Basic Description:

LigoWave offers public safety officers a seamless 4.9 GHz point-to-point bridge solution with the release of the LigoPTP 4-19/4-N integrated backhaul device. Designed with mission-critical reliability in mind, the 4.9GHz wireless, point to point bridge 4-19/4-N delivers true TCP throughput up to 40 Mbps, at a packets-per-second performance of 50,000 PPS.

Even in challenging RF conditions, the 4.9GHz wireless bridge provides unparalleled performance by combining robust hardware technologies and unique, industry-leading software mechanisms. The LigoPTP 4-19/4-N product is perfect for public safety applications, delivering wireless dedicated access or backhaul solutions for police and fire departments, search and rescue teams, and other government agencies.

The LigoPTP 4-19/4-N product features an integrated 19 dBi panel antenna, with narrow beam width to enable long-range, rock-solid link connectivity.

The LigoPTP 4-19/4-N showcases an array of advanced software mechanisms that provide optimal point-to-point connectivity for high-throughput, long distance links. LigoWave’s proprietary PTP mechanisms utilize techniques such as Dynamic Time Division Duplexing (TDD) to dynamically allocate bandwidth in the direction needed, thus increasing link efficiency and greatly decreasing the impact that distance has on throughput of the link. The LigoWave point-to-point products also feature selective repeat ARQ technology, an enhanced error-correction software mechanism that optimizes data traffic to provide reliable, very high throughput over high-bandwidth, long-range links even in the presence of interference.

The LigoPTP 4-19/4-N is also compatible with RCMS, a centralized configuration, firmware, and statistics server offered by LigoWave for carrier class diagnostic and configuration management capabilities.

Connection to Network:

To connect the access point to your network at each location, a single Cat5 Ethernet cable is used.  A 50ft. cable is included for each location.  (If you need more cable, a maximum length of up to 200ft. can be used)  The Cat5 Ethernet cable connects directly from the outdoor access point using a weatherproof grommet,  to an indoor POE (Power-over-Ethernet) injector.  The POE injector plugs into a standard AC outlet for power, and another Cat5 Ethernet cable connects from the POE injector to your network (Router/PC/Switch etc.)

At the MAIN location, you will typically connect to an open LAN port on the back of your existing router, or switch.  At the REMOTE location, you can connect either directly to a PC if you only have a single computer, or you can connect to an indoor wired/wireless router.  This will allow you to run multiple computers over the wireless bridge.  See Diagram below.

Maximum Range & Interference:

With clear, un-obstructed line of sight between your two locations, a maximum range of 3 mile can be achieved using this link.  Please note that this Point to Point Wireless Bridge operates between 4.94-4.99GHz.  If you plan on installing more then one link at the same location, you want to avoid interference between each Point to Point link by using separate channels. Mount the outdoor access points as high as possible to further avoid any other 4.9GHz interference.

Each access point has a 24dBm maximum output power.  This works great for long distance Point-to-Point applications, as well as Client applications.  Power can be scaled back for closer installations to avoid noise issues and to meet local regulatory requirements.

For applications that require transfer of very large files, video transmission, or large amounts VoIP (Voice over IP) traffic, it is recommended that you choose a FULL DUPLEX, 5GHz Point to Point link, which will not only avoid all 4.9GHz interference, but offer much faster throughput, and lower jitter rates.  A full duplex, Point to Point Wireless Bridge will also offer lower latency, which increases performance.

For distances less then 3 miles, use the following full duplex link: GNS-LIGOPTP-PRO

Security Features:

This Wireless Point to Point bridge operates as a transparent bridge.  It is similar to an invisible Ethernet cable connecting your two locations.  It includes multiple security options including WEP/WPA/WPA2.  It also has ability to enable MAC address authentication so that only the two access points are able communicate.  You can hide the network SSID, and because the beam width of the antennas is directional, (about 16°) the signal is not being broadcasted in all directions, only in the direction you aim the outdoor antenna.

• More Robost Routing Features:  Includes Tunneling Protocol Support, which will allow you to pass through VPN clients, as well as use tunneling protocols such as VPN, PPTP, RSA and others.

• All New Access Point Features:  WDS will allow this Outdoor Access Point to be wirelessly connected to other Access Points, while still servicing clients.  (Wireless Distribution System)

• Wi-Fi Protected Access (WPA):  Wireless Protected Access improves on the security features of WEP.  It includes improved data encryption and user authentication, and AES Encryption.

• All New Client Adapter Features:  With this Outdoor Access Point, you will be able to align your client and point-to-point installations without having to log into the radio.  You will get visual signal strength at a glance by using this great new feature, using the alignment LED's located on the back of the Access Point.

• Controllable High Gain Output:  Both radios have 24dBm maximum output.  This works great for long distance Point-to-Point applications, as well as Client applications.  Power can be scaled back for closer installations to avoid noise issues and to meet local regulatory requirements.

• Wireless Security:  WEP, WPA wireless security is included in this wireless backhaul.  This will encrypt the data being sent between the connection.  Also included in this wireless backhaul is AES encryption, which is a higher level security feature then standard WEP/WPA.  The two radios can also be configured in PXP mode, which enables only the two outdoor access points to communicate with each other, avoiding any other access to the network.  The wireless bridge operates seamlessly as a Wireless Bridge between your two locations.

• Wireless Interference:  This wireless Ethernet Bridge is operating at 4.9GHz.  At most locations, this frequency is used less frequently then the standard 802.11b/g, so interference is usually minimized.  If you experience interference at this frequency, check that your antennas are not mounted directly on a metal surface, have line of sight between each other, and try changing the channel to one that is available .

When connecting the Outdoor Cat5 Ethernet cable to the access point, the below image will illustrate how to feed the cat5 cable through the weatherproof adapter, and into the Ethernet port on the access point.  Once tightened, this will provide a weatherproof seal for the RJ45 connector.  Please contact us with any questions.
