What is the maximum data rate supported by UMTS network?
Maximum data rates of 2 Mbit/s, typically 384 kbit/s per user, became possible as a result. UMTS/HSPA+, a further development of UMTS, allows, theoretically and under optimal propagation conditions, transmission rates of up to 21 Mbit/s per user with a single channel (5 MHz bandwidth).
Is UMTS a 2G or 3G?
UMTS stands for Universal Mobile Telecommunication System, and LTE stands for Long Term Evolution. GSM is a second-generation technology (2G), UMTS is a third-generation technology (3G), and LTE is a fourth-generation technology (4G).
What is the bandwidth of GSM network?
GSM-900 and GSM-1800 are used in most of the world. GSM-900 uses 890 – 915 MHz to send information from the Mobile Station to the Base Transceiver Station (BTS) (This is the “uplink”) and 935 – 960 MHz for the other direction (downlink), providing 124 RF channels spaced at 200 kHz. Duplex spacing of 45 MHz is used.
What is the range of channel bandwidth LTE can support?
LTE RF Conformance Page 12 2. LTE Physical Layer • LTE physical layer (FDD/TDD) supports bandwidth from 1.4 to 20 MHz. Current LTE supports a subset of 6 different system bandwidths.
What network is UMTS?
Universal Mobile Telecommunications System
The Universal Mobile Telecommunications System (UMTS) is a third generation mobile cellular system for networks based on the GSM standard.
Is WCDMA and UMTS same?
Key Differences between UMTS vs WCDMA Though both are developed for mobile communications in the 3G network, UMTS is developed for 3G networks alone, whereas WCDMA is developed for 3G networks and 3G+ networks. When we consider WCDMA, it is based on GSM to make the coverage for 2G and 3G.
What is the difference between UMTS and LTE?
The main difference is that UMTS supports 3G and LTE can support 4G communication with better speeds compared to the UMTS. LTE supports the flexible bandwidth with the range in 1.4 to 20 Mhz while UMTS uses the static fixed carrier of frequency 5MHz.
What is the difference between GSM and LTE?
LTE is used to provide high-speed data services as well as voice call services whereas, GSM is used to provide low-speed data services and voice call services. LTE uses the fourth-generation (4G) communication standard whereas GSM uses both the second-generation(2G) as well as third-generation(3G).
What is system bandwidth in LTE?
The supported LTE system bandwidths are {1.4, 3, 5, 10, 15, 20} MHz including guard bands. Discounting the guard bands, the maximum bandwidth that can be scheduled in the largest system bandwidth is 100 PRBs or 18 MHz. Ordinary LTE devices support transmission and reception spanning the full system bandwidth.
