<< Why pay good money for slightly faster >> Message 15918859 orange.co.uk What's the application? With HSCSD, fast access to the Internet will become the norm. Other technologies, such as General Packet Radio Services (GPRS), will complement and enhance the value of HSCSD. There are applications for both circuit-switched and packet-switched world. For instance, if the user needs to make PSTN/ISDN connection (towards corporate modem pools), only HSCSD can be used. HSCSD is ideal for real-time applications and GPRS for "always connected" applications. For example, HSCSD connections provide "active" e-mail and file transfer, while GPRS will run in the background for wireless data networking. << case that can be made for HSCSD >> Take a product like the 9210 - which has no equivalent for functionality for the corporate user. Add a very low cost upgrade to an existing network - lock in the high APRU corporate client with access to their intranet. I suspect you might be able to build a business case, Available NOW, not 6 months from now, 9 months from now, on 32 networks with 90 million subs. Why does AWS and Nextel boast higher APRUs than Sprint PCS or Verizon? - Eric -

re: HSCSD/GPRS << Last time I checked .. Why pay good money for slightly faster (14.4 max vs. 9.6 max) data transfer that is deficient and buggy? Check again ... also think data compression and optimization ... and remeber the application and the customer target. >> Eircell Answers HSCSD/GPRS Questions eircell.ie In an industry famous for acronyms, there are two in particular that Eircell customers will become very familiar with over the coming months - HSCSD (High Speed Circuit Switched Data) and GPRS (General Packet Radio Service). This article will explain how these technologies work and what they mean for the future of Eircell mobile communications. HSCSD Eircell is one of the first mobile networks in Western Europe to bring High Speed Circuit Switched Data to the market. Other operators across Europe have subsequently announced plans to introduce HSCSD services and with good reason. HSCSD has effectively smashed the glass ceiling imposed by the architects of GSM. When GSM was designed in 1988, fixed line data rates had peaked at the Group 3 fax standard of 9,600 bps (bits per second). Conventional modems were still operating at 2,400 bps so it was reasonable to expect them to reach parity. Unfortunately, in the time taken from the GSM standards ratification to the launch of public service, fixed line data speeds had jumped to 14.4 Kbps (14,400 bps) and continued to increase, reaching 56.6 Kbps by 1998. GSM, using a complicated combination of digital radio channels and time-slots had been optimised for 9,600 bps transmission and it was not possible to squeeze any more data across the link. An urgent solution was required - the future of mCommerce depended on it and with mobile data accounting for more Eirtime than ever before, something had to be done. It could be achieved by starting again with a completely new standard or by developing a complementary method that could be added to an existing GSM service. New standards take time to implement, so Eircell chose to give its customers an early lead by installing HSCSD. Eircell is the only Irish network to make such a service available. The solution was to allow the user to access not just a single time slot, but multiples of two or three. Each ‘slot’ in isolation is subject to the standard data rate of 9,600 bps, but when combined the available bandwidth is increased - allowing for faster data transmission and shorter download times. Under ideal conditions, download speeds up to 43.2 Kbps are possible, over three times faster than conventional GSM. Phone manufacturer Nokia has led the development of HSCSD Phones and Card Phones - notably the Nokia 6210 and Nokia Card Phone 2.0. This latter option slots into a standard laptop, is equipped with a SIM card and therefore doesn’t require a mobile phone. Whilst some observers described HSCSD as a short-term option until the introduction of GPRS, this is incorrect. Should a user need to connect to a corporate LAN (Local Area Network) or any data provider with a PSTN/ISDN connection, HSCSD is the only option. It also allows for authentication, dial-back security and from a pre-approved list of mobile or fixed callers, only those with the relevant permissions can access the network. For applications such as e-mail, LAN access and file transfer, the real time nature as well as the high data rates make Eircell High Speed