Can I use 60GHz for PtP or PtMP links in the UK ?

Wireless Wire Dish

The arrival earlier this year of the MikroTik Wireless Wire and shortly after the MikroTik Wireless Wire Dish caused a large amount of excitement in the WISP industry and sales have proven them to be very popular products.  The use of 60GHz instead of 5GHz for point to point and point to multi-point links opens many new possibilities and challenges.

60GHz offers substantially less interference and much higher throughput speeds. Less interference because the band is almost completely unoccupied, uses very narrow radio antenna beams therefore offers much higher co-located frequency re-use. Also much higher throughput is possible up to as high as 1Gbps Full Duplex.

Wi-Fi Protected Access 3 – WPA3

Back in January 2018, the Wi-Fi Alliance announced in their Press Release that a new Wi-Fi Protected Access®  (aka WPA) certification program had been launched. First there was WPA™, then there was WPA2™, unsurprisingly therefore the new system was called WPA3™. (Note that WPA, WPA2 and WPA3 are not ‘standards’, nor are they ‘protocols’, they are ‘Wi-Fi Alliance certification programs‘. In fact, the standard for WPA2 was actually 802.11i).

What is a WISP?

WISP is a Wireless Internet Service Provider; they normally use wireless networking technology to offer customers with poor or non-existent broadband coverage, access to superior broadband speeds. These customers tend to live in areas where their broadband coverage is less than adequate, often located in more rural areas of the country where there is no fibre optic cable infrastructure already in place.

What’s the difference between the 802.11ac WiFi standard and previous versions?

The 802.11ac WiFi standard was introduced to enable more reliable and higher performance networking tasks like streaming HD video, playing online games without lag, or migrating large amounts of data in a shorter time span. Compared to the previous 802.11n WiFi standard, it uses a wider RF bandwidth up to 160 MHz (instead of 40 MHz) and allows the use of up to 8 x MIMO streams (instead of 4).

What is MIMO Wireless Technology?

MIMO – Multiple-Input Multiple-Output is a technology utilised in some WiFi products that uses multiple antennas to transmit and receive wireless signals; This usually leads to a stronger, more reliable signal when compared to single antenna alternatives.

MIMO is actually a combination of two technologies – SIMO (Single-Input Multiple-Output) and MISO (Multiple-Input Single-Output). When MIMO combines these two wireless systems, it does so by using multiple antennas to both send and receive signals. This usually leads to a stronger, more reliable signal when compared to single antenna alternatives.

News: MikroTik and Ubiquiti fix WPA2 Client Vulnerability

For those unfamiliar with this latest WPA2 Security Vulnerability, please bear in mind the problem is on the client device, not the AP. Therefore rushing to patch your APs is not going to solve all the problems in your network from this vulnerability!

Of course, if you’re using WPA-TKIP (or using ‘both’ TKIP and AES), you DO have more problems than this attack. Therefore please ensure that any support for TKIP is disabled!  If you’re using WEP, this vulnerability will not affect you, but then again, you have even bigger problems anyway!

New UAP AC Range

AC Range

 

The UAP-AC-Lite

The AC-Lite is the entry-level product for Ubiquiti’s new range of AC access points. As the name suggests it is both the smallest and lightest of the UAPs measuring just 160 x 160 x 31.45 mm and weighing in at 170g (185g with the mounting kit). It boasts speeds of up to 300Mbps on the 2.4GHz band and 867Mbps on the 5Ghz band, and a maximum range of 125m (400ft).

Ubiquiti UniFi UAP-AC-LITE and UAP-AC-LR now in stock

Introducing the new UniFi AC APs

AC Range

The UniFi AC Lite AP features a cleaner design in a reduced footprint – half the size compared to the standard UniFi AP.
Design

Innovative Antenna Design

The innovative antenna design provides a long-range, symmetrical-link coverage area, and the antenna gain of the UniFi AC LR AP performs better than one-way, high transmit power does for connecting distant clients.

HowTo: Updating the LiniTX Controller and Unifi Software

Controller Logo

 

The LinITX embedded controller has proven popular since its launch with many units sold. All feedback has been taken on board and alterations have been made to the embedded OS and configuration to make the controller as easy to use as possible. All new controllers purchased in 2015 will include Webmin as standard which will provide a web Gui interface to the OS settings. The controller now includes automatic tasks, the most important of which automatically reboots the controller daily at midnight which frees up resources and reduces problems with Java.
