Recommendation (continued)

The fiber optic cable laid along railway tractshould be further utilized

BTRC should be allowed to work withoutgovernment influence and control

BTTB should be privatize

Proper cabling should be done to avoid

bandwidth limitationIT (Electronic Signature) Acts shouldimmediately be implemented

Conclusion

The present government has recognized ITas thrust sector

A large number of bright students andentrepreneurs have shown interest in IT

Strong data network within the country andbetween the country and outside world are
