July 2008). Formation of iBurstAssociation (iBA) a non-profit worldwide consortium established with its objective to promote and develop iBurst as the preferred solution for MBWA (April 2007). The iBurst technology has been commercialized in 13 countries, among which are USA, Canada, Lebanon, Norway, South Africa, Australia, Azerbaijan, Malaysia, Ghana and Tanzania. 6.10 Summary Insights This chapter presented an overview of the MBWA radio technology. The details of the air interface standard, network performance and architecture were provided. MBWA has to overcome a number of challenges. First, it was standardized way after HSPA+ and WiMAX. Another challenge is that it can be used only in licensed bands below 3.5 GHz as this is highly occupied by various other technologies. Thirdly, the requirement for handoffs at 250 km/h is very difficult to meet. Another challenge is that MBWA is not backward compatible to any of the existing cellular broadband solutions (EV-DO, HSPA, and WiMAX), making it difficult for any operator to justify the investment in an unproven technology. Another is the absence of a Forum for Wideband mode that can campaign for it like CDG, GSMA, WiMAX Form, and SO on. And, it is still not part of 3G IMT-2000 family of standards. Thus, it is very likely that MBWA Wideband mode will not be able to capture any share of the cellular and broadband market due to delay in its standardization and strong commitment from the industry for technologies like EPS, EV-DO, HSPA, and WiMAX. iBurst will continue a remain a niche technology and will not become a main stream alternative.
