Surprising places with Wi-Fi

The availability of free Wi-Fi is no longer restricted to cafes, bars, restaurants, airports, shopping malls, pubs or hotels.  As the world goes hi-tech, you will be able to find free internet at places where you least expect it. Here are some unusual places across the globe where you will find free Wi-Fi.

Mount Everest Peak

The world’s highest peak, Mount Everest, became Internet friendly in 2010 when Ncell, a Nepalese telecom company, provided it with 3G data connection. Climbers can now find Wi-Fi hotspots all along the trek, to a height of 17,000 feet – the last point where you can take that envious selfie and update your social media status.

The Moon

The moon may not offer you breathable air but it does promise you a Wi-Fi hotspot! The feat was made possible by the researchers from MIT (Lincoln Laboratory) and NASA. Four separate telescopes were put in used to send signals to a satellite that revolves around the moon. This satellite had a receiver mounted on it. The scientists used a laser transmitter to beam data in the form of pulses of IR light through the four telescopes. The laser transmitter then transmits the IR rays to the telescope mounted on the satellite, which then collects and aims the beam into an optical fiber. These pulses are first converted into electrical pulses using a photodetector and then into data. This Wi-Fi hotspot makes it possible to transmit data between Earth and the moon at a rate of 19.44 mbps and to download it at a rate of 622 mbps.

The International Space Station (ISS)

If you are one of the lucky ones with a ticket to travel to the International Space Station, you don’t have to return back to Earth to share your experience with your friends. Yes, you guessed it right – the artificial satellite, ISS also has a Wi-Fi hotspot. The free internet works through the Ku-band, a satellite communications system that delivers output of around 10 mbps down and 3 mbps up from the space station.

The North Pole

Digital technology has made its presence felt in the remotest areas of the globe and the North Pole is no exception. One of the coldest places in the world, the North Pole too found Internet connectivity in 2005, when two Moscow-based Intel employees set up a Wi-Fi hotspot here, making it the first wireless connection in the Arctic region. They set up a wireless LAN connection with Intel Centrino mobile tech on four laptops and an 802.11b/g access point at the main camp site. The network connects to the internet via an Iridium satellite phone.

Mount Girnar

Mount Girnar, the tallest mountain in the Indian state of Gujrat is home to 30 temples and is a famous pilgrimage site. Pilgrim’s progress to the 1100-metre tall mountain was made Wi-Fi enabled making it easier for 25 lakh tourists to remain connected with their families, friends during the trek to the seven peaks of the mountain.

Remote Villages of UP (India)

The strong winds of the digital revolution that are sweeping through India, transformed the lives of 2000 villagers in the state of Uttar Pradesh in India, for whom, till then, the nearest telephone was 6 kms away.  The Indian Institute of Technology, Kanpur, as part of its Digital Gangetic Plain Project, ensured WiFi connectivity to 10 villages located near the Lucknow-Kanpur highway, making the area a lone island of connectivity in a sea of rural roads, rice fields and thatched roofs.

Cemeteries

Strange as it sounds but Oak Grove cemetery in Paducah, Kentucky has a free Wi-Fi hotspot.  The area was made Wi-Fi-enabled to allow visitors to conduct genealogy research and know more about the people who were buried there. On a similar note, free Wi-Fi connectivity is also provided in San José Cemetery in Granada, Spain.

Mount Fuji

The iconic Mount Fuji Mountain in Japan was made Internet-friendly with the launch of eight Wi-Fi spots all along the climb route including one on the summit. Officials say that the move was in response to the requests from American and European tourists who wanted to share their experiences with family and friends while on the move. Besides, the authorities also wanted to attract more visitors to the mountain.

Donkeys, Kfar Kedem, Israel

You read it right — Wi-Fi hotspots on donkeys! The innovative move was made a few years back in the historical amusement park in Israel. The park attempts to create life from the first and second centuries AD. The donkeys carry a small bag containing a router around their necks. The tourists can document their experience and share it on the social media.

Val d’Isere, France

If you are looking for the best selfies on a holiday, Val d’Isere, in France is a great place to head to. The place now offers a Wi-Fi gondola and so now you can take photos of the stunning views from your ski lift and post them straight to your Facebook.

National Parks, Canada

Canada has introduced several Wi-Fi spots in its national parks. Given the stunning beauty of these parks, the authorities are making them more Internet-friendly to attract more visitors and allow them to instantly share their experiences. While there, you will also be able to connect to GPS to get the most value from your visit.

Waikiki Beach, Hawaii, USA

Last but not least Waikiki Beach, Hawaii USA – using Altai SuperWifi products! For most people, a beach break is a way to get away from it all. However, if you can’t resist a peek into your social media or emails over the piña colada then Waikiki beach is for you. Along the sun and sand, you also have with Wi-Fi hotspots for company.

Critical Communication – Wi-Fi Underground Communications System

Share this PostShare on FacebookTweet about this on TwitterShare on LinkedInShare on Google+Email this to someone

Managing business requirements alongside safety for staff who work underground can be a sensitive balancing act, and one that you can’t afford to fail.

