Introducing iConnectorLEA Low-Cost IP-Enabling
Adapter for 2.5G and 3G Cellular Modems
2
2.5/3G Apps Need Internet Protocols

• Modems usually include IP layer, not TCP/UDP
• You must rewrite application to support TCP/IP
• Internet programming expertise required
• May require major HW and SW redesign
• Issues Time-to-market, cost, development risks
• Must overcome limitations of 2.5/3G network

3
The Do-it-Yourself Approach

• Redesign hardware (if needed)
• Select new processor, add memory (if needed)
• Buy / develop TCP/IP stacks and maybe new OS
• Rewrite application
• Integrate TCP/IP stacks and commands
• Debug, test, debug, test
• Invest many man-months and lots of money
• Financial, technological and marketing risks

4
Wireless Modems with TCP/IP

• Every modem implements TCP/IP stack differently
• Limited implementation of TCP/IP stack on modem
• Generally dont include upper layer protocols
• Lack features to optimize 2.5/3G connection
• Require Internet programming for application
• Dont include a mode for streaming data
• Are not plug-and-play

5
What Do Customers Want?

• Use existing application
• Low-cost, risk-free wireless IP connectivity
• Minimum changes to current product
• Avoid Internet programming
• A choice of Internet protocols
• Easy implementation and maintenance
• Reliable connectivity and excellent support

6
What Does Connect One Offer?

• All of the above in one compact,
• off-the-shelf product !

53 x 33 x 17 mm (2.1 x 1.3 x 0.67 in.)

Why Use Connect One Solutions ?
Plug-and-Pray
The Internet is

• Dynamic constantly in flux
• Complex more than just TCP/IP
• Inconsistent ISPs, servers
• Not your core competency

Which is better Do-it-yourself or off-the-shelf?
8
Connect One Value Proposition

• Eliminate the time, cost and complexity of
  connecting devices to the Internet

• Cost of acquisition cost of ownership

• No hidden costs

• No financial, technological or marketing risk

• An off-the-shelf solution makes more sense than a
  do-it-yourself solution

9
Core Technology iChip

• Internet controller that mediates Internet link

• gt500k units installed since 1999 with 100s of
  ISPs in over 50 countries

• Works with any host device and any (or no) host
  operating system

• High-level API for easy, fast implementation

• Internet protocols and configuration parameters
  are stored in remotely updateable flash memory

11
ATi Protocol

• Logical interface between application and iChip
• Internet extension to AT command set
• Always adding new functionality and features
• ASCII commands invoke Internet protocols on iChip
• Requires just a few commands on host application
• Transparent Mode AT commands bypass iChip
• Internet Mode accesses ISP via host ATi
  commands
• SerialNET Mode requires no change to application

12
SerialNET Mode

• Bridges between ASCII data and TCP/IP packets
• Uses TCP/UDP sockets to connect to remote device
• No need for ATi commands on host device
• Device can act as server or client
• Ring response server for automatic wake-up
• Connectivity watchdog ensures that modem is
  always online

13
iConnectorLE True Plug-and-Play Device Server

• Connects installed devices to Internet via serial
  port
• Works with most cellular modems/handsets and any
  analog modem
• No Internet programming required
• No modification to host application or OS
• No modification to host device hardware
• Works with any wireless operator anywhere

14
iConnectorLE Features

• Includes iChip CO110PC with locally updateable FW
• Basic FW includes 10 simultaneous TCP/UDP
  sockets, two listening sockets, Web client, and
  RAS server
• Optional FW versions Basic FW plus SerialNET
  mode or SMTP/FTP client mode
• DTE-DCE (female-male) configuration
• Takes power from pin 9 of host device DB-9
  connector
• Extended temperature range operation
• Supports 2400 through 230k bps baud rates

15
Value-Added Features for 2.5/3G

• Optimized to improve cellular networks low
  reliability.
• Always Online mode automatically reconnects if
  modem disconnects, or if signal or connection is
  lost.
• IP Registration via sockets, email or Web enables
  accessing devices with dynamic IP addresses.
• Packet filtering reduces unneeded transmissions,
  costs.
• Send AT commands during Internet session.
• Device Connectivity Server enables accessing
  devices within a cellular network from outside
  the network.
