What is cellular RF?
What is cellular RF?
Cell phones emit low levels of non-ionizing radiation while in use. The type of radiation emitted by cell phones is also referred to as radio frequency (RF) energy.
What bands does consumer cellular use?
Consumer Cellular is a post-paid mobile virtual network operator founded in 1995 that uses GSM 850 MHz & PCS 1900 MHz for Voice and 3G Data. Its 4G devices most often use AT’s LTE Band to provide 4G LTE data speeds.
Is RF radiation harmful?
Exposure to very high RF intensities can result in heating of biological tissue and an increase in body temperature. Tissue damage in humans could occur during exposure to high RF levels because of the body’s inability to cope with or dissipate the excessive heat that could be generated.
What RF frequencies are harmful to humans?
Despite the advent of numerous additional research studies on RF fields and health, the only established adverse health effects associated with RF field exposures in the frequency range from 3 kHz to 300 GHz relate to the occurrence of tissue heating and nerve stimulation (NS) from short-term (acute) exposures.
What band is 5G?
Today, a majority of commercial 5G networks rely on spectrum in the 3.5 GHz range (3.3 GHz-4.2 GHz). This momentum makes it vital that regulators assign as much contiguous 5G spectrum as possible in the range.
What 4G LTE bands does Consumer Cellular use?
United States Service Providers
Carrier’s Name | 3G Frequencies / Wavelengths | 4G, LTE, 5G frequencies / Wavelengths |
---|---|---|
Consumer Cellular | 3G : 850 MHz Cellular, Band 5 (GSM/ GPRS/ EDGE). 1900 MHz PCS, Band 2 (GSM/ GPRS/ EDGE). | 4G : 1700/ 2100 MHz AWS, Band 4 (LTE). |
Who is the carrier for Consumer Cellular?
Consumer Cellular uses two networks—AT and T-Mobile. That should give you adequate coverage across the US and possibly even zippy 4G LTE or 5G speeds.
Which LTE band is the best?
Far more LTE networks have been deployed at 1800 MHz (band 3) than in any other frequency band. Band 3 is now widely used throughout Europe, APAC, MEA and is also deployed in selected countries in South America. It has become a core band for LTE deployments.
Which is better 4G or LTE?
In laymans terms, the difference between 4G and LTE is that 4G is faster than LTE. The reason for this is that 4G meets the technical standards designated for it whereas LTE data transfer speed standard is merely a stopgap measure standard devised until actual 4G speed is realized.
What are the cellular bands?
They divide the RF spectrum into multiple ranges of frequencies, known as bands. Within the RF spectrum, the cellular bands are roughly located between 600 MHz and 39 GHz. Keep in mind: frequency bands represent a range of frequencies, not a single cellular frequency. For example, the 700 MHz frequency band ranges from 699 MHz to 798 MHz.
What frequency bands are used for cell phone service?
To account for new technologies, the FCC opened the 1900 MHz band and named it the Personal Communications Service (PCS). For a while, AMPS and PCS were the only cellular frequency bands in use. Years passed, and smartphones debuted.
How are radio frequencies reassigned in a cellular network?
As cellular mobile telephone technology has evolved over time, periodically bands of frequencies are reassigned from other radio services. Companies wishing to provide cellular services in a geographic region compete for the right to license radio spectrum in spectrum auctions.
What is the 700 MHz band for cellular service?
Four years later, cellular service opened up in the lower 700 MHz bands 12 and 17 and the upper 700 MHz band 13. These longer-range frequencies in the Seven-hundred MHz ( SMH) range provide cellular coverage in rural and remote areas as part of 4G’s Long Term Evolution ( LTE) plan.
