LMDS (Local Multipoint Distribution Service)-TACS
Local Multipoint Distribution Service
(LMDS) is a broadband wireless access technology originally designed
for digital television transmission (DTV). It was conceived as a
fixed wireless, point-to-multipoint technology for utilization in
the last mile. LMDS commonly operates on microwave frequencies
across the 26 GHz and 29 GHz bands. In the United States,
frequencies from 31.0 through 31.3 GHz are also considered LMDS
frequencies.
Throughput capacity and reliable distance of the link depends on
common radio link constraints and the modulation method used -
either phase-shift keying or amplitude modulation. Distance is
typically limited to about 1.5 miles (2.4 km) due to rain fade
attenuation constraints. Deployment links of up to 5 miles (8 km)
from the base station are possible in some circumstances such as in
point-to-point systems that can reach slightly farther distances due
to increased antenna gain.
There was interest in LMDS in the late
1990s and it became known in some circles as "wireless cable" for
its potential to compete with cable companies for provision of
broadband television to the home.
Despite its early potential and the
hype that surrounded the technology, LMDS was slow to find
commercial traction. Many equipment and technology vendors simply
abandoned their LMDS product portfolios.
Industry observers believe that the window for LMDS has closed with
newer technologies replacing it. Major telecommunications companies
have been aggressive about deploying alternative technologies such
as IPTV and fiber to the premises, also called "fiber optics".
Moreover, LMDS has been surpassed in both technological and
commercial potential by the LTE, WiMax and 5G NR standards (wiki).
