An HSPA+ Primer - Why 3.75G+ Is Better
Wireless networks have been continually improving since the introduction of cellular technology, and one of the latest innovations, HSPA+, builds on previous technologies to allow for true broadband speeds over the air. An acronym that stands for High Speed Packet Access, HSPA+ is an evolution of technologies like HSDPA and HSUPA, the third-generation, or 3G, standard that has become ubiquitous in the developed world. With speeds that can reach a theoretical maximum of 168 megabits per second (Mbps) for downloading and 22 Mbps for uploading, the new protocol is fast enough keep up with the kinds of smartphone applications and Internet usage that have become wildly popular across the world.
HSPA+ works by creating what is called a multiple-input and multiple-output (MIMO) multiple-antenna array that is supported by 64QAM higher order modulation. In the United States, the main competitor for HSPA+ is LTE, or Long Term Evolution, a network that has generally been seen as the progenitor of true 4G networks. However, LTE requires a completely new infrastructure, and current LTE devices are not significantly faster than existing HSPA+ devices. Companies like Afghan Wireless Communication Company can improve user experience vastly with an existing network using HSPA+ technology.
