Spectral sharing across 2G-3G systems
The Thrity-Seventh Asilomar Conference on Signals, Systems & Computers, 2003, 20043G schemes with large bandwidth occupancy (e.g. UMTS) are gradually being introduced in response to the growing demand for non-voice services. Meanwhile, 2G systems (e.g., GSM, IS-95) still represent the main source for profit of carriers, and continues to exist for years to come.

Interference analysis: From 2G to 4G
2017 International Conference on Advanced Systems and Electric Technologies (IC_ASET), 2017Unfortunately, better throughputs are continuously requested mobile networks face spectral resource scarcity. Consequently, spectrum resource's use must be optimized for that operators have introduced frequency reuse mechanism. Unfortunately, this mechanism is limited by co-channel interference and adjacent channel interference. An Orthogonal Frequency

The Panel noted that Red 2G is extensively metabolised to aniline. The Panel noted that the current genotoxicity and carcinogenicity databases on Red 2G and its metabolite, aniline, are limited. However both genotoxic and carcinogenic effects have been observed in rodents treated with aniline. The Panel based its evaluation on the conclusions of the EU
