apa itu mimo? wireless speed upto 300Mbps

Mimo technology ? apa itu mimo technology ?

Wireless router mimo murah

MIMO bukanlah standar baru di area jaringan nirkabel. Tetapi dengan menggunakan MIMO, koneksi wireless akan lebih cepat dan jarak jangkauan juga akan semakin jauh. MIMO datang lebih cepat dari yang diperkirakan. Saat ini sudah ada empat perusahaan networking yang sudah memproduksi router dengan teknologi MIMO. Dengan harga yang tentunya sangat tinggi, router-router ini menjanjikan koneksi wireless yang jauh lebih baik ketimbang hanya mengandalkan standar yang sudah ada. Apakah benar router MIMO ini dapat meningkatkan daya jangkau dan kecepatan transfer jaringan nirkabel dari standar yang sudah ada? Seperti apa kerja MIMO dan berapa besar biaya yang harus ditanggung pemakainya? Pernahkah Anda mengalami di mana radio atau ponsel Anda tidak mendapatkan sinyal? Padahal lokasi tempat Anda berada adalah di pusat kota ataudekat dengan pemancar. Hal ini pasti disebabkan oleh adanya gangguan yang dikenaldengan sebutan Multipath.

What is IPv6? and Why do we need IPv6?

What is IPv6?

increasing number of Internet users, the limited IP4, IP6 has been no new generation of more flexibility, efficiency,capability, and optimized functionality That can truly meet ourever-Increasing needs.

People refer to IPv6 as “the next-generation Internet protocol,” and it was originally created as the answer to IPv4’s inevitable, looming address-exhaustion crisis.

Though you’ve probably heard a thing or two about IPv6 already, it has been improved even further in the quest to bring us the flexibility, efficiency, capability, and optimized functionality that can truly meet our ever-increasing needs.

Why do we need IPv6?

Because we need to communicate, and our current system isn’t really cutting it anymore—kind of like how the Pony Express can’t compete with airmail. Just look at how much time and effort we’ve invested in coming up with slick new ways to conserve bandwidth and IP addresses.
The amount of people and devices that connect to networks increases each and every day.

You can actually leave out parts of the address to abbreviate it, but to get away with doing that you have to follow a couple of rules. First, you can drop any leading zeros in each of the individual blocks. After you do that, the sample address from earlier would then look like this:

2001:db8:3c4d:12:0:0:1234:56ab

Okay, that’s a definite improvement—at least we don’t have to write all of those extra zeros! But what about whole blocks that don’t have anything in them except zeros? Well, we can kind of lose those too—at least some of them. Again referring to our sample address, we can remove the two blocks of zeros by replacing them with double colons, like this:

2001:db8:3c4d:12::1234:56ab
