The data rate is using 14.4kbps. The Frequency for it is 200Khz and supported up to 8 users at a time.]]> 2020-05-12 04:44:00 UTC https://padlet.com/fongteng95/yh5h98ogpkhkbazd/wish/566545725 3G (Third Generation) fongteng95 https://padlet.com/fongteng95/yh5h98ogpkhkbazd/wish/566551224 Third Generation (3G) is using new technology such as 3GPP2, CDMA, CDMA -EVDO for high bandwidth and high data rates. in CDMA devices transmit voice as well as data and multimedia streams.]]> 2020-05-12 04:51:04 UTC https://padlet.com/fongteng95/yh5h98ogpkhkbazd/wish/566551224 4G (Fourth Generation) fongteng95 https://padlet.com/fongteng95/yh5h98ogpkhkbazd/wish/566554511 Fourth Generation (4G) is broadband cellular network technology after succeeding 3G 4G facilitates even higher data rates than 3G and supports streaming data for video. 4G enables multimedia newspaper, high-resolution mobile TV, Internet protocol (IP) telephony, and data rates of up to 100 Mbps.]]> 2020-05-12 04:55:02 UTC https://padlet.com/fongteng95/yh5h98ogpkhkbazd/wish/566554511 5G (Fifth Generation) fongteng95 https://padlet.com/fongteng95/yh5h98ogpkhkbazd/wish/566556734 Fifth Generation (5G) began deploying worlwide in 2019. The theoretical speed for 5G is 10Gbps and real world speed is 1Gbps. The latency for 5G is below 30 milliseconds at speed of nearly 1Gbps, with 5G low latency it is possible that we can use AR or VR application realtime with promises. In 5G networks, the maximum theoretical supported devices is a million devices per square kilometer, while 4G supports only up to 100,000 devices per square kilometer. ]]> 2020-05-12 04:57:39 UTC https://padlet.com/fongteng95/yh5h98ogpkhkbazd/wish/566556734
