What is 3.75G?

3.75G or Cellular Generation 3.75 is much similar to 3.5G or the Cellular Generation 3.5 and 3.75G carries many similarities of the previous network itself.

3.75G stands for Evolved High-Speed Packet Access or HSPA+ or HSPA (Plus). 3.75G was introduced by 3GPP in the release version 7. HSPA+ was a killer in the technology and data transmission.

By using HSPA+ technology, data communication gone to remote areas where there is no ADSL or proper cable internet connectivity.

Technology

HSPA+ uses two technologies just like HSPA. Apart from Evolved HSDPA or HSDPA+, 3GPP introduced the Dual Carrier HSDPA or DC-HSDPA. Apart from the general need for voice transmission via the cellular network, the global demand to transmit data and large files via the wireless cellular networks has begun.

Dual Carrier HSDPA or DC-HSDPA is capable of offering a burst download speed of 42.2Mbit/s.

By using the Dual Carrier HSUPA or DC-HSUPA 3GPP offered a solution to upload speed of 5.72Mbit/s.

Apart from mobile phones, there were a new set of devices got popular among users to use the internet and get connected to the internet wireless. The devices which are built to deliver data connectivity named HSPA Plus Dongles.
