What is U900 technology?
U900 uses a low-frequency 3G band that delivers outstanding network performance in the areas of 4.5G voice fallback, MBB coverage, and data service experience.
What service is UMTS?
Universal Mobile Telecommunications Service
UMTS (Universal Mobile Telecommunications Service) is a third-generation (3G) broadband, packet-based transmission of text, digitized voice, video, and multimedia at data rates up to 2 megabits per second (Mbps).
How many carriers does GSM 900 have?
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 network refarming?
“Refarming” is the term used for the process governing the. repurposing of frequency bands that have historically been allocated for 2G mobile services (using GSM technology) for new generation of mobile technologies, including both third generation (using UMTS technology) and fourth generation (using LTE technology).
Is UMTS and HSPA the same?
UMTS provides a clear evolutionary path to high-speed packet access (HSPA). HSPA refers to the combination of high-speed downlink packet access (HSDPA) and high-speed uplink packet access (HSUPA). HSPA also boosts capacity in UMTS networks and provides significant latency reductions.
What frequencies are banned?
The manufacture, import, sale, lease, offer for sale or lease, or shipment of wireless microphones or similar devices intended for use in the United States that operate on the 600 MHz service band frequencies (617-652 MHz and 663-698 MHz) is now prohibited. See FCC 15-100, FCC 15-99, FCC 17-95.
What is carriers spacing in GSM 900 and DCS 1800 is?
What Is EDGE (with GSM)?
| P-GSM (GSM 900) | DCS 1800 (GSM 1800) | |
|---|---|---|
| Timeslot Period | 576.9 µs | 576.9 µs |
| Bit Period | 3.692 µs | 3.692 µs |
| Modulation | 0.3 GMSK 3 /8 8PSK | 0.3 GMSK 3 /8 8PSK |
| Channel Spacing | 200 kHz | 200 kHz |
What is frequency refarming in mobile network optimization?
Refarming is a cost-effective way to increase capacity for UMTS/LTE without the need to bid for new spectrum. Compared to networks using the 2100 MHz core-band 3G spectrum, costs can be 50 to 70% less. Operators can provide less densely populated areas with 3G services more cost-effectively.
