Full version of this newsletter with pictures: http://download.mikrotik.com/newsletter27.pdf ================================== *RouterBOARD 711 released* MikroTik is pleased to announce our new series of products, the RB711. These devices have a built-in high power 5GHz 802.11n radio, 10/100 Ethernet port, and a very affordable price of $49 that makes them the perfect choice for AP and CPE builders and MFM partners. The RB711 supports Nstreme and is compatible with R52 5/10MHz channels. Visit: www.routerboard.com Several models are available: - RB711-5Hn-M with MMCX connector - RB711-5Hn-U with uFL connector Also available is RB711A with more memory, and a Level4 license for AP support: - RB711A-5Hn with MMCX connector. ================================== *Trainings before the MUM in USA* MikroTik has many certified trainers around the world, we have personally trained each of them to make sure they provide the highest standard of RouterOS training possible. In the week before the MUM event in Arizona, our training partners will offer the following certified RouterOS courses: # Stephen R.W. Discher (RouterOS basics, MTCNA) http://www.learnmikrotik.com/index.php/phoenix.html # Butch Evans Consulting (RouterOS Wireless, MTCWE) http://store.wispgear.net/Consulting-and-Training-Classes/c35/p364/Mikrotik-RouterOS-Training-Before-the-MUM-2010/product_info.html # MikroTik (RouterOS internetworking, MTCINE) http://www.mikrotik.com/training/?training_site=mikrotik_trainings ================================== *MUM in Brazil, Colombia and USA* MikroTik User Meeting (MUM) is the best place to learn about new MikroTik products, see them in action, listen to professional presentations, take part in workshops, and meet other MikroTik users. Announcing two new MUM events this year! Currently registrations are open for these events: # Phoenix, Arizona, USA. September 30 - October 1, 2010 # Salvador, Brazil. November 11-12, 2010 # Bogota, Colombia. November 18-19, 2010 Register online and receive your entry ticket - both free tickets, and paid tickets are available. Free tickets don’t include lunch and RouterOS license. All attendees must register and print tickets before their arrival! Information about the MUM and online registration: http://mum.mikrotik.com/ ================================== *Nv2 wireless TDMA protocol* MikroTik has developed a new wireless protocol based on TDMA technology (Time Division Multiple Access) - Nv2 (Nstreme version 2). TDMA is a channel access method for shared medium networks. It allows several users to share the same frequency channel by dividing the signal into different time slots. The users transmit in rapid succession, one after the other, each using his own time slot. This allows multiple stations to share the same transmission medium (e.g. radio frequency channel) while using only a part of its channel capacity. The most important benefits of Nv2 are: - Increased speed - More client connections in PTM environments - Lower latency - No distance limitations - No penalty for long distances Starting from RouterOS v5.0beta5 you can configure Nv2 in the Wireless menu. - 5/10/20/40 MHz channel support - 802.11n MIMO Atheros AR92xx support - R52, R52H, AR5414 backward compatible - Mixed systems possible - Possibility to set CPE association priorities, so when AP switches to Nv2, all CPEs switch too, allowing easy migration and upgrade To make the connection using Nv2 on the AP side you need to select the wireless-protocol=nv2 and on the Station side, select wireless-protocol ‘Nv2’ or ‘any’. Currently, with 802.11n and Nv2 you can get approximately 97Mbps UDP traffic and 94Mbs TCP traffic through RB711 in one direction using one chain. More information on Nv2: http://wiki.mikrotik.com/wiki/Manual:Interface/Wireless#Nv27 ================================== *Nv2 latency examples* Starting with v5beta6, Nv2 has a new setting, which enables a special QoS mechanism to give priority to small packets, and improves link latency. ================================== *Multicore improvements* Starting with RouterOS v5beta6 RouterOS supports up to 16 cores in your PC system (previous limitation was 8), and has new Intel Ethernet drivers. It is possible to assign a different CPU for each IRQ of each Ethernet card to improve the performance and balance load. --
