With the rapid adoption of video-capable smartphones and larger-screen, high-resolution video devices, wireless networks have become wireless multimedia networks. As wireless networks become multiservice broadband vehicles, the dramatic increase in signaling and high-bandwidth traffic is putting mobile service providers at risk of major network breakdowns and performance loss. Exploding traffic growth: Mobile internet Increasing network complexity Operators under margin pressure All networks evolving to IP
The valid approaches to improving network bandwidth and quality can be bucketized into 3 groups: Avail more raw bandwidth when and where it makes sense (LTE, more carriers/more spectrum on 2G/3G) Leverage topologies that can produce the same result quicker and more economically (small cells, smart antennas, DAS, beam forming,) Focus on network performance optimization, which can often delay investment in either of the above, and lower network costs regardless Naturally, all networks will arrive at IP to improve scale, reduce cost, and gain efficiency. Our strategy is to take the leadership of the Wireless IP generation, addressing the three critical levers highlighted above: Lead in the expansion to LTE (which is the recognized next generation air interface technology), and significantly grow our market shares in CDMA, W-CDMA and GSM, all of which are critical in optimizing capacity Lead in the deployment of small cells in home, enterprise and metropolitan environments. This represents a natural extension of our fixed Broadband leadership, as Small Cells share with DSL and FTTH the same locations, architecture and physical constraints. Lead in end-to-end Wireless IP traffic routing and management using key innovations in Wireless traffic management and our leadership in building the most performing IP networks. Taken to the ultimate, our prowess in end-to-end IP services management, instrumentation, and self-optimizing networks will lead to emergence of Self-Everything — a world in substantial network automation reduces the cost per bit served dramatically. Our Wireless IP strategy has already be shared with major existing customers and key new potential ones. Their feedback is unanimous: we are addressing the right issues and few in the market have reached this level of thinking.
