High-Speed Uplink Packet Access (HSUPA) is a 3G mobile telephony protocol in the HSPA family. It is specified and standardized in 3GPP Release 6 to improve the uplink data rate to 5.76 Mbit/s, extend capacity, and reduce latency.
The main benefits for an end user are the following: "5 bar" coverage when there is no existing signal or poor coverage; Higher mobile data capacity, which is important if the end-user makes use of mobile data on their mobile phone (may not be relevant to a large number of subscribers who instead use WiFi where femtocell is located)
The iPhone App Store opened on July 10, 2008. [10] [11] [12] On July 11, the iPhone 3G was released and came pre-loaded with support for App Store. [13] [14] Initially apps could be free or paid, but then in 2009, Apple added the ability to add in-app purchases [15] which quickly became the dominant way to monetize apps, especially games.
A cellular repeater (also known as cell phone signal booster or cell phone signal amplifier) is a type of bi-directional amplifier used to improve cell phone reception. [citation needed] A cellular repeater system commonly consists of a donor antenna that receives and transmits signal from nearby cell towers, coaxial cables, a signal amplifier, and an indoor rebroadcast antenna.
Messenger, [11] also known as Facebook Messenger, is an American proprietary instant messaging service developed by Meta Platforms.Originally developed as Facebook Chat in 2008, the client application of Messenger is currently available on iOS and Android mobile platforms, Windows and macOS desktop platforms, through the Messenger.com web application, and on the standalone Facebook Portal ...
In these networks, at these frequencies, the coverage of WCDMA is considered better than that of the equivalent GSM network. Unlike in GSM, the cells' size is not constant (a phenomenon known as "cell breathing"). This requires a larger number of Node Bs and careful planning in 3G networks.
A flattened all-IP architecture is an option for the network within HSPA+. In this architecture, the base stations connect to the network via IP (often Ethernet providing the transmission), bypassing legacy elements for the user's data connections. This makes the network faster and cheaper to deploy and operate.
UMTS Terrestrial Radio Access Network (UTRAN) is a collective term for the network and equipment that connects mobile handsets to the public telephone network or the Internet. It contains the base stations, which are called Node B 's and Radio Network Controllers (RNCs) [ 1 ] which make up the Universal Mobile Telecommunications System (UMTS ...
