Mobile Phone
A mobile phone, known as a cell phone in North America, is a portable telephone that can make and receive calls over a radio frequency link while the user is moving within a telephone service area. The radio frequency link establishes a connection to the switching systems of a mobile phone operator, which provides access to the public switched telephone network (PSTN). Modern mobile telephone services use a cellular network architecture, and, therefore, mobile telephones are called cellular telephones or cell phones, in North America. In addition to telephony, 2000s-era mobile phones support a variety of other services, such as text messaging, MMS, email, Internet

access, short-range wireless communications (infrared, Bluetooth), business applications, video games, and digital photography

MTD (mobile Network)
MTD (Swedish abbreviation for Mobiltelefonisystem D, or Mobile telephony system D) was a manual mobile phone system for the 450 MHz frequency band. It was introduced in 1971 in Sweden, and lasted until 1987, when it was made obsolete by the NMT automatic service. The MTD network had 20,000 users at its peak, with 700 people employed as phone operators. MTD was also implemented in Denmark

(from 1976), which allowed roaming within the Scandinavian countries. MTA[edit] In Sweden, the first mobile phone system was MTA (for Mobiltelefonisystem A), which was introduced in 1956, and lasted until 1967. It was a 160 MHz system available in Stockholm

(IS-2000) standard that supports high data rates and can be deployed alongside a wireless carrier's voice services. It uses advanced multiplexing techniques including code division multiple access (CDMA) as well as time division multiplexing (TDM) to maximize throughput. It is a part of the CDMA2000

1G
1G refers to the first generation of wireless cellular technology (mobile telecommunications). These are the analog telecommunications standards that were introduced in the 1980s and continued until being replaced by 2G digital telecommunications. The main difference between the two mobile cellular systems (1G and 2G), is that the radio signals used by 1G networks are analog, while 2G networks are digital. Although both systems use digital signaling to connect the radio towers (which listen to the handsets) to the rest of the telephone system, the voice itself during a call is encoded to digital signals in 2G whereas 1G is only modulated to higher frequency, typically 150 MHz and up

Mobile Telephone System
The Mobile Telephone

Service (MTS) was a pre-cellular VHF radio system that linked to the Public Switched Telephone Network (PSTN). MTS was the radiotelephone equivalent of land dial phone service. The Mobile Telephone
Telephone
Service was one of the earliest mobile telephone standards. It was operator assisted in both directions, meaning that if one were called from a land line the call would be routed to a mobile operator, who would route it to one's phone. Similarly, to make an outbound call one had to go through the mobile operator, who would ask for the mobile number and the number to be called, and would then place the call. This service originated with the Bell System, and was first used in St. Louis on June 17, 1946

Improved Mobile Telephone Service
The Improved Mobile Telephone Service (IMTS) was a pre-cellular VHF/UHF radio system that links to the PSTN. IMTS was the radiotelephone equivalent of land dial phone service. It was introduced in 1964 as a replacement to Mobile Telephone Service or MTS and improved on most MTS systems by offering direct-dial rather than connections through a live operator.Contents1 Technical Information1.1 Terminal 1.2 Base station 1.3 Frequencies2 Limitations 3 See also 4 References 5 External linksTechnical Information[edit]This section needs additional citations for verification.

Olt (mobile Network)
OLT (Norwegian for Offentlig Landmobil Telefoni, Public Land Mobile Telephony), was the first land mobile telephone network in Norway. It was established December 1, 1966, and continued until it was obsoleted by NMT in 1990. In 1981, there were 30,000 mobile subscribers, which at the time made this network the largest in the world. The network operated in the 160 MHz VHF

band, using frequency modulation (FM) on 160-162 MHz for the mobile unit, and 168-170 MHz for the base station

Autotel
Autotel (also called PALM, or Public Automated Land Mobile) is a radiotelephone service which was the "missing link" between earlier MTS/IMTS and later cellular telephone services. It used digital signaling for supervisory messages (call setup, ringing, channel assignment, etc.), except the voice channel was analog (as was the original NMT and AMPS cellular systems). This system was not cellular, as it used existent high-power (35 watt) VHF channels

Autoradiopuhelin
ARP (Autoradiopuhelin, "car radio phone") was the first commercially operated public mobile phone network in Finland. The technology is zero-generation (0G), since although it had cells, moving between them was not seamless. The network was proposed in 1968 and building began in 1969. It was launched in 1971, and reached 100% geographic coverage in 1978 with 140 base stations. The ARP network was closed at the end of 2000 along with NMT-900. ARP was a success and reached great popularity (10,800 users in the year 1977, with a peak of 35,560 in 1986), but the service eventually became too congested and was gradually replaced by the more modern NMT technology. However, ARP was the only mobile phone network with 100% percent coverage for some time thereafter, and it remained popular in many special user groups. ARP operated on 150 MHz frequency (80 channels on 147.9 - 154.875 MHz band). Transmission power ranged from 1 watt to 5 watts
