Smart Campus – University Wi-Fi Installation

University Wi-Fi Installation

The Result

Campuses are challenging environments for wireless networks because of the campus size, and high user capacity. Altai’s patented Super WiFi solution provides the coverage, user density, security and bandwidth that was required for this University Wi-Fi Installation – not just for today, but scalable to accommodate future growth. The next stage of the network expansion plan will be kicked-off in the first half of 2018 to cope with the increasing number of users expected.


Established in 1990, the Ibn Zohr University (Université Ibnou Zohr “UIZ”) is a public higher education institution located in Agadir , Morocco.

The initiative to deploy a Wi-Fi network throughout the campus of the Faculty of Science was to enable various mobile applications within the campus, and encourage interactive learning amongst students and professors.

The university approached an Altai Super Wifi partner in Morocco to conduct a site survey and recommend a wireless solution that would provide both students and staff with fast and reliable connectivity across its campuses.

After several trials against competing products, Altai’s Super WiFi Solution was quickly identified as the best-fit solution – it was proven effective in many schools and universities across different regions around the world. The award-winning Altai Super WiFi Solution has significantly improved the Wi-Fi signal coverage by 10 times per access point and 5 times the capacity to provide 100% indoor and outdoor coverage.

The Challenge

  • Very dynamic environment with specific requirements due to the huge campus size, high user capacity and high network security
  • The wireless network covers both indoor and outdoor areas with both needing reliable coverage
  • Deployment had to be fast and unobtrusive plus scalable to grow with requirements and the University size

The SolutionUniversity Wi-Fi INstallation

With various antenna downtilt on different sectors, the Altai A8ns’ were installed on light poles to provide large area outdoor Wi-Fi coverage while C1ns’ are used as CPE’s (Customer Premise Equipment) to extend the Wi-Fi signal from outdoor to indoor areas.  Altai A2s’ were installed to provide micro coverage in some corner areas.

In order to manage the network effectively, all the access points were connected with the Altai Wireless Management System (“AWMS”) for network management and monitoring.

The Result

The Altai super long range Wi-Fi technologies provide extensive network coverage for the whole university. The new wireless network has enabled many new mobile applications and encourages communications among students and professors.

What is Wi-Fi CERTIFIED Passpoint ™?

Wi-Fi CERTIFIED Passpoint™ – Transforming the Wi-Fi Hotspot Experience

Networks utilised, installed and promoted by PowertecWifi are all developed with Passpoint and support Wi-Fi roaming and industry standards.

Wi-Fi CERTIFIED Passpoint ™ launched in 2012 as an industry-wide solution to streamline network access in hotspots and eliminate the need for users to find and authenticate a network each time they connect.

In Wi-Fi networks that do not support Passpoint, users must search for and choose a network, request the connection to the access point (AP) each time, and in many cases, must re-enter their authentication credentials.

Passpoint automates that entire process, enabling a seamless connection between hotspot networks and mobile devices, all while delivering the highest WPA2™ security. Passpoint is enabling a more cellular-like experience when connecting to Wi-Fi networks

Passpoint was developed in Wi-Fi Alliance® through partnerships between mobile device manufacturers, network equipment vendors, and operators. Passpoint reflects the depth and breadth of that collaboration as a great solution for end users, network operators, and device vendors.

Wi-Fi Deployment in Underserviced Area

Wi-Fi Deployment in an Underserviced Wi-Fi Area

Cost Effective Solution for Wi-Fi Hotspots

This case study has particular relevance to many parts of Australia currently also experiencing underserviced Wi-Fi areas.

Application:  Free WiFi hotspots for local residents in under-serviced wi-fi areas

Products used: Altai A8-Ein, A2-Ei, A2, A2e, C1n and AltaiCare

Result: The Altai Super WiFi hotspots covers a total of 225 areas such as government buildings, schools, taxi ranks, clinics, police stations, internet cafes etc. At peak hours, there are over a thousand of simultaneous users with an average speed of 15Mbps per user.

Deployment Location: Dr. Kenneth Kaunda District Municipality, South Africa

In South Africa, the lack of affordable, reliable, high speed broadband access has negatively impacted the country’s development. The high cost of communication has constrained investment in South Africa as a regional business hub.

To improve the broadband penetration of the country, South Africa Connect, a national broadband policy, has been implemented.

Telecommunication Holdings (Pty) Ltd (“Galela”) offers internet connection services in underserviced wi-fi areas of South Africa including townships and rural areas. Galela has successfully deployed a WiFi hotspot network in one of the large District Municipalities in South Africa, Dr. Kenneth Kaunda District Municipality (“Dr.KKDM”).

