Evolved High Speed Packet Access (HSPA+), introduced in 3GPP Release 7, further increased data rates by adding 64QAM modulation, MIMO, and Dual-Carrier HSDPA operation. Under 3GPP Release 11, even higher speeds of up to 337.5 Mbit/s were possible. [3] The first phase of HSDPA was specified in 3GPP Release 5.
Dual Cell (DC-)HSUPA is the natural evolution of HSPA by means of carrier aggregation in the uplink. [9] UMTS licenses are often issued as 10 or 15 MHz paired spectrum allocations. The basic idea of the multicarrier feature is to achieve better resource utilization and spectrum efficiency by means of joint resource allocation and load balancing ...
In wireless communication, carrier aggregation is a technique used to increase the data rate per user, whereby multiple frequency blocks (called component carriers) are assigned to the same user. [1] The maximum possible data rate per user is increased the more frequency blocks are assigned to a user.
Mobile virtual network operators (MVNOs) in the United States lease wireless telephone and data service from the four major cellular carriers in the country—AT&T Mobility, Boost Mobile, T-Mobile US, and Verizon—and offer various levels of free and/or paid talk, text and data services to their customers.

Mobile phones contain both cellular and non-cellular radios used for voice and data communication. There are also two types of dual-mode phones which use cellular radio which will contain GSM/CDMA/W-CDMA as well as other technology like IEEE 802.11 radio or DECT (Digital Enhanced Cordless Telecommunications) radio.

In short, server provisioning configures servers based on resource requirements. The use of a hardware or software component (e.g. single/dual processor, RAM, HDD, RAID Controller, a number of LAN cards, applications, OS, etc.) depends on the functionality of the server, such as ISP, virtualization, NOS, or voice processing. Server redundancy ...
