Antes sólo teníamos que cargar el móvil cada tres o cuatro días. Ahora nos conformamos si llegamos a la hora de la cena sin tener que hacerlo. ¿Qué ha sucedido en este tiempo? El consumo de energía de los teléfonos móviles se ha multiplicado por tres o por cuatro en dos años. En cambio, la densidad de energía de las baterías que alimentan los dispositivos móviles sólo ha aumentado a un ritmo medio del 5% anual. Esta discrepancia entre demanda y disponibilidad produce una pérdida de autonomía que, según los expertos, no se va a resolver a corto plazo.

En una catástrofe como la ocurrida hace unos días en Haití, los daños en las infraestructuras de telecomunicaciones complican todavía más las actividades de salvamento. El despliegue de redes de telefonía móvil ha aliviado parcialmente el problema en los últimos años, pero sigue siendo preciso alimentar las estaciones base y recargar los terminales que utilizan los servicios de emergencia, algo no siempre sencillo cuando también se ha visto afectada la red de electricidad. Ya existen estaciones base de telefonía móvil provistas de captadores solares o molinos que generan energía eólica, y es de suponer que parte de la ayuda internacional a Haití incluya el despliegue de este tipo de equipos, aunque no tenemos confirmación de ello. En cambio, sí sabemos que la firma holandesa Intivation ha facilitado a la coordinadora de organizaciones humanitarias de aquel país 1.000 de los teléfonos móviles con cargador solar que presentó hace un año en el Mobile World Congress de Barcelona, y de los que asegura llevar vendidos más de medio millón de unidades. Estos móviles solares se distribuirán a través de Digicel, la mayor operadora móvil del Caribe.
Con esta dotación de terminales se suplementará la recarga de móviles mediante baterías de coche que reseña José Luis Orihuela en eCuaderno.
Yesterday Intivation has, in cooperation with one of its shareholders DOEN Participations and client Digicel, donated one thousand solar powered mobile phones to the Dutch Cooperating Aid Organisations and Haiti’s largest micro-finance institution in Port au Prince.
Good communication is an absolute necessity in disaster relief but Haiti currently has a tremendous power problem, which impedes charging mobile phones. The mobile network itself still functions in many instances due to backup generators, or it can be repaired much quicker than the electricity grid.
Intivation is a Dutch company that has invented a technology to enable mobile phones that can be charged exclusively on solar power. Mobile phones that use this technology have been deployed worldwide since 2009, predominantly in regions that do not have reliable electricity girds. Over half a million of these devices have been sold worldwide in the last six months.
DOEN Foundation, financed by the Dutch Postcode Lottery, joins the effort at the urging of Intivation shareholder DOEN Participations; normally the foundation does not focus on disaster relief. DOEN foundation has been a longstanding investor in Haiti, among its participations is Sèvis Finansye Fonkoze (SFF), the country’s largest micro finance institution. This organisation helps mostly women in Haiti with small loans so they can start businesses, and it has 37 branches that can be called on for the distribution of the solar phones.
Digicel is the largest mobile network operator in the Caribbean. Digicel has lost employees and their family members in the current disaster. The company has begun an extensive aid program, in which two private planes are being used for the relief effort to transport goods, and also the solar phones, to the Port au Prince area. Once a landing slot has been granted Digicel will ensure that the solar handsets will be delivered to SFF and Cordaid, which is coordinating the effort on behalf of the Cooperating Dutch Aid Organisations.

Formal Adoption of Specification Enhancement Opens Doors to New Market Creation in Healthcare, Fitness, Security and Home Entertainment
BELLEVUE, WA – December 17, 2009 – The Bluetooth Special Interest Group (SIG) today announced the adoption of Bluetooth® low energy wireless technology, which is the hallmark feature of the Bluetooth Core Specification Version 4.0. As an enhancement to the specification, Bluetooth low energy technology opens entirely new markets for devices requiring low cost and low power wireless connectivity with this evolution in Bluetooth wireless technology that will enable a plethora of new applications – some not even possible or imagined today. Many markets such as healthcare, sports and fitness, security, and home entertainment will be enhanced with the availability of small coin-cell battery powered wireless products and sensors now enabled by Bluetooth wireless technology.
