Data transmission and data reception or, more broadly, data communication or digital communications is the transfer and reception of data in the form of a digital bitstream or a digitized analog signal over a point-to-point or point-to-multipoint communication channel. Examples of such channels are copper wires, optical fibers, wireless communication using radio spectrum, storage media and computer buses. The data are represented as an electromagnetic signal, such as an electrical voltage, radiowave, microwave, or infrared signal.
Analog transmission is a method of conveying voice, data, image, signal or video information using a continuous signal which varies in amplitude, phase, or some other property in proportion to that of a variable. The messages are either represented by a sequence of pulses by means of a line code (baseband transmission), or by a limited set of continuously varying waveforms (passband transmission), using a digital modulation method. The passband modulation and corresponding demodulation is carried out by modem equipment. According to the most common definition of digital signal, both baseband and passband signals representing bit-streams are considered as digital transmission, while an alternative definition only considers the baseband signal as digital, and passband transmission of digital data as a form of digital-to-analog conversion.
Data transmitted may be digital messages originating from a data source, for example, a computer or a keyboard. It may also be an analog signal such as a phone call or a video signal, digitized into a bit-stream, for example, using pulse-code modulation or more advanced source coding schemes. This source coding and decoding is carried out by codec equipment.
Pa help naman diko alam kung akin lang may problema. Medyo mabagal tapos di stable yung signal ng data ko pero sa ibang phone okay naman malakas hatak ano po possible way para ma fix to
btw. naka ilang reset nako factory reset tapos from global rom lumipat ako sa eu rom same parin
Need help po, paano po ma solve tung slow Dito data signal ko. Hanggang 2mbps lang yung max speed ng internet ko kahit malapit lang yung Dito tower di to saamin.
Pa help po kung ano ba gawin nito ang hina ng signal sa phone ko eh hndi naman sa sim ang problem tpos 4g naman sya pero biglang nawawala signal any tips po kung paano palakasin to?
Thqnkyou

Good day. As background: boarder (won't stay long kaya iniiwasan ko magpakabit ng linya dahil sa lock-in period) and primarily using mobile data for my daily usage, tas pinagho-hotspot ko nalang sa laptop ko. Pretty useable speeds naman inaabot ng Globe signal (around 20 Mbps).
Problem started...
blocked po ba pag ayaw lumabas ng data signal? kanina ok pa nman 5G pa nga signal, ngayon ayaw na lumabas data signal kahit ilagay ko sa 2G, 3G, 4G. malakas nman signal sa area ko.
Tulungan nyo naman po ako dito sa Globe ko po.
Globe LTE sya ung bagong sim. ang problema ko pag nasa Sony Xperia ko sya at default apn meron sya data signal... pero pag ilalagay ko sya sa LG K10 at naka default apn wala naman syang Data signal... ano po ba ang dapat kung gawin dito?
Tulungan...
