The more mobile your employees, the more you should consider a wireless network. The portable transaction computers (PTCs) make it possible for direct connection between the office and offsite locations.
The iSeries™ wireless network is a LAN that uses a Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) protocol to provide media access to competing stations. iSeries wireless communications use spread-spectrum, direct sequence radio in the 2.4 gigahertz (GHz) band to provide connectivity between the iSeries wireless LAN adapter and remote stations. Remote stations can be PTCs that are running 5250 emulation or LAN-connected systems that are equipped with compatible wireless adapters. There are other implementations of wireless LAN.
