Marconi. 12 miles in 1897 and across the English Channel (21 miles) in 1899. in 1901 Marconi sends the first signal across an ocean. Early Mobile Telephone System Architecture (after WWII) powerful transmitter Single central antenna and coverage (radius 50km) High power consumption of mobile station Very limited capacity

Some of the most common paging, cordless and cellular standards of the world are as below. Paging: The worlds most common paging system is the Post Office Code Standards Advisory Group (POCSAG). This was developed by British Post Office. It supports binary frequency shift keying (FSK) signaling at 512 bps, 1200 bps and 2400bps. The new paging system FLEX and ERMES provides up to 6400bps transmission by using 4-level modulation.

This system uses FSK along with 32 kbps adaptive differential pulse code modulation (ADPCM). DECT system accommodates data and voice system for office and business users

The cellular standards for each of the countries is as follows: U.S: Follows USDC (U.S Digital Cellular) Europe: Almost All of the European countries uses GSM (Global System for Mobile) Japan: uses Pacific Digital Cellular (PDC) standards Germany: uses C-450 cellular standards

Cellular telephone system has developed from first generation analog to second generation digital communications, and finally to the third-generation IMT-2000, (UMTS and CDMA2000).
