The Data Communication Scene in Pakistan

Article excerpt

A lot seems to be happening on the national scene related to Data Communications. Things are expected to happen in the near future that would make most of the users of Data Communications happy. The biggest news is the present government's recent announcement to invite proposals from the private sector to establish and operate Data Networks in Pakistan. Numerous organisations bid for the services, and it is now reported that all of the applicants would be allowed to move ahead with the project, and prove by deeds what they had put down in words; of course, after fulfilling certain Government conditions. I believe this is a healthy development since it allows the market forces to select the able and the competent and weed out the amateurs.

Again on the Public Data Network Scene, it is a good news that the PTC Network, based on Packet Switched Network Technology has now started offering PDN access through Public telephone (dial up) Network. Therefore, allowing medium to small Data Communication users to access multiple National & International Data bases at reasonable connection cost by dialling a local city number. This facilitates transfer of Data at relatively higher speeds with greater reliability. Also for high volume users of the Network, PDN would be able to offer 64Kbps data communications through leased lines soon.

The benefits of research in USA in the field of defense related technology are also now available in Pakistan. I refer here to the spread spectrum way of radio transmission which was developed for the US defence establishment as an effective way to over-come jamming. Now Radio Moderns based on this technology are available. These Radio Modems allow high speed (64-512Kbps) transfer of data over line-of-sight links. The use of Spread Spectrum Technology due to its very high degree of tolerance for interference and noise maximise the use of Radio Spectrum, an attribute that prompted the FCC to issue its landmark Part 15 regulation in 1985. …