Because of this it is important to take advantage of improvements in technical and new product development aimed at reducing business costs, upgrading business information and improving staff safety.

The Wi-Fi Underground Communication System (UCS) was developed by Powertec Telecommunications in conjunction with our resellers for a specific client to improve their current method of communication when staff were traversing underground tunnels.

The final result produced great outcomes for the client – less staff required to do the task, better communication and improved safety. The Altai Super WiFi Underground Communication System was tested head to head with an alternative popular competitor and beat them across the board in terms of ease of operation, coverage and signal strength.

The Wi-Fi Underground Communication System Model

Overview

The client brief was to update communications when traversing through the network of underground tunnels by replacing the UHF push to talk/2way radio system used to communicate between the surface and the traverse teams.  The UHF system was used primarily for voice communications and was unreliable, with fairly sketchy service on occasion and only operated in shortWi-Fi Underground range.  These issues did not support robust health and safety outcomes, they placed limits on the amount of tunnel investigation work done underground in a single session, and did not allow widespread communication when issues forced further consultation with other company staff.

Powertec suggested that Wi-Fi be tested and worked with the partner client to arrive at the solution.  Wi-Fi initially had its own challenges – it had to operate above and below ground, the best frequency had to be determined and it needed to be reliable over some very adverse terrain.  One issue imperative to address was how to create a closed loop IP Network to allow handover from end to end.

Products20160420_160708

The UCS was pre-configured and provided as a boxed solution in a high impact Pelican suitcase.  Altai Super WiFi products were used due to their high quality carrier grade and proven performance to increase capacity and extend coverage.

  • Altai A2

The Altai A2 is a powerful access point/bridge solution with an integrated Wi-Fi Underground5GHz backhaul radio and antenna, designed for micro WiFi coverage and high throughput PTP/PTMP bridging. The A2 includes a MIMO 2.4GHz 801.11 b/g/n radio with a set of 2 antenna ports, and a MIMO 5GHz 802.11a/n radio with an integrated dual-slant high-gain antenna, making it a simple-to-deploy solution for remote micro coverage with integrated backhaul.

  • Altai C1an / C1xan

The C1an and C1xan are high-performance WAP’s designed to increase WiFi signal strength (transmission and reception) as well as the client’s throughput.  They can be configured as AP, STN, Repeater Bridge.

  • Rugged HSP/LTE routers
  • ICOM Handheld communication device

Proof of Concept

It was determined that using the 5ghz was the better frequency as it would tend to reflects of surfaces rather than penetrate – a benefit when working with underground tunnels that are not straight. All staff held an ICOM device that controlled the Wi-Fi push to talk system.

The test was conducted in a 1.8km stretch of tunnel with man hole access entrances at each end of the test section.  The Wi-Fi Undergroundtunnel was a dogleg shape.

An Altai A2 was winched down on a tripod via the access entrance at each end of the tunnel, positioned to face each other. A router was positioned at the top of each access entrance along with an Altai C1an for surface access.

The positioning of the Altai products above and below the ground produced a closed loop IP network that the ICOM Wi-Fi push to talk hand phones could operate on.

Traverse staff and rescue teams already work with a backpack carrying their required items and a modified battery powered Altai C1xan with external antennas was included (adding Wi-Fi Undergroundno more than 1kg to the total weight).  This acted as a repeater for the signal from the A2 that was positioned at the access point at the start of the tunnel entrance.  As the team traverses the tunnel doing their investigation, the C1xan within the backpack reaches a predetermined threshold and then hands over to the next A2.

The handover threshold in this instance occurred at 1250 metres into the tunnel from the starting point.

There are a number of ways to handle the movement of the Wi-Fi IP network and this case study would potentially move the 1st UCS components and leapfrog it to the 3rd access entrance. The 2nd UCS would then be turned around to face the 3rd and staff could begin their traverse of the new section.

Final Outcome

A typical above and below ground traverse team could comprise of: 2 teams tunnel traverse staff each supported by a rescue team, chemists, engineers, a communications specialist, and an underground rescue specialist.  It would not be uncommon for 24 people to spend the day investigating one 2km length of tunnel.  If there were any issues found, that number would grow as HQ staff and additional specialists may be needed at the site for consultation.

Utilising the Wi-Fi UCS could eliminate the need for engineers, chemists, management and other staff to be onsite.  The access to Wi-Fi now provides data from the underground traverse – vision, voice, video, monitoring, air quality sensors and more.

Communication can now be done with relevant management, chemists, and engineers, providing live access but no need for staff to leave their offices.  Project costs would be reduced.

The traverse can now be done in a reduced time.  It is possible that productivity could increase by over 200% (10km in one day instead of 2km).

Safety standards would improved for staff with access to live images and constant contact.

