Mobile Systems Communications Electrical Engineering

Mobile communications systems include the first and second generation systems like GSM, CDMA, IS-95 etc and third generation (IMT-2000, 3G, UMTS, cdma2000,...). They also include Wireless LANs (IEEE 802.11, HIPERLAN standards), short range communications systems (Bluetooth, IrDA,...) and future broadband systems. Positioning systems (like GPS,...) may also be included in this category.
