Integration of next generation wireless technologies i.e., WiMAX (Worldwide Interoperability for Microwave Access)
and or LTE (Long Term Evolution) with EPON is a brilliant concept that gives users the best of two worlds, wireless
and wired. WiMAX gives users the convenience of mobility while integration with EPON gives theoretically unlimited
bandwidth of fiber optic cable in backhaul. This paper investigates WiMAX and EPON technologies. At the end
different scenarios of integration of EPON with WiMAX are discussed and optimal QOS mapping scheme is proposed
for the integration of EPON and WiMAX.
This paper presents the key features of the emerging Next Generation Passive Optical Network (NG-PON) and IEEE
802.16m based Mobile Worldwide Interoperability for Microwave Access (WiMAX) networks to build a unified cost
effective next generation hybrid Fiber-Wireless network. NG converged-access solutions can meet the demand for cost,
mobility, bandwidth, reliability, security, and flexibility. NG-PON and 4th Generation (4G) Mobile WiMAX unified
architecture enables differentiated bandwidth allocation to end users and can provide more network range and capacity at
reduced operational cost. The concept of hybrid optical network unit and advanced base station (ONU-ABS) simplifies
the network architecture and can save some installation and operational costs.
In this research paper we propose a novel Passive Optical Network (PON) based Mobile Worldwide Interoperability for
Microwave Access (WiMAX) access network architecture to provide high capacity and performance multimedia
services to mobile WiMAX users. Passive Optical Networks (PON) networks do not require powered equipment; hence
they cost lower and need less network management. WiMAX technology emerges as a viable candidate for the last mile
solution. In the conventional WiMAX access networks, the base stations and Multiple Input Multiple Output (MIMO)
antennas are connected by point to point lines. Ideally in theory, the Maximum WiMAX bandwidth is assumed to be 70
Mbit/s over 31 miles. In reality, WiMAX can only provide one or the other as when operating over maximum range, bit
error rate increases and therefore it is required to use lower bit rate. Lowering the range allows a device to operate at
higher bit rates. Our focus in this research paper is to increase both range and bit rate by utilizing distributed cluster of
MIMO antennas connected to WiMAX base stations with PON based topologies. A novel quality of service (QoS)
algorithm is also proposed to provide admission control and scheduling to serve classified traffic. The proposed
architecture presents flexible and scalable system design with different performance requirements and complexity.
Passive Optical Network (PON) and Mobile Worldwide Interoperability for Microwave Access (WiMAX) are two
emerging broadband technologies for the next-generation (NG) access networks. Integration of PON and Mobile
WiMAX might be an efficient solution to broadband network access that can take advantage of the bandwidth benefit of
fiber communications, and the mobile and non-line-of-sight features of wireless communications. By leveraging the
advantages of both of these access technologies combined on an integrated architecture platform, NG converged-access
solutions can meet the demand for mobility, bandwidth, reliability, security, and flexibility. By combining the practically
unlimited capacity of optical fiber networks with the ubiquity and mobility of wireless networks, NG Fiber-Wireless
(FiWi) networks will enable the support of a wide range of emerging and unforeseen fixed-mobile applications and
services independent of the access infrastructure. PON and 4G Mobile WiMAX integrated architecture enables
differentiated bandwidth allocation to end users that can provide more network capacity at reduced operational cost as
compared to other existing technologies.
Mobile networks and services have gone further than voice-only communication services and are rapidly developing
towards data-centric services. Emerging mobile data services are expected to see the same explosive growth in demand
that Internet and wireless voice services have seen in recent years. To support such a rapid increase in traffic, active
users, and advanced multimedia services implied by this growth rate along with the diverse quality of service (QoS) and
rate requirements set by these services, mobile operator need to rapidly transition to a simple and cost-effective, flat, all
IP-network. This has accelerated the development and deployment of new wireless broadband access technologies
including fourth-generation (4G) mobile WiMAX and cellular Long-Term Evolution (LTE). Mobile WiMAX and LTE
are two different (but not necessarily competing) technologies that will eventually be used to achieve data speeds of up
to 100 Mbps. Speeds that are fast enough to potentially replace wired broadband connections with wireless. This paper
introduces both of these next generation technologies and then compares them in the end.