Application

The Wi-Fi Underground Communication System should result in cost savings, increased productivity and improved staff conditions – it has applications across a myriad of industries who manage the following kit:

  • Water pipe/sewerage monitoring
  • Underground tunnels
  • Gas pipe inspections
  • Lift shafts
  • Stormwater drains
  • Water tanks, gas tanks, ships
  • Building sites/high rise buildings
  • Underwater exploration (currently proof of concept stage)

Where you have a job that can be run from a packet switch network there is no need to send maximum people to do the work.  You can utilise vision and data from a UCS system to improve the access and save money.

Accommodation Park Wifi Case Study

Share this PostShare on FacebookTweet about this on TwitterShare on LinkedInShare on Google+Email this to someone

The mining company currently using the site for its FIFO workers noticed that the moral of the workers had increased greatly after the Park WiFi installation due to staff ability to maintain communications with family and friends back home.

Business Profile

The town of Wandoan is situated midway between Brisbane (389kms south east) and Rockhampton (376km North East).  Not a big town, at the 2011 census, Wandoan had a population of 665.  One notable Australian who grew up in the town is Australian, Queensland and Brisbane rugby league captain Darren Lockyer.

The town’s economy is traditionally (since 1853) based on agriculture, including wheat and cattle with mining for coal and gas, growing industries.

The Wandoan Accommodation Park, is just off the Leichhardt Highway on a very popular inland route north heading towards tropical Queensland.  The 3.5 acre landscaped Park caters for caravans and camping but also provides 3 to 4 star cabins, suites and apartments for those who prefer to maintain their standards whilst getting back to nature.

Business Needspark wifi

With the rise of mining in the area, the Wandoan Accommodation Park has of late been used to house mining staff while they work on site on a fly in, fly out basis.

It is usual for a fly in, fly out job to involve longer shifts with little recreation facilities available to staff. However to attract and retain staff, accommodation facilities now need to ensure there are improved after hours facilities available.  By and large, Wandoan Accommodation Park provided an excellent base for staff with a pool, restaurant, BBQ’s and more available to while away the hours while working and away from their homes and families.  The one area the Park did not excel in was provision of Park WiFi services.

Due to the construction of the accommodation the buildings (dongas), signal penetration with traditional access points was intermittent at best which lead to poor user experience.

Business Solution Park WiFi

After site visit and review by telecommunications expert Daniel Davis from Darktime Computer Services, coverage plans were produced and once agreed upon, install was undertaken.

Altai SuperWiFi Enables Digital Mining – Quick Wireless Solution for Coalfield Applications

Overview

In order to increase the productivity, safety and security of mining, staying abreast with the latest communication technology is the key to achieving these objectives.  The extreme environment of coalfields makes wireless connection an ideal solution for various applications since wireless can be deployed virtually anywhere.

Operated by Sainik Mining and Allied Services Limited (“Sainik’), the open-pit mines in Jharkhand of India urgently required a high capacity wireless broadband network to provide internet connection for its site offices, RFID tracking application as well as wireless video surveillance system.

Reliable and always available connectivity is crucial in the coalfield because when a data network shuts down or becomes unavailable, the entire operation will be suspended. Compared to wired solutions, wireless devices are easier to be replaced in the event of failure.

Owing to the rugged, dusty and ever changing landscape of the coalfield, Altai’s C1n series was selected to provide point-to-point wireless connection. With a total area of over 6 sq. km, the entire coalfield is fully covered by Altai SuperWiFi.

The Challenge

  • Dusty, rugged and ever changing landscape with limited sites for installation
  • Lack of Ethernet & Internet backbone
  • Network redundancy is required
  • The network must be expandable and easy to deploy
  • Extending live CCTV feeds from Control Rooms to ‘Coalfields WAN’ over Internet in phases

The Solution

In order to provide full outdoor WiFi coverage, C1n and C1an are Mining wifi 2mounted on towers to provide internet connection for RFID vehicle tracking application and central control room.

Operating on 5GHz channels, the C1xan’s are installed on different towers and rooftops of onsite offices to provide up to 6km point-to-point wireless connection for the video surveillance system. All the wireless CCTV cameras are connected to the central control room and the cameras are installed in strategic locations to avoid blind spots. Since the wireless network must be always available, another pair of C1xan are connected to provide network redundancy.

The Result

With high gain smart antennas and advanced signal processing algorithms, the Altai C1n series is able to provide long range coverage with high throughput. Owing to the ever changing landscape of open-pit mines, the compact and portable design of the C1n series enables the network operator to expand its WiFi network easily

The Altai Super Wi-Fi network is able to withstand the harsh environment of a coalfield to provide full network coverage for internet access, RFID vehicle tracking application and wireless video surveillance system.

Testimonial:

We found Altai point-point & point-multipoint radios a stable solution for Wireless CCTV backhaul, providing stable and sufficient bandwidth for IP CCTV Surveillance for real-time viewing. These Altai radios provide very high throughput in point-point, point-multipoint or daisy-chain topologies without impairing real-time viewing experience of high grade megapixel CCTV cameras.

PowertecWifi have trained operatives throughout Australia that can plan and assist you to set up a similar quick wireless solution for your mining application.
