One of the themes that emerged from the LTE World Summit was that no one was looking at WiMAX as a competitor for LTE. LTE is being thought as 'Mobile Broadband' whereas WiMAX is being thought more of as 'Low-mobility/Fixed Broadband'. They would serve different needs and their market will hardly overlap. I have blogged about iBurst in the past and I think it may give some competition to WiMAX.
David Brunnen from Personal Broadband UK (cant find their website) gave an interesting perspective on iBurst and even though many people have not heard of it, it can still compete in the market. They have a big presence in Australia and last year won the spectrum for the whole of Ireland + Northern Ireland between 1785 - 1805MHz. Even though they have won the 20MHz band, they think that they can do with 5MHz or maximum of 10 MHz. They have also partnered with iBand and would probably allow roaming between them.
The main thing about iBurst is that it has very good spectral effeciency and an average throughput of around 600kbps. Data Rate of 1.061Mbps downlink/ 346Kbps uplink with System capacity 24.4Mbps downlink/ 7.9 Mbps uplink is supported. At the same time it offers high mobility with handovers at speed of over 100kmph. The cell radius is 1.5-3km in urban and 5-7km in rural area. Because of adaptive antennas, the same frequency can be reused and the interference can be reduced thereby increasing the cell capacity.
The biggest problem with iBurst is that there are very few players. Kyocera is the only base station supplier. On the devices side, Kyocera is the lead player but there are other new players like Dovado which has won some big contract with first US iBurst operator and Moovera (bought by Icomera) which also has some similar devices.
Last year Kyocera announed that iBurst has more than 140,000 subscribers. This year iBurst South Africa has been shortlisted for an award of "Best Operator in Developing Country". In last 6 months they have increased the subscriber numbers by 30%.
With the big players heavily invested in HSPA+/LTE and many others having a foot in WiMAX, it would be interesting to see how a possible iBurst success might be viewed. I would like to hear from people who have experienced this technology on what their feeling is about iBurst.
