabling mobile broadband with data speeds of up to 14.4 Mbps in the downlink and up to 5.8 Mbps in the uplink. The technology provided data services that are ten times faster than current 3G networks.

Features of the WCDMA 3G/HSDPA network

1. Wideband Code Division Multiple Access (WCDMA): This is the 3G technology used in the UMTS (Universal Mobile Telecommunications System) standard. It uses wideband spread spectrum technology, which allows many users to share the same frequency band simultaneously.
2. High Speed Downlink Packet Access (HSDPA): Often referred to as 3.5G, HSDPA is an upgrade to WCDMA that improves data speeds. It provides faster data rates and lowers latency, improving user experience for applications like video streaming and web browsing.
3. Increased Capacity: WCDMA has increased capacity compared to 2G networks. It can accommodate more users simultaneously, particularly in urban areas or during peak usage times.
4. Better Voice and Data Integration: WCDMA provides simultaneous voice and data services. This means that users can use data services while making a call.
5. Improved Spectral Efficiency: WCDMA makes better use of available frequency spectrum, providing higher capacity and performance.
6. Global Roaming: WCDMA is used in 3G networks across the world, allowing for global roaming.
