DESIGN

A well planned radio network design needs to include coverage, capacity and desired quality of service. A design team today needs to have the ability to account for the shift in network assets from traditional macro only assets to a heterogeneous network design.
Scarlet Wireless has experience in all aspects of network design from propagation modeling and calibration (including CW drive testing and data collection). We are experienced in all major outdoor and indoor propagation and design tools. Scarlet Wireless can design a solution tailored to your needs by integrating our engineers into your existing team, or conducting designs utilizing our design assets.


We specialize in the design of:

RADIO NETWORKS

A well planned radio network design needs to include coverage, capacity and desired quality of service. Scarlet Wireless provides onshore and offshore RF design solutions that involve the following key activities:

  • Digital map data provisioning
  • Propagation Model Tuning for required planning tool
  • Site Evaluation
  • Preparation of Cell Design Data
  • Capacity Planning

MICROWAVE NETWORKS

A key bottleneck Operators currently face to realize 4G broadband data rates, is transport backhaul from the cell sites. Traditional T1 backhaul expansion is costly and time consuming and building fiber to the site, although a great solution, also impacts time to market.
A cost-effective and easily deployable transmission solution is a Microwave network. Scarlet Wireless has extensive experience in Microwave design and optimization.

NEW SITE BUILDS

DISTRIBUTED ANTENNA SOLUTIONS

IN-BUILDING NETWORKS

DAS

SMALL CELL SOLUTIONS

With the rapid growth in data traffic in the coming years which is not expected to ease, there is a real motivation for carriers to push an ever increasing number of end points in the network to stretch the bandwidth available to the end user. This includes a shift from macro deployments to a heterogeneous network of macro, DA and small cells; along with an aggressive in-building expansion.

Scarlet Wireless has extensive experience in indoor and outdoor DAS implementations, and is working with major vendors on their small cell developments. Scarlet Wireless utilizes iBWave certified engineers for indoor design.

Network Benchmarking – Drive Testing

NETWORK BENCHMARKING

DRIVE TESTING

Monitoring the quality of the network, and collecting data during site commissioning, or new technology implementation such as LTE and VoLTE, demands that a carrier have people on the ground gathering data of the network, where the customer will be. This is accomplished through drive testing and walk testing for indoor network deployments.

Providing our customers with a readily deployable and cost efficient means of gathering network data has been a core competency of Scarlet Wireless since our inception. We have the data collection assets available to quickly scale to your project, no matter the size. We have experience in both drive testing outdoor networks as well as collecting indoor network data through walk testing. We have the tools and the experience to meet your needs.

OPTIMIZATION

PRE-LAUNCH

Turning on a new site has an immediate impact on customer perception of your network’s performance. To ensure that perception is positive, we can benchmark and optimize the performance of sites prior to commercial launch.

POST-LAUNCH

Expansion in a network due to coverage, traffic growth or new feature introduction will impact the performance of the entire market. We use drive test data and network statistics to optimize cluster and market performance to improve overall market KPIs.

RF DRIVE TESTING
DATA COLLECTION &
DATA POST-PROCESSING

Air-interface data collection using tools like TEMS is essential to collect RF performance data for both outdoor and indoor environments. Data can be collected and post processed in both an onshore and offshore model to meet client’s needs and budgets. Scarlet Wireless has experience in the post processing of the drive testing data to aid in the optimization of the network. We utilize experienced RF engineers to analyze this data and recommend physical network changes as well as parameter changes to meet required KPIs and get the most out of your network investment.
