xDSL

xDSL is the name coined for the family of digital subscriber line technologies ranging from HDSL through to VDSL. · ADSL (Asymmetric Digital Subscriber Line): ADSL is a modem technology that transforms ordinary phone lines (also known as "twisted copper pairs") into high-speed digital lines for ultra-fast Internet access. ADSL provides speeds of up to 8 Mbps downstream (to the user) and up to 1 Mbps upstream, depending on line length, loop and line conditions. · HDSL (High Data Rate Digital Subscribe Line): Modems on either end of one or more twisted pair wires that deliver T1 or E1 speeds. At present T1 requires two lines and E1 requires three. · SDSL (Symmetric Digital Subscriber Line): HDSL plus POTS (Plain Old Telephone Service) over a single telephone line. It is important to distinguish, however, as SDSL operates over POTS and is suitable for symmetric services to the residences of individual customers. · VDSL (Very High Data Rate Digital Subscriber Line): Modem for twisted-pair access, operating at data rates of 12.9-52.8 Mbps, with a corresponding maximum reach ranging from 4500 feet to 1000 feet of 24 gauge twisted pairs.

Short Range Devices

Radio equipment operating in the frequency range 9 kHz-25 GHz with power up to a maximum 500 mW are commonly called Sort-Range Devices. Short Range Devices (SRD) require no license, they are popular for consumer applications and in recent years the market for such devices has grown rapidly. It is expected that this growth will continue at an accelerated pace as an increasing number of consumer devices incorporate wireless capabilities for reasons of mobility or remote control.Typical examples for such products include:· Door chimes · Security and alarm systems · Garage door openers · Radio microphones · Cordless loudspeakers, headphones · Model controls · Wireless keyboards, mice Essential requirements for short-range devices are laid down in article 3 of the R&TTE Directive and cover safety, EMC and the effective use of radio spectrum. Procedures for establishing EMC and safety standards make use of conformity assessment procedures in the existing EMC Directive 89/336/EEC and Low Voltage Directive 73/23/EEC. Harmonized standards under both directives can be used for conformity assessment procedures and declarations of conformity.Conformity assessment procedures related to the use of radio spectrum (transmitters only) are laid down in article 10 of the R&TTE Directive. For the time being the R&TTE Directive does not harmonize standards covering radio spectrum requirements. It is expected that harmonized standards will be published in early 2001. Until then the manufacturer or importer must submit technical documentation for review to a Notified Body.Although essential requirements are now harmonized across Europe, the allocation of frequencies remains within the competence of Member States. This means that frequencies allocated for certain radio services differ between Member States. Consequently, though radio equipment can be legally placed on the market in any Member State, it can not necessarily be used. The manufacturer or his authorized representative is obliged to notify the spectrum management authority of the state where he intends to place radio equipment.

Mobile Communications

GSM, which stands for Global System for Mobile Communications, is a digital cellular radio network operating in over 200 countries worldwide. It provides almost complete coverage in Western Europe, and growing coverage in the Americas, Asia and elsewhere. GSM networks presently operate on three different frequency ranges. These are:

· GSM 900 (also called GSM) - operates on the 900 MHz frequency range and is the most common in Europe and internationally.

· GSM 1800 (also called PCN and DCS 1800) - operates on the 1800 MHz frequency range and is found in a rapidly-increasing number of countries including France, Germany, Switzerland, the UK, and Russia.

· GSM 1900 (also called PCS, PCS 1900, and DCS 1900) - the only frequency used in the United States and Canada for GSM. Current

GSM approval requirements are detailed below:

Pan-Europe

GSM terminal equipment is covered by Annex IV of the R&TTE Directive (1999/5/EC). All applicable Harmonized Standards on GSM 900, GSM 1800 and GSM 900/1800 have been published in the European official journal.Currently there is no harmonized EMC standard for GSM terminal equipment. To declare EMC conformity, the generic EMC standard for other devices EN 50081/ 50082 can be used. However, in order to fulfil EMC requirements, the non-harmonized standard ETS 300 342-1 is recommended. To declare safety conformity, EN 60950 applies.The GSM Certification Forum (GCF) has been developed in co-operation and through partnership with the GSM Association, representing GSM operators and terminal manufacturers, to ensure the interoperability of GSM terminals globally. The GSM Certification Forum program contains technical requirements on GSM 900/1800 terminals.

North America

For regulatory type approval in North America, FCC regulations including SAR and probably UL regulations concerning GSM have to be taken account of.Alternatively, a PCS-1900 mobile manufacturer will be required to comply with the GSM 1900 Type Certification Program, which is organized by GSM operators in North America. The program is maintained by PTCRB (PCS 1900 Type Certification Review Board).
