Electromagnetic Compatibility Problems in LTE Mobile Networks 800 MHz Frequency Band

Genotoxicity evaluation of electromagnetic fields generated by 835-MHz mobile phone frequency band.

It is still unclear whether the exposure to electromagnetic fields (EMFs) generated by mobile phone radiation is directly linked to cancer. We examined the biological effects of an EMF at 835 MHz, the most widely used communication frequency band in Korean CDMA mobile phone networks, on bacterial reverse mutation (Ames assay) and DNA stability (in vitro DNA degradation). In the Ames assay, test...

Dynamics of 3GPP LTE uplink: 800 MHz DTT and LTE coexistence

Evaluation of LTE 700 and DVB-T Electromagnetic Compatibility in Adjacent Frequency Bands

The 2012 World Radiocommunication Conference allocated the 694–790 MHz (700 MHz) band for the mobile service on a co-primary basis with other services in Region 1 (Europe, Africa, the Middle East). However, countries of Region 1 will also be able to continue the use of these frequencies for their digital terrestrial television services, if necessary. This allocation will be effective immediatel...

Electromagnetic Compatibility from a Time-Frequency Perspective

In wireless communication, interference between two radio systems may occur when they operate at close frequency bands, sharing the same environment at the same time. Such systems coexist if both of them perform correctly in the presence of the other. To ensure their coexistence, Electromagnetic Compatibility (EMC) is used to specify rules within standardization bodies. According to current EMC...

WHITE PAPER: SHARING BETWEEN LTE SYSTEMS AND AERONAUTICAL MOBILE TELEMETRY (AMT) SYSTEMS IN THE BAND 1435 - 1525 MHz

The band 1 435 – 1 525 MHz is a primary band used for Aeronautical Mobile Telemetry. This noise-limited band is ideal in terms of its propagation characteristics, the maturity of technology for implementing telemetry systems, and the relatively large signal wavelengths. The latter are large enough with respect to the size of aircraft structures to minimize unwanted geometrical effects, such as ...
