What is iDEN SIM?
What is iDEN SIM?
iDEN is a TDMA-based digital wireless standard designed to work in special frequencies originally designated for analog Specialized Mobile Radio (SMR) networks. iDEN is used in the U.S. by Nextel and Southern LINC. Newer iDEN phones use a SIM card that is compatible with GSM phones for overseas roaming.
What frequency does LTE run on?
In many markets 4G data (LTE, WiMax) is on 700 MHz, 1700-2100 MHz, 1900MHz and 2500-2700 MHz). Please contact us directly for 4G solutions. In the case of mid to large building repeater systems, single band systems may be adequate.
What frequency is mobile data?
Many GSM phones support three bands (900/1,800/1,900 MHz or 850/1,800/1,900 MHz) or four bands (850/900/1,800/1,900 MHz), and are usually referred to as tri-band and quad-band phones, or world phones; with such a phone one can travel internationally and use the same handset.
Does iDEN still exist?
SouthernLINC Wireless provided iDEN service across the United States until its iDEN network was decommissioned for additional LTE network capacity on 1 April 2019. Telus provided iDEN service across most of Canada until its iDEN network was decommissioned on 29 January 2016.
What 5G bands does tmobile use?
T-Mobile’s 4G LTE network uses bands 4/66 (AWS), 12, 2 (PCS), and 71 (600 mHz). The 4G network acquired from Sprint uses bands 25, 26, and 41. For 5G, T-Mobile is using band 71 (600 MHz) for low-band, band 41 (2,500 Mhz) for mid-band, as well as faster mmWave in select downtown areas.
Who uses iDEN network?
Operators
| Network operator | Country | Frequency (MHz) |
|---|---|---|
| Intelfon | Guatemala | 800 |
| KT Powertel | South Korea | 800 |
| Hot Mobile (Mirs) | Israel | 800 |
| Airpeak | United States | 800 |
What is the iDEN frequency?
Each is slightly different. In the United States, iDEN is allocated 806 MHz – 824 MHz and 851 MHz – 869 MHz . Consolidated Edison in New York City uses iDEN for trunked radio. Their frequencies can be found here .
Is Iden a cellular phone system?
From a U.S. regulatory perspective iDEN networks are not considered cellular phone systems and are licensed to operate on 800MHz SMR frequency allocations (851 – 869 MHz band for towers; 806 – 824 MHz for mobiles). Thus they do not enjoy any of the special protections afforded cellular phone systems transmissions.
What is the bandwidth of the iDEN network?
The entire channel’s operating bandwidth is 25kHz, although the signal itself takes only 18.5 kHz . From a U.S. regulatory perspective iDEN networks are not considered cellular phone systems and are licensed to operate on 800MHz SMR frequency allocations (851 – 869 MHz band for towers; 806 – 824 MHz for mobiles).
What is the transmission rate of Iden?
The transmission format is designed for 25 kHz channel spacing. Data is transmitted using four 16QAM modulated sub-channels; with each sub-channel carrying 4000 symbols / second we end up with a total raw bit rate of 64 kbits/sec. The channel throughput then comes out to very roughly 3 bits/sec/ Hz. The following shows a typical iDEN spectrum:
