. Radio Communication

The dream and vision is lived everyday at Tek Signals, with the evolution of the systems branded every day as brand new-but the scenario is different altogether at Tek Signals, the moment some tech news hit the stands, the personnel are busy working and have researched a commendable amount on the technicalities of the telecommunications. Trust building is not easy until it is a convention and every professional aspect is a convention at Tek Signals.

Following are the briefly described technologies which have been under special operations and supervision, nothing is deemed as perfect until the new version comes in, but the services are never compromised.

Wireless Local Loop
- Eliminate the need for complex cell and frequency planning
- TDMA/SDMA:4 ports per radio frequency
- Up to 9.6 Kbps (single slot) up to 56 Kbps on the DVSU (double slots with V5.2 I/F
and V90 modem)
- Focuses radio signals on an individual user, establishing a "virtual wire" connection with the subscriber
- Combines an Adaptive Array Antenna, Spatial Channel processing and Wide-band radios.


Single Channel Radio
- Provides one dedicated telephone channel in the VHF and UHF frequency bands
- Replacing wireline circuits with full duplex, ITU-T standard radio telephone connections
- Field adjustable output power. Simultaneous data and telephone communication
- Voice secrecy facility selectable from front panel.
- Use of Digital Signal Processing (DSP) technology


Digital Multi-Channel Radio
- Feature-rich interface (RSSI, analogue and digital base band)
- Data rates up to 5 kbps for standard module
- Used In-building environmental monitoring and control
- Usable range over 500m , Fully screened. Low profile.
- Serial configuration by inverted RS232 at 3V CMOS level


Broadband Wireless Access, TV and Internet
- Internet Access Eliminates Dial-up Hassles..
- Can be Shared by Multiple Computers.
- Simultaneously broadcasts multi-channel analog and/or digital TV and provides two-way IP connectivity for High-Speed Internet Access and other IP high performance applications
- Combine two services through a single base station infrastructure for maximum revenue at minimum capital deployment cost


Vioce over IP, Internet Wireless Solution
- Digital Satellite Modem, Satellite Modem Satellite, Burst Modem Band Receiver/Demodulator, Satellite Modem (4.8 kbps to 9.312 Mbps)
- Fully Accessible System Topology (FAST)
- Closed Network Capability
- 2.4 kbps to 4.375 Mbps
- Burst Mode Operation: 19.2 kbps and 57.6 kbps


Microwave Links
- Frequency bands available from 13 to 38 GHz
- Robust design to give high reliability.
- Embedded feature rich SNMP
- High quality and consistency
- Transport of one or two E1 tributaries in a compact, all-outdoor solution


Auxiliary Equipments
- Power Dividers, Directional Couplers, Fixed Attenuators, RF Terminations, Isolators, Circulators And Many more.
- Built to satisfy most exacting requirements for splitting and combining RF & Microwave signals.
- Sampling incident and reflected microwave power conveniently and accurately with minimal disturbance to the transmission line
- Equally split an input signal with a resultant 90° phase shift between output signals or to combine two signals while maintaining
high
isolation between them
