A Proposed Process for Spectrum Re-farming
To request a copy, click here.
The ability
to deploy third generation technology (UMTS, HSPA) on the 900MHz bandwidth has
been, and continues to be, of great benefit to the mobile systems world,
allowing Operators to meet exponentially rising demand for mobile broadband
services. By clearing spectrum from an existing GSM 900 band to allow for
UMTS900 deployment, Mobile Operators
have an opportunity to offer more cost-effective services with wider coverage and superior building penetration. This paper
presents a proposed process for spectrum re-farming which provides solutions
for meeting challenges, as well as the recommended tools and benchmarks to
guide and manage the process.
Planning Scrambling Codes the Right Way

Scrambling Codes (SCs) are the internal method used to identify and distinguish sectors from one another in 3GPP compliant WCDMA networks.
Based on a deep understanding of Scrambling Code usage and 3GPP standard definitions in WCDMA networks, Schema suggests a novel approach for SC planning, which also takes into account SC usage during the handover process in order to prevent common failures. Schema`s advanced solution for SC planning takes into account the handset “experience”, in any location, and ensures that Scrambling Codes are allocated in such a way that minimizes contradictions for required Neighbor List plans.
Automating UMTS Optimization.
Schema`s approach to UMTS optimization eliminates tedious trial and error processes by automating the fine-tuning of vital network parameters. Integrating advanced automated cell parameter planning techniques increases capacity and coverage, in addition to ensuring a smooth migration to new technologies. This white paper, originally published for the UMTS 2001 Expo, explains the advantage of Schema`s automated cell planning technology over the traditional solutions available today.
Computers Imitate Natural Selection to Solve Intractable Problems
Schema`s evolutionary optimization technology is based on evolutionary algorithms that imitate nature`s trial-and-error problem solving methods, to allow for the continuous and rapid improvement of existing solutions, until the optimal solution is found. Dr. Yuval Davidor, Schema`s President and Founder, is the scientific creator of this innovative approach to optimization.
Correcting the Approach to Optimal Cell Planning for WCDMA Networks
This paper presents the unique elements involved in WCDMA network planning. As many of the cellular engineers involved in the network planning process come from a background of GSM planning and optimization, there is a need to adopt new work methods to support this new and advanced technology.
Wireless Network Optimization Before, During and After Technology Transition
Most operators of TDMA (IS-136) wireless systems in the Americas are currently transitioning to other air interface technologies or are planning to do so in the very near future. There are a number of compelling factors driving this very costly undertaking. This paper discusses some of the most pressing radio network issues facing carriers involved in technology transitions, and how various optimization products can help.
Genetic Algorithms and Optimization Solutions for the Telecom World
The purpose of this brief white paper is to provide a more in-depth view of the technology and workings behind Schema’s optimization products. In particular, this paper explains what GAs are, why they work, and how the GA powered optimization engine inside Schema products is special when compared to other products available in the marketplace.
