GSM supports both cellular and data, whereas LTE is synonymous with high-speed wireless broadband technology that supports only data . This is why most of the new cell phones use LTE for high-speed internet access and rely on GSM for voice calls.
Read moreDoes Verizon use CDMA or WCDMA?
The Verizon network is a CDMA wireless network.
Read moreWhich carriers are WCDMA?
WCDMA was the 3G technology used in the US by AT&T and T-Mobile .
Read moreIs WCDMA same as CDMA?
The main difference between WCDMA and CDMA is that they are designed to work with different networks. WCDMA is a 3G technology designed to work alongside the 3G GSM network. CDMA, on the other hand, is a 2G technology that is a direct competitor to GSM.
Read moreOFDM sinyali nedir?
OFDM (Orthogonal Frequency Division Multiplexing) – Ortogonal Frekans Bölmeli Çoklama, Yayılı Spektrum’dan daha verimli bir teknolojidir. Bir sinyalin, birçok küçük sinyale bölünerek farklı frekanslarda ve eş zamanlı olarak gönderilmesidir. Yüksek aktarım kapasitesine ihtiyaç duyulan durumlarda kullanılır.
Read moreWhy CDMA Cannot be used for higher bit rates?
CDMA has a soft capacity. The greater the number of codes, the more number of users. However, many codes are used S/I drops and the BER (Bit Error Rate) will increase for all users. CDMA requires a tight power control as it suffers from near-far effect .
Read moreWhy a given bandwidth is used most efficiently in CDMA?
CDMA technology claims that its bandwidth is thirteen times efficient than TDMA and forty times efficient than analog systems. CDMA also have better security and higher data and voice transmission quality because of the spread spectrum technology it uses, which has increased resistance to multipath distortion .
