Qualcomm Gobi is a family of embedded mobile broadband modem products by Qualcomm. Gobi technology 2 was designed to allow for any product with the embedded solution to connect to the internet anywhere a wireless carrier provides data coverage. One of the more notable products that contain a Gobi modem is the iPhone 4 for Verizon, which contains a MDM6600, however it does not take advantage of the support for HSPA+.
On October 23, 2007, Qualcomm announced the first set of Gobi-enabled chipsets to be commercially available in the second quarter of 2008. [1] [2] The first chip produced by Qualcomm, the MDM1000, gained support from PC manufacturer HP [3] as well as wireless carriers Vodafone and Verizon. [4]
Two years later, on February 11, 2009, Qualcomm announced the second generation of Gobi-enabled chipsets, the MDM2000. The MDM2000 added support for additional frequencies which are prevalent in Japan and rural Europe, improved uplink capabilities and other software upgrades. [5]
The third, and most recent, generation of Gobi-enabled chipsets was announced on March 23, 2010 however this generation consists of a total of 6 different chips which support different ranges of wireless standards and data rates. The reasoning behind the multiple chips was to address additional markets such as USB modems, e-readers, gaming devices and machine to machine commercial applications. [6] Qualcomm also introduced software enhancements for select Mobile Data Modem (MDM) chipsets that enabled “a common Gobi software interface (API) across multiple hardware platforms.” [7]
The main feature of the Gobi modems is their support of multiple wireless standards such as GSM and CDMA. Newer modems also have support for 4G wireless standards such as HSPA+ and LTE, with a notable omission of WiMax. [7] [8] The extensive support of wireless standards allows consumers to choose between multiple carriers based on the modem present in their device. What standard the modem supports and at what rates depends on the chip being used.

The Universal Mobile Telecommunications System (UMTS) is a third generation mobile cellular system for networks based on the GSM standard. Developed and maintained by the 3GPP, UMTS is a component of the International Telecommunication Union IMT-2000 standard set and compares with the CDMA2000 standard set for networks based on the competing cdmaOne technology. UMTS uses wideband code-division multiple access (W-CDMA) radio access technology to offer greater spectral efficiency and bandwidth to mobile network operators.
Bell Mobility Inc. is a Canadian wireless network operator and the division of Bell Canada which offers wireless services across Canada. It operates networks using LTE and HSPA+ on its mainstream networks. Bell Mobility is the third-largest wireless carrier in Canada, with 10.1 million subscribers as of Q3 2020.
4G is the fourth generation of broadband cellular network technology, succeeding 3G and preceding 5G. A 4G system must provide capabilities defined by ITU in IMT Advanced. Potential and current applications include amended mobile web access, IP telephony, gaming services, high-definition mobile TV, video conferencing, and 3D television.
Evolution-Data Optimized is a telecommunications standard for the wireless transmission of data through radio signals, typically for broadband Internet access. EV-DO is an evolution of the CDMA2000 (IS-2000) standard which supports high data rates and can be deployed alongside a wireless carrier's voice services. It uses advanced multiplexing techniques including code-division multiple access (CDMA) as well as time-division multiplexing (TDM) to maximize throughput. It is a part of the CDMA2000 family of standards and has been adopted by many mobile phone service providers around the world particularly those previously employing CDMA networks. It is also used on the Globalstar satellite phone network.
E-UTRA is the air interface of 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) upgrade path for mobile networks. It is an acronym for Evolved UMTS Terrestrial Radio Access, also known as the Evolved Universal Terrestrial Radio Access in early drafts of the 3GPP LTE specification. E-UTRAN is the combination of E-UTRA, user equipment (UE), and a Node B.
High Speed Packet Access (HSPA) is an amalgamation of two mobile protocols—High Speed Downlink Packet Access (HSDPA) and High Speed Uplink Packet Access (HSUPA)—that extends and improves the performance of existing 3G mobile telecommunication networks using the WCDMA protocols. A further-improved 3GPP standard called Evolved High Speed Packet Access was released late in 2008, with subsequent worldwide adoption beginning in 2010. The newer standard allows bit rates to reach as high as 337 Mbit/s in the downlink and 34 Mbit/s in the uplink; however, these speeds are rarely achieved in practice.
Mobile broadband is the marketing term for wireless Internet access via mobile networks. Access to the network can be made through a portable modem, wireless modem, or a tablet/smartphone or other mobile device. The first wireless Internet access became available in 1991 as part of the second generation (2G) of mobile phone technology. Higher speeds became available in 2001 and 2006 as part of the third (3G) and fourth (4G) generations. In 2011, 90% of the world's population lived in areas with 2G coverage, while 45% lived in areas with 2G and 3G coverage. Mobile broadband uses the spectrum of 225 MHz to 3700 MHz.
Evolved High Speed Packet Access, HSPA+, HSPA (Plus) or HSPAP, is a technical standard for wireless broadband telecommunication. It is the second phase of HSPA which has been introduced in 3GPP release 7 and being further improved in later 3GPP releases. HSPA+ can achieve data rates of up to 42.2 Mbit/s. It introduces antenna array technologies such as beamforming and multiple-input multiple-output communications (MIMO). Beam forming focuses the transmitted power of an antenna in a beam towards the user's direction. MIMO uses multiple antennas at the sending and receiving side. Further releases of the standard have introduced dual carrier operation, i.e. the simultaneous use of two 5 MHz carriers. HSPA+ is an evolution of HSPA that upgrades the existing 3G network and provides a method for telecom operators to migrate towards 4G speeds that are more comparable to the initially available speeds of newer LTE networks without deploying a new radio interface. HSPA+ should not be confused with LTE though, which uses an air interface based on orthogonal frequency-division modulation and multiple access.
MediaTek Inc. is a Taiwanese fabless semiconductor company that provides chips for wireless communications, high-definition television, handheld mobile devices like smartphones and tablet computers, navigation systems, consumer multimedia products and digital subscriber line services as well as optical disc drives.
In telecommunications, long-term evolution (LTE) is a standard for wireless broadband communication for mobile devices and data terminals, based on the GSM/EDGE and UMTS/HSPA standards. It improves on those standards' capacity and speed by using a different radio interface and core network improvements. LTE is the upgrade path for carriers with both GSM/UMTS networks and CDMA2000 networks. Because LTE frequencies and bands differ from country to country, only multi-band phones can use LTE in all countries where it is supported.
International Mobile Telecommunications-Advanced are the requirements issued by the ITU Radiocommunication Sector (ITU-R) of the International Telecommunication Union (ITU) in 2008 for what is marketed as 4G mobile phone and Internet access service.
