News In Brief: Amazon; NTT DoCoMo; Huawei

Figures from Amazon reveal the meteoric rise of the e-book, with online versions now outselling combined hard- and paperback editions less than four years after the firm launched its Kindle reader. The firm has sold 105 e-books for every 100 regular books sold since April 1.
NTT DoCoMo is preparing to demonstrate a prototype multiband power amplifier it claims frees up space used by current single-band units by offering access to six frequency bands between 1.5GHz and 2.5GHz. Components firm Renesas helped develop the processor, which measures 8.05mm x 6.2 mm.

Huawei has drafted in Andrew Cahn as chairman of its new UK advisory board. The former chief executive of UK Trade and Investment is tasked with developing the long-term strategy and targets for the board.
