Benefits of Wimax WiMAX will enable competition at Broadband market and therefore
reduce associated costs to the consumer.
Convergent (mobility to fixed broadband services)
Social and economic benefits of broadband.
Lack of wireline structure needed to meet the growing demand for
infrastructure.
WiMAX can be economical, easy, faster high performance solution.
Growing demand for broadband and mobility
Symmetric Data Rates
Can be used for different applications (security, health etc)

Through SMS(Short Message Service)
E-Charge-My-Phone Using SMS method allows users to anonymously and securely pay for the products and services purchased via mobile phone
• by sending a text message to a premium number.
Customers are charged on their mobile phone invoice
SMS payment method is designed to work in batch processing mode
• Hence, might take a long time to complete the transaction

New Business Opportunities
Through GPRS(Generalised Packet Radio Service)
(GPRS) is a step between GSM and 3G cellular networks
GPRS offers faster data transmission via a GSM network
• within a range 9.6Kbits to 115Kbits.
Possible to make calls and transmit data at the same time
Before GPRS, for data transmission the entire channel was
occupied and was thus inefficient
GPRS telephones use several channels for data transfer thus
facilitating greater transfer speeds
• More than one user sharing the same channel efficiently
GPRS (2.5G) Overview

BARKOD vs RFID
BARKOD
Needs human to read
It is read only
Must be visible
One etiket can be read at a
time
Easy to immitate
Susseptible to wearing due to
environmentasl effects
Read from short distance
RFID
No need to human to read
Could be read or written into
Must not be visible
Many etikets could be read at a
time (~300 etikets/sec)
Very difficult to immitate
Not susseptible to wearing due to
environmental effects. Age 10 yrs
Reading distance is up to 8m
