Münchner Nahverkehr historisch (1)

Stammstrecke 2

Schon vor der Planung der zweiten Stammstrecke und vor dem Bau von S- und U-Bahn in München gab es Projekte, die den Nahverkehr beschleunigen sollten. Ein Projekt war die Schnellstraßenbahn, von der es (noch) einen Tunnel und ungenutzte Haltestellen gibt.

Warning: Red lights are already flashing.

Last week, a meeting of the European Communications Committee (ECC) was held in Vilnius (Lithuania). The ECC Decision (11) 03 which recommends the free use of CB and the application of the standard EN300433 (AM-FM 4W and 12W pep SSB) has been revised.

The ECBF and the AER participated in that meeting, denouncing the non-application of the Decision (11)03 in several countries member of the European Conference of Postal and Telecommunications Administrations (CEPT).

The most surprising thing was that some participants warned us of the „off the record“, that the countdown had started to make disappear the CB 27 MHz in less than 10 years.

The first step has been to delete the record of users.

A series of groups have forced several administrations to stop: to register, to issue licenses and authorizations. Several manufacturers and importers, influenced by these groups and with the belief of increasing their sales, have supported these measures.

As a result, if before CB had little or no protection from administrations against interference from other services being in industrial scientific and medical band, now that the administrations no longer know the number of users, what will happen in the future? If the users are no longer protected, it means more QRM in the 27 MHz band.

The next step will be in five years or sooner (every five years, decisions are revised by ECC). They will start to propose other uses of the 27 MHz band (it is already happening), and as there are no users and as it is an ICM band, they can easily declare the free frequency for any kind of use. In the next revision of the ECC Decision (11) 03, the little support to CB can simply be cancelled and disappear.

How can we avoid it? It has been suggested us that only the figures can stop this process; number of users, number of CB transceivers sold and manufactured, number of accessories, etc. We must provide these figures to the CEPT in order to justify the existence of a real market.

The administrations can’t facilitate the number of users, only the federations can provide this type of information. We must provide these numbers to the CEPT.

The other numbers belong to private industry, which datas are confidential and hard to get. We should try to get this type of information to continue giving life to the CB.

The ECBF has a lot of work ahead.

Shaping the Future with WAN alternatives : Sigfox, LoRaWAN & Weightless

Keleno

WAN is an emerging technology that offers several benefits compared to traditional technologies. Wireless network technologies such as WiFi, ZigBee, Bluetooth etc can handle only consumer applications of the Internet of Things (IoT), but many industrial, civic, and other IoT applications need to operate over vastly greater territory than these technologies. Even-though cellular and satellite machine-to-machine (M2M) technologies have traditionally filled this gap, but cost, power,and scalability concerns make these choices less appealing for the future. A number of low- power,wide-area networking (LP-WAN) alternatives have arisen that need careful consideration to address these wide-ranging IoT applications.

M2M connectivity options that combine low- power and long-range present huge opportunities. Civic infrastructure systems such as parking resources, traffic control, utilities monitoring and distribution control, and environmental monitoring are just a few. Agricultural uses such as monitoring of crop conditions and livestock movements need wide-area coverage. Asset monitoring and tracking, from taxicabs to…
