WIRELESS POINT TO POINT LINK (WPPL)


Point to point wireless Ethernet bridge, also known as fixed wireless backhaul, PTP wireless, or point to point microwave, is an ideal complement or replacement to leased lines and fiber. Whether the requirement is to link individual buildings, communicate between buildings, or link networks across large distances, organizations are increasingly turning to point to point wireless backhaul networks, both licensed microwave links and unlicensed wireless bridges, as the preferred solution. Point to point wireless backhaul provides several advantages: Increase Bandwidth - Up to Gigabit data/voice links (gigabit wireless) Extend Fiber & T1 Installations Lower cost of installation No recurring connection fees Reduce leased line dependency Quick installation—days instead of weeks or months ROI - Cost can usually be recouped in months Performance unaffected by environmental factors Advanced Security - DOD and HIPPA compliant 99.999% Reliability Because there are no recurring lease fees to a phone company or service provider, outdoor wireless bridge networks in a point to point wireless backhaul configuration saves you money month after month. That, along with the modest cost of the outdoor wireless bridge equipment, is one reason that point to point wireless backhaul costs can be rapidly recouped. Once the wireless bridge equipment is installed, you own it and there are no other costs other than minimal routine maintenance. Point to point microwave radios provide high quality network connectivity. Point to point wireless bridges can be both simple and inexpensive unlicensed wireless Ethernet bridges or true carrier grade (fiber replacement) licensed microwave links




POINT TO MULTIPOINT WIRELESS


Outdoor point to multipoint wireless backhaul systems offer today's most flexible,economical, and easily deployed solutions for connecting multiple remote sites to the network. Point to multipoint wireless backhaul systems are ideal for interconnecting campus buildings, security systems, control systems, IP video surveillance cameras, WISP applications, integrating remote business sites, or installing last mile connections. Point to multipoint wireless Ethernet bridges are generally in the 900MHz, 2.4Ghz, and 5GHz ranges. These systems can provide DSL equivalent up to 170+ Mbps aggregate throughput. They are generally used where bandwidth requirements are generally lower and provide great DSL/T1 replacement. The range can extend as far as 10 miles, with optimum performance in the 1 to 2 mile range. Point to multipoint wireless backhaul systems are made up of a Base Station Unit (BSU or AP) that can communicate with multiple Subscriber Units (SU's). Many systems can handle over 100 plus SU's per BSU. In most cases the BSU's provide a sector antenna beam pattern (typical is 60 degree, with some systems allowing external antenna configurations for expanding to 90 and 120 degree sector antennas). Multiple BSU's can be installed to create a 360 degree sector (like a typical cell site configuration).




WIRELESS VIDEO SURVEILLANCE


Wireless Video Where You Need It!
The convergence of video surveillance and IP networking technology has lead to the prevalent use of computer based video and access control security systems operating on IP network infrastructure. Wireless backhaul, also known as fixed Ethernet wireless bridge, networks significantly reduce the cost of this infrastructure by either eliminating the need for structured cabling or augment structured cabled cctv networks by expanding the reach of the network parameter that cannot be reached easily by structured cabling.
Organizations of all verticals, from retail, education, to government organizations are being challenged to install outdoor video surveillance in areas that are too remote, too costly or physically impossible to reach with traditional cabling or fiber (wireless last mile applications).
Outdoor wireless bridge backhaul of video surveillance and security solutions allow for the wireless backhaul of high-resolution, real-time video surveillance from an unlimited number of video surveillance cameras and control systems. Wireless backhaul solutions can be deployed quickly and cost-effective. Video (cctv or IP) cameras, along with other security monitoring systems, can be transferred over point-to-point wireless, point-to-multipoint wireless, or wireless mesh backhaul systems. Wireless video surveillance solutions can be used in permanent fixed wireless backhaul, a temporary wireless video system, or mobile applications with wireless mesh.
Because wireless backhaul allows for quicker and more affordable deployments, organizations can scale their coverage needs and relocate systems as needs change. Even over vast distances an organization can deploy wireless video surveillance equipment.

GPON - GIGABIT PASSIVE OPTICAL NETWORK


A passive optical network (PON) is a network architecture that brings fiber cabling and signals to the home using a point-to-multipoint scheme that enables a single optical fiber to serve multiple premises. Encryption maintains data security in this shared environment. The architecture uses passive (unpowered) optical splitters, reducing the cost of equipment compared to point-to-point architectures. The GPON (gigabit passive optical network) standard differs from other PON standards in that it achieves higher bandwidth and higher efficiency using larger, variable-length packets. GPON offers efficient packaging of user traffic, with frame segmentation allowing higher quality of service (QoS) for delay-sensitive voice and video communications traffic. Gigabit PON (GPON) is currently the most widely deployed TDM PON system around the globe. Some operators are migrating BPON to GPON, or still rely on the performance of GEPON. The main features of a TDM PON network are the fiber architecture, which is based on a power splitter, and the time multiplexing of user’ traffic. In other words, not only the fiber architecture but also a single wavelength channel is shared between users connected to a PON. It makes GPON more cost-effective in several ways compared with other FTTH technologies. The broadcast nature of the network naturally allows for the deployment of television services such as CATV and IPTV.

Architecture

The optical power splitter used in GPON is defined to have a maximum split ratio of 1:128 so expenses are shared between a huge amount of users In practice, the maximum allowed number is limited by the link budget which basically boils down to the amount of optical losses introduced by the power splitter. A typical deployed split factor is 1:32; a result of a trade-off between distance between the home and the splitter and the number of homes passed. A frequently used option by operators is to split in sub-stages such that the network is deployed more efficiently and is more robust to bandwidth growth. In that case, splitters with smaller split ratios are used in intermediate stages. Technology

The GPON standard is issued by the ITU under ITU G.984 and several amendments have been made. The line rates are 2.5 Gbps and 1.25 Gbps in the downstream and upstream directions, respectively. The GPON data packets are sent time-division multiplexed (TDM) onto the network and the total available bandwidth is shared following the dynamic bandwidth assignment (DBA) protocol. It has concurrencies with the Gigabit Ethernet PTP wavelength allocation scheme because the 1310, 1490 and 1550-nm channels are occupied in GPON for upstream, downstream, and CATV overlay transmission. The GPON line cards typically hold 8 OLT ports and the number of line cards per chassis can be well above 10. It is clear that several 1000’s of users can be served by a single OLT; however, one has to work with high oversubscription factors to be able to offer high bandwidth connectivity.
