More wireless data

Imec and Panasonic have developed a 40nm low-power low-cost CMOS device implementing the IEEE 802.11ad standard – which transports high bandwidth data over a short range. At 7Gbps over short distances it is faster than the 5Gbps provided by USB 3.0.

High bandwidth short range wireless technology will enable many new applications for fast connections that are also intrinsically more secure than wider reaching networks. However this low power version requires more development before it is ready for commercial applications.

Quick SSD v HDD comparison

Capacity & price:
The OCZ Revodrive 3 x2 240GB SSD is less than 25% of the capacity of the Western Digital VelociRaptor 1TB HDD but costs about twice as much. So the SSD storage is roughly 8 times as expensive.

Read speed:
SSD 1520MB/s, HDD 200MB/s – SSD is roughly 7.6 times as fast.

Write speed:
SSD 1129MB/s, HDD 200MB/s – SSD is roughly 5.6 times as fast.

802.11ac Wi-Fi equipment available in June

Buffalo have announced their AirStation WZR-D1800H equipment will be available in June with 802.11ac. It includes a 2.4GHz 802.11n radio for backward compatibility.
Smallnetbuilder says the Buffalo WLI-TX4-1300H model will be 802.11ac only.
Netgear announce R6300 for 802.11ac

Is cloud the right choice?

The risk of interrupted access to data can be measured in terms of the amount of computing hardware and software it must pass through. So if the only or main data store and processing is by internet services, the risk to access is much higher. The same can be said of data security. Indeed, by UK law some data must be held with specific constraints that naturally militate against the main principle of the cloud, which is to delegate IT management, reducing IT to a set of benefits and business level decisions. Nonetheless, cloud solutions do present opportunities to do things that were difficult or impossible before, especially in terms of scalability and volatility of resource requirements.
All this raises an important question: Are cloud services a sound choice if more proximate services are an option?
I think the cases where cloud services are the only option are few. I also don’t believe that a substantial cost reduction is possible because of purchasing large amounts of equipment, especially when the costs of running a large organisation are taken into consideration. Locating services in economies with lower costs definitely has price advantages, but at the cost of access time and risk to access and security. I have noticed that where worthwhile cost reductions have been claimed it is often at the expense of IT jobs. As a result either the cloud provider must be adding a similar number of people and hence costs which will eventually return in service prices, or the services offered cannot be as well matched to the specific needs of the business. That standardisation of IT and hence business processes reduces the opportunity for business differentiation.
In the end there is no generic answer to the question. Care must be taken to make the right decision.

Better wireless chip improves possibilities

Low power Bluetooth and better battery life will allow users of mobile devices to leave Bluetooth running for longer. This makes connecting to Bluetooth beacons to find indoor location viable. Unfortunately the discovery phase of the Bluetooth protocol is slow limiting its usefulness as the device moves quicker.
Broadcom has announced their BCM4752 chip with support for 802.11ac and low-power Bluetooth. Naturally the new chip is smaller and uses less power.
