OpenBTS (Open Base Transceiver Station) is a software-based GSM access point, allowing standard GSM-compatible mobile phones to be used as SIP endpoints in Voice over IP (VoIP) networks. OpenBTS is open-source software developed and maintained by Range Networks.
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.
Line2 is a Virtual PBX phone service that allows companies to develop and maintain multiple internal phone lines to handle multiple external calls. Line2 uses cloud computing to allow one phone call to go to shared receivers, such as cell phones or fax machines, depending on which is more appropriate. Line2 allows for such transfers without any ...
The Intel XMM modems are a series of 4G LTE, LTE Advanced, LTE Advanced Pro and 5G modems found in many phones, tablets, laptops and wearables (sans 5g-technology) developed by Intel Mobile Communications. [1] Intel Mobile Communications was formed after Intel acquired the Wireless Solutions (WLS) division of Infineon early in 2011 for US$1.4 ...
Each generation of wireless cellular technology has introduced increased bandwidth speeds and network capacity. 4G has speeds of up to 150 Mbit/s download and 50 Mbit/s upload, whereas 3G had a peak speed of 7.2 Mbit/s download and 2 Mbit/s upload.
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.
Motorola Timeport, the first tri-band mobile phone (1999) A dual band 4G+ router. In telecommunications, a multi-band device (including (2) dual-band, (3) tri-band, (4) quad-band and (5) penta-band devices) is a communication device (especially a mobile phone) that supports multiple radio frequency bands. All devices which have more than one ...
While some analogue mobile phones provided a standard RJ11 telephone socket into which a normal landline modem could be plugged, this only provided slow dial-up connections, usually 2.4 kilobit per second (kbit/s) or less. The next generation of phones, known as 2G (for 'second generation'), were digital, and offered faster dial-up speeds of 9. ...
