BOX C, MARKET HARMONIZATIONOn Tuesday, April 11, 2000, Ericsson, Motorolaand Nokia announced that they have teamedup to create a common framework for mobilee-commerce. The main objective of this jointindustry effort is to ensure complete marketharmonization in terms of how certificates,keys, processes and services are implementedin mobile phones and offered to end-users.The framework for how mobile transactions areto be handled and implemented will be draftedand distributed for comment from relatedplayers in the industry (operators, serviceproviders, bankers, credit card companies,retailers, and so on). The framework will bebased on the wireless application protocol(WAP), WIM/WTLS, WPKI and Bluetooth.the phone as a payment device. Support isoffered for several major credit cards, includingVISA, MasterCard, American Expressand Diners Club.Mobile e-Pay prepaidaccountA dedicated e-commerce prepaid accountcan be connected to the mobile e-commerceservice. The prepaid account, which is administeredand issued by the Mobile e-Payoperator, can be used to pay contentproviders for goods and services. Mobileusers can check account balances from theirphones. The accounts can be filled manuallyby the Mobile e-Pay operator, or users canfill them using credit cards in combinationwith the credit card payment or the bankaccount /debit card payment features.Bank account/debit card paymentThe payment server can implement marketdependentinterfaces to partnering banks ornational banking networks. The implementationof market-specific banking interfacesis a common practice with payment serverdeliveries. Bank or debit card payment is notpart of the standard Mobile e-Pay offering.To the end-user, the procedure is the sameas for credit card payments.Content provider API (software library) forpaymentsAn application program interface and an IPconnection are all that content providersneed to connect to Mobile e-Pay paymentfunctions which are connected to financialinstitutions. To use Jalda payments, a separateJalda API is also needed.ConclusionAlthough the global digital economy is stillin its infancy, it will grow to support a hugeand complex market. Service providers whohave the tools that help consumers experiencethis new market as easy-to-understand,user-friendly and convenient will be handsdownwinners. In fact, we might define thetrue value of mobile e-commerce as the abilityto make specially tailored services directlyavailable to the consumer via a familiar,portable device.For mobile operators and content and serviceproviders, mobile e-commerce representsa new way of adding value and of differentiatingthe services they offer, as wellas of expanding their markets and buildingcustomer loyalty. It is quite simply an entirelynew sales and promotion channel. Unlikebrick-and-mortar retail outlets, mobilee-commerce can be thoroughly tailored to aconsumer's individual needs and tastes. Andit is available to that consumer anywhere,anytime. In short, mobile e-commerce is allabout consumer empowerment.The right combination of mobile systems,Internet, payment, and security technologiesnow exists to make mobile e-commercea commercial reality. Ericsson's Mobile e-Pay solutions enable operators and serviceproviders to generate new classes of servicebased on each user's geographical locationand personal profile. As the world wakes upto the huge potential of mobile e-commerce,mobile operators and service providers willhave the unique opportunity to establish alead in the market.92 Ericsson Review No. 2, 2000
The RBS 2206—A flexible ticket to third-generationwireless systemsPer WilenThe migration from second-generation to third-generation mobile systemsis one of the core issues facing the industry as it enters into the new telecomsworld. Ericsson is committed to making this migration as seamlessas possible for the operator. One of Ericsson's cornerstone products is anew, indoor macro-base station—the RBS 2206.Twice the capacity, samefootprintThe RBS 2206 is a successor to theRBS 2202, which is the world's most deployedGSM base station. A new doubletransceiver unit (dTRU) in the RBS 2206gives it unsurpassed capacity: with room forsix dTRUs, it can serve as a 12-transceiverbase station, which is twice the capacity ofthe RBS 2202. Nonetheless, the footprintof the two models is exactly the same, whichis an important point—today, many basestation sites host two RBS 2202 units. Ifthese units were replaced with the RBS2206, the extra space gained at the site couldbe used for a second unit, say, one that supportsthird-generation standatds (Figure 2).Thus, operators can build a third-generationnetwork using existing sites. This is goodnews, since site space is a valuable operatorasset.True bridge from 2G to 3GWhen an operator decides to implementthird-generation technology, the RBS 2206can provide coverage quickly. Indeed, theRBS 2206 is a true bridge from second- tothird-generation systems. Full support forenhanced data rates for global evolution(EDGE) is achieved by adding one or moreplug-in transceiver units in the cabinet'stransceiver slots; support for widebandcode-division multiple access (WCDMA) isachieved by adding a plug-in WCDMAtransceiver unit (WTRU) and a remote radiounit (RRU). The RBS 2206, which representsa flexible, low-cost ticket to thirdgenerationcapabilities, is especially suitedto sites where space is a premium (urbanareas) or where coverage is the main priority(rural areas).Plug-in WTRU and remote radio unitAs mentioned above, the RBS 2206 can beexpanded to support WCDMA using aplug-in WTRU, which contains basebandfunctionality (Figure 3). A remote radiounit, which can be placed anywhere betweenthe cabinet and the antenna, contains radiofunctionality and power amplification. Theconnection between the base station and theremote unit is made by means ofa fiber opticcable, making installation flexible and easy.Up to three RRUs can be deployed, dependingon the number of sector configurations(one, two or three).Figure 1Photograph of the RBS 2206.
