Telecom networks are entering a period of large changes. Major discontinuities took place during the last decade such as the rapid development of high bandwidth networks enabled by ATM and Gigabit Ethernet, the convergence of voice and data enabled by VoIP and the introduction of high performance MPLS routers.
Convergence is now becoming predominant at the access level with fixed and mobile, and in the core network with ATM, IP and MPLS. However, the wireless transport part of the network has not progressed, as telecom incumbents so far had no incentive to change a status-quo that was providing them with high revenues.
Several factors will facilitate and speed up a major change in this approach:
- Explosion of the high speed cellular market (HSDPA,HSUPA,LTE) and of the broadband wireless market (Wi-Fi, WiMAX) and its increased geographical distribution
- Maturity of new techniques such as MPLS, IP VPN, Layer 2 or 3 connectivity, now industry standards
- Need for a new type of infrastructure, moving from multiple superimposed architectures, co-located but serving different types of services, to a single mutualised infrastructure, modular in functionality, capacity and coverage.
3Roam addresses these needs with a solution built for ease of deployment, scalability and affordability.
