The question is not correct. WCDMA is a way of sending information in air (Radio Access Technology) while 4G or 3G a system t of mobile telecommunication. In general, 3G system uses WCDMA 'Radio Access Technology' while 4G uses 'OFDMA' Radio Access Technology. For same thing, 2G uses GERAN Radio Access Technology WCDMA (Wideband Code Division Multiple Access) 및 LTE (Long Term Evolution)는 3GPP (3rd Generation Partnership Project) 릴리스에 해당하는 이동 통신 기술입니다. LTE 표준은 4 세대 (4G)로 간주되는 최신 3GPP 릴리스의 일부이며 WCDMA는 3 세대 (3G) 기술로 지정된 이전 기술입니다 Mobile to base frequency is 1885-2025 MHz, while base to mobile frequency is 2110-2200MHz. But in the US, 1710-1755MHz, and 2110-2155MHz is used. Now, when considering WCDMA, it has frequency bands, and it differs in different places. In Europe and Asia, it has a higher frequency of 2100MHz, while in America, it has a lesser frequency of 1900MHz TD-SCDMA. WCDMA. CDMA2000. Full Form.

SIM cards: Before the advent of 4G LTE, the obvious difference between GSM and CDMA devices were with regards to the SIM card. GSM handsets came with a SIM card slot, while CDMA phones did not A recommendation was made to chsnge to wcdma/gsm mode to get better reception (from lte/wcdma/gsm). Asked if this would have an affect on data speed as i tether frequently and they said no but speedtest.net shows 6 times faster downloads and 10 x upload speeds. But mobile reception improves (-85dbm /full bars). So my questions- • Blind redirection is good alternative when WCDMA and LTE cells are co-located and have well overlapping coverage areas Problems: in case of non-overlaping WCDMA/LTE coverage Problem appears when there is no coverage and theoretically should be, this may cause 'ping-pong effect' LTE WCDMA Moves to a coverage hole 23 LTE is a high-performance interface for cellular mobile communications.

UMTS vs WCDMA 8 Most Valuable Differences You Should Kno

In a nutshell: GSM = 2G, WCDMA = 3G. GSM uses less power and has limited data speed (~144kbps) WCDMA uses more power and has good data speed (~2+Mbps) For auto-switching between 2G/3G modes, use the GSM/WCDMA auto mode (system balances speed vs battery use based on current signal strength). For 2G-only battery saving mode, use GSM only This totally depends upon the geographical region where you are using. Frequency also matters and number of users . GSM has larger coverage area then WCDMA, LTE and WiMAX.But again it is depended on the conditions.In generally the maximum radius can be upto34 km.

If you select LTE/GSM/WCDMA (Auto mode), your mobile phone automatically switches between the two network modes provided you're within range of a 3G or 4G network. If you select GSM only, you can't achieve high data speeds. If you select WCDMA only, your mobile phone can only connect to 3G networks cdma2000、wcdma和td-scdma都是3g的空中接口标准,在接入的标准是不一样。 h/v&jty 其中wcdma采用的是fdd,不需要gps的支持; td-scdma采用的是tdd,需要gps的支持,采用了如智能天线、多用户检测、接力切换等新技术。相对于wcdma来说,td是不支持对高速运动中的用户提供正常的服务 LTE is 4G all IP core based technology. WCDMA is the latest standard on the evolution path of CDMA. It was first launched as 2G technology. 2. Coding Technology - LTE uses OFDM-A. Which stands for Orthogonal Frequency Division Multiple Access. CDMA uses unique spreading codes to spread the baseband data before transmission. 3. CDMA and LTE. The system architectures between LTE and WiMAX network will be shown. In addition, a comparison of the system architecture and the air interface of these two networks will be discussed. The paper further concludes with discussion of these two aspects and gives the short look into the future 4G evolution from WCDMA with HSPA/HSPA+ features.
