As new telecommunications services were developed and introduced over time, it was simpler for Service Providers to deliver them across individual networks. In recent years and, largely due to fi nancial pressures, Service Providers have converged their service backbones and delivery mechanisms to Internet Protocol (IP) platforms, gaining economies of scale and removing unnecessary duplication of links in their networks.

Figure 1 illustrates how services are typically delivered to homes today. Whilst there is some sharing of network infrastructure between voice and data getting to the home, in the home they are separate. Free to air and pay TV come in on different networks and terminate on the same TV device. Other services such as security, audio and so on could be added to this diagram, each having its own domestic connections.

The transformation of Service Provider networks to IP is now infl uencing the delivery of advanced

services in the home and in February 2011 the Australian Communications and Media Authority (ACMA) published a paper titled ‘Development in Home Networks’ which looked at the changing architecture of the traditional separate networks into the converged IP based Network. The paper stated that: “emerging IP-based services such as health monitoring, security, home automation, entertainment and social networking accessible via home networks are reshaping the user experience.”

We are now seeing this major shift, from separate networks, to a common IP transport platform delivering a multitude of services. This transformation is being fast tracked by the rollout of fi bre to the home in the form of the National Broadband Network (NBN), an initiative of the Department of Broadband, Communications and the Digital Economy. As the NBN is implemented, all service providers will deliver their services across the NBN using IP.

FIGURE 2 CONVERGED NETWORK

Figure 2 shows how the separate specialised networks are replaced by one that is horizontally integrated with all services using the same IP delivery mechanism. Unfortunately, while all services are delivered to the home via IP, the connectivity in the home between the service providers’ network and the home devices may be achieved by using any one or mix of the following technologies:

1. Wired – Fibre2. Wired – Cat 5 or 63. Power Line Communications (PLC)

(Ethernet Over Power Line)4. Ethernet Over Phone Line (Telephony

Twisted Pair)5. Ethernet Over Coax (Coaxial Cabling)6. Wireless (Wi-Fi)

The ACMA’s paper concludes that: “consumers will need to be more aware of technical aspects. Both industry and consumers will have a role in meeting this awareness through education to improve technical expertise and awareness of technological developments”.

How can we best support the consumer, so as to simplify the internal network in the home?

One starting point for this is the deployment of a homogenised connectivity, open platform using a structured cabling solution based on category 5 or 6 cabling, augmented by wireless for mobility. This makes the future management of the network simpler, allowing the partnership between the consumer and the contractor to grow. Whilst this is the utopian position achievable in new homes, this at face value is not as cost effective for existing homes.

It is therefore important to provide the consumer with a comparison of the range of connectivity technologies that are available so that they can make an informed decision.

ABOUT THE SOLUTIONS

The purpose of this section is to expose you to the range of connectivity technologies available for use in a residential home. So you can, in turn, advise the consumer. All technologies presented are viable solutions but it is important to make an informed decision as to which is the best connectivity solution for a particular application.

When looking at the best connectivity solutions for the home for the incoming and interactive services provided by the NBN, it is simpler to divide the home market into two main categories:

1. New or renovated homes2. Existing homes

NEW OR RENOVATED HOMES

The connectivity solution for a new home, or one that is being renovated, is best achieved through a hybrid of:

3. Wired (for fi xed location devices such as TV, alarm system, Smart Home controls)

4. Wireless (for devices mobile in the home such as laptops, phone handsets, tablet computers)

Note: While the connectivity solutions listed below can be used in a new home once it has been built, a wired solution included in the build is considered the optimum solution given the cost of installation is low if it is installed when the home is being built.

EXISTING HOMES

The connectivity solution for an existing home is a mixture of a much greater range of technologies, these being:

1. Wired – Fibre2. Wired – Cat 5 or 63. Power Line Communications (PLC)



What the consumer needs to know is exactly what each solution is and what are the benefi ts and disadvantages of each solution.

In this section we look at what you would need to establish a simple connection from the NBN’s Network Termination Device (NBN Box) using each of the above listed technologies. At one end we have NBN’s network termination device (NTD, sometimes referred to as Optical Network Terminal or ONT) and at the other end a computer as seen in Figure 3. (This is representative of any device with an IP connection).

For each technology, we show in red the connectivity solution in place from the NTD to the Computer.

