GSM Technology
Roaming Cellular Service in Central America
GSM 850, 1900, 900, 1800

GSM, Global System for Mobile communications, the second generation digital technology originally developed for Europe but which now has in excess of 71 per cent of the world market. Initially developed for operation in the 900MHz band and subsequently modified for the 850, 1800 and 1900MHz bands. GSM originally stood for Groupe Speciale Mobile, a committee which launched the GSM standard. GSM is an open, digital cellular technology used for transmitting mobile voice and data services.

GSM supports data transfer speeds of up to 9.6 kbit/s, allowing the transmission of basic data services such as SMS (Short Message Service). Another major benefit is its international roaming capability, allowing users to access the same services when travelling abroad as at home. This gives consumers seamless and same number connectivity in more than 200 countries. GSM satellite roaming has also extended service access into areas where terrestrial coverage is not available.
