Five tracks tracing the career of chet baker through his session and concert recordings from 1955 to the final concert on April 28 1988 - recreated by Caroline Cooper on piano, Peter Miles on drums, Clive Brown on double bass and Geoff Varrall on trumpet.

In this month's podcast, Geoff Varrall discusses the likelihood and potential scale of a value shift from terrestrial to space based communication networks.

In this month's podcast, Geoff Varrall talks about the technology economics of Ku, K and Ka band Geostationary, medium earth and low earth orbit satellites (K-SATS) and the related implications for 5G business modelling.

In this month's podcast, Geoff Varrall discusses servers in space, also known as dot.space or above the cloud computing, exploring the profound impact that technology and commercial innovation is having on the satellite sector and how this influences the 5G business model and 5G financial viability.

In this month’s technology topic podcast, Geoff Varrall talks about implementing 5G in existing LTE spectrum or rather, as the title implies, into existing bands at 900 MHz and below.

In this month's Technology Topic podcast, Geoff Varrall develops a narrative previously covered in the August 2016 Technology Topic, Satellite Spectrum and Standards, which highlighted the developing interdependency of the 5G and satellite industry in terms of technology innovation, technology standardisation and spectrum, but this time with more attention on the need to achieve cross amortisation across RF hardware platforms including point to point backhaul.

In this second Technology Topic podcast Geoff Varrall discusses the implications of the FCC release of additional unlicensed spectrum above 60 GHz , how this could potentially enable a new generation of ultra-wide band technology and how this might deliver complementary local area connectivity to Ka-band and E band 5G

In the first of the Technology Topic podcasts, Geoff Varrall explores the developing involvement of the GAFA (Google, Apple, Facebook and Amazon) quartet in terms of network ownership and added value. He also discusses the changing dynamics of the 5G and satellite supply chain, how technology is reducing CAPEX and OPEX in the satellite industry, increasing CAPEX and OPEX in the mobile broadband industry, and the related implications for future competitive positioning.
