Sensitivity Analysis of Promotional Strategies Of Mobile Telephone Service Providers II

This year is the 30th anniversary of Telecom Australia's launch of the cellular mobile service in Australia. There has been a huge evolution in mobile services since then.The Postmaster-General's Department (PMG) introduced a manually (operator) connected mobile service in Australia in 1950. As this service approached full capacity, Telecom launched a Public Automatic Mobile Telephone Service (PAMTS) in 1981. The PAMTS service had no future technology evolution, a 12 year life, and reached a peak of 14,000 customers.By 1985 a small engineering team had developed a cellular mobile service concept based on the Analogue Mobile Phone Service (AMPS ) standard. Development was accelerated and refined and the service was launched in 1987, arguably two and perhaps three years late.This is the story of the development and launch of the service and the growth over the first four years to 1991.Noting the experience of cellular operators in the USA, Canada and the UK, Telecom's mobile service concept was a "gold standard" for cellular services around the world, and the service achieved one of the fastest growth rates in its early years.Within four years it was a cash flow powerhouse, and one of only three services within Telecom that were profitable; the others were the basic telephone service and directory publishing.When transferred to Telstra in 1992 it was a strategically strong, highly profitable business prepared to defend against competition being introduced into the Australian telecommunications market, and was a foundation of Telstra's financial strength for the next 30 years.

It is generally considered that remote and rural telephone users generate less traffic as compared to urban area users. This lowers the attraction of investment in rural areas by the telecommunications companies and service providers. The financial implications of wiring a vast area for low telephone traffic causes most telephone service providers to ignore those regions. Still, it is known that telecommunications are essential to the economic development of a region and that traffic increases rapidly as soon as the service is available. A satellite–based telephone network can provide efficient long distance telephone service to remote rural communities at a lower cost than land-based wired networks in most cases. Mobile satellite systems already provide this service, but are limited in capacity and charge high per-minute fees for the satellite link. Small earth stations and GEO satellites can provide this service more efficiently and at lower cost. On top of that, bandwidth efficient multiplexing with compressed speech, Voice Activity Detection (VAD) and Packet discarding methods can even further reduce the cost of service for the users in rural areas. In this paper, Statistical Time Division Multiplexer (STDM) architecture was simulated. Two packet discarding methods, random packet discarding and cyclic packet discarding are used to maximize bandwidth utilization along with VAD. Results indicate that considering monologue speech source, with 80%, activity for each 6.4 kbps sources, on a channel of 64 kbps, 12 users can be allowed to be multiplexed instead of 9, therefore a Digital Speech Interpolation (DSI) advantage of 1.33 is achieved with 3% packet loss. Furthermore, it is observed that cyclic packet discarding technique perform better than random packet discarding in terms of subjective quality

We use historical data to study the feature phone (as different from smart phone) years of the mobile phone industry. This study relates to the years 1994 to 2004, at a time when the industry grew to a landmark of one billion mobile phones cumulative sales worldwide. Actor Network Theory (ANT) is used as a lens to understand the key alliances between selected mobile phone companies and other actants. In line with ANT, actants include consortia, service providers, and IT vendors. The leading mobile phone companies- Nokia, Samsung, and Motorola, display a number of characteristics and actions that have implications for the current and future state of the market. The study demonstrates the explanatory power of ANT. It is important to understand the earlier years of the industry to understand its current state, particularly with reference to Nokia and Samsung. The notion of path dependence suggests that these actors continue to leverage, or be weighed down, by their strengths and weaknesses traced back in history to feature phone years.
