Cornered! is a blog devoted, most of the time anyway, to telecommunications: local and global issues, technology, people and trends from the perspective of someone who's been reporting, analysing and commenting on the industry since the dark ages (BC - before competition). Sometimes serious, sometimes flippant, sometimes frivolous. Controversial, analytical, informative, amusing, but never boring; a vehicle for examinations of important issues and observations on my encounters and experiences in an industry where polarised views and hyperbole are the norm.

Coonan has a strong champion for WiMAX in Motorola. I recently interviewed Ray Owen, head of technology for south & east Asia for Motorola Networks & Enterprises, who told me: "LTE has not been fully standardised but both WiMAX and LTE are IP based so we can at least say that WiMAX is heading in the right direction." Owen claimed that the WiMAX technology which is time division duplex (TDD) and therefore uses the same frequencies for transmit and receive has a number of cost advantages over WCDMA which is FDD and uses separate frequencies for transmit and receive. "A chipset comprises a digital part and an RF part. The cost of the digital part has gone down considerably over the last few years, but the RF part is the biggest cost and when you go to TDD technologies you have far fewer RF components so we know that the chipset for WiMax will be much cheaper than 3G [setting aside any volume advantages]." He said that the single frequency mode of WiMAX conferred an additional operating cost advantage. "Data is inherently asymmetric, so having an up and a downlink does not help you a lot [HSPA uses 5MHz for each of the up and downlink]. With WiMAX you can allocate the whole bandwidth to the up or downlink if necessary." |
