sales field training Host Connectivity IBM 3270 Hosts IBM ES9000 IBM S390 IBM AS/400 Bull / Honeywell Tandem

sales field training Host Connectivity IBM 5250 Host IBM AS/400

sales field training Host Connectivity Thick Client: –Terminal emulation software resides on the hand held which communicates directly to the host –TNVT100/220, TN3270, TN5250 TN = Telnet –TCP/IP over Ethernet to Host Required –No Universal Gateway required –aka “Direct Connect”

sales field training Host Connectivity Typical thick client configuration

sales field training Host Connectivity Remote thick client configuration

sales field training Host Connectivity Thin Client: –Some terminal emulation software resides on the hand held, the rest resides in the Universal Gateway –TNVT100/220, TN3270, TN5250 TN = Telnet TCP/IP over Ethernet –aka “Server-based connection”

sales field training Host Connectivity Typical thin client configuration: TN

sales field training Host Connectivity SNA / SDLC supported Special quote! Lead time longer with this setup! Additional info available upon request

sales field training Host Connectivity Thick versus Thin Client Pros & Cons Rules of thumb

sales field training Host Connectivity Thick Client –All terminal emulation software is located on the RF terminal. The RF terminal communicates directly to the terminal emulation host Thin Client –A smaller amount of software (thin) resides on the RF terminal and the RF terminal communicates to the Universal Gateway. The Universal Gateway then communicates to the terminal emulation host.

sales field training Host Connectivity Thick client pros –Less system cost –Less hardware Thick client cons –Difficult to trouble- shoot remotely –More work to maintain –No data optimization

sales field training Host Connectivity Thin client pros –Remote dial in for easier trouble shooting & remote support –Easier to maintain –Optimizes data over network Thin client cons –More cost –Extra piece of hardware

sales field training Host Connectivity Thick client rule of thumb: –Less than 15 – 20 terminals single site –Less than 15 – 20 terminals multi site in close proximity Thin client rule of thumb: –Greater than 20 terminals single site –Greater than 20 terminals multi site –Stressed wide area network involved

sales field training Host Connectivity RF Simplicity –Tool for rapid application development –RF Simplicity takes care of TCP/IP sockets connection –Runs in Visual Basic environment under Windows 95/98/NT, perfect for VB programmers –Best solution for Windows host environments HANDS DOWN! –RF Simplicity could be used to off load processing from typical TE hosts

sales field training Wireless Technologies Frequency Hopping (FH) –WLIF –aka “OpenAir” Standard Direct Sequence (DS) –802.11b (DS) –IEEE Standard Vendors

sales field training Wireless Technologies Frequency hopping spread spectrum. –Transmits on a single frequency for specified period of time, then hops to another frequency for a period of time etc.

sales field training Wireless Technologies Frequency hopping spread spectrum. –Interference avoidance by hopping. –Interfered transmission is resent.

sales field training Wireless Technologies Direct Sequence Spread Spectrum Data is split up and redundantly transmitted simultaneously over a large bandwidth

sales field training Wireless Technologies Direct Sequence Spread Spectrum – MHz wide stationary channels –11, 5.5, 2 and 1 Mbps data rates possible –3 non-overlapping 22 MHz channels –Potential 33Mbps with 3 Access Points

sales field training 2.4 GHz Solutions WLIF –Proxim based solution “OpenAir Standard” –Frequency Hopper –HHP supported –Will not work with Frequency Hopper!

sales field training 2.4 GHz Solutions b –Direct Sequence Spread Spectrum –HHP supported with Aironet/Cisco, –Aironet/Cisco radio interoperable with existing b competitor installations
