Difference Between 3G and HSDPA (With Table)

Difference Between 3G and HSDPA (With Table)

The Internet and mobile communication are essential in our daily lives. At each and every moment, we need to depend on technology for communication with our colleagues or friends, etc. After going through developments, the internet speed has also been modified by developers. 3G is a modified version of the 2G network.


The main difference between 3G and HSDPA is that HSDPA is a modified version of 3G. HSDPA is also known as 3G+, 3.5G, or Turbo 3G. As HSDPA is an advanced version of 3G, the former one (HSDPA) is faster than the latter (3G).


As the name depicts, 3G is the third generation of mobile technology. It was upgraded over 2G, 2.5G, GPRS, and 2.75G EDGE networks. The main goal was to provide a better and faster network. It can provide both types of data (voice and non-voice) at the speed of three megabytes(Mb) per second.

The full form of HSDPA is High-Speed Downlink Packet Access. It is one kind of packet-based protocol network that allows data rates up to 14.4 Mbit/s in the downlink. It provides higher data speed and capacity than 3G networks. HSPA is made upon HSDPA. It is also used in radio networks to speed up transfer rates.

What is 3G?

3G is an advanced version of a 2G network that provides higher network speed than 2G and has many more advantages. 3G can provide a stable network connection for voice and non-voice data types, including calls, web browsing, videos, and email audio. 3G is widely used in IoT as it can work indoors and outdoors. 3G-type networks provide more bandwidth, security, and reliability.

The main advantage of 3G is that users can access the internet from anywhere. It works as a wireless broadband and is good for data-intensive applications. As mentioned, it can be used to access non-voice data; users will get uninterrupted video streaming on their devices. It is faster than the previous versions of mobile technology. However, there are some requirements to use the 3G network on mobile phones, as the device must be compatible with a 3G connection.

3G helps you download faster stream live videos and video conferences. It is much better than 2G. It is quite effective and widespread over the previous technology. Signal strength is much better and varies depending on the device users use. The main point to remember is that as technology develops rapidly, it will not be the fastest network for a very long time. 

What is HSDPA?

HSDPA is a short form of High-Speed Downlink Packet Access. It is called downlink packet access because it is a packet-based mobile technology protocol, and it is also used to increase the data capacity of networks and transfer rate. Like a 3G connection, HSDPA allows users to transmit voice and data without interruptions through mobile phones. It is mainly used in 3G UMTS radio networks for high-speed features. Sometimes, it is called 3.5G, 3G+ or Turbo 3G.

In this method, users can get a high-speed download rate, and the less the pipe is occupied in HSDPA, the more the user can access the internet and enjoy high-speed data transfer. It is an efficient method to allocate dedicated pipes to users. It can be said that HSDPA is a collection of adaptive modulation and coding, fast transmissions with incremental redundancy, and fast scheduling processes.

The speed provided by this method is the same as ADSL (Asymmetric Digital Subscriber Line). Many different products are using HSDPA technology. With uninterrupted connections, users can get a high-speed network to do different activities on their mobile such as music downloads, video games, conferences, broadcast television, etc.

Main Differences Between 3G and HSDPA

  1. HSDPA is faster and better than 3G because HSDPA is a modified version of 3G itself.
  2. The latency provided by HSDPA is also better than any previous versions, including 3G.
  3. HSDPA is used to improve the network type and develop an HSPA connection. HSDPA significantly enhanced the third-generation (3G) cellular telecommunication system.
  4. Mobile phones having the feature of using a 3G connection might not be reliable to use HSDPA because it will need advanced features to use the modified connectivity.
  5. 3G provides 3 Mbps, whereas HSDPA has a speed of 14.4 Mbps.


HSDPA and 3G are network types used in mobile phones and allow networks based on the UMTS to have higher data speeds and capacity. HSDPA is mainly based on a 3G connection. It is a modified version of 3G and provides a faster network than 3G. HSDPA is an additional feature of 3G that provides higher speed downlink data rates specifically for packet-switched services.

The 3G UMTS transport channels include – dedicated transport channels, broadcast channels, forward access channels, random access channels, etc. In conclusion, HSDPA is an enhanced 3G mobile telephone communication protocol that provides high-speed data.
