Wireless hotspots have gained a lot of attention, particularly as the number of hotspots has increased dramatically, and WLAN technology has become prevalent. The debates of whether hotspots are complementary or competitive with 3G cellular go on, as does the nature of an effective business model, but nobody can deny that hotspots are becoming an important part of the networking landscape.

This goal of this meeting is to examine the latest technical developments affecting hotspots, including standards, interoperability and interaction with cellular data networks. This will include an overview of smart client connectivity methods, wireless security considerations including the use of VPNs and the application of IEEE 802.1X to public networks and cellular based authentication methods such as SIM.


Recent developments in this area include:

  • Voice over WLAN. (e.g., Toshiba just announced new Pocket PC devices with support for VoIP over WLAN)
  • The Oct 20 release by the WLAN Smart Card Consortium of the WLAN-SIM 1.0 specification.
  • Microsoft's announcement on Oct 12 of it's Wireless Provisioning Services to facilitate hotspot access using Windows XP.
  • Efforts by 3GPP and the GSM Association WLAN Task Force in this area.
  • Improved software clients that integrate hotspot location directories and automated logon.
  • The promise of using EAP-SIM (also PEAP-SIM, AKA-SIM), with 802.1X and RADIUS for a standards-based approach that offers comprehensive security, roaming, integration with cellular networks and an instant-on user experience.
  • Multiple SIM options including USB devices, smart cards, Bluetooth/IR connections to cell phones and virtual SIMs.
  • Recent projections by Pyramid Research of 45,000 hotspots globally by the end of this year.

At this meeting, we also plan to analyze something we are calling service continuity, which refers to how wireless devices should behave when network coverage is marginal, or in the presence of multiple networks. For example, should a multi-mode device always try to acquire a WLAN connection when both a WLAN and cellular data connection are available? Under what conditions should it move from one WLAN network to a different one? It could get expensive at an airport to automatically purchase multiple 24 hour blocks of service from different operators. For a cellular data connection, if coverage is weak from one operator, should the device connect to another operator? The PCCA is considering the development of profiles that define exactly how devices operate in these conditions. Vendors could then design to these profiles, and applications could specify which profiles to use.




Meeting time: 8:30 AM to 4:30 PM. The preliminary agenda is as follows.

If you are interested in attending this meeting, please register by sending e-mail to:


Please include your name, company name, e-mail address and phone number and indicate whether you are attending the workshop, meeting or both.

Meetings are intended primarily for PCCA members. However, non-member organizations that have not attended a prior PCCA meeting, interested in the topic and wishing to learn about the PCCA, may attend on an introductory basis for a fee of $375 per person. This fee can be applied towards membership. For others, please contact us for alternative arrangements.


The following information is for people presenting at this PCCA meeting: 

  • Presentations are typically 30 minutes to 45 minutes long unless arranged otherwise.
  • This is a technical audience, so please make the presentations technical. Emphasis

  • should be on industry issues and proposed solutions versus selling your product. 
  • There is usually a 5 to 15 minute discussion following the presentation.
  • We will provide an LCD projector.
  • The audience is technical, consisting mostly of engineering and program managers.
  • Generally, 30 to 50 people attend each meeting, representing a broad spectrum of

  • the wireless industry, including carriers, infrastructure vendors, device vendors, 
    software vendors and computer vendors. 
  • If you are presenting a technical contribution, please provide hard copy for attendees. We will advise you on the number. 
  • We request a copy of your presentation (PDF or PPT) before the meeting so that we
  • can post it in the members area of the PCCA web page.
