Wikipedia defines GPRS as a “best effort” service and “a packet oriented mobile data service on the 2G and 3G cellular communication system’s global system for mobile communications (GSM).” Depending on who you believe in 2G systems GPRS provides data rates of 35–171Kilobits per second (Kbps). 2G cellular technology combined with
The introduction of GSM into North America meant further adaptation to the 800 and 1900 MHz bands. Over the years, the versatility of GSM has resulted in the specifications being adapted to many more frequency bands to meet niche markets. A full list can be found in 3GPP TS 45.005. GSM has a channel spacing of 200kHz and was designed
GSM World Coverage Map and GSM Country List. most popular standard for mobile phones in the world. GSM 900 / GSM 1800 MHz are used in most parts of the world: Europe, Asia, Australia, Middle East, Africa. GSM 850 / GSM 1900 MHz are used in the United States, Canada, Mexico and most countries of S. America.
And the demand for 4G, 5G, LTE-M, and NB-IoT will only increase in the years to come. Most 2G networks based on GSM use 850–1800 MHz or 900–1900 MHz bands. And 3G networks use bands between 850–1900 MHz or 900–2100 MHz. More advanced cellular technologies could use these same bands to provide higher data throughput and more valuable
share the same key with A5/1 in GSM, our attack can be leveraged into attacks against any GSM 2G/3G network eventually. This paper is organized as follows. A brief description of the A5/1 stream cipher and the GSM encryption scheme is presented in Section 2. Some basic de nitions and preliminaries of the fast near collision attack relevant to our
Third-generation cellular technology, otherwise known as 3G builds on the advancement of the 2.5G networks to support higher throughput and speeds of data transfer. This enables 3G network operators to deliver a wider range of services including: Mobile internet access. Voice over internet protocol. Video calls.
