Abstract: With the growth in the Natural Gas Industry, the need for ever increasing information from the eld is going to force us, as an industry to re-evaluate how we communicate with equipment at remote sites. For the next hour, we will look at some of the options available and discuss the advantages and disadvantages of them. Communications links can be broken down into two general categories: LEASED FACILITIES and OWNED FACILITIES. Most systems that need to cover a large geographic area may require a combination of the two to achieve the optimum communications efficiency. LEASED FACILITIES Leased facilities are those where the communications infrastructure is owned by a third party, and the user contracts for those services. The most common of these are services leased from a local Telephone Company (aka TELCO). The services they can provide vary with company and service area. Well discuss some of their options later in this paper. Another popular option today is cellular data, where the data infrastructure is provided by a cellular phone provider. Satellite communications is another leased option, especially in extremely remote sites.