Data hard to beat. So what makes GPRS different from the HSCSD offering? GPRS GPRS is currently under trial in Dublin and Eircell has plans to roll out the service nationally later this year with the precise launch date depending on the availability of new phones supporting this new standard. Analysts are predicting that GPRS will herald the development of ‘consumer data’ WAP services as packet data is ideally suited to the transfer of WAP information. Because data will be delivered in a steady stream to the phone - which will be operating in an ‘always on’ mode - users will have the information they require delivered to their phones, rather than having to make a specific call to receive the data. For corporate users, providing you have a permanent Internet connection to your server, e-mail can be quickly retrieved by employees on their mobile phones as well as from their desktop. It will be the ability of responding to these e-mails or connecting to the company WAN/LAN (permitting access to databases and contacts) as well as the synchronisation of work schedules and meetings that will finally allow full office functionality from a mobile phone. GPRS also has the potential to touch new vertical markets - for example, the evolution of our Laser debit cards will increase as packet radio based terminals will allow consumers to pay for products or services away from fixed communications links. Remote metering, security and equipment control can be managed centrally, with costs based only on the amount of data transferred. In summary, the benefits of the technology include high data rates and fast connection. WAP services will dramatically benefit from faster response times and the ‘always on’ architecture. Eircell’s decision to offer both data delivery methods gives users unprecedented choice and allows the company to select the most appropriate technology for its needs. And Eircell is already looking towards the next wave of mobile communications, which will come in the form of third generation technology or UMTS (Universal Mobile Telecommunications System). The competition for the Irish UMTS licences will take place next year. These licences will allow operators to deliver high bandwidth services such as video over mobile as the capacity on mobile networks increases significantly. Obtaining UMTS spectrum will also increase the amount of capacity available to mobile network operators, which is crucial since mobile phone usage in Ireland continues to rise rapidly. It is clear over the next 12 to 18 months and beyond, all these technologies will have a massive impact on the way people communicate while on the move. With mobile data traffic expected to overtake voice, Eircell is well placed to make the most of the mobile data revolution. The Technology Explained * Bps - Bits per second Bps is the amount of data that can be sent over a connection. The higher the number, the faster data can pass over the connection, resulting in shorter call times. Kb/s = bps x 1,000, so 9,600 bps and 9.6 Kb/s mean the same. A typical PC modem will operate at 33.3 or 56.6 Kb/s (33,300/56,600bps). * GPRS - General packet radio service GPRS is a packet switched network which supports the IP (Internet Protocol) standard, allowing end to end IP connectivity from GPRS mobiles to fixed networks. GPRS users can be continuously attached to the network, allowing mobile users to simply be an extension of the corporate LAN/WAN. * HSCSD - High speed circuit switched data Eircell High Speed Data is based on the HSCSD platform, which currently delivers speeds up to 28.8 Kbps without data compression - 3 times faster than previous GSM technology allowed. Early next year speeds will increase to 43.2 Kbps without compression - 4.5 times faster than standard GSM. Eircell High Speed Data can be accessed via a Nokia Card Phone 2.0, ideal for situations where you need to be on the phone and sending information at the same time, or a High Speed capable phone.

Carranza, are you as intellectually honest in your own thoughts as on this thread?? Ilmarinen Btw, Sonera bills HSCSD with an exponantially decreasing cost per added time slots, not that it really matters for the majority of those using a communicator. Btw,btw, have you ever been involved in really important business, even needing to do some traveling away from home, whining about communication costs?? Maybe even needing a sloppy satellite phone dropping or some added security?? Or do you just worry about your next moving color picture when luckily away from home??

