| Service offerings: |
|
| :: CW Test and Model Tuning |
 Model Tuning, one of the important modules of Radio Network Planning & Design, simulates the propagation of the RF signal on the air in order to obtain accurate radio coverage and interference predictions in the service area.
In the Model Tuning activity, RF measurements are performed in the different areas of the planned network. Collected data is used to tune the propagation model parameters in planning and stimulation tools.
|
| |
| :: Nominal Cell Planning |
| Using the information specifying the coverage and capacity requirements for voice and data services of the radio network being planned creates the Nominal Cell Plan. Planning tools (viz. Planet EV, ASSET3G etc) help perform Nominal Cell Planning activities using the propagation loss model as generated by model tuning and other relevant marketing inputs. |
| |
| :: Radio Network Design & Planning |
| Detailed design and planning is carried out to deliver parameter planning, frequency planning, traffic planning, neighbor planning and creation of data build. A unique on site – off site model offers economies of scale and faster ramp up for our valued customers through our virtual planning and optimization centre.
Swap Planning is the mapping of the existing network RF parameter with promoting vendor parameter to achieve an equal or better KPI. |
| |
| :: Transmission Network Design & Planning |
| Planning of backbone and access network – PDH, SDH, DWDM, ATM etc.. Link budgeting, interference analysis, creation of connectivity matrix, detailed microwave planning. |
| |
| :: RF / LOS Survey |
| An RF survey is conducted to finalize the feasible sites based on Nominal Cell Plan data. This activity commences as the completion phase of pre-planning nears. An LOS (Line of Sight) survey is conducted on the final survey site to verify the M/W connectivity to the planned site. |
| |
| :: Network Optimisation |
Verification Drive Test -
With a site on air, it is necessary to check the performance of the new site. This is done through verification drive tests. The sites are checked for validating integration parameters and ascertaining call performance: call termination, call origination, handover, power control RX Quality and RX Level etc. |
| |
Parametric Optimisation -
Once a radio network is operational, its performance is monitored. The performance is compared against chosen key performance indicators (KPIs). After fine-tuning radio parameters, the results are applied to the network to achieve the desired performance. The main focus of radio network optimization is on areas such as power control, quality, handovers, subscriber traffic, and resource availability (and access) measurements. |
| |
Periodic Monitoring & Optimisation of the Live Network throughout the Network life-cycle -
Regular monitoring of the network health (new rollout and expansion) by doing drive tests and KPI maintenance. |
| |
| :: Network Audit, Benchmarking & IBS Planning and Design |
Site Audit -
Site Audit is a process that identifies discrepancies between the design and implemented network. |
| |
Benchmarking Services -
Benchmarking Services is a comprehensive comparative analysis that provides details on in-market analysis and network review. The service evaluates performance against competition and measures network performance using a Drive Test to examine coverage and call quality. Tests are conducted for call availability, call quality, call set up success rate and handover success rate. |
| |
IBS -
An indoor system can be built for different reasons. If the coverage is poor from cells outside the building, leading to bad quality, one solution can be to build an indoor system. The aim with indoor cell planning is, as for traditional cell planning, to plan for good coverage and capacity and at the same time interfere as little as possible. |
| |
| :: Virtual Planning and Optimisation Centre |
| A unique concept of a combination of onsite and offsite model to carry out Network planning and optimization for wireless networks. It provides benefits like low fixed costs irrespective of location of project, fast delivery cycle and quick deployment of project, cost effective and flexible service packages to meet unique customer needs. |