An Altai Super WiFi solution was chosen for the network deployment as it requires fewer base stations and access points persquare kilometre. Altai Super Wifi Solution uses a patented long range technology. This technology significantly lowers the total project cost and shortens the deployment time.

The WiFi service in Dr.KKDM was launched in February of 2016; it provides free internet connectivity to local residents. The rollout is part of the South Africa Connect program to provide fast, reliable and secure internet to all citizens.

Phase two of this program will cover all the provinces in the north-western part of South Africa; it is targeted to be completed by the second quarter of 2016.

The Challenge

  • Large area coverage with many WiFi hotspots scattered around the district
  • A large number of simultaneous users
  • Lack of Ethernet backbone

The Solution

Owing to the huge coverage area and high user capacity, Altai A8-Ein and A2-Ei are deployed on the rooftops of various buildings to provide WiFi access while C1n’s are used as CPE’s to extend the WiFi coverage. In some areas such as internet café s, schools and clinics, A2 and C1n are used to provide small area wireless networks.AltaiCare Logo_High Resolution

The operator used AltaiCare; a cloud-based network management solution that manages the WiFi network and configuration, due to many base stations and access points installed in different locations. This helps the service operator to manage the network more efficiently.

The Result

There are 225 WiFi hotspots in the city of Tlokwe located in the Dr. KKDM. The WiFi hotspots are deployed mostly in underserved areas such as townships and settlements. At peak hours, there are over a thousand simultaneous users with an average speed of over 15Mbps per user. The local residents can now enjoy 24×7 seamless WiFi services for free.

Wi-Fi speeds set to triple on the back of a WAVE?

Wi-Fi speeds set to triple?

The Wi-Fi Alliance® recently announced they were expanding their 802.11ac specification to include new features – the most exciting being the MU-MIMO. These upgrades promise an increase in Wi-Fi speeds of up to 3x.

The features enable wi-fi to ‘more efficiently handle high-bandwidth applications from an increasing number of smartphones, tablets, TV’s and other devices simultaneously connected to wi-fi networks.’  This is good news, with greater capacity and greater speeds for all users.

The most anticipated new feature is MU-MIMO – Multi-user Multiple Input Multiple Output – which allows more devices to operate simultaneously on the same network without sacrificing speed or performance.  Just think of the benefit where currently Wi-Fi access points are only able to be utilised one at a time.


The new features are:

  • MU-MIMO: Networks with MU-MIMO are capable of multitasking by sending data to multiple devices at once rather than one-at-a-time, improving overall network efficiency and throughput
  • 160 MHz channels: Wi-Fi CERTIFIED ac increases the maximum channel bandwidth from 80 MHz channels to 160 MHz channels, potentially doubling transmission speeds
  • Four spatial streams: Device speeds are proportional to the number of spatial streams. Wi-Fi CERTIFIED ac now includes support for four spatial streams, up from three spatial streams.
  • Extended 5 GHz channel support: Wi-Fi CERTIFIED ac encourages device support for a greater number of available channels in 5 GHz. Support for additional channels makes more efficient use of available spectrum and reduces interference and congestion by minimizing the number of networks operating on overlapping channels.

What is Altai doing to cater for the upgraded 802.11ac specification?

Altai are set to release a range of Wave2 indoor and outdoor products starting from the 3rd quarter of 2016 which will utilise the new and improved specification.

Product information will be provided at launch but at Powertec is available to assist with any queries in the meantime.



Wi-fi Network Topology Using Altai VLAN

We are often asked if Altai SuperWifi products can support VLAN’s – the answer is yes!

A virtual local area network (VLAN) is a logical group of workstations, servers and network devices that appear to be on the same LAN despite their geographical distribution. A VLAN allows a network of computers and users to communicate in a simulated environment as if they exist in a single LAN and are sharing a single broadcast and multicast domain. VLANs are implemented to achieve scalability, security and ease of network management and can quickly adapt to change in network requirements and relocation of workstations and server nodes.

Higher-end switches allow the functionality and implementation of VLANs. The purpose of implementing a VLAN is to improve the performance of a network or apply appropriate security features.




We recently worked alongside a Powertec Channel Partner in NSW to set up a wifi network for their government client who had a number of sites needing to be connected and requiring multiple layers of access, security and routing configurations within each site. At each site there are 3 (SSID’s) and each of them serves a specific network service and purpose.

The Altaicare cloud management system was deployed to provide network management and differing levels of Authentication for Wi-Fi users.

