Network Engineering & Integration

The wireless industry is immersed in next generation technology as it tries to transition from 2G to 3G and 4G networks. Spectrum and technology developments such as UMTS HSPA, CDMA EVDO and WiMax will end the Radio Access Network (RAN) bottleneck as we know it and introduce daunting challenges in network design and migration to stay abreast of broadband service offerings.

CellWorx remains at the forefront of wireless network engineering and integration. Our RF Engineering teams apply the systems expertise mastered in 2G and 3G networks to the next generation Radio Access Network, achieving superior results.

Our transport engineering teams lead the way in designing new architectures to address legacy and next generation networks. Moreover, we excel at integrating what we design, assuring our clients that cost targets are met despite the increasing traffic demands in the transport network.

Core networks are also in upheaval as packet technologies extend their reach. Architectures, roadmaps and integration plans must be implemented to support converged services enabled by IP Multi-media Subsystem (IMS) and other packet-driven technologies.

Our Network Engineering & Integration team stands ready to support your needs.

• Route Management: Sub-Network Protocols Analysis, IP Router Configuration

• Performance Optimization: QoS, Routing Optimization, IP Performance and Resource Management

• Security and Virtual Private Networks: Needs Analysis, Customization and Solution Integration

• IMS and Softswitch: Gateway and Server Placement and Dimensioning, Signaling Optimization

Transport Engineering

CellWorx peer into the future with rigorous engineering models vital to effective designs. CellWorx engineering leads the industry in the planning, design and optimization of backhaul and backbone networks. We are strong in efforts to contain what is widely regarded as the fastest growing operating expense in carrier budgets.

We work closely with our clients addressing the hard issues of today:

• Integration of 2G, 3G & 4G into a common transport network
• Implementation of transport designs to capture cost savings
• Migration and conversion to all IP networks
• Development of transport architectures

• Transport/Telco Hardening and cost effective route diversity

• Assessment of alternative transport technologies including T1/DS3, fiber rings, metro Ethernet, microwave, LMDS and WiMax.

RF Engineering

CellWorx RF Engineering Group has been playing a key role in the evolution of wireless networks. We ensure the RF component to carrier networks is designed and optimized to its fullest potential. Our baseline engineering services include:

• Network Optimization: Switch Parameters Definition and Tuning, Drive Test and Analysis, Datafill, Frequency and Capacity Planning, Switch Performance Analysis

Mobile Data Platforms & Applications

Mobile data is finally achieving long awaited customer acceptance as carrier data revenues approaches the billion dollar revenue mark. Future success will be determined by effective development of the mobile data platforms-the complex web of data platforms and applications, content developers, providers and aggregators and equipment and device providers.

The Present approach, a vertical service architecture per service, can no longer keep up with rich new service offerings and customer demand for a compelling user experience.

Carriers are now redesigning their mobile data network infrastructure in preparation for the onslaught of new services to leverage the broadband radio access platforms inherent in 3G and 4G networks.

CellWorx plays a key role in the engineering across the entire mobile data Platforms. Our domain expertise in data platforms, mobile portals, and content management enables service providers to architect their data strategies for maximum value and efficiency.

Our deep understanding of interoperability and connectivity across devices, bearer technology, core enablers, and back-end billing and database systems pays rich dividends as we test, validate and integrate data applications.

Data Applications

CellWorx collaborates with service providers to improve their Network performance and efficiency of existing mobile data platforms. We establish benchmarks for key metrics such as throughput, latency, reliability, and cost. We have extensive experience in design and integration of new or upgraded network elements to support the requirements of emerging technologies.

Our experts have worked extensively in the application design and integration of Location Enhanced Services, Streaming Media, Games, MMS, SMS, Messaging, Ringtones and IM.

Software Solutions

While the transformation continues from hardware-based and proprietary to software-based and open - many challenges remain. Complex architectures, vendor dependencies, and legacy applications clash with new requirements and the need to integrate fast. Solutions are varied and come in many forms but most are software based - from middleware to API development to new feature development, testing and integration. Regardless, success in today’s carrier environment is dependent on custom software solutions that work.

CellWorx has a highly skilled software solutions team specializing in network engineering. We partner with our clients in a wide variety of software development initiatives:

• Feature development for mission critical applications

• Engineering tool development

• Automated test tool development

• Software testing and integration

• On-going software maintenance and support of production systems/applications
