Former European cable execs see BPL parallels
Tom Walsh and Patricia McGrath were executives at UPC Broadband — now owned by Liberty Global. The Netherlands-based firm grew from a 200-user cable modem trial network in Amsterdam in the mid 90s to a customer base of over 1.5 million cable broadband subscribers in 14 countries in 2002. Walsh was vice president of engineering and then operations and McGrath was vice president of network planning and implementation.
The two left UPC and in 2005 they started Glasnua Ltd. in Ireland. They looked at various alternative technologies and soon found BPL. Glasnua, are convinced BPL is the technology it had been looking for and set its sights on deploying BPL for utility services and retail triple play throughout Europe .
Walsh and McGrath spoke to us Thursday from their headquarters in County Kerry in Southwest Ireland .Walsh is CTO and McGrath is director.“ Europe will offer incredible opportunity for ‘smart grid’ technology players for the next 10 years,” said Walsh. He believes the key for BPL technology firms to succeed in Europe will be to maintain a presence without draining resources and funds.
www.glasnua.com is set up to help. The firm’s been trying to land BPL projects with utilities but like everywhere, European utilities have resisted.
EU’s pushing BPL
“Utilities have been slow to come to the table so far — but here in Europe the EU is actively pushing the technology,” said Walsh. Why is the government of Europe pushing BPL?
A BPL initiative is underway to “overcome the energy challenges presented by a rapidly expanding [EU] membership where demand is outstripping supply,” Walsh reported. He and McGrath are involved in that government effort and they’re confident “it will happen,” she added. The firm wants to introduce to Europe some of the main players in the BPL world “that have existing and proven technologies and proven business cases so that we can jump start some technology trials.
“We believe that some of the strongest players have a great opportunity to be in at the beginning” — with a real possibility to turn those trials into commercial deployments.
Glasnua hopes to avoid “open-ended science experiments — that I think have been some people’s experience in the past,” said McGrath. Some of the utilities in the EU are trying to “reinvent the wheel,” she added — and Glasnua wants to show them wheels are “already out there,” she added.
The challenge for Glasnua is to make deals with international BPL technology firms including US firms and represent them in Europe.
The name says it all
Glasnua learned early that utilities aren’t usually interested in hype about the broadband business. True to its name, the firm is focused on utility applications and sees that market offering huge potential. Commercial broadband is a side benefit that can be delivered by firms that lease bandwidth from the utility, he noted.
But the need for the 21st century smart grid is urgent. The EU grew from 15 to 27 countries in the last 3 years, Walsh reminded. Many have rapidly growing economies that are putting incredible demand on power grids.
These states have limited raw resources for energy production and a lack of organization in the power interconnection between countries. The EU doesn’t have a system to manage the grid or know “who’s producing power” and who’s using it.
“Smart grid efficiency and control are finally being seen as the way to integrate and manage the various networks” — and cut reliance on generators outside the Union, said Walsh.
Meanwhile less developed nations in the EU are trying to build their economies and getting access to broadband is a key ingredient. “Pilot projects are being planned to take the best existing solutions and test them for commercial roll-outs throughout Europe.”
Walsh expects BPL’s role to expand as green power generation projects such as home-based generation, solar panels, wind farms, tidal power and more start populating the grid. Interconnection with those projects will make managing the reliability of the grid ever more complicated — and some look to BPL as an obvious answer to managing that complexity.
They saw cable get smart
BPL reminds Walsh of the early days of cable. People in 1997 told him cable modem networks “couldn’t happen, it wouldn’t work — we were dreaming.” BPL is in roughly the same position as cable was then — with a lack of standards, some engineering challenges in creating networks plus it’s got its nay sayers.
The broadband boom in Europe was similar to “the wave that’s building for smart grids. ”Cable traditionally was a one-way, wire-based distribution network. Sounds familiar.
Cable modem technology introduced tremendous advantages by adding IP to those networks.
Suddenly the operator could see the condition of every piece of gear on the network all the way to the customer’s modem.
That gave Walsh a brand new kind of power in making financial decisions. He could make choices on where to spend money on the network — based not on which technology officer in field wrote the most compelling request, “but on actual live statistics,” he stressed.
His operational crews — that had only ever been reactive — could now act proactively based on real-time data and “before stuff breaks.” Walsh would set targets and key performance indicators for his managers and then “see how they were doing — not based on a score card but actual real statistics, real facts.” www.glasnua.com
QUOTE OF THE WEEK: All of a sudden you had huge efficiencies coming into the operation which means you gave better end-service to the customer. At the same time you were able to reduce costs of providing the service. This was all happening in the cable sector probably in the years of 2002, 2003. Take that benefit and combine it with BPL and you are making that business case look much rosier.
Tom Walsh, CTO, Glasnua
These folks have scaled
Another similarity with cable is the problem utilities face in scaling data networks to cover entire utility footprints. Those are the same problems Walsh tackled with cable-based broadband, he reminded.
It takes “business nerve” to wait for the opportunities to ripen — and then capital to take advantage of the moment when it’s right.
Superior technology will win out, he added. “For us, ‘smart grids’ is nothing new. www.glasnua.com/aboutus.html
“We deployed similar technology on communications networks and quickly realized the operational benefits when scaling is handled correctly.”