  • SSID 1 for general public access internet usage, with monitored bandwidth, data allowance and secure internet access for groups of users.
  • SSID 2 was for administrative purposes with a suppressed SSID. Other users will not be able to discover this network and it is the only one that allows access to business equipment utilised by staff. It was routed via the pre-existing Corporate Network
  • SSID 3 was the management VLAN for the wireless backhaul, AP and network management.
SSID VLAN Traffic Priority Authentification Encryption Bandwidth Control
1 102 Normal Captive Portal (and optional MAC address) Open Multiple Preset Accounts for Bandwidth and Data Allowances
2 101 Normal WPA2-PSK AES Corporate Users Via Citrix
3 1 Normal WPA2-PSK AES No Bandwidth Control


Altai Products Used in this Configuration

2 x A8n – The world’s leading 802.11n WiFi outdoor access point optimized for maximum coverage and highest throughput from a minimum number of installation sites. The Altai A8n has been designed to provide industry best coverage and capacity without complicated networking protocols or the need for a high density of transmitters.

The A8n is a multi-radio base station utilizing 8×8 MIMO smart antenna technologies and a patented signal processing algorithm to provide the industry’s best coverage per base station, especially in non-line-of sight (NLOS) environments. The multiple antennas of the A8n can be configured to provide coverage that is optimised for area, pattern and elevation. The multi-beam antennas of the A8n is designed to provide up to 3 times the range and 10 times the per site coverage as standard access point. Accordingly, up to 90% fewer installation sites for the same coverage area

2 x A2 – The Altai A2 WiFi Dual-band Access Point is designed to be used in Altai Super WiFi systems to provide 2.4 and 5 GHz dual-band dual-concurrent access coverage for both outdoor and indoor areas, and to increase system capacity, extend coverage, fill-in areas of low or blocked signals caused by obstructions.

    Wi-Fi Gold Coast Beaches?

    Four words for what we want – Wi-Fi Gold Coast Beaches

    With our headquarters based on the Gold Coast, Powertec staff are quite passionate about putting Wi-Fi on the iconic beaches of the City of Gold Coast (if not everywhere on the Coast) in order to move forward as a Smart City. We see the benefits as far reaching; those of health and safety by telling our visitors about surf conditions; to benefits for business’ by offering two for one icecream vouchers; and for those who log in to a city-wide system to share their happy snaps; and there are many other potential uses.

    We’re a city that’s all about tourism and attracting foreign visitors to holiday and study. The one thing they will all have in common is that they want to be connected to their families back home. They want to share their iconic Gold Coast centric experiences with their families…..and showcase our city to the rest of the world.

    And we are not the only ones who want the same thing apparently. Gold Coast Bulletin journalist Alice Gorman recently ‘wrote out’ about wi-fi after being slugged $70 for wi-fi access at her hotel accommodation by a legacy system (old and out of date extortionate wi-fi charging system) being run by her holiday apartment on the Coast.   We spoke to Alice after her initial article appeared and she wrote a follow-up article below:

    So we are ready and willing to speak to anyone who can make this happen – Wi-Fi Gold Coast Beaches.

    University deploys Altai Super WiFi Solution

    Altai’s super WiFi solution saved the campus from complicated, expensive and time consuming installation of cable wiring. Sanjiang University is located in the suburban area of Nanjing, China. It is the first private tertiary institution in Jiangsu province. With a floor area of over 100,000 m2, Sanjiang University has over 7,000 students.

    Sanjiang University has deployed Altai’s A8 Super WiFi base stations across its dormitory area. The network is constructed by Nanjing Putian and powered by Altai Technologies.

    Five Altai A8 base stations have been installed in the residence hall to provide reliable outdoor and indoor coverage. The wireless network, which is based on Alta’s super WiFi technology, has been rolled out across 14 buildings in the dorm areas, providing 100% indoor and outdoor coverage.

    The University Wifi Solution

    Five Altai A8 base stations have been installed on the rooftop of the buildings to cover 14 dormitories and outdoor areas.

    The Altai A8 base station has utilised both smart antenna technologies to increase the average signal-to-noise ratio (SNR) and signal selection diversity to improve signal performance under multi-path fading situation.

    The Result

    3 to 14 Mbps at 300 m NLOS is recorded, whereas standard AP only supports 0 to 2 Mbps at 200 m. -63 to -76 dBm outdoor and -61 to -72 dBm indoor signal strength are recorded. 1.3 km2 outdoor areas are covered with 1.3 Mbps. Packet loss is ≤1% and latency ranges from 3 to 10 ms, which is much better than before.

    Students can access stable and high speed Internet for free. 100% coverage in both indoor and outdoor areas is achieved.

    The wireless network helps enable interactive learning in the Sanjiang University.

    Altai’s super WiFi solution saved the campus from complicated cable wiring. The installation and deployment of the WiFi solution was completed in only one week.
