ALL IP by the short hairs-Part 1

ALL IP by the short hairs-Part 1

If we were to summarize the current situation in the ALL IP market, we would see that the migration from ISDN to ALL IP has reached a stage where the number of IP-based telephone connections has exceeded other fixed-line connections such as analog or ISDN. In contrast to other VoIP/SIP providers, Germany’s largest carrier has not been able to offer SIP trunk connections in the last year, thus...

There’s no need to look out of the train window anymore

A few weeks ago Renfe (Spanish train operator) launched their onboard entertainment platform for high speed trains called PlayRenfe. They have taken onboard Wi-Fi for passengers a huge step further with this platform that allows travelers to connect to a fast train’s Wireless LAN, using their own devices; tablets, PC’s, or Smart phones. Once connected passengers can watch films, series, read...

Wi-Fi MIMO scenario in extreme environmental conditions

Wi-Fi MIMO scenario in extreme environmental conditions

Wi-Fi networks with high performance are not only needed in offices but also in extreme environmental conditions such as cold stores. Nevertheless, dual band access points for office environments cannot be installed inside cold stores because of the extreme environmental conditions. However, special MIMO Wi-Fi antennas with IP 68 protection operate even under extreme conditions up to minus 40...

WiFi HaLow , what is this all about?

The definition of new wireless LAN standards is a continuous process for creating, as well as improving applications and for making them more secure. The best-known wireless LAN standards by IEEE are certainly 802.11n for wireless LAN applications up to 600 Mbit/s and of course the 802.11ac standards which have recently been  introduced into the market, allowing applications up to 6.7 Gbps....

WAN Optimization: Webcache and other options

Customer branch offices frequently find themselves with limited resources for WAN connectivity, this being a common problem associated to communications.  WAN optimization under these circumstances makes sense, as the rise in productivity results in improved end customer perception. Through different techniques, optimization reduces both infrastructure and bandwidth costs, allows for centralized...

Beyond Gigabit Ethernet on the LAN

Beyond Gigabit Ethernet on the LAN

The coming generation of enterprise Wi-Fi Access Points will allow higher than 1 Gbps sustained payload data rates between the radio interface and the wired network to which they are connected. For this reason, current LAN infrastructure, that is mostly Gigabit Ethernet over CAT5e cabling, will become the bottleneck on the LAN communications. The alternatives to overcome this bottleneck are...
