Read today in the papers about Digicel looking into data services. I don’t think they are talking about becoming an ISP but rather building a high speed data network on top of their transmission towers which space can be leased out to banks and ISP’s as well. Here is the article below:

(22/11/07, Post courier) Digicel faces row

Embattled mobile phone company, digicel’s latest move to provide data transmission is set to re-ignite the mobile phone saga. The company yesterday fended off claims its move to provide data transmission was illegal but that appeared to contradict the National Executive Council’s decision for it to provide only mobile services.

Digicel chief executive Kevin O’Sullivan told reporters on Monday that the company will spend $US25 million (K73 million) to construct SDH (synchronous digitised hierarchy) facilities to provide the transmission of data, something it is understood state-owned telecom company Telikom has the sole right to provide.

“We are going to build a high capacity SDH transmission link. It is like building an eight lane highway all over Papua New Guinea, eight lanes each way from a data transmission perspective. Is Digicel selfish to itself? No, we are going to provide access to this eight lane highway so that this means banks, ISP’s and other businesses can access transmission”, Mr. O’Sullivan said.

The cooled-down saga could re-ignite if that data transmission is constructed because State Enterprise Minister Arthur Somare last month in a media conference said neither Digicel nor Green Communications would provide services except mobile phone services. “When we introduced competition under NEC decision 25, [that] decision was specific that it would be for the mobile segment only”, he said.

—————————————————————————–

Another war may erupt, but it will all come down to classifications of services and line drawing in the sand. The way I see it Digicel is making the business case of maximizing returns on their investment into communications infrastructure. All the towers being built and setup across the country need to be used to their fullest capacity so how better to do that then to introduce more services on the network.

But just because they build a wireless network running on their towers does not mean that they are selling internet services. Because if they are talking about opening the network to ISP’s and banks to use their network, then technically they are just a pipe and not the source of data. Countless businesses in PNG have Wide Area Networks in place, even the banks with their ATM’s is a form of a data network, but they are all not selling data transmissions. All internet still ultimately comes from Telikom, it then goes to the ISP’s then on to banks, big companies, us etc. So I imagine that will be the same here in that data running off the Digicel network will have been initially bought from an ISP.

If on the other hand Digicel buys an ISP licence to sell internet access, then I can definitely see a war erupting. Even if they are acting like the current ISP’s by buying internet off Telikom first, I can see the ISP’s jumping up and down about this because they will be disadvantaged by Digicel’s reach, (but that will be another argument and we’ll cross that bridge if we get to it).

So what is this SDH?

Synchronous Digital Hierarchy is a data/voice transmission standard that was developed to allow for a more efficient transportation of voice calls along, say for our case, Digicels transmission towers. Which means you should think of SDH as a generic and all-purpose transport container for moving both voice and data, because the basic format of an SDH signal allows it to carry many different services because it is bandwidth-flexible. The main advantages of it are as follows:

1. High transmission rates
Transmission rates of up to 10 Gbit/s can be achieved in modern SDH systems. SDH is therefore the most suitable technology for backbones, which can be considered as being the super highways in today’s telecommunications networks.

2. Simplified add & drop function
Compared with older systems, it is much easier to extract and insert low-bit rate channels from or into the high-speed bit streams in SDH. Which means cheaper and faster access for say banks linking to the system if they were to use it for their ATM’s

3. High availability and capacity matching
With SDH, network providers can react quickly and easily to the requirements of their customers. For example, leased lines can be switched in a matter of minutes. The network provider can use standardized network elements that can be controlled and monitored from a central location by means of a telecommunications network management (TMN) system.

4. Reliability
Modern SDH networks include various automatic back-up and repair mechanisms to cope with system faults. Failure of a link or a network element does not lead to failure of the entire network which could be a financial disaster for the network provider. These back-up circuits are also monitored by a management system.

5. Future-proof platform for new services
Right now, SDH is the ideal platform for services ranging from POTS, ISDN and mobile radio through to data communications (LAN, WAN, etc.), and it is able to handle the very latest services, such as video on demand and digital video broadcasting via ATM that are gradually becoming established.

6. Interconnection (yes that’s the one, the big question on our minds)
SDH makes it much easier to set up gateways between different network providers, like (yes you guessed it), Telikom. The SDH interfaces are globally standardized, making it possible to combine network elements from different manufacturers into a network. The result is a reduction in equipment costs for everyone from Telikom to GreenCom to Banks etc.

So what’s in it for us?

Well better, efficient banking systems hopefully, so that we can use EFTPOS cards in small towns without the system ever going down. Maybe accessing internet in the villages, so that PNG can finally get on board the information superhighway in a BIG way. Internet on mobiles, iPhones, ringtones and so on and hopefully all at prices that don’t send us to the poor house.