SOLUTION

1Figure 4 shows the connectivity provided by fi bre. The full link consists of 5 elements. It shows optical fi bre running from the location of the NTD to where the computer is located, and the fi bre terminated on fi bre connectors. At each end of the fi bre is a media converter and then a cat 5 or cat 6 fl y lead from the media converter to the NTD or the computer. The media converter converts the electrical data signal RJ45 interface on the NTD to an optical signal for transmission over the fi bre and back again. The IP data interface at the computer is typically an RJ45 connector.

STANDARDS

The installation of this type of connectivity is covered by cabling standards and must be performed by a registered cabler. (See References Section for Standards)

ADVANTAGES

1. Dedicated link between the NTD and the computer and there is no bandwidth limitation due to the media type as fi bre will support well beyond 1Gbps.

The bandwidth is limited because of the media converter or computer Network Interface Card (NIC) but these are typically specifi ed at 1Gbps.

2. Highest security as the only way to intercept this link is physically.

3. Life cycle of fi bre is typically as long as the building’s life cycle.

4. Easy to use, no specifi c confi guration requirements, no password or encryption required.

DISADVANTAGES

1. Not good for mobile devices.2. Higher cost to install in existing home.3. If the cabling is installed in concealed

locations, it must be installed by a registered cabler.

4. Each additional device or location you want to add to the network requires a new cable to be installed.

5. The media converters need to be permanently powered and will require replacement on failure.

WIRED- CAT 5 OR 6

SOLUTION

2Figure 5 shows the connectivity technology used. A fi xed cat 5 or cat 6 cable with RJ45 sockets at both ends and a fl y lead at both ends to connect to the NTD and the computer. This link is composed of 3 elements, so the connectivity solution in this case consists of passive wire, sockets and plugs.

STANDARDS

The installation of this type of connectivity is covered by cabling standards and must be performed by a registered cabler. (See References Section for Standards)

ADVANTAGES

1. Connectivity is passive and therefore very reliable.

2. Dedicated link between the NTD and the computer so there is no bandwidth limitation. Typically 1Gbps, the only limitation is the speed of the interface card in the computer and the ONT.

3. Highest security as the only way to intercept this link is physically.

4. When not in use consumes no power.5. Life cycle of cable is typically as long as the

building’s life cycle.6. Easy to use, no specifi c confi guration

requirements, no password or encryption required.

7. Easy to fault fi nd as there are no active components in the link. So a problem is either in the NTD, the cable or the computer.

DISADVANTAGES

1. Not good for mobile services.2. High installation cost in existing home.3. If the cabling is installed in concealed

locations it must be installed by a registered cabler.

4. Each additional device or location you want to add to the network requires a new cable to be installed

POWER LINE COMMUNICATIONS (PLC) (ETHERNET OVER POWER LINE)

SOLUTION

3Figure 6 shows the 5 elements that go to make up the Ethernet over Power Line connectivity platform. In this case you need to have an adaptor at both ends that plugs into the existing power point, then a Cat 5/6 fl y lead from the adaptor to the NTD and from the adaptor to the computer. The fi fth element is the physical electrical cabling installation in the home.

STANDARDS

There is a range of vendors’ implementation of standards that compete with each other and care should be taken when choosing additional equipment. Over time there will be harmonisation but until this happens care should be taken on which standards to deploy.

DEVELOPING STANDARDS

This section lists the more current development of standards.

G.hn which is a new standard ratifi ed recently by ITU and supported by the Home Grid Alliance.

IEEE 1901 which is a formalised adoption of the original Home Plug standards

EXISTING STANDARDS

These are standards developed by alliances of companies promoting standardisation to allow for the creation of a new market.

HomePlug 1.0

HomePlug AV

HomePlug Green PHY

ADVANTAGES

1. Connectivity link utilises the existing electrical cabling installation.

2. Installation can be performed by the home owner.

3. Can provide temporary connectivity in rented homes.

4. No licensing requirements for installers.

DISADVANTAGES

1. The performance of the link is dependent on the electrical installation. As the electrical installation was not designed as a communications link, the actual transmission speeds (throughput) may vary from time to time and be signifi cantly lower than the predicted maximum of the adaptors installed.

2. If the power points used are on different power phases there may be limited or no connectivity.

3. As you add more adaptors the electrical cabling becomes a shared medium, resulting in lower throughput.

4. Whilst the adaptors use encryption for security, they are on a shared cabling infrastructure that extends beyond the home.

5. There are competing standards and chipsets so care should be taken when buying additional adaptors.

6. Whilst the theoretical number of adaptors that can be connected is large, this does not seem to translate well into a real life practical installations.

