The EDIMAX ac dongle-Triple your laptop’s Wi-Fi speed

In an age of streaming media and online gaming, Wireless-AC is not just a luxury: it is the networking standard you need and deserve. Upgrade your wireless device to dual-band 802.11ac with the fastest possible USB 3.0 connectivity for blistering Wi-Fi speeds on the interference free 5Ghz frequency band. The EW-7833UAC’s high performance 3T3R MIMO technology provides super-high speeds of up to 1300Mbps and is backwards compatible with 802.11a/b/g/n wireless devices. Easily Upgrade to Fastest 11ac Wi-Fi Compatible with the 802.11ac standard and delivering speeds of up to 1300Mbps at 5GHz – almost three times as fast as 802.11n together with USB 3.0 connectivity. Upgrade PC’s and notebooks to super high speed 802.11ac Wi-Fi and enjoy streaming video and data at lightning speeds. Faster Wi-Fi with Beamforming Technology Beamforming technology involves signal processing algorithms that generate directional signals, focused towards each client. Signals don’t radiate out into the atmosphere, but are concentrated from your router or access point to the target device. With beamforming reception support in your adapter, Wi-Fi performance is dramatically improved with better reliability, range and coverage and less wasted signals. High Performance 3T3R MIMO Technology The EW-7833UAC features multiple input, multiple output (MIMO) antenna technology with 3 transmitter antennas and 3 receiver antennas to optimize data speeds for the best wireless performance. 802.11ac Truly Realized with USB 3.0 USB 3.0 is up to 10 times faster than USB 2.0 and specifies a maximum transmission speed of up to 5Gbps. Providing quicker data transmission times, and backwards compatibility with USB 2.0 (which specifies a maximum speed of 480Mbps), USB 3.0 is the new standard in connectivity...

E-Band-Everything You Need To Know

E-Band-Everything You Need To Know

ICASA has made the very affordable PtP spectrum (E-Band) available on a self-registration basis. Below is a guideline and procedure for radio spectrum application in the E-Band What is E-Band? E-Band is the pairing of 71-76GHz with 81-86GHz; ICASA has split this into two blocks: Block A: 2.5GHz paired of light-licensed spectrum (73.5GHz-75.75GHz & 83.5GHz-85.75GHz) Block B: 2GHz paired of licensed spectrum (71.25GHz-73GHz & 81.25GHz-83GHz) What is it used for? E-Band is used for high-capacity, narrow beamwidth PtP links Who can apply for links in the E-Band? Holders of ECNS licenses valid for the area in which both points of a link is to be deployed Holders of ECNS license exemptions such as private electronic communications networks How do I apply for it? Links in the licensed portion-Block B-are applied for in the normal way using the standard application procedure. Links in the light-licensed portion-Block A-are registered on a first-come-first-served basis using the self-registration process set out below. What are the annual fees? The annual radio frequency spectrum fee for using E-Band spectrum is levied as the Minimum Fee per annum per link per hop based on 2x250MHz channel or multiples thereof. The Minimum Fee for 1 April 2017-31 March 2018 is R 134.00. For example: a 500MHz link will have an annual fee of R268.00 (R 134.00xtwo channels) Fees are charged pro-rata based on the date of registration (Block B) or license issue date (Block A). Note that the minimum fees are revised on an annual basis and are published as an amendment to the Radio Frequency Spectrum Fees Regulations. See http://www.ellipsis.co.za/radio-frequency-spectrum-fees/ for current figures. Self-registering links in...
How an Outdoor Wireless company entered  the Enterprise Wi-Fi market

How an Outdoor Wireless company entered the Enterprise Wi-Fi market

Article by Robert J. Pera, founder of Ubiquiti Networks, Inc.  Perhaps now hard to believe, Ubiquiti’s decision to enter a new market with the introduction of UniFi in 2010 was generally criticized. At that time, some questioned why a company driving explosive growth in the outdoor Wireless Internet Service Provider Industry would risk diverting their focus. Others questioned how Ubiquiti, having less than 25 employees and none of them marketing or sales people, could possibly enter a market dominated by traditional sales models. Nevertheless, I saw an Industry ripe for disruption and a perfect opportunity for us to leverage our core strengths. Exactly why was it so compelling? In 2009, if you took apart a $1,000+ “Enterprise WiFi” AP and compared it to a <$50 consumer WiFi AP, you would see 90% component/material overlap. Enterprise vendors were essentially over-engineering consumer WiFi reference designs for often little more than incremental performance benefit and then dramatically over-charging for them. Ubiquiti’s past success was attributed to a completely opposite philosophy — making designs more cost-efficient (while enhancing performance) and passing savings on to the customer. And our increasing economy of scale at this point (1mm+ AirMax radios/ yr) reinforced what I saw as an excellent Enterprise WiFi opportunity. I believed a solution at just a fraction of the cost combined with a basic features set and some “Ubiquiti magic” would find its way to disrupting the market and breaking the established IT sales dynamics. What exactly do I mean by “Ubiquiti magic?” Well, market timing and cost-disruption alone do not make a disruptive product. If they did, then many vendors focused on...
