Network optimisation the key to LTE success

Whether mobile operator performances have been challenged by difficult economic conditions or competition in saturated markets, their 2010 capital expenditure mix will be based on either network modernisation or new technology rollout. From what we heard at Congress last week, our view is that it is likely to be an 80-20 mix with operators opting for a more cautious approach. While LTE deployment still very much depends on tomorrow's higher spectrum allocation (and its regulations), network infrastructure vendors concerned themselves with discussing how to support mobile operators in optimising their network capacity. Ericsson noted that - even though smartphone users own a small share of an operator's installed base - they use most of the network capacity; around 300-500 MB per month compared to voice users who only dent 10-50 MB per month.
It essentially means that networks have to be modernised to address issues linked to increasing demand in data traffic, demand in quality, cost efficiency and energy efficiency. Modernising and optimising mobile backhaul involves equipment with fewer components and a higher life-cycle from which operators can generate cost savings of up to 30 percent (from legacy cost). Ericsson demonstrated its new solutions such as its microwave-optical hybrid system, while Texas Instruments detailed their focus on power allocation depending on consumption and time of the day to improve power efficiency. Hence, even though Congress was full of latency readers showing the speeds LTE can gloriously achieve on a good day, we know that mobile backhaul was what everyone was secretly discussing in the meeting vaults.

The Mobile Economy Asia Pacific 2025
Mobile connectivity supports efforts to develop modern, inclusive and sustainable digital nations in Asia Pacific, facilitating the increasing integration of transformative technologies such as AI into daily activities for individuals and businesses. In 2024, the mobile sector accounted for 5.6% of GDP in Asia Pacific, contributing $950 billion in value. This is expected to rise to $1.4 trillion by 2030, equivalent to 6.6% of GDP, as the impacts of 5G technology become more widespread across local economies. To fully unlock this potential, fostering digital trust and ensuring the sustainability of the industry have become key priorities for stakeholders across the region's digital ecosystem. This means driving 5G monetisation, addressing the scam economy and mitigating cybersecurity threats, alongside bridging investment gaps, balancing innovation with regulations and implementing effective spectrum policies.
The mobile churn challenge: where loyalty is lowest and four recommendations for operators
The latest consumer survey by GSMA Intelligence reveals that around one in seven mobile users changed their service provider over the previous 12 months. The main reasons for churn have stayed largely unchanged over the last five years, at the aggregate level, with value for money by far the top reason. However, variations exist between consumer segments in terms of the degree of churn and the drivers.
MWC Shanghai 2025: a window into the future?
MWC Shanghai is in the books for another year, having attracted 45,000 visitors (from 12,500 companies), along with 400 exhibitors and partner groups. The numbers were up from the 2024 event by 13% and 92% respectively. This analysis highlights the key takeaways and implications from meetings, summits and announcements at the event – and in particular, whether the progress seen in China can be mapped to other regions.
