- Complete set of equipment designed and manufactured by
GOODWIN – from infrastructure equipment (controllers, multiplexers, base
stations, etc.) to subscriber equipment (“GOODWIN TAROUSSA-C” CTA,
subscriber antennas, phones, etc.). The equipment is GAP-compatible;
- Wireless communications for subscriber groups from 50 to
- Connection and service provision for both fixed and local
mobility subscribers in the same system;
- Possibility of connecting remote base stations via existing
cables with the use of G.SHDSL technology (up to 20 km distance);
- High-volume traffic due to the use of 12-channel base
- Long distance wireless access (up to 5 km);
- Voice and data transmission
- Web-based technical servicing and system monitoring
- Low price per subscriber.
By the end of 2001 the GOODWIN BORODINO system will start
supporting data transmission at the rate up to 90kbit/s.
Himachal Futuristic Communications Limited
Established in 1987, Himachal Futuristic Communications has fast emerged as a
leader in the Indian Telecommunication sector. Himachal serve a
large number of customers, which include incumbent operators and new C-LECs.
Dect based Wireless in Local loop
Throughout the world Wireless Local Loop (WLL) is emerging as an alternative
solution to the problems posed by conventional copper access network. WLL
provides quick, reliable and high quality communication services, which are
economically attractive to operators for a fast roll out of the network. COR-DECT HF 1800 WLL is a Wireless Local Loop solution from HFCL which
provides high quality voice, fax, data and Internet services.
Wall Set- IP (WS-IP) The WS-IP is similar to a wallset, with an added V-24
RS-232 serial port for Internet access. A personal computer can be directly
connected to this port without a modem, and Internet access is possible at 35 or
70 Kbps. In addition, simultaneous use of the telephone is possible, making the
WS-IP functionally equivalent to an ISDN terminal. The WS-IP is a fixed
subscriber terminal for the corDECT WLL system that supports both voice and

Midas Communication Technologies Pvt Ltd
Midas was the first company in India to develop indigenous technology based
on DECT standard for WLL access as a last mile connectivity with emphasys on
rural areas where the cost of infrastructure for POTS is quite expensive (in
partnership with Analog Devices Inc, and IIT, Madras).
corDECT is an advanced, field proven, Wireless
Access System developed by Midas Communication Technologies and the Indian
Institute of Technology, Madras, in association with Analog Devices Inc., USA.
corDECT provides a complete wireless access solution for new and expanding
telecommunication networks with seamless integration of both voice and Internet
services. corDECT is a cost-effective Wireless Local Loop (WLL) system in the
world today that provides simultaneous toll-quality voice and 35 or 70 kbps
Internet access to wireless subscribers.
Possibly Tunisia's only telecom manufacturer ?
Based on DECT technology, TAWA has been designed for easy network integration,
with system interfaces to the network on E1 (2.048 Mbps) lines as per ITU-T G703
standard. In one configuration, the TAWA system acts like a switch with its
local loop. Alternatively the TAWA Wireless in Local Loop can be configured as
an Access Network connected to main exchange on ITU-T specified access protocol
TThe basic unit provides service to 1000 subscribers. Multiple TAWA systems can
be connected together using a transit switch. The system has been designed in
such a way that the initial investment for fixed part is very low and most of
the cost is incurred on the subscriber units, thus costs grow only as the
operator signs up subscribers.
RTX specialises in development of advanced wireless communication solutions
across the entire range of wireless technologies (DECT, DPRS, WLL, VoIP, IEEE
802.11a/b/g, 2.4GHz, 5.8GHz, NMT, GSM, GPRS, TD-SCDMA and Bluetooth), focusing
exclusively on making the entire development process rapid, reliable and
Shyam Telecom Ltd, India
- private wallset, public and private systems based on the corDECT technology
developed by IIT Chennai.
In an urban deployment of DECTxs,
subscribers can be served using
microcellular architecture(cell size 300
to 1000 metres). For high density
business centres, multiple Base Stations
can be stacked together.
In the case of suburban areas, medium
sized cells (1km - 3.5kms) can be used.
As suburban areas are prone to the
growth of subscribers in either a
planned or an unplanned manner, such
requirements can be easily dealt with by
adding Base Stations on a as and when
required basis, as the system does not
require any frequency planning.
Remote Semi - Urban/Rural Coverage
For remote semi-urban and rural areas
where the existing demand does not call
for an independent BSC, Base Stations
can be located remotely using an El
interface links. Moreover, with the
extended range Wall Sets, the DECTxs
coverage may be extended to 8-10 kms
from the BS location.
Thin Route, Distributed Rural
Where the operator is required to
provide between 25 to 100 lines for spot
coverage in remote clusters or
townships, DECTxs provides the most
cost-effective solution. In this case
Base Stations can be located at every
20-50 kms using an El drop insert
backbone. DECTxs optimises the immediate
exposure to the operator
Key features of DECTxs
Affordability, low up-front
Very fast & easy deployment
Adaptability to very high & low
Toll quality 32 kbps ADPCM voice
Enhanced privacy/Data, fax, payphone support
Modular & adjustable system
No frequency planning required
Futurability - ISDN, Video-conferencing
Spectrum sharing using DCS to allow a
multi-operator, multiple BSC environment

The DECTlink WLL
system includes integrated support for cordless terminal mobility (CTM) and a radio
network repeater (wireless base station) element.
In addition, the DECTlink compact desktop version offers a solution for small subscriber
