Network

Consulting Services

External consulting services can benefit your network engineering department, especially when OPEX in under scrutiny and increasing permanent staff count is difficult. External network services can reduce time to market for a new technology, add capacity over a short duration when hiring permanent staff would be impractical, and can bring best practices from other operators into your engineering department.

With the 2013 purchase of AIRCOM International, a recognized leader in network services for almost 20 years, TEOCO gained a significant network services team and portfolio. In the past 5 years, the organization has successfully delivered over 750 network planning projects and more than 800 network optimization projects in all corners of the globe.

Our offerings provide a number of unique differentiators:

  • Independence from NEP’s means our planning efforts are not impacted by the equipment sales.
  • A broad planning tools portfolio, including the ability to leverage geo-location measurements, provides capabilities unmatched by consultants alone.
  • Global multi-vendor experience ensures we can share best practices from market leaders and our local knowledge ensures we are planning to market requirements.
  • Off-shore capabilities provide cost-efficient and timely deliveries.

We offer several types of network services spanning from: network planning, to spectrum refarming, and all the way to network optimization.

NETWORK PLANNING

A network design is the foundation for ensuring a high-performing network. A poor design can lead to poor performance and many hours spent attempting optimization, often without success. While designing and building greenfield networks is quite rare, network design is still an integral part of the network lifecycle as networks are continually expanded to match demand and new technologies become available.

We offer three primary categories of planning services:

  • New technology deployment
  • Network consolidation
  • Small cell planning

We also offer greenfield network planning when required.

New technology deployment: You need to keep pace with the latest technology releases to maintain competitiveness and meet customer demand. Adding a new technology, such as LTE, to an existing network brings significant technical and resource challenges.

Network consolidation: Mobile networks are going through a consolidation phase with many operators merging or signing network sharing agreements. Both of these scenarios mean you need to consolidate two networks into one to realize the financial and performance benefits.

Small cell planning: Many operators see small cells as the most practical method for coping with spiraling data growth. Due to their limited reach, however, placing them very close to the traffic is required. Planning within dense urban environments also brings challenges.

NETWORK OPTIMIZATION

As your networks evolve and customer behavior changes, it is critical for you to optimize your network configuration to maximize performance. Poor quality of experience is the primary reason most customers churn. As networks expand and traffic increases, performance typically degrades. Optimization is required to return network performance to initial levels, and possibly beyond.

We offer two primary categories of network services for optimization: coverage optimization and performance optimization. The services are provided via “solutions”, a powerful combination of tools, proven methodologies and optimization experts.

Key problems to address:

  • Coverage optimization – Because planning process are often weak, it is necessary to optimize coverage during the pre- and post-launch stages of a network roll-out to ensure it is providing as much good, interference-free coverage as possible. Many operators are also facing coverage problems, either failing to meet their license obligations or facing many customer complaints.
  • Performance optimization. As networks expand and traffic grows, performance typically degrades. Continuous optimization is required to keep the network running at its best. Performance typically has two dimensions activities that target specific issues on the worst performing areas of the network:
    • Providing focused recommendation and the wide area optimization that aims to deliver improvements across the whole network.
    • Affecting configuration parameters across the whole network or region.
  • Cluster optimization. Either due to new technologies or equipment being introduced, optimizing a new layer is required to maximize the performance. This is typically performed in small network clusters and affects the physical configuration.

SPECTRUM REFARMING

Spectrum is expensive. Any technologies you add to your network requires spectrum. Our analysis of prices paid for LTE spectrum in North America and Europe shows that existing GSM and UMTS spectrum could be re-allocated to LTE deployments for less than 0.5% of the cost of buying new spectrum at auction.

Lower frequencies propagate further and penetrate buildings better than higher frequencies. Lower frequency bands, however, are mostly fully allocated, meaning that many new technologies tend to use higher frequency bands to obtain the wide blocks of spectrum needed to achieve capacity and throughput requirements.

The easiest way to deploy a new technology is to co-site base stations with existing ones. Due to the reduced propagation of higher frequencies, this often means many coverage holes exist. Clearing a lower frequency band and using that for the new technology provides improved coverage and minimizes coverage holes.

Frequency planning, the primary activity required during a spectrum farming exercise, is not performed regularly by operators, meaning they typically don’t have the in-house expertise required. We have refarmed spectrum for over 25 customers in the past three years through network services, and have the expertise needed to release spectrum while maintaining your network performance.
