• Point-to-Point (PTP)

A point-to-point RF (radio frequency) network is the simplest form of wireless network. A point-to point link is comprised of two radios in "line of sight" direct communication with each other with a dedicated bandwidth. Point-to-point links are ideally suited for high-performance, dedicated corporate  connections, high-speed inter-nest links or backup/back-end applications. These links are generally quick to deploy but usually require professional RF design, planning and installation.

 

Point-to-point radios are available in several licensed frequencies and in the unlicensed ISM (2.4/5.8GHz) bands, and can achieve distances of up to 50 miles. ISM stands for Industrial, Scientific and Medical band, a part of the radio spectrum that can be used by anybody without a license in most countries.

 

License free and licensed frequencies both have benefits:

License Free Radio Frequency

 

-  Low cost

-  Fast deployment – no licensing

-  Replaces local loop

-  Own equipment - No monthly fees

-  Long range – up to 40 miles

-  Bandwidth up to OC-12

-  Repair time of 4 hours or less

-  99.999% uptime under most conditions

Licensed Radio Frequency

 

-  High Bandwidth capacity – up to OC-12

-  Long Range up to 40 miles

-  Interference free

-  Repair time of 4 hours or less

-  99.999% Uptime under most conditions

Point-to-point applications and users include cellular/PCS base station backhaul, last mile provisioning, private network interconnect, utilities, business enterprises, disaster recovery and LAN/WAN/Internet connectivity.

 

 

 

 

 

 

 

 

 

 

 

 

 

• Point-to-Multi-Point (PTMP)

A Point-to-multipoint RF network consists of a base station or access points at a central or hub site and multiple client or subscriber radios at remote sites. PTMP networks are connected in a star topology and bandwidth is shared between the remote subscribers. Typically, point-to-multipoint networks are easier to deploy than a point-to-point network because adding a remote user usually requires new equipment only at the user's site, not the base station or access point. Point-to-multipoint networks are used for indoor wireless LANs (WLAN) as well as an array of outdoor applications.

 

Point-to-multipoint networks are used for residential and business ISPs, educational and business campuses, indoor wireless LANs and various outdoor applications.

Benefits of PTMP

 

-  Replaces local loop

-  Own equipment - No monthly fees

-  Ranges up to 20 miles

-  99% uptime minimum

-  4 hour repair time

-  Bandwidth up to 20MBps

-  License free

 

 

 

 

 

 

 

 

• Mesh Networks

Much like the point-to multipoint networks, mesh networks utilize a base station radio or access point at a central network location, as well as multiple remote client subscriber units to distribute Internet and network access.

 

Mesh technology enables network operators to provide access to subscribers that may be obstructed by outside elements, buildings or other obstacles preventing direct communications with the base station access point. Each remote unit not only provides Internet access for the attached subscriber, but it also becomes part of the network infrastructure, acting as an access point extension to further distribute or extend the network service. Traffic can be routed through the network over multiple hops, allowing subscribers who may be out of range, or those with no line-of-sight to the access point, to join the network. The mesh networks are ideally suited for dense subscriber environments, for filling in shadows for ISPs, or for reaching subscribers that may have line-of-site issues.

 

Customer applications include small-to-medium-sized ISPs, multi-tenant or multi-dwellings, and business/educational campuses.

Today, PTMP and Mesh Wireless Networks are being used more and more for public safety, operations and homeland security applications in local, county and state governments.

• What are the benefits of wireless over wired?

-   Wireless is immediately available. Most

    wireless systems can be installed and

    operational within several hours and usually does 

    not require expensive excavation or related work.

 

-   License-free frequencies are available at no cost

    to anyone desiring to deploy a wireless broadband

    network.

 

-   Licensed frequencies, if required, may also be

    obtained by end users or carriers.

 

-   Copper and fiber connections usually require

    monthly leased line fees paid to telephone

    companies, whereas operators of wireless

    broadband networks can own and operate their

    own wireless infrastructure.

 

-   Wireless systems can offer a quicker return on

    investment versus a wired solution ROI. Further, 

    most wireless systems can be deployed at lower

    costs and are often more reliable than copper

    or fiber.
