SIM with WiFI





Sagem Orga and Telefonica have been working on next generation SIM card called SIMFi.

With SIMFi, you can convert a phone into a WiFi hotspot. The phone would use HSPA/LTE for data connectivity and at the same time it would broadcast WiFi signal for any equipment to connect to these signals ans browse the web. Power consumption information have not been mentioned which I am sure be a problem for the phone.

SIMfi removes the need for additional accessories to facilitate transmission services (e.g. WiFi, USB modem, PCMCIA) and can make connectivity a lot simpler, straitforward and cheaper.


SIMFi specifications
  • SIM card compatible with the latest telecom specifications.
  • SIM card: ISO 2FF plug-in
  • The mobile phone does not need any special features.
  • Modem WiFi integrated in the SIM card, works with 802.11b.
  • The modem is guided by the SIM card's tools.
  • Energy-saving features (works with 2G and 3G).
  • The aerial is adaptable, allowing short- and long-range operations (from 2 cm to 30 m) managed by the SIM card's tools.

Bluetootch 3.0 has a big problem on consuming too much power. The new 4.0 specifications allow for smaller devices that require coin-cell batteries to run.

As well as utillising less power, the device also has higher speed data transfer. Version 3.0 was launched last year although it kind of fell flat on it's face due to the power requirement needed. Version 4.0 fixes those problems

Versio 4.0 allows devices to jump onto Wi-Fi 802.11 networks, where it can transfer data at up to 25Mbits per second.

Hopefully with the lower power requirement s and the options to switch to 802.11 netwroks we should start seeing more devices using the Bluetooth sepecifcation.

Discovery Protocols for FMC devices


Mobile computers include additional features such as Java, Bluetooth, Smart Covers, WAP 2.0, and JavaScript enabled Web pages and with embedded SOAP, 3GPP with SIP, and other technologies that make it possible to provide sophisticated, distributed applications. These new application need Discovery tools to learn about the nearby networks or network-accessible resources available to them.

In FMC, PnP devices (Plug and Play) will be commonly available. When a user bring a new device home, the device will be able to automatically integrate itself into the home network. Discovery protocols are the mechanisms that make this possible.

Discovery protocols are network protocols used to discover services, devices, or other networked resources. The ability to discover networked resources at runtime makes it possible to dynamically configure distributed systems.

The main topics for discovery protocols are scalability, security, and awareness.

Usually, a discovery protocol allows a service to be discovered on the basis of its type, its Application Programming Interfaces (APIs), and other properties -- not joust its name. For example , DNS is a name service. It resolves domain names to Internet Protocol (IP) addresses. For example SLP(Service Location Protocol) clients can ask for services that match certain constraints, and servers respond with the names of services that match those constraints.

In general, there are four basic mechanisms that discovery protocols use for "discovery"
1. Advertisement
2. Inquiry
3. Directories
4. Description

Today's systems implement multiple discovery protocols. However, Mobile phones users may be concerned inefficient protocols designed for LANs -- both the financial cost of using the cellular network and the drain on their batteries of using any network.

It is common for discovery protocols to come as an integrated part of a distributed middleware toolkit. In addition to discovery, distributed middleware toolkits provide for remote invocation and events. Jini is a distributed middleware toolkit that provides its own services discovery protocol.

Distributed middleware toolkits make it possible to create smart controllers that
1. use discovery protocols to integrate themselves with the home devices.
2. aware the device state and display information from the device to the user
3. receive responses from control messages
4. authenticate themselves as authorized for the device
5. coordinate the actions of many devices.

FMC + M-to-M

Improved availability, reachability, and cost saving enabled by FMC can be applied not only to communication between humans or humans and machines, but also to communication between machines themselves, for instance, intelligent devices with microprocessors running application-machine-to-machine(M-to-M)-with far-reaching consequences.


As shown in the first figure, we could allow persons and remote applications to monitor the status of stationary and semistationary objects in the home zone and control their behavior based on policies, changing conditions, and other factors. The home-zone objectes may interface with the home-zone M-to-M controller via low-power, close-proximity tehcnologies such as ZigBee, defined in IEEE 802.15.4 specifying wireless personal area network, and z-ware, or more manstream Bluetooch and Wi-Fi techonologies.



The applications relying on such a sybiosis of M-to-M and FMC may include inexpensive and easy-to-install, 8 standards-based, remote monitoring and control equipment. In residential applicaiton, for example, communicating thermostats, security systems, and lighting, as well as numerous mobile assets belonging to a household such as vehicles, pets, and family members, can be enabled to maintain uniform connectivity and create an M-to-M ecosystem, as depicted in Figure above.

FMC:Fixed Mobile Convergence




FMC will enable single device to perform myriad functions. The main points of interest are:

Dynmaic increase of IP based services especially driven by fixed access
VoIP replaces circuit swithched service in fixed networks
VoIP will replace circuit switched voice in mobile networks
The border between fixed and mobile networks dissappers

Whis is ubiquitous?

I the answer from nikken news paper.

生活空間の中にあるもののすべてにコンピューターチップなどを組み込み、それぞれがお互いにネットワークを介して通信する未来のコンピューター技術。ラテン語で「どこでも存在する」を意味する「ユビキタス」から、名付けられた。1990年代初めに米国の研究所が開発を始めて広まった。

チップを組み込んだ製品同士などが情報をやり取りするために①病院で入院者の様子を見守る②自動車が最適な道のりを得る③冷蔵庫内で食材を管理して自動的に献立をつくる④地震などの発生時に、住民の安否を確認する。

Softbank's free Femtocell

Softbank give the free ADSL connection by using Femtocell. The customers will have to sign a 2 years contract though. With free ADSL connection and a Femtocell, surely the end users are winners. They only have to invest in electricity which would not be a lot. The operator can end up as a winner as well as they get a better coverage by deploying open access Femtocells.
