The system is intended for both urban and rural areas with high or medium density of population. The main features of the system are as follows

  • 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 480 subscribers;
  • 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 stations;
  • 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.

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 system
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 high-speed Internet.

The TAWA WLL System
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 V5.2.

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 Telecom

DECTxs system 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 Coverage
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 investment
Very fast & easy deployment
Adaptability to very high & low subscriber densities
Toll quality 32 kbps ADPCM voice
Enhanced privacy/Data, fax, payphone support
Modular & adjustable system architecture
No frequency planning required
Futurability - ISDN, Video-conferencing etc.
Spectrum sharing using DCS to allow a multi-operator, multiple BSC environment in the same 20 MHz band
Centralised NMS
