E-lins’s latest network upgrade, ‘LTE Advanced’ (built by Sierra FDD and ZTE TDD),‘LTE Advance’ uses a technology called ‘carrier aggregation’ which allows mobile signals to be carried across different spectrum simultaneously. Currently, access to E-lins’s Advanced network, which will be rolled out commercially beyond Tech City early next year.
The new network we’re switching on in Tech City uses the spectrum that we acquired in the Ofcom spectrum auction earlier this year, and is the first part of an infrastructure that can meet the future demands of an increasingly data-hungry nation.

what’s openwrt?

文章目录 : 技术相关

What’s openwrt? in my mind,openwrt is running on the embedded device linux systems.
OpenWrt file system is writable, developers do not need to recompile after each modification,
Make it more like a mini Linux computer systems, but also accelerated the development speed.
You will find both the ARM, PowerPC, or MIPS processor, has a very good support.
And with around 3000 packages, users can easily customize the features to make the firmware.
Can be easily ported to various types of functions under openwrt.

What’s HSPA+?

文章目录 : 技术相关

HSPA+ is a network.HSPA+ (High Speed Packet Access Plus) is the name of the set of HSPA enhancements that are defined in 3GPP beyond Release 6 (R6). The enhanced downlink (HSDPA) was defined in R5 and the enhanced uplink (HSUPA) was defined in R6.
HSPA+ is an enhanced version of high-speed 3G wireless networks. Because it is so closely related to 3G and is not a new, built-from-the ground-up technology, HSPA+ has been called a 3.5G network instead of a true 4G network. But HSPA+ networks are capable of delivering 4G speeds, with download speeds between 5 megabits per second and 8 mbps.

This means that when you use an HSPA+ enabled device to access the internet, pages will load even quicker than normal on your phoneor computer – and you can expect faster downloads too.

Key Features of HSPA+:

It increases HSPA capacity as well as reduce latency below 50 milliseconds
It supports voice and data services on the same carrier and across all of the available radio spectrum and offers these services simultaneously to users
HSPA+ with 64 QAM and advanced antenna techniques such as 2X2 MIMO can deliver 42 Mbps theoretical capability and 11.5 Mbps on the uplink and could be ready for deployment in 2010
HSPA+ enhancements are backward-compatible with UMTS Release 99/Release 5/Release 6
HSPA+ could match, and possibly exceed, the potential performance capabilities of IEEE 802.16e-2005 (mobile WiMAX) in the same amount of spectrum, and could match LTE performance when using 5 MHz of spectrum.

4 reasons why 4G hasn’t scale up in India

4 reasons why 4G hasn’t scale up in India
One,Challenges for deploying 2300 MHz TD-LTE: The spectrum band licensed for BWA in India (TD-LTE on 2,300 MHz) has only been deployed in around 20 countries including Hong Kong, Australia and South Africa; the band lacks ecosystem support, device choices and network scale. Of the overall 1,000 devices launched by manufacturers for LTE, only 100 are suitable for the mode licensed in India. As a result, Indian operators have had to consider offering LTE services to a Wi-Fi router which in turn connects Wi-Fi-ready devices. The band is also weaker in offering in-building coverage compared to other modes of LTE.
Two, Better backhaul: Backhaul connections currently lack the coverage and quality required to render 4G services effective. Without the backhaul service to carry data at the same speed, the benefit of the 100 mbps connectivity offered by 4G cannot be realised by the end user. Over the last few years, Indian operators have invested heavily in rolling out fibre; we are now beginning to see scale and agreements falling into place.
Three, Combining data with voice: The advantage of offering super-high-speed data connectivity bundled with mobile voice is that the 4G service needn’t have to compete directly with fixed alternatives on price alone. Telecom regulations now allow an entity to hold a universal access licence to offer mobile voice. So, provided the BWA player has access to voice spectrum, it can now bundle high speed data and voice together.

Four,Capital constraints: A number of operators have put priority on deploying 3G first, due to capital and management constraints. And, in general, India’s capex to sales ratio has come down to 12-14 percent, while it is 22-25 percent for other emerging Asian countries such as China.

Industrial Wireless:Beware of COTS

Industrial Wireless:Beware of COTS, This is a tip of  Broken Signal Solutions.

Just because 802.11 is a commercial off-the-shelf (COTS) standard doesn’t mean that COTS products can be used in the industrial environment, warns Advantech’s Lochhaas. Industrially hardened access points “will survive in the industrial environment when exposed to extremes of temperature, dust, humidity, hazardous vapors and other common situations,” he says. “So when selecting your industrial wireless products, be certain to determine their suitability for the service you wish to use them in.”

E-lins notes, “Industrial environments are harder on wireless than any office would ever be,” which can drastically shorten the useful lifespan of wireless equipment. You get what you pay for in this world, and using office-grade networking equipment to save small amounts of money upfront will turn out to be a huge mistake when you have to pay for it later with downtime and repairs.”

E-lins’s comments could serve as a handy maxim to guide your approach not just to COTS components, but to wireless implementation in general.

Enable-Network To A Bus

文章目录 : 技术相关

E-lins H685 and H820 router Application in Sydney’ bus.E-lins Perfect solution when we’re dealing with a constantly moving, rattling bus!

E-lins  Wireless has been dealing with that problem recently. It’s supplying the on-bus 3G Wi-Fi routers for Sydney’s Opal transport smartcard, which is supposed to catch NSW up to the rest of the nation by actually introducing a work on-train smartcard.

As part of a supply contract with Opal’s main developer Cubic Transportation Systems to fit out 5000 Sydney buses, E-lins had to customise one of its existing designs. Many of the features on the router would be recognisable in most networking contexts: it has eight on-board ports, and can switch between using Telstra’s 3G networks when on the road and Wi-Fi signal when in maintenance areas. But it also required some changes.

“We’ve specialised the device so that it copes with vehicles being turned on and off which can cause spikes and currents in the available power,” E-lins Wireless’s Evan zou told us. “It’s also vibration-proof.”

The bus rollout is currently half-completed (though only two routes in Sydney are active), and scheduled to finish by the end of 2014.
