Wireless Technology and IASL Meshed Back Backbone:IASL is one of the few providers to ensure that all client base station sites are connected to the core network with multiple paths. Providing multi-paths to the core network allows IASL to provide the client with a reliable service, and ensures the client that there is no single point of failure in the backbone network. By using a Mesh or Ring topology the network will automatically re-route traffic via another available link should any link fail. IASL also pro-actively monitors and maintains all links to ensure clients that a required fade margin of not less then 15db is achieved. Radio Sensitivity: Both IASL Core and Customer Premise Radios have a high sensitivity level of -85dbm (this is the level that the radio can hear incoming signal). IASL engineers its radio links to have minimum signal level of -70dbm leaving a 15dbm minimum fade margin. Typical links have a level of -60 to -65 dbm leaving over 20dbm of fade margin. The end result of this engineering is found in the links high availability and reliability for the client. Short distance between Tower and Client: Unlike many other wireless Internet providers, IASL keeps the links between their client and the tower sites short. The amount of signal that the radio hears is directly related to the distance between the base station and the CPE. Thus, by keeping the distance to less than 4km from the main tower sites, IASL ensures a high quality link to the end subscriber. Line of Site: Microwave radio technology requires clear line-of- site. IASL ensures that all client links have clean un-obstructed line-of-site to one of the many Multi-point towers. There is no exception to this rule. Weather conditions can affect certain wireless communication Systems. IASL however utilizes frequency bands that are not affected by weather. Frequency Band, Distance, and Radio sensitivity are the three main concerns when dealing with environmental conditions. IASL uses frequencies in the License Example Local Area Network (LE-LAN) band to connect subscribers to the core of the network. The frequency ranges utilized by the LE-LAN networks are not affected by rain / snow Contact your IASL representative today.