“The smart grids principle is not new. “It’s been [used] in the telecom sector for over four years and has revolutionized both technical and operational management.
“These benefits can now be realized by power utilities, too”

Voice over Internet Protocol (VoIP) is an amazing new technological communication tool to take the world by storm. It is increasingly gaining popularity owing to the advantages it provides to every user. Many businesses these days are switching to using VoIP as it helping these organizations stay abreast of many a competitor at the same time has helped bring expenditure for communication to a lower level.
If you are running a business, you need to be in constant touch with your clients. By communicating with the clients on a regular basis, you are trying to convey that the services you are providing are the best in the industry and you are also trying to improve business by making your clients aware of new products or services you have added to your existing portfolio. A way to go about achieving this is to establish a help desk or a hotline catering to customer service.
Having a helpdesk necessitates you to have a line to communicate with your clients. For this you require to have a proper communication tool to achieve this. The internet is a total tool to help you out with all your communication needs. One way to keep in touch with all your clients is through email. But, email cannot be used in all communication and cannot help out in every circumstance.
Another powerful tool that will help you meet your business communication needs is the new technological advance called VoIP or Voice over Internet Protocol. This, like the regular telephone, will help you communicate with your clients directly but unlike the conventional landline uses the internet to send and receive signals. Here, instead of analog signals the VoIP system uses digital signals to relay data. Even though digital format has been used for conventional telephones through fiber optic cables, VoIP uses the Internet to send the data and is more proficient.
VoIP offers a host of added advantages that benefits every user of the system. As the mode of transmission is through the internet, VoIP costs quite less in comparison to the conventional landline. One has to just invest in the basic infrastructure initially and then get to enjoy the benefits of its low cost thenceforth.
In addition, VoIP provides other added features that subscribers can get for free. Some such features include caller ID, call forwarding, call waiting, three-way calling, etc. Many such features are offered while a subscriber opts for a standard pack. Some other features like video conferencing can be opted for by an user through VoIP and these features are not provided by the regular landline phones.
Having such added features will definitely help a lot in meeting your business communication needs. Opting for VoIP as the means for communicating with your clients will definitely be a cheaper option. You also have the option of choosing an area code to suit you. This means that you can be having your business in one area but be using the area code of the area you choose which is beneficial to clients in the area code you have chosen because they will only be charged for local calls and will not have to bear any higher call rates.
VoIP has become increasingly popular means of communication for business organizations. This system will not only help in cutting down expenses to the organization, it will help in easing many tasks as it provides many value added benefits and features like customer service, email, video conferencing, voice mail all integrated in a common network.
Business owners can get great benefit by using VoIP for all their data networking needs. This enables the organization to stay in contact with its clients yet save a lot for the company. Also, users get to enjoy free features that are not available through the regular landline.
Business communication needs and data networking can be integrated to a common platform using VoIP. Various aspects of data networking like accounting, customer services and filing of data, etc can be united into a single channel i.e. VoIP.
It is time to stay abreast of your competition yet be able to cut down on expenditure using VoIP for your data networking needs. Choose a service provider who is the best in the business to enable you to get the greatest advantages and features that you can get through VoIP. VoIP is the way to go to make your business stronger and more successful.

A Network Attached Storage (NAS) is a type of storage system that can be attached to a data network. A NAS is useful for storage related to non mission-critical data. It is cheaper and easier to maintain than a Storage Area Network (SAN) but does not quite deliver the performance an enterprise can obtain from a SAN.
File transfer protocols supported by NAS include Network File System, Common Internet File System, File Transfer Protocol, etc. NAS servers offer flexibility in terms of attachment to the network; this can be done either via the Ethernet or a fiber channel network. These days you can also get wireless 802.11 NAS devices. The beauty of NAS devices lies in their simplicity, they can be built using any disk technology though they are usually developed using Small Computer Systems Interface (SCSI). NAS devices can also be used for other storage methods such as magnetic tape, CD, and DVD.
NAS offers the following advantages –
1. Faster access to stored data via the LAN.
2. Low costs since the RAID arrays are a part of the LAN.
3. Easy to install, can be up and running in less than thirty minutes.
These properties of NAS storage plus its low cost of ownership make it ideal for SMBs. A dual advantage of NAS is that it allows administrators to either increase or consolidate the storage infrastructure. Storage expansion is virtually unlimited as one is freed from the limitation of storage capacities of individual servers and the number of disks they can hold. At the same time, one NAS set-up is good enough to replace several file servers that are operating individually, this leads to consolidation. NAS can be run on commonly available operating systems such as Windows. NAS status can be checked from anywhere on the LAN, this gives storage administrators the ability to diagnose issues and change NAS configurations when required.
NAS system performance depends on the drive support, the number of drives in use and the overall capacity. SATA drives that offer excellent low-cost bulk storage are most preferred. SCSI drives are also available. Since the NAS makes use of the LAN for data transfer there is always a chance of a bottleneck developing somewhere along the LAN, usually it is the network interface that causes problems. If implementing a NAS, look for products that support Gigabit Ethernet for quick data transfer and multiple connections so that network load is distributed and interface redundancy is provided.
When purchasing a NAS solution always keep security in mind and look for vendors that offer native encryption with the system.