7. The adaptor takes up a power point, though some models have a “Pass-thru” power outlet to overcome this.

8. The adaptors need to be permanently powered and will require replacement on failure.

9. Fault fi nding can be more complex as there are more elements between the computer and the NTD.

10. Not best for mobile services, but the adaptors can be moved between power points as the computer is relocated.

ETHERNET OVER PHONE LINE(TELEPHONY TWISTED PAIR)

SOLUTION

4Figure 7 shows the 5 elements that go to make up the Ethernet over Phone Line connectivity platform. In this case you need to have an adaptor at both ends that plugs into the existing phone outlets, then a cat 5/6 fl y lead from the adaptor to the NTD and from the adaptor to the computer.

2. nstallation can be done by the home owner (assuming telephone cabling exists).

3. Can provide temporary connectivity in rented homes.

4. No licensing requirements to be installed.

DISADVANTAGES1. The performance of the link is dependent

on the quality of the telephone cabling installation. Some home telephone cabling installations could be decades old.

2. As you add more devices the phone cabling becomes a shared medium.

3. Each adaptor requires access to a power point as they are active devices.


5. Fault fi nding can be more complex as there are more elements between the computer and the NTD.

6. Not best for mobile services, but the adaptors can be moved between phone socket locations as the computer is relocated.

SOLUTION

5Figure 8 shows the 5 elements that go to make up the Ethernet over Coax connectivity platform. In this case you need to have an adaptor at both ends that plugs into the existing coax outlets, then a cat 5/6 fl y lead from the adaptor to the NTD and from the adaptor to the computer.

2. As you add more devices the coax cabling becomes a shared medium.

3. Each adaptor requires access to a power point as they are active devices.


5. Fault fi nding can be complex as there are more elements between the computer and the NTD.

6. Not good for mobile services.7. 7Care must be taken that any adaptors do

not interfere with any existing RF services which may already be using the coax cable.

8. 8Very complex to deploy in high rise apartments or any home which uses a shared television distribution system such as a mast-head distribution amplifi er or cable splitter.

WIRELESS (WI-FI)

SOLUTION

6Figure 9 shows a typical wireless connection which consists of 3 elements. The 3 elements are the fl y lead from the NTD to the wireless router, the wireless router and the link provided by the atmosphere. The wireless router is connected to the NTD and uses the computer’s wireless capability or interface card.

STANDARDS

Wireless standards have now been around for some time and the one dominant standard is IEEE 802.11 commonly referred to as Wi-Fi. There are specifi c vendor enhancements to this standard which claim to deliver higher throughput, but only between pairs of wireless components that support the specifi c enhancement.

ADVANTAGES

1. Easy to install.2. Ideal for all mobile devices.3. Very common support on portable devices.

DISADVANTAGES

1. Performance suffers as the distance from the wireless router increases.

2. Walls and fl oors can reduce performance or prevent wireless communications.

3. Performance may be variable due to interference from other wireless devices such as microwave ovens, blue tooth devices etc.

4. Wireless in adjacent high rise apartments can cause interference leading to variable and poor performance.

5. Wireless is a shared medium so as the number of devices increases, individual throughput decreases.

6. Requires security confi guration (Modern wireless routers support push button security enrolment).

7. The wireless router is active and powered with a power pack. Either device may be a point of failure and require replacement.

MULTIPLE CONNECTED DEVICES

So far we have considered only one device connected to the NTD. The question then arises, what happens when there is more than one device? To answer this question we can look at each connectivity option when more than one device is required.

The connectivity options are: 1. Wired – Fibre2. Wired – Cat 5 or 63. Power Line Communications (PLC)



NOTE

Whilst the NTD provided as part of the NBN roll out has up to four ports,

each port is likely to be assigned to a different service provider. For

example your ISP may be on port 1, your security may be on port 2 etc.

1. WIRED – FIBREFigure 10 shows multiple computers connected via individual fi bre links so every link has the full transmission capacity of the fi bre technology, which is easily 1Gbps. This involves two more media converters and their power supplies for each additional connected device.

3. POWER LINE COMMUNICATIONS Figure 12 shows multiple computers connected via PLC links. In this case every device connected via the PLC link is sharing the one resource, which is the electrical wiring. The maximum transmission speed to each device will vary depending on the number of devices sharing the wiring. The number of adaptors will vary with the number of computers as this technology supports “one to many” connections from the one adaptor at the NTD to the many at the computers.

IN SUMMARYWhen the number of users increases, the link speed to each user on fi bre and UTP cabling system will not change.

When the number of users increases, the link speed will be adversely affected by the number of users, when using PLC, Ethernet over Coax, Ethernet over Phone Line or Wireless.
