What is 2G Spectrum?

2G is short for second-generation wireless telephone technology. Second generation 2G cellular telecom networks were commercially launched on the GSM standard in Finland by Radiolinja (now part of Elisa Oyj) in 1991. Three primary benefits of 2G networks over their predecessors were that phone conversations were digitally encrypted; 2G systems were significantly more efficient on the spectrum allowing for far greater mobile phone penetration levels; and 2G introduced data services for mobile, starting with SMS text messages.

First downloaded media content was also introduced in 2G phones. Ring tones were downloaded and paid for. Mobile advertising was also introduced when SMS was used for sending advertisements and short headlines of news.

Effect of 2G scam on Unitech projects

Wireless Home Theater

True wireless home theater is still the unattained ideal many home theater owners would love to achieve. But thanks to advancement in wireless technology, things are changing fast; wireless audio systems have become better, cheaper, faster, and easier to use and install.

However... As things stand today, the term 'wireless' in the audio and video world does not mean 'wireless' - it just means 'less' wires.

And this applies to any wireless speakers system presently available on the market.

Still, reducing the cable clutter can turn out to be a great advantage. Home theater systems are synonymous with a huge mass of home theater cables that are not only unsightly, but also difficult to troubleshoot should problems arise.

Concealing this mass of cables is surely not a straightforward job. This being especially so if you do not have pre-wired walls and ceilings for an in-wall home entertainment wiring solution. At the same time, simply running cables across the floor is far from recommended as these can easily become a serious tripping hazard for anyone in the house.

For these reasons, many find themselves stranded when upgrading from say a stereo set-up to a 5:1 surround, or wish to move from a 5.1 speaker setup to a 7.1 multi-channel solution.

Professionals can do the job for you but it will surely turn out to be expensive to retrofit a house, or in that case even a single room with an in-wall wiring solution for your audio and video systems. And this apart from that fact that such projects are often difficult to manage.wireless home theatre
