Mobile success factors :-

January 7th, 2013 No comments

Mobile cellular penetration in LDC

Over the last decade, no other ICT has grown as fast as mobile cellular telephony and connected previously unconnected people in such a short span of time. There are a number of factors that have made the mobile boom possible:

  • Competition: The introduction of second-generation technology opened up greater opportunities for new market entrants due to increased capacity and better spectrum efficiency. Most countries introduced competition with the launch of GSM networks. For many countries, this was their first taste of competition in the telecommunication sector. Competition has lowered prices, increased the quality and number of services and expanded coverage, creating the right conditions for mobile communications to grow. As of 2009, 90 per cent of countries worldwide allowed either partial or full competition in their cellular mobile market. The same degree of competition is found in the Least Developed Countries, although the level of partial competition –in which markets limit the number of mobile cellular operators to two– is slightly higher
  • Common technology: Europe established a common regional standard for second- generation digital mobile technology – Groupe Spécial Mobile (GSM) – over a quarter century ago. This led to a de facto global standard for 2G mobile technology. The first GSM network was launched in Finland in 1991, and Australia became the first non-European country to join the GSM Association two years later. By June 2009, GSM accounted for four out of every five mobile subscriptions around the world and today, nearly 800 operators in over 200 countries operate GSM networks.16
  • Prepaid subscriptions: The introduction of prepaid billing in 1996 brought mobile to the masses. There are millions of people around the world who would not qualify for a postpaid mobile plan, let alone be able to afford the required monthly payments. The majority of subscriptions in developing countries are prepaid, and in LDCs, where income levels are particularly low, 94 per cent of subscriptions were prepaid at the end of 2009. To cater to low-income users, operators have adopted new business models by offering, for example, low denomination airtime recharges and per second billing.
  • Applications: The growing number of mobile applications has increased demand and usage. Roaming, text messaging and mobile broadband have become desirable applications for a growing number of people, including in LDCs. Since Internet penetration remains relatively low, mobile applications can help overcome Internet access barriers.
  • Equipment: Mobile equipment, both on the network infrastructure side as well as devices, has grown in sophistication while continuing to drop in price. The emergence of Chinese equipment vendors, such as Huawei and ZTE, has driven competition in the infrastructure segment, dramatically reducing the cost of installing a mobile network. Innovations in handset technology include the development of sophisticated smartphones, which are driving demand for mobile data services. In low-income countries, falling prices of low-end mobile phones continue to make access more affordable.

Mobile telephony has also improved public telephone access, and mobile public access can help operators achieve universal access goals. It has also generated new business models, where owners of mobile telephones re-sell the service to others.

In some countries, the increasing number of mobile cellular subscriptions is actually reducing the need for public access since most people either own or have access to a mobile phone specially in smaller Nations like Maldives.

BLAKE2 Claims Faster Hashing Than SHA-3, SHA-2 and MD5

December 25th, 2012 No comments

BLAKE2 has been recently announced as a new alternative to the existing cryptographic hash algorithms MD5 and SHA-2/3. With applicability in cloud storage, software distribution, host-based intrusion detection, digital forensics and revision control tools, BLAKE2 performs a lot faster than the MD5 algorithm on Intel 32- and 64-bit systems. The developers of BLAKE2 insist that even though the algorithm is faster, there are no loose ends when it comes to security. BLAKE2 is an optimized version of the then SHA-3 finalist BLAKE.”

iPhone 5 vs Samsung Galaxy Note 2: spec comparison

October 21st, 2012 No comments

Size & Weight

The 123.8 x 58.6 x 7.6mm iPhone 5 may be taller than any of its predecessors, but it will look positively dwarf-like against the jumbo Galaxy Note 2. Samsung’s model measures up at 151.1 x 80.5 x 9.4mm, making you far more aware of its pocket-presence than the iPhone. Its 180g weight is 68g more than Apple’s new phone, a gap that could easily have been larger given the size of the Note, so credit to Samsung for keeping such a large device fairly nimble.

Display

With a giant 5.5in screen, the Note 2 plays more heavily on the visual element, even if the iPhone’s new 4in display will be deemed ample by most. The latter’s resolution should appear tighter to the trained eye, with its 1136 x 640 pixels and density of 326 PPI, going against the Note’s 1280 x 720 pixels and 267 PPI. The HD Super AMOLED Plus technology used on the Note’s face has been heralded for its quality, but expect the iPhone 5’s IPS LCD to produce images and words that little bit crisper.

Storage & Memory

Both of these high-spec devices come in 16GB, 32GB, and 64GB models. But, crucially, for those who want to go to town on the file storage, the Galaxy Note 2 has a microSD card slot unlike the iPhone 5, allowing expansion by a further 64GB for a whopping 128GB in total. Samsung’s oversize phone also has an impressive 2GB of RAM; a stat that hasn’t been confirmed for the iPhone 5. Will it match up to its rival in this department?

Processor

Among the gaps left in Apple’s launch presentation were the real nitty-gritty details of the iPhone 5’s A6 processor. The consensus seems to point to a dual-core engine, which would put it in the shade of the Note 2’s powerful quad-core Exynos 4412, which clocks in a highly commendable 1.6GHz.

Software

Here, we are faced with the crème-de-la-crème in mobile software battling it out for supremacy. The latest iteration of Apple and Android’s market-leading operating systems sees iOS 6 face up to 4.1 Jelly Bean. Both list a wealth of features; both have pulled in strong reviews. Usually, operating systems come down to personal preference, but perhaps Apple’s slightly more extensive app store to Google Play, just gives the iPhone software victory by a whisker.

Camera

We’re splitting hairs in this category. The rear camera on both devices are 8-megapixel affairs, with 3264×2448 pixel resolution, recording video in 1080p at 30 frames per second. But just giving the Galaxy Note 2 the edge is its 1.9-megapixel front-facing camera, that will be slightly superior to the iPhone 5’s 1.2-megapixel front cam when it comes to video calls and the like.

Cheap new Chromebook from Samsung revealed

October 20th, 2012 No comments

Google has unveiled a new Chromebook laptop with an affordable price tag, calling it “the computer for everyone”.

The model, made by Samsung, has an 11.6-inch screen with 1366 x 786 resolution, an ARM Cortex-A15 processor, 2GB of RAM and 16GB of flash storage. There’s also Bluetooth 3.0, three USB ports (one of which is USB 3.0), SD card slot and 100GB of free cloud storage available through Google Drive. Google says there’s 6.5 hours of battery life.

The Chromebook is thin and light: a mere 20mm thick and 1.1kg in weight. Also on the light side is the price tag of just £229.

For an 11.6-inch laptop capable of performing all the basic tasks like web browsing, word processing, video playback etc., that’s a steal. Critics will note that the new Chromebook is less powerful on paper than the Samsung-made Series 5 Chromebook unveiled back in June, which boasted 4GB of RAM and a 12.1-inch screen. There’s also something of a discrepancy between the UK and US prices: the Chromebook costs just $249 in the US, which converts to around £155 at today’s exchange rate.

The new Chromebook will be sold at PC World and Currys in the UK.

Does the new model appeal to you as a second computer, or possibly one for the kids to use? Let us know in the comments box below.
