R F Nominal Planning
TCG RF Engineering Resources are well trained to use state-of-the-art industry standard tools for design, planning and testing the networks to ensure that the network design meets the network performance objectives of the customer.
RF Site Survey & Site Selection
The ultimate goal of a RF site survey by TCG is to acquire ample information to determine the number and placement of access points that allows optimal coverage throughout the facility. RF site survey is carried out in the following steps:
- Collect list of Nominals to be surveyed, from the customer. In case of new town surveys where Nominals are not provided, TCG will survey the town and provide a nominal for suitable site location
- Use the survey report template forwarded by the customer
- Identify physical location of the proposed nominal and locate 3 candidates (maximum) for each nominal, as per search ring size suggested by the customer
- Survey the site for RF suitability
- Record Latitude and Longitude, building height etc. of the proposed candidates
- Estimate and provide required GSM Antenna heights and orientation, proposed tower / pole location (s) will also be marked on a rough sketch of the building (rooftop) or ground site (for each candidate)
- Take site photographs (360 degrees panoramic view and building / site elevation) for each candidate as given in the survey template by you
- Record physical addresses of the candidates and site owner / manager contact details (where available)
- Complete the Site Survey Candidate evaluation report
In Building Solutions
We offer In-building solutions with GSM/GPRS and Wireless Lan (Wi-Fi) technologies. One of the fastest changes in mobile network rollouts is occurring inside the buildings. Picocells are the ideal solution for providing coverage, capacity to indoor traffic hot spots and other priority installations, such as;- Airports , Railway stations, Hotels, Shopping centers, Hospitals and Large corporate clients.
It has been estimated that 70-90% of all mobile calls are made inside the buildings. It has also been noticed that it is becoming too expensive to increase the indoor location probability by outdoor sites (>90%). So the easiest way to provide good in-building coverage is to use picocells inside the building. That provides good coverage and capacity inside the building and at the same time releases capacity to outdoor cells. These solutions are mostly based on Distributed Antenna Systems (DAS), Fiber Optic Distribution Antenna Systems (FODS) or picoBTSs
