High-Speed Downlink Packet Access (HSPDA) is a packet-based mobile telephony protocol used in 3G Universal Mobile Telecommunications Service (UMTS) radio networks to increase data capacity and speed up download rates. Part of the HSPA standard, it offers a maximum theoretical download rate of 14.4 Mbps and accommodates simultaneous downloads, uploads and voice service. As an improved 3G cellular radio standard, it's sometimes called 3.5G or 3G+.
To accelerate downloads and reduce latency, 3GPP standardized HSDPA in its Release 5 in 2002. This greatly decreased the cost of data transmission, making mobile data access practical for many end users. Improvements in the way data is transmitted, not hardware changes, made HSDPA faster. Existing towers required only software updates. The original W-CDMA standard only used quadrature phase-shift keying (QPSK) modulation, allowing only two bits to be transmitted per symbol. HSDPA added 16 quadrature amplitude modulation (16-QAM), supporting transmittal of four bits per symbol. The radio tower could switch between QPSK for better signal integrity or to 16-QAM for higher speed, depending on signal strength.

They enabled 64-QAM, which allowed more bits to be transmitted per symbol. Multiple input, multiple output (MIMO) and Dual-Carrier HSDPA (DC-HSDPA, or Dual-Cell HSDPA) allowed several channels and cell towers to simultaneously transmit data to a single receiver, greatly increasing download capacity. These changes improved the theoretical download of HSPA+ from 28 Mbps to 42 Mbps all the way up to 168 Mbps, although such speeds were never seen in practice.
5G new radio (5G NR) technology is based on entirely new standards and does not use HSPA nor HSDPA as download standards. 5G NR still incorporates some of the same concepts as HSPA since both rely on wireless data transmission. For example, 5G NR can use 16-QAM and MIMO for faster speeds.
5G is the fifth generation of wireless network technology that will deliver faster download speeds and enhanced connectivity, providing us the potential to experience new, innovative technologies, and transform the way we live, work, and play.
5G simply increases the speed that you can download files. If a file requires 2MB of data to download it on 4G, it will still be 2MB of data to download it on 5G. You may just finish downloading it faster.
Now, restart UC Browser and download anything of 50MB. When your 3G plan will be finished after crossing 30MB, it will automatically start consuming data from your existing 2G plan. But, the wonder is, you will still get the 3G speed after crossing all the 3G data. Then you will get 3G speed in 2G plan in airtel in android.
Verizon and AT&T, on the other hand, had been relying almost exclusively on high-band deployments until their recent C-Band debuts. Verizon's fastest 5G had always relied on the 28GHz and 39 GHz millimeter wavelength spectrum bands. These higher frequencies provided download speeds that could easily exceed 1Gbps, or more than 10 times what its DSS-based network could provide. The downside is that those speeds were only available, in Verizon's own estimation, within a range of just "1,500 feet without obstructions." 2ff7e9595c
