Each time we download an application, browse the Internet, read an email or watch something on YouTube on our smartphones, we’re using some type of wireless technology. For mobile networks this means 3G or 4G LTE. However, when it comes to our home or work environment, we’re probably using Wi-Fi. From 802.11a, endorsed in the 90s (reaching speeds of up to 54 Mbps over 5 GHz radio waves) to the...
The following example will probably clarify the issue we had last week regarding the alternative approaches to ALL IP solution. A system which is automatically provisioned with basic functions such as Internet access, registering SIP/VoIP accounts, and a setup for basic telephony should also provide Wi-Fi for guests and business partners. Guests can use Wi-Fi by entering a preshared key. It is...
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...
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 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...
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....
