In 3G, the most prevalent technology was UMTS with CDMA-2000 in close contention. All radio access technologies have to solve the same problems: to divide the finite RF spectrum among multiple users as efficiently as possible. GSM uses TDMA and FDMA for user and cell separation. UMTS, IS-95 and CDMA-2000 use CDMA.
Since at least the 1990s, scientists have researched whether the now-ubiquitous radiation associated with mobile phone antennas or cell phone towers is affecting human health. [1] Mobile phone networks use various bands of RF radiation, some of which overlap with the microwave range. Other digital wireless systems, such as data communication ...
The Wave is a slim touchscreen phone powered by "Scorpion" CPU, which includes 1.4 GHz ARM Cortex-8 [2] CPU and a powerful graphics engine, "Super LCD" screen and 720p high-definition video capture capabilities. Shortage of Super AMOLED screens was one of the primary reasons for the release of this model.
Concerns over Chinese involvement in 5G wireless networks stem from allegations that cellular network equipment sourced from Chinese vendors may contain backdoors enabling surveillance by the Chinese government (as part of its intelligence activity internationally) and Chinese laws, such as the Cybersecurity Law of the People's Republic of China, which compel companies and individuals to ...

In radio, multiple-input and multiple-output ( MIMO) ( / ˈmaɪmoʊ, ˈmiːmoʊ /) is a method for multiplying the capacity of a radio link using multiple transmission and receiving antennas to exploit multipath propagation. [ 1][ 2] MIMO has become an essential element of wireless communication standards including IEEE 802.11n (Wi-Fi 4), IEEE ...
