	About LMDS
		LMDS, as a licensed spectrum, has distinct advantages over unlicensed systems as it is much less susceptible to interference and offers far greater bandwidth.
		LMDS signal strength is greatly reduced by the presence of moisture.
		What all this means is that LMDS is an extremely cost effective and easy way to bring broadband wireless access to any building that is not fed by fiber or suffers from the last mile connectivity problem.

	LMDS: Broadband Out of Thin Air
		LMDS may be the key to delivering broadband multimedia applications to millions of customers worldwide over the air.
		Recognizing LMDS as a means of beaming data and voice over short distances to a switching office, McCaw's Nextlink, in mid-1999, paid nearly $700 million to purchase LMDS licences and the spectrum with aim to provide fixed wireless coverage for 95 percent of the US population.
		Initially, LMDS operators target SMEs in densely populated, urban areas because of the technological requirement of LoS between the hub base station and the buildings served and the signal propagation range of one to three kilometers.

	eclectic content : article - LMDS
		LMDS is considered a proven technology, because it’s been tested by the U.S. military and corporate pioneers such as SpeedUs.com, formerly CellularVision USA, in New York.
		Basically, LMDS is a wireless service transmitting fixed, broadband microwave signals (actually millimeter-wave signals) in the 28 GHz band of the spectrum within small cells roughly three miles in diameter.
		And since LMDS can be used for two-way transmission through the use of low-powered residential transceivers, it is seen as a way to provide interactive services without the installation and maintenance expense encountered on fiber or coax lines.

	Wave Report \| LMDS Tutorial (Site not responding. Last check: 2007-10-10)
		A past tutorial on fixed wireless technology defined local multipoint distribution service (LMDS) as spectrum in the 27.5GHz to 28.35 GHz, 29.1GHz to 29.25 GHz, and 31GHz to 31.3 GHz bands, which is used for high-bandwidth, point-to-multipoint applications.
		LMDS systems shift the cost to the CPE, which means the operator only spends money when a revenue-paying customer signs on.
		LMDS signals are affected by moisture, which could result in "rain fade," or the disruption of signals as a result of heavy rain.

	What is LMDS?
		Data-transport security is accomplished under LMDS by encrypting traffic flows between the broadband wireless modem and the WMTS (Wireless Modem Termination System) located in the base station of the providers network using Triple DES.
		LMDS and MMDS wireless modems utilize the DOCSIS+ key-management protocol to obtain authorization and traffic encryption material from a WMTS, and to support periodic reauthorization and key refresh.
		LMDS may be obsoleted by the newer 802.16 WiMAX standard which is due in 2004.

		LMDS aparece como una prometedora tecnología de gran valor estratégico en el marco de las comunicaciones inalámbricas de banda ancha.
		En LMDS se utiliza la táctica contraria: como el ancho de banda espectral es un recurso menos escaso (se dispone de 1, 2 o 3 GHz), se utilizan sistemas de modulación en banda ancha para transmitir la señal (por ejemplo, modulación FM).
		El LMDS (Local Multipoint Distribution System) es un sistema de comunicación de punto a multipunto que utiliza ondas radioeléctricas a altas frecuencias, en torno a 28 ó 40 GHz1, en las que existen bandas de frecuencia de unos 2 GHz con atenuación mínima (conocidas como "ventanas espectrales") ante los agentes atmosféricos.

	Local Multipoint Distribution Service - Wikipedia, the free encyclopedia
		LMDS is a point-to-multipoint service, hence is typically deployed for access by multiple parties.
		Links up to 5 miles (8 km) from the base station are possible, but distance is typically limited to 1.5 miles by rain fade because heavy rain can severely attenuate signal levels.
		Point-to-point systems are also capable of using the LMDS frequencies and can reach slightly farther distances due to increased antenna gain.

		The U.S. LMDS auction in 1998, where a large number of LMDS licenses were sold to a number of companies, triggered efforts to develop a new generation of LMDS systems to compete with wireline technologies like fiber, coaxial cable and xDSL.
		For this new generation of LMDS systems to compete with other technologies, the operators need to find out which markets that are most likely to embrace LMDS as a "last mile" technology, and which services different market segments should be offered.
		These standards are developed mainly for the first generation of LMDS systems, but are nevertheless of interest as many people in the LMDS industry prefer to reuse the same solutions, even though they are not optimal for the new generation of LMDS systems.

	LMDS - a Whatis.com definition
		LMDS is an alternative to installing optical fiber all the way to the user or to adapting cable TV for broadband Internet service.
		Because LMDS requires a more expensive and possibly larger transceiver than can conveniently be packaged in a handheld device, LMDS is not viewed as a replacement for or alternative to mobile wireless technologies such as cellular and GSM.
		In general, LMDS is for fixed locations and offers higher data rates; cellular digital such as GSM is for mobile users at lower data rates (although these will increase with technologies leading up to UMTS).

	LMDS formula awaits approval - 7/1/1996 - CED - CA6261784 (Site not responding. Last check: 2007-10-10)
		LMDS' higher frequency (in the 28 GHz range) and its relatively massive available bandwidth (1000 MHz) makes it the two-way, interactive darling that MMDS (in the 2.5 GHz range with less than 200 MHz of bandwidth) is not (see Figure 1).
		The commercial viability of LMDS was first demonstrated in 1991 when the FCC opened the 27.5 – 30 GHz Ka-band frequency (commonly referred to as the 28 GHz band) up for broadband telecommunications applications.
		LMDS proponents wanted official recognition and dedicated spectrum to do their thing in the 28 GHz band.

	Reply Comment of the Staff of the Bureau of Economics, FTC
		LMDS uses super-high frequency microwaves to send and receive two-way signals in an area, or cell, approximately 3 to 6 miles in diameter.
		Because LMDS has the potential to compete both with LECs and cable systems, the FCC is considering whether to adopt eligibility or use restrictions on LECs and cable operators seeking to acquire LMDS spectrum licenses within their geographic service areas (4th NPRM, ¶ 1).
		Because the FCC has contemplated restrictions only on LMDS license acquisition in overlapping geographic markets, the only scope economies relevant to assessing the costs of such policy are those that require joint operation of a local exchange (or cable system) and the overlapping LMDS.

	CC 92-297, 08-23-96 LMDS Letter
		Although LMDS was viewed initially as merely an alternative multichannel video programming service, it has become clear that LMDS licensees will also be able to offer local exchange telephone service, internet access, and other broadband services.
		The Commission has proposed to grant only one LMDS license in each geographic license area, known as a Basic Trading Area (BTA), which raises the question whether LECs and cable operators should be eligible to bid for and hold an LMDS license within their current service areas.
		While incumbents may have a strong incentive to act anticompetitively in using LMDS spectrum in their own service areas, their ownership of a license could promote consumers' interests where they are the highest-valued users of LMDS spectrum.

		On the service-provider side of an LMDS system, co-located with the antenna, is a digital basestation that carries out the lower layer functions required to communicate over the air.
		LMDS systems suffer from a high attenuation of signals at 10 GHz and above, from severe channel deterioration in the presence of rain and snow, and from limited inter-symbol interference (ISI) tolerance because of the high data rate.
		LMDS systems must therefore employ strong error correction and equalization schemes to be effective.
