Overview

Leaky feeder is an antenna technology originally designed to deliver radio services in tunnels.  If your car radio continues to work as you pass through a long tunnel it is likely that a leaky feeder installation is involved.

As its name implies leaky feeder is a cable which leaks a small amount of the radio signal throughout, just like a hosepipe with holes drilled at intervals along its length. Leaky feeder cable is also often called Leaky CoaXial or LCX cable.

At Solwise our interest in the technology stems from a number of WiFi installations where conventional access-point and antenna combinations have proved troublesome.  For instance, a hotel with long corridors and solid concrete floors and walls can require an access point in every room in order to ensure reliable WiFi for every guest. An installation such as this would be expensive in hardware costs, tricky to install and hard to manage and maintain. A traditional multi-AP type installation would also raise potential issues with client roaming and user confusion when they see several wireless networks.

A leaky feeder installation, perhaps in the suspended ceiling of the hotel corridor, can replace many access-points with just one, feeding a leaky cable over the length of the corridor.  The signal from the cable would pass though the wooden doors providing a service to every room. Using a single AP in this way makes the entire wireless network appear as a single WiFi network which greatly simplifies connectivity and roaming issues for the users.

Another example of a difficult WiFi installation is a warehouse or cold-store where stored product creates canyons into which radio signals cannot penetrate.  A leaky feeder cable above each canyon or hanging from ceiling joists can be a cost-effective one-stop solution.

This cable and the connectors are not compatible with the earlier versions of the cable and connectors. If you have the older cable in stock and require connectors for it, we do have a limited supply, please call in for details. The terminator works with both versions of the connector.

Please note, you will need a connector at each end of the cable. The terminator attaches to the connector, not directly to the cable.

Below shows a rough picture of how the signal would typically be propagated down a corridor if a multiple Access Point scenario was used.
Scenario with Access Points
Because of shadows caused by the walls of the rooms and corridor then coverage in those rooms out of line of site of an AP can be very poor. The red areas show where the signal is very strong but note the shadows where signal is not reaching.
 
Compare this with the sort of coverage an LCX system can provide.
Scenario with Leaky Feeder Cable
With LCX cable running down the ceiling of the corridor then coverage is much more complete. Basically any point that can ‘see’ the cable can receive a good signal.

From the above you can see, in a multiple AP setup, as long as you are in line of site of one the AP’s then you get an excellent signal; in fact a signal which is almost certainly much stronger than is required. On the other hand, with the LCX setup, due to the distributed nature of the signal from the leaky antenna then the signal is evenly broadcast down the entire corridor bathing the whole area in a medium gain signal. Although the absolute strength of the signal from the LCX is lower than that which might be given in direct line of site of an AP, the fact that the LCX system gives a higher coverage with much reduced shadow effects results in an overall much better solution.

Another example of a difficult WiFi installation is a warehouse or cold-store where stored product creates canyons into which radio signals cannot penetrate.  A leaky feeder cable above each canyon or hanging from ceiling joists can be a cost-effective one-stop solution.

Leaky Feeder & Grand Designs

A young couple want to take on an average 1950s house and turn it into an architectural masterpiece. These are the words of Channel4 and Grand Designs, where does Solwise fit into this kind of build?  Well, Ben and Rachel Hammond were looking to ‘future proof’ their new home and they decided that Leaky Feeder cable hidden in the ceilings was the way to go.

As with all these things, little is shown of the cables and hardware used in the background but if you watch the programme at the end where they show you around the finished project, see if you can spot the leaky feeder kit. You can’t, it is all hidden in the ceiling making for a beautiful finish to this lovely home.
