The main UMTS bands are in bold print. Networks on UMTS-bands 1 and 8 are suitable for global roaming in ITU Regions 1, 2 (some countries) and 3. Networks on UMTS bands 2 and 4 are suitable for roaming in ITU Region 2 (Americas) only. Networks on UMTS band 5 are suitable for roaming in ITU Regions 2 and 3 (single countries).
Also, low mobility users can aggregate multiple channels to get a download throughput of up to 1 Gbit/s [9] Flash-OFDM: Flash-OFDM: Mobile Internet mobility up to 200 mph (350 km/h) Flash-OFDM: 5.3 10.6 15.9: 1.8 3.6 5.4: Mobile range 30 km (18 miles) Extended range 55 km (34 miles) HIPERMAN: HIPERMAN: Mobile Internet: OFDM: 56.9: Wi-Fi: 802.11 ...
The Universal Mobile Telecommunications System (UMTS) is a 3G mobile cellular system for networks based on the GSM standard. Developed and maintained by the 3GPP (3rd Generation Partnership Project), UMTS is a component of the International Telecommunication Union IMT-2000 standard set and compares with the CDMA2000 standard set for networks based on the competing cdmaOne technology.
High Speed Packet Access (HSPA) [1] is an amalgamation of two mobile protocols—High Speed Downlink Packet Access (HSDPA) and High Speed Uplink Packet Access (HSUPA)—that extends and improves the performance of existing 3G mobile telecommunication networks using the WCDMA protocols.
In contrast with GSM base stations, Node B uses WCDMA/TD-SCDMA as the air interface technology. As in all cellular systems, such as UMTS and GSM, the Node B contains radio frequency transmitter(s) and the receiver(s) used to communicate directly with mobile devices, which move freely around it. In this type of cellular network, the mobile ...
Dual-Carrier HSUPA, also known as Dual-Cell HSUPA, is a wireless broadband standard based on HSPA that is defined in 3GPP UMTS release 9. Dual Cell (DC-)HSUPA is the natural evolution of HSPA by means of carrier aggregation in the uplink. [9] UMTS licenses are often issued as 10 or 15 MHz paired spectrum allocations.
For technical details on UMTS and a list of its designated operating frequencies, bands, and their common names, see UMTS frequency bands. Networks on the global UMTS-bands 1 and 8 are suitable for global roaming in ITU Regions 1, 2 (some countries) and 3. Networks on UMTS-bands 2 and 4 allow roaming in ITU Region 2 (Americas) only.
Rev B note: N is the number of 1.25 MHz carriers used. EV-DO is not designed for voice, and requires a fallback to 1xRTT when a voice call is placed or received. Notes: All speeds are theoretical maximums and will vary by a number of factors, including the use of external antennas, distance from the tower and the ground speed (e.g ...
