MAFTEL started its dedicated Telecom Practice in the late 2005. Over the years, the Practice has evolved into one of the leading players in Pakistan, providing Telecom Solutions.

Maftel is very aware that revenue generation for the Operator cannot begin until the site is on air and therefore speed and quality of site completion, after CME acceptance, is of prime importance. Maftel is well placed to maximize the Telecom Implementation (TI) window and has invested in all the appropriate tools, test equipment and resource training.

Key Maftel attributes for Customer confidence include:

Financial stability

• Professional, cost effective management of subcontractor organizations.
• Ability to work in a multi-cultural and geographically diverse environments
• Maftel is the one point of contact, reducing multiple interfaces, improving
• Communications whilst increasing quality and speed of delivery.
• Flexibility, capacity and capability to meet peaks in operational demand
• Vendor certified and in-depth familiarity with available technologies
• Vendor neutral with multi-vendor equipment competence
• Generic operating procedures
• Long term relationship partners

We have a qualified installation and commissioning team trained and certified on most of vendors' equipment.
The Telecom Implementation Module maintains details relating to the allocation and configuration of all equipment associated with a Site.

Users can create a library of standard equipment configuration templates and then use these templates to assign them to a Site. Once assigned to a Site, you can customize the equipment configuration to fit on-site requirements.
Our vast experience in providing end-to-end solutions to the Telecom industry has helped us to successfully map our competency, skills and expertise to the areas of Telecom Infrastructure.

Tools & Test Equipments

Drive Testing (DT) & Optimization of GSM & CDMA Networks
DT OVERVIEW

• Why we perform DT and What is DT.
It’s for testing of different RF parameters required by the customer in the coverage area and to determine where coverage is not fine. It is to verify planning requirement similarly to check network quality from end user prospective and to analyze network problem.

• Types of DT.
a. Indoor.
b. Outdoor.

The category of outdoor DT is sub divided into two types.

• Single site DT.
• Cluster Based DT (It is normally of 5 to 7 sites).

• Modes of DT.

a. Idle call test.
It is performed by keeping the test phone in idle mode.

b. Short call test.
In Short call test the test phone is in dedicated mode multiple calls are made and duration of each call should be from 30 to 45 seconds.

c. Long call test.
Long call test as the name suggests that test phone here is also in dedicated mode and a single call is made of long duration.

OVERVIEW OF DIFFERENT TOOLS.

• Planning Tool (Asset, Atoll)
• Dimensioning Tool (Back hall, Codes)
• Logging Tool/DT Tool (CNT, CAIT, Pilot panorama, Probe, Tems, Nemo)
• Post processing Tool (Actix, Genex assistant, Tems investigation)
• Spectrum analyzer (Tectonics, HP, Acterna)

DT KIT.

• DT Tool software.
• Laptop with charger and a battery of good health.
• Handsets with charger.
• Vehicle.
• Car charger.

DT PARAMETERS.

Following are the DT parameters for CDMA and GSM which we need to mention in our DT report.

a. Rxlevel (CDMA/GSM).
It is the receiving level of the signal and its unit is dBm. Best range of Rxlevel CDMA is from -70dBm to -95dBm and for GSM is from -40dBm to -60dBm.

b. Txlevel (CDMA).
It is the transmit level of the signal its unit is also dBm
Maximum value is from -21dBm to -23dBm.

Basically Rx and Tx are vice versa because of close loop power control.

c. RxQuality (GSM).
Best range of RxQuality is from -40dBm to -60dBm.It is to determine the call quality of the network.

d. Ec/Io (CDMA).
Ec stands for energy of the chip and Io stands for interface its unit is dB. Lower the value of Ec/Io bad will be the quality. Value of Ec/Io is considered to be fine from -2dB to -10dB

e. PN Graph (CDMA/GSM).
PN graph shows the coverage area of the particular sector of the site.

f. FER (CDMA/GSM).
FER stands for Frame Error Rate. It is evaluated in percentage. If the value of FER is above than 5 percent then we can say that there is some problem in the network.

g. HANDOFFS (CDMA/GSM).
In DT we monitor handoffs also.

h. SQI (GSM)
SQI stands for Speech Quality Index it is observed during our dedicated mode.

Events in DT.

Basic events in DT are,
  • Call drop.
  • GPS Disconnected.
  • Phone disconnected.
  • Handoffs.

Precautions kept in consideration.

  • Laptop should be fully charged.
  • All the required software should be working fine.
  • Enough space in hard drive.
  • Phone sets should be fully charged.
  • All the connectivity cables should be in working condition.
  • Enough credit for the DT.
  • Vehicle should have enough fuel to perform DT.
  • Drive route should be clear.
  • Sites in the selected cluster should be in working position.

Competitive Advantage of MAFTEL Telecom Services

• Single point of contact for site acquisition, engineering, construction, network services. Single point of accountability translates into cost effective solutions, streamlined schedule, greater reliability, flexibility and quality
• Efficiencies of Acquisition, Design and Build being under the same roof:

• Control of design and drawing issues in relation to program.
• Build ability aspects of each site are considered at the earliest stage.
• Close interface between acquisition, design, and construction from the outset, ensures that the site design meets the requirements of the local Planning Authorities and Operator to reduce the risk of delays and/or rejected proposals.
• Construction feasibility aspects of each site are investigated and considered at the earliest possible stage resulting in lower cost budgets for the Operator.
• Early interaction ensures detailed drawings are produced without the need for further information or amendments.
• Interaction from the outset will allow for economic solutions to be developed.
• Partnering of acquisition, engineering and construction in order to work as a team.
• Ease of arranging acquisition, design and construction visits at site identification stage to increase the success rate of the site.
• Fully documented design quality system.

• Health & Safety: Safety is regarded as one of our Key Performance Indicators (KPI’s). Our Safety Department has overall responsibility for safety within our organization. We have full-time professionally qualified Safety Managers who report directly to the Safety Director. Since its inception, MAFTEL has maintained an excellent safety record.

• Environmental Management System: We recognize that, while the end product of its activities should enhance the quality of the environment, the build out process itself, and the materials used, have a potential impact on the environment. We have developed an Environmental Management System with the aim of minimizing the impact of its activities on the environment. This Environmental Policy is reviewed annually.

• Quality Assurance: Our employees work to get it right the first time and have a positive commitment to quality and the ability to respond quickly and effectively to changing environments. Quality will be effectively managed through:

• Process and procedures
• Requirements and responsibilities defined early
• Continuous quality control
