High Speed Packet Access (HSPA) technology, the most widely used mobile broadband technology, has made it possible to download more data faster on third generation (3G) mobile broadband networks. The mobile telephony protocol improves the speed and capacity of current wideband code division multiple access (WCDMA) wireless broadband networks by more efficiently using the broadband spectrum. Evolved HSPA (HSPA+) uses the spectrum more efficiently, allowing for higher peak data rates and fewer delays in data transmission. These key differences between HSPA and HSPA+ generally make the second a more efficient choice for 3G networks.

The main advance in HSPA over older technologies is improvement in the protocols, or communications rules, that facilitate the movement of voice and data packets between hand-held devices and base stations. Communications network engineers work to improve the speed, amount of data per channel, number of channels, error detection, and methods of data encoding and decoding. As a result of these more efficient protocols, users of broadband-hungry multimedia services can download content quicker. Users, for example, are less likely to experience the delayed buffering of video that was indicative of older generation air interface protocols.

HSPA is the combination of high speed downlink packet access (HSDPA) and high-speed uplink packet access (HSUPA) protocols. It downloads at a peak data rate of 14 megabits per second (Mbps) and uploads at 5.8 Mbps. Specifically, it optimizes the use of the WCDMA radio bandwidth by increasing the transmission rate, sharing channel transmission, shortening the time between transmission intervals, and improving the modulation and amplitude of the signal.

UMTS is a complete network system. As such, it also covers the radio access network, the core network, and the authentication of users using the USIM cards (or Subscriber Identity Module). High Speed Downlink Packet Access (also known as HSDPA) is also part of the 3G network; however, it is of an enhanced nature. GPRS and EDGE also use the GSM network, the higher speeds of EDGE is the result of an improved technology. The third generation is the UMTS network (3G). Again, on the 3G network, the improvements HSPA (H) and HSPA+ (H+) are based, allowing faster transfer rates in the 3G network.

The plus in HSPA+ signifies an even faster and more efficient use of the spectrum. This technology provides peak download rates of up to 56 Mbps and peak uploads of 22 Mbps. The most significant advance in HSPA+ is that it can operate on an all-Internet protocol (IP) architecture — the evolutionary goal of mobile telephony. An IP architecture makes more direct connections within the broadband network, helping to lower the cost of moving a megabyte of data and reduce latency — the delays in information processing typically unnoticeable to humans. The result is an always-on connection and improved response times.

HSPA and HSPA+ technology are based on the Global System for Mobile Communications (GSM), used by 80% of carriers worldwide. Network providers are upgrading to this technology, and continuing to improve the speed and capacity of high-speed data transmissions. Handset makers are keeping pace by introducing a broad range of compatible cell phones and smart phones.

A key part of any mobile phone specification is its operating frequency bands. The supported frequency bands determine whether a certain handset is compatible with a certain network carrier.

Beside the mobile phone specifications, GSMArena is happy to also provide you with its own country-based frequency band directory. It's not operator-specific and it's helpful if you are choosing a handset to use in your home country or if you are making sure your phone will work in the country you are heading to.

2G, first introduced in 1992, is the second-generation of cellular telephone technology and the first to use digital encryption of conversations. 2G networks were the first to offer data services and SMS text messaging, but their data transfer rates are lower than those of their successors.

3G networks succeed 2G ones, offering faster data transfer rates and are the first to enable video calls. This makes them especially suitable for use in modern smartphones, which require constant high-speed internet connection for many of their applications.

4G is the fourth generation of mobile phone communications standards. It is a successor of the 3G and provides ultra-broadband internet access for mobile devices. The high data transfer rates make 4G networks suitable for use in USB wireless modems for laptops and even home internet access.

5G is the fifth generation of mobile phone communications standards. It is a successor to 4G and promises to be faster than previous generations while opening up new uses cases for mobile data. The 5G benefits range from faster speeds (up to 10x faster), much lower latency (up to 50x lower) and greater capacity allowing many more devices to be connected at the same time.
