Lte Forum Sweden April 2010 Ventura Lte Discussion


Published on

Ventura addresses the question of whether it makes sense for legacy 900GSM operators in the UK to bid on 800MHz spectrum in view of a proposed sub-1GHz cap on spectrum. Using our suite of wireless technology models, we calculate under different network clutter types for Greater London and Cambridgeshire the conditions under which it would make sense to deploy LTE in 2.6GHz, 800MHz, or persist with HSPA. Our conclusions validate anecdotal evidence that for legacy 900GSM MNO's, there is little to be gained from bidding on 800MHz unless to achieve deep rural coverage.

Ventura has a comprehensive suite of network technology models that are able to calculate network CAPEX and OPEX for GSM, UMTS/HSPA, LTE and WiMAX for any spectrum allocation at any spectrum band. The suite has been designed with CTO technology selection decisions in mind and allows for multi-technology comparisons - quick and simple it isolates the major cost drivers from the perspective of the technology executive. The model outputs cumulative CAPEX, network cost/GB and customer profitability. Used in conjunction with our revenue and market share model, the combined suite can be used to undertake detailed business planning and valuation.

  2. 2. Should original GSM900 MNO’s in UK bid for 800MHz? • Loss of 900Mhz (2x10) and significant migration and disruption costs. • Both Vodafone & O2 have invested heavily in UMTS/HSPA. • Both legacy 900GSM operators are investing in HSPA Plus. • What would we have to assume about the growth of data for it to make sense for Vodafone UK & O2 to deploy LTE nationally?

  13. 13. LTE vs HSPA Cambridge: comparable service speeds LTE 800MHz (2x10) converges towards HSPA Plus at higher data speeds. No real 16GB/month advantage to deploy in 800MHz. 26GB/month 9GB/month At lower data levels - LTE 800MHz (2x10) offers coverage benefit over HSPA up until ~ 9GB/month Spectrum costs excluded from analysis.

  18. 18. Conclusion – we have validated conventional wisdom • Geography where 800MHz is beneficial may be limited to deep rural coverage, transport corridors. • LTE works best in 2x20 as is generally understood. • 800MHz is potentially less valuable to legacy 900GSM operators (also migration costs). • More likely deploy LTE in 2.6GHz and in the longer run migrate voice to 2.1GHz and deploy LTE in 900MHz. • Despite not having access to 800MHz a 900GSM MNO can still launch a compelling broadband proposition in 2.6Ghz. • H3 possibly well positioned to acquire lower band spectrum and deploy a nationwide broadband network.
