“…The availability of a hybrid system comprising of an FSO main link and 40 GHz back up link was measured to be 99.92% compared to 96.8% availability of FSO alone [6]. Different combinations of FSO and mmW transmission links had been proposed in the past for various application scenarios like hybrid link for airborne applications [7], ad-hoc mobile networks [8] and terrestrial and space applications [9]- [11]. The idea behind using such a hybrid network is to utilize the potential of the backup link when main link is not fully functional.…”

Free Space Optics (FSO) or optical wireless systems provide high data rate solution for bandwidth hungry communication applications. Carrier class availability is a necessity for wide scale acceptability which is extremely difficult to achieve in the case of optical wireless links. FSO links are highly weather-dependent and different weather effects reduce the link availability. Employing a hybrid network consisting of an FSO link and a back up link in the GHz frequency range renders high availability besides providing comparable data rates. In this paper effects of fog, rain and snow on FSO/GHz hybrid network are studied so that GHz frequencies with best complementary behaviour can be selected as a back up link. As a prime conclusion of the article, it is suggested that free space optical links can be supplemented with 40 GHz RF links to achieve near carrier class availability.

“…At first priority level the traffic is scheduled according to single class fair queuing model. The first priority is sensitive for delay ,the cycle time we use will be 2ms [1][2][3][4][5] .As we know the acceptable delay time for CBR is 5ms, so maximum cycle time, the CBR traffic can wait for 2 and ½ cycles. The capacity C is give by…”

In this paper we proposes a novel Passive Optical Network (PON) based broadband wireless access network architecture to provide multimedia services (video telephony, video streaming, mobile TV, mobile emails etc) to mobile users. In the conventional wireless access networks, the base stations (Node B) and Radio Network Controllers (RNC) are connected by point to point T1/E1 lines (Iub interface). The T1/E1 lines are expensive and add up to operating costs. Also the resources (transceivers and T1/E1) are designed for peak hours traffic, so most of the time the dedicated resources are idle and wasted. Further more the T1/E1 lines are not capable of supporting bandwidth (BW) required by next generation wireless multimedia services proposed by High

This paper proposes a novel Ethernet-based wired/wireless broadband access networking architecture that utilizes the existing wired trunk feeder fiber of typical PON (passive optical networks) infrastructure along with a hybrid FSO/RF (HFR), reliable wireless connectivity to the end users. The proposed architecture reduces the cost drastically as compare to conventional PON and provides 99.999% availability at range of 1 km in all weather conditions [1]. Most of the previous work on HFR has only considered point to point communication links, where the main objective was to increase maximum distance covered by HFR link [2][3][4]. The proposed architecture is point to multipoint HFR networking architecture and to the best of our knowledge, is the first work that considers HFR in a networking environment to provide broadband access to the end-users. This is extension of our previous work [5] to provide QoS (Quality of Service) to end users.
