4 SMS is a point-to-point store and forward technology with 2 basic services: Short Message Mobile Terminated (SM-MT) Short Message Mobile Originated (SM-MO) SMS allows message delivery to handsets either active/in-use or powered off SMS-Submit,SMS-Deliver SMS protocol permits request of message delivery confirmation report SMS messages are transported in the core network using SS7 (Signaling System 7)

12 1. User would log on to sms2 account. 2. Once user has logged on/signed up, you would click on "textback". Under this heading you can then reserve your keywords (subject to availability) 3. Once you have your keyword(s), user can start a campaign. Any text message sent to with user keyword at the start of the message will be forwarded to user by and also stored on SMS Gateway service provider database so user can download them at a later date. NOTE : This service is free to all accountholders. However, it is subject to a fair-usage policy. If you are using this service for business purposes, we would recommend contacting us for a dedicated number. Note: (1) Application Web Server of SMS Gateway service provider. (2) Internet (3) SMPP Traffic (4) SMSC (5) GSM Network

13 1. Installing it in a SIM slot in one of GSM modems (1). 2. SMS Gateway Service Provider application servers check user SIM card (2) for content every 3 seconds. Note: SIM based technology, the maximum throughput of messages is one per 3 seconds, up to a limit of 30,000 per month 3. The incoming messages are processed and entered into the secure database (3) and all messages are associated with user sms2 account login. 4. In order to view the incoming messages, you can log in to your sms2 .com account and download them in Microsoft excel compatible csv format, or (at no extra cost) you can have the messages forwarded to you via (4), or HTTP POST'ed (5) to your own application server Note: (1) GSM Modem (2) SMS Gateway Service Provider Application Server (3) Secure database (4) Gateway (5) HTTP/HTTPS Interface

28 Voice:In the form of calls made. SMS: MMS: WAP (wirelessapplication protocol) Pocket data IC & EV-DO cards. Prepaid and Postpaid Services VPN(Virtual Private Network) Bank ATM / Branch ATM connectivity

29 Technique Used CDMA uses code divisionmultiple access whereas GSM uses timedivision multiple access. Power Consumption and Adjacent ChannelInterference Data Transfer Speed- CDMA has beentraditionally faster than GSM, though bothtechnologies continue to rapidly leapfrogalong this path. Both boast "3G" standards, or3rd generation technologies. Subscriber Identity Module (SIM) cards and RUIM