re: Orange or CONNEX HSCSD & HSCSD Odds & Ends orange.be orange.be >> Make Your Office 3 Times As Mobile With High Speed Data (HSCSD), Orange is offering an unequalled data transmission speed of 28.8 Kb/second. The user has a dedicated circuit(s) asigned to make a data call with High Speed Data All you need to do is plug a Nokia Phone Card into the PCMCIA port of your laptop. This will give you wireless access to the Web or your company network. Wherever you are, you can fax, e-mail, surf and download at high speed, even when you are working with large files or video material. The transmission speed offers you a lot of advantages: HSCSD is the first step to a real mobile office, where you acess text-and information services, Internet, static and moving images, e-mail, multimedia in a very friendly way. With HSCSDD receiving and sending of E-mail is much faster, just like downloading Internet pages. You pay less communication costs, because the information you asked for is transmitted much faster. High Speed Data kits What do you need for HSCSD? A notebook, laptop or PDA with a Type II PCMCIA port. The Nokia Card Phone 2.0. Other handsets will become available. In Overdrive with Business Talk Orange advises you to choose Business Talk if you work with HSCSD. You will benefit from the same rates, day and night. The costs of calls to fixed lines are highly advantageous and the international rates are attractive too. Furthermore, you will benefit from all-in protection free-of-charge in cases of the theft of, loss of or damage to your Nokia Card Phone. The Orange HSCSD kits can be bought from any of the Orange points of sale as well as from IT materials retailers. << Or try CONNEX connex.ro >> Applications: Applications suitable for HSCSD are real time applications where quality of service is important and high data volume transfers. Some applications such as fax and video requires transparent service, while other such Internet, e-mail work well with non-transparent services. We propose the following applications to be taken into consideration, for future development of HSCSD services: Internet Access The possibility to access the Internet regardless the place, simply by using your mobile (HSCSD terminal and a laptop). * Company LAN Access (Intranet Access) - To have permanent access to all the resources that are on your company LAN * Mobile e-mail and Fax _ The possibility to scan your own inbox and download e-mails, to send and receive e-mails while on the move. * Telemetry - Traffic surveillance, Remote control of industrial equipment, Security applications << Odds & Ends >> HSCSD High Speed Circuit Switched Data answers the problem with current wireless data communications: bitrate. Current applications, such as email and remote LAN access, as well as new applications, such as wireless imaging and video, will benefit from higher bitrates. HSCSD provides data throughput 6 times faster than that of current GSM data with only minor additional investment. This technology (which ETSI approved and specified in February 1997) employs a new channel-coding scheme that increases the time-slot bitrate from the current 9.6 kbit/s to 14.4 kbit/s. HSCSD also enables the combining of time-slots so that data rates in multiples of 9.6 kbit/s or 14.4 kbit/s are possible. This means that operators will be able to provide GSM users with a variety of new bitrates, ranging from 9.6 kbit/s to 57.6 kbit/s. An HSCSD bitrate of 57.6 kbit/s, uncompressed, is comparable to one ISDN B-channel, putting GSM data on a par with existing PSTN modem services. With end-to-end compression, for example between laptop software clients and a network server, rates of up to 200 kbit/s could be achieved. During off-peak hours, when other traffic is lower, the network could easily offer more time slots for the data service, so increasing the overall usage of off-peak idle capacity. HSCSD, being mainly a software upgrade (probably done with remote access), does not entail new network elements and so the GSM operator not only avoids having to redesign the network, but can also have fast implementation. However, the user does require a new terminal. HSCSD does not require the user to ‘learn’ an entirely new data service or technology: it is very similar to existing services, just substantially faster. Applications such as mobile navigation services and other features using maps and graphics will benefit greatly from the enhancements provided by this technology, making applications more attractive and easier to use. However, HSCSD will enable completely new applications too, such as mobile video. HSCSD will initially be used mainly with laptops. The business segment is thus the most logical segment to serve with more sophisticated data services for wireless office applications and access. HSCSD will be commercially available before General Packet Radio Service. To summarise, the benefits of HSCSD include: * Early adoption of HSCSD give competitive advantage by attracting the business subscriber segment of the market * High-speed services can be launched without major investment in infrastructure (only a remote software upgrade is needed), resulting in fast payback * During off-peak hours the network can provide substantially higher bitrates with 3 to 4 time-slots according to traffic needs, increasing overall off-peak idle capacity usage. << - Eric -
