Enabling the last mile for broadband communication

What can we do when our broadband network is at one central place and we want to extend it to other places nearby, place too far away for normal wireless connection.
It can be used to extend your own LAN to a remote place or transfer a single point of internet access to other buildings.

There are 4 main solutions for connecting nearby places wirelessly:
1. Standard wifi B/G/N… technology – this technology is good when you need a connection inside a home and up to about 20 meters, due to walls that block the signal.
2. Wimax – well… no one knows the future of that technology.
3. Satellite communication – it’s OK if you have lots of money and want to connect a long distance points so the cost effective issue is addressed.
4. RF connection – you can convert the Ethernet protocol to RF (Radio Frequency), send it to longer distances then the standard wifi, convert it back to Ethernet and enjoy a reliable connection for longer distances (10000 feet and much more).

There are few manufacturers that make it easy to cover the last mile, manufacturers like ARCFlex technology from ‘ARC Wireless’ company and airMAX technology from Ubiquiti.
It is clear that the Ubikuiti technology gives a wide variety of solutions to get broadband wireless connection, working with no problems of speed and connections Interference for years.

airMAX® technology from Ubiquiti

The idea of RF connection is to convert the Ethernet protocol to RF and then send it wirelessly to long distance places, than convert it back to Ethernet and convert it to secondary LAN.
There are parts that do the conversion, the antenna and parts like a dish to extend the distance of the connection.
The working Ethernet interfaces are 10/100/1000 base-T and can reach a working bandwidth of 150Mbps for the end user.
The equipment needs to be safe and reliable to use in bad weather such as rain, strong winds, extreme cold and heat, because it needs to be placed outside 24/7.
With this technology, you can connect 2 remote LAN networks like point-to-point connection and also connect one LAN network to multiple remote LAN networks.
Trends on the wireless broadband networks:
1. New research from the Wireless Broadband Alliance shows that 57% of the operators intend to rule out carrier-grade wifi at some point. The research showed that by 2020, 80% of respondents plan to have deployments in the areas of IoT/M2M, and more than half have plans for converged services and Smart Cities.
2. On June 10, 2015 – Ubiquiti Networks, Inc. announced what is believed to be a new world distance record for wireless broadband. The 140 mile / 225 km link was established from Las Vegas to Los Angeles with a data rate of 155 Mbps with two airFiber® 5X radios paired with 31dBi antennas. This more than doubled Ubiquiti’s previous best og 64 miles / 103 km.
3. It is obvious that broadband wireless RF connection is an area that is being developed very fast, mostly due to standard wifi is not enough and Wimax technology did not take off as expected.

With this FR technology, before you run and buy the parts you must check a few things:
1. What is the weather at the place of installation – extreme conditions.
2. What is the distance between the points you want to connect – do you need hi DB amp or not.
3. Do you have a clear line of sight or have trees/buildings that will interfere with the signal.
4. What network speed you want to work with – not at the Ethernet side, rather on the converter side.
5. Do you have a pole on which the converter and antenna are installed on?
6. Use the recommended cables – low quality cables will result in reduce in amp db’s and connection problems.
7. Make sure you use lighting protection for the antenna and the system inside, the outer system can transfer a lighting through the cables or cable shield into the house.
8. If you have many sites, you can use devices with GPS integration so the timing on all stations are exactly the same – usually important in point to multipoint design for packet timing.

That is how to extend your network to places with no cable connection and are too far for standard wifi connection.
