The Growth of Mobile Broadband Services

As consumer and business data services are increasingly accessed via advanced portable wireless devices, operators need to adapt and improve their networks to offer more and better services. Broadband mobile services like high definition video and other bandwidth-hungry applications will soon become commonplace around the world, and in the next five years they are expected to increase cellular network traffic by a factor of 20.


New mobile networks based on C-RAN – Cloud Radio Access Network – architectures are the next logical step for mobile operators who wish to deploy these advanced services, which are known as LTE-A, short for Long Term Evolution - Advanced and, in the future, also 5G.


C-RAN is an architecture that enables greater mobile coverage and provision of these new services. It requires the deployment of vast numbers of radio antennae that are connected via fiber optics to Central Offices (CO) where pools of BBUs (BaseBand Unit Controllers) are located. The COs contains all of the operational intelligence, allowing the antennae to be extremely lightweight and highly cost-effective. 


The fiber optics that run between the C-RAN antennae and the CO – also known as the Mobile Fronthaul or MFH – need to carry multi-gigabit CPRI (Common Public Radio Interface) protocol signals, and eventually, also Ethernet signals. Optical Transport Networks (OTN) technology is a high-quality and well-accepted method for transporting these signals.


IP Light’s Apodis and Orion OTN processors effectively address these requirements. Apodis processors offer a unique solution for of CPRI, OBSAI and Ethernet signals drawing on an ITU-T G.709 based implementation, therefore allowing the transport of up to 4 CPRI-3 signals over a single, standard, OTU2 bearer (10.7G). Orion IP cores, developed in conjunction with Xilinx, the world’s largest maker of FPGAs, support the newly defined ITU-T SG15 Q.11 Supplement 56 Section 8, enabling the transport of up to 6 CPRI-3 signals over the newly defined OTU2r (11.8G) signals. Orion processors are optimized for the delivery of CPRI signals, enabling the reuse of existing optical infrastructures along with new fiber optic lines while meeting stringent CPRI transport requirements. Equipment providers that integrate IP Light’s Apodis and/or Orion OTN processors into their offerings, enable carriers to take a forward leap to C-RAN based mobile services, not only supporting the cost-effective deployment of CPRI over OTN, but also supporting a wide range of additional services.


Carriers can use network equipment with integrated IP Light Apodis or Orion OTN processors in order to maximize the utilization of their fiber networks, deploying broadband wireless services quickly and cost effectively
