2G, 3G and LTE Wireless Access Engineering

The wireless access along with the data transmission and core networks make up the three key components of modern mobile communications infrastructure. The wireless access network is also known as the BSS (Base Station Subsystem) or the RAN (Radio Access Network). Wireless access networks have constantly evolved converging into an architecture known as SRAN (Single Radio Access Network) today.

The ultimate goal of the telecommunication industry is providing seamless voice and data connectivity to the end-user anywhere and anytime. The realization of this long-term ambition heavily relies on further improvements of the mobility concept. Mobility is also synonimous to the use of modulated radio signals as transmission vehicle of the wireless access. The challenge in such an environment arises from the fact that an unlimited number of connections should be handled over a limited radio signals ressources due to the nature of electromagnetic spectrum.

Engineering the wireless access is considered one of the finest tasks in mobile telecommunications. Unlike planning a fixed access network, the quality and availability of wireless access networks depend on a large number of parameters that can only be determined with a fair amount of approximation. A spectral density distribution map of the radio signals, also known as coverage map, is generated with the help of mathematical models. The standard deviation of the predicted coverage to the live network performance will have a direct impact on KPIs (Key Performance Indicators) ratios as well as on CAPEX and OPEX.

Wise Noble Limited will assist you in the completion of the following wireless access engineering tasks:

• RAN rollout - also known as the initial infrastructure setup of the wireless access network. The main goal here would be to provide paramount radio signals coverage and service bandwidth while pursuing a satisfactory ROI (Return on Investment). Along with the usual cell site planning and engineering tasks we follow a strategical deployment approach revolving around a long term vision of market and technology evolution. In addition, our solution will account for customer base segmentation and distribution, service utilization shaping, short and long term prediction of behavioral trends, risk assessment and impact of spectrum shortages, just to name a few.
• RAN optimization - or the follow up phase after the RAN rollout is completed. The rapid growth in the number of RAN elements during rollout naturally leads to an increased complexity in their interoperability relationships. Relying on a pool of live network KPIs, benchmarking, drive tests, call tracing and customer feedback, an elaborated optimization plan is established addressing performance laggards. Key component in the RAN optimization plan is the implementation of solution milestones each addressing a specific engineering activity. This approach is necessary in order to minimize the impact on live network services and exercise strict control over costs.
• RAN upgrade - driven by shorter depreciation cycles, increased computing capabilities and reduced power consumption of the hardware, mobile network operators around the world have been rushing to modernize their infrastructure by swapping or upgrading RAN elements on a massive scale. As multi-vendor support has always been deeply routed in wireless network standards, global market players will not hesitate to frequently switch vendors to get competitive advantages or simply to lower their OPEX. Carefully defined cross-platform mapping of a large number of functional RAN parameters will not only smoothen the vendor transition but will also guarantee the wireless access KPIs.
• RAN audit - recently gaining on popularity among mobile network operators worldwide as more and more of RAN rollout, -optimization and -upgrade activities are entrusted to third party contractors. The short project turnover cycles make it almost impossible to achieve high implementation quality standards. An independent professional review and overall assessment of RAN KPIs and services will contribute to the instant benefit for the involved parties and ensure the wireless access network viability in the long run.
