Cellular network standards and generation timeline. This is a comparison of standards of wireless networking technologies for devices such as mobile phones.A new generation of cellular standards has appeared approximately every tenth year since 1G systems were introduced in 1979 and the early to mid-1980s.
The iPhone 6s and 6s Plus feature a 12-megapixel (4032×3024 pixels [36]) rear-facing camera, an upgrade from the 8-megapixel (3264×2448) unit on previous models, as well as a 5-megapixel front-facing camera, compared to 1.3 megapixels of the iPhone 5, iPhone 5s, iPhone 6, 6 Plus and iPhone SE.
There are two major differences between LTE-TDD and LTE-FDD: how data is uploaded and downloaded, and what frequency spectra the networks are deployed in. While LTE-FDD uses paired frequencies to upload and download data, [77] LTE-TDD uses a single frequency, alternating between uploading and downloading data through time.
LTE (Long Term Evolution) is commonly marketed as 4G LTE, but it did not initially meet the technical criteria of a 4G wireless service, as specified in the 3GPP Release 8 and 9 document series for LTE Advanced. Given the competitive pressures of WiMAX and its evolution with Advanced new releases, it has become synonymous with 4G. It was first ...
Typical 2G standards include GSM and IS-95 with extensions via GPRS, EDGE and 1xRTT, providing Internet access to users of originally voice centric 2G networks. Both EDGE and 1xRTT are 3G standards, as defined by the ITU , but are usually marketed as 2.9G due to their comparatively low speeds and high delays when compared to true 3G technologies.
In communications, Circuit Switched Data (CSD) (also named GSM data) is the original form of data transmission developed for the time-division multiple access (TDMA)-based mobile phone systems like Global System for Mobile Communications (GSM).
The iPhone 6 was temporarily discontinued on September 7, 2016, and the 6 Plus was permanently discontinued on same date, when Apple announced the iPhone 7 and iPhone 7 Plus, and the iPhone 6 and 6 Plus' spot as the entry-level iPhone was taken by the first-generation iPhone SE. As the iPhone SE has more powerful internal hardware than the ...