“With today’s announcement the race is on for product designers to be the first to market,” said Michael Foley, Ph.D., executive director, Bluetooth SIG. “Bluetooth low energy modules for all sorts of new products may now be qualified – this is an important step towards our goal of enabling new markets with Bluetooth wireless technology. For example, the Continua Health Alliance has already selected Bluetooth low energy as a transport for the next version of its guidelines.”
“Today’s news from the Bluetooth SIG is an exciting step forward for technology in mobile health and wellness devices,” said Rick Cnossen, president and board chair, Continua Health Alliance. “Our selection of Bluetooth low energy for the Continua Version Two Design Guidelines extends exciting new capabilities to manufacturers and consumers alike, as well as enabling additional use cases within the Continua ecosystem.”
“Nokia has been committed to this ultra low power wireless technology since its Wibree technology development. Now we are happy to see the adoption of the Bluetooth low energy specification, which will open up new market opportunities and space to innovate for the industry. The wide manufacturer base behind Bluetooth low energy technology and the combined industry effort will result in exciting new user experiences in the mobile space,” said Markku Verkama, Director, Devices R&D Nokia.
Bluetooth low energy wireless technology, the hallmark feature of the V4.0 Bluetooth Core Specification, features:
· Ultra-low peak, average and idle mode power consumption
· Ability to run for years on standard coin-cell batteries
· Low cost
· Multi-vendor interoperability
· Enhanced range
This enhancement to the Bluetooth Core Specification allows two types of implementation, dual-mode and single-mode. In a dual-mode implementation, Bluetooth low energy functionality is integrated into an existing classic Bluetooth controller. The resulting architecture shares much of classic Bluetooth technology’s existing radio and functionality resulting in a minimal cost increase compared to classic Bluetooth technology. Additionally, manufacturers can use current classic Bluetooth (Bluetooth V2.1 + EDR or Bluetooth V3.0 + HS) chips with the new low energy stack, enhancing the development of classic Bluetooth devices with new capabilities.
Single-mode chips, which will enable highly integrated and compact devices, will feature a lightweight Link Layer providing ultra-low power idle mode operation, simple device discovery, and reliable point-to-multipoint data transfer with advanced power-save and secure encrypted connections at the lowest possible cost. The Link Layer in these controllers will enable Internet connected sensors to schedule Bluetooth low energy traffic between Bluetooth transmissions.
Technical Details
§ Data Transfers – Bluetooth low energy supports very short data packets (8 octet minimum up to 27 octets maximum) that are transferred at 1 Mbps. All connections use advanced sniff-subrating to achieve ultra low duty cycles.
§ Frequency Hopping – Bluetooth low energy uses the adaptive frequency hopping common to all versions of Bluetooth technology to minimize interference from other technologies in the 2.4 GHz ISM Band. Efficient multi-path benefits increase the link budgets and range.
§ Host Control – Bluetooth low energy places a significant amount of intelligence in the controller, which allows the host to sleep for longer periods of time and be woken up by the controller only when the host needs to perform some action. This allows for the greatest current savings since the host is assumed to consume more power than the controller.
§ Latency – Bluetooth low energy can support connection setup and data transfer as low as 3ms, allowing an application to form a connection and then transfer authenticated data in few milliseconds for a short communication burst before quickly tearing down the connection.
§ Range – Increased modulation index provides a possible range for Bluetooth low energy of over 100 meters.
§ Robustness – Bluetooth low energy uses a strong 24 bit CRC on all packets ensuring the maximum robustness against interference.
§ Strong Security – Full AES-128 encryption using CCM to provide strong encryption and authentication of data packets.
§ Topology – Bluetooth low energy uses a 32 bit access address on every packet for each slave, allowing billions of devices to be connected. The technology is optimized for one-to-one connections while allowing one-to-many connections using a star topology. With the use of quick connections and disconnections, data can move in a mesh-like topology without the complexities of maintaining a mesh network.
Bluetooth Technology in Telehealth Solutions
Today’s announcement also advances the requirements of the Bluetooth SIG’s agreement with Continua Health Alliance, the industry coalition of leading health care and technology companies charged with establishing a system of interoperable personal telehealth solutions. Continua has voted to include the Bluetooth low energy wireless technology specification, Bluetooth low energy, in Version Two of its Continua Health Alliance Design Guidelines. The selection of Bluetooth low energy extends the current Continua standard for the Bluetooth Health Device Profile, the only wireless technology specification included in Continua’s Version One Design Guidelines.
